COMMISSION IMPLEMENTING REGULATION (EU) No 503/2013  
of 3 April 2013  
on applications for authorisation of genetically modified food and feed in accordance with 
Regulation (EC) No 1829/2003 of the European Parliament and of the Council and amending 
Commission Regulations (EC) No 641/2004 and (EC) No 1981/2006  
(Text with EEA relevance)  
THE EUROPEAN COMMISSION,  
Having regard to the Treaty on the Functioning of the European 
Union,  
Having regard to Regulation (EC) No 1829/2003 of the 
European Parliament and of the Council of 22 September 
2003 on genetically modified food and feed (  1 ), and in 
particular Articles 5(7), 11(5), 17(7) and 23(5) thereof,  
After consulting the European Food Safety Authority,  
Whereas:  
(1) Regulation (EC) No 1829/2003 lays down Union 
procedures for the authorisation and supervision of 
genetically modified food and feed, including rules for 
the labelling of such food and feed. That Regulation 
provides for a scientific evaluation to be carried out on 
the risks that the genetically modified food or feed may 
present for human and animal health and, as the case 
may be, for the environment. It also provides that a 
genetically modified food or feed must not mislead the 
consumer or the user and must not differ from the food 
or feed which it is intended to replace to such an extent 
that its normal consumption would be nutritionally 
disadvantageous for humans or animals.  
(2) Regulation (EC) No 1829/2003 provides, in particular, 
that applications for authorisation are to adequately 
and sufficiently demonstrate that the genetically modified food and feed satisfy the requirements laid 
down in that Regulation, in respect of their proposed 
uses.  
(3) In the interest of consistency of Union legislation, certain 
definitions laid down in Regulation (EC) No 178/2002 of 
the European Parliament and of the Council of 28 January 
2002 laying down the general principles and 
requirements of food law, establishing the European 
Food Safety Authority and laying down procedures in 
matters of food safety (  2 ) should also apply to this Regu ­
lation.  
(4) Commission Regulation (EC) No 641/2004 (  3 ) on 
detailed rules for the implementation of Regulation (EC) 
No 1829/2003 provides for certain detailed rules 
concerning applications for authorisation submitted in 
accordance with Regulation (EC) No 1829/2003. To 
facilitate the preparation of applications and ensure that 
they contain all the information needed for their 
assessment, it is necessary to provide for more compre ­
hensive and systematic rules concerning applications for 
authorisation, which should also be specific to each type 
of genetically modified organisms (GMO), namely plants, 
animals and micro-organisms.  
(5) The rules laid down in this Regulation should only cover 
applications concerning genetically modified plants for 
food or feed uses, food or feed containing or consisting 
of genetically modified plants and food or feed produced 
from such plants. Genetically modified plants, for which 
sufficient experience is available to date, constitute the 
vast majority of current applications.EN 8.6.2013 Official Journal of the European Union L 157/1  
( 1 ) OJ L 268, 18.10.2003, p. 1.  ( 2 ) OJ L 31, 1.2.2002, p. 1.  
( 3 ) OJ L 102, 7.4.2004, p. 14.(6) The rules laid down in this Regulation should specify the 
general requirements for the presentation and prep ­
aration of applications, namely requirements to provide 
general and scientific information, including methods for 
detection, and identification, as well as reference material 
so as to ensure that applications comply with the 
conditions laid down in Articles 5, 17 and 30 of Regu ­
lation (EC) No 1829/2003.  
(7) The applicant should also take into consideration the 
scientific information to be provided in the application 
as regards the environmental risk assessment of GMOs or 
food and feed containing or consisting of GMOs, as set 
out in the principles for the environmental risk 
assessment in Annex II to Directive 2001/18/EC of the 
European Parliament and of the Council of 12 March 
2001 on the deliberate release into the environment of 
genetically modified organisms and repealing Council 
Directive 90/220/EEC (  1 ), as well as the applicable 
guidance published by the European Food Safety 
Authority (EFSA) in this regard.  
(8) In addition to the general requirements for the presen ­
tation and preparation of applications, it is appropriate to 
provide for specific rules to ensure that the scientific 
information required in the application adequately and 
sufficiently demonstrates that the genetically modified 
food or feed satisfy the requirements laid down in Regu ­
lation (EC) No 1829/2003, in respect of their proposed 
uses.  
(9) These rules should therefore provide for a set of studies 
that should be included in all applications, as well as the 
test methods to be followed to perform such studies, 
whilst taking into account relevant international stan ­
dards, such as the guideline of the Codex Alimentarius 
for the conduct of safety assessment of foods derived 
from the recombinant-DNA plant (  2 ). 
(10) In accordance with the applicable guidance of the 
EFSA (  3 ), the safety assessment of the genetically 
modified food or feed should include studies related to 
new components resulting from the genetic modification, 
the molecular characterisation of the genetically modified 
plant, the comparative analysis of the composition and 
the phenotype of the genetically modified plant 
compared to its conventional counterpart. Depending 
on the characteristics of the genetically modified plant 
and on the outcome of that first set of studies, the 
EFSA guidance indicates that it may be necessary to 
perform additional studies. In that respect, the EFSA 
considers that notwithstanding its limitations, a 90-day 
feeding study in rodents with whole food or feed is, 
when justified, the primary additional study to address 
uncertainties identified in the course of the safety 
assessment.  (11) It has, however, not been proved possible to define with 
the necessary precision the level of uncertainties which 
would require the submission of 90-day feeding studies. 
In addition, some food and feed assessment bodies of 
Member States are of the opinion that such study 
should be performed in all applications for genetically 
modified plants containing single transformation events. 
Considering these diverging views, as well as to improve 
consumer confidence, such studies should be, for the 
time being, requested in all applications related to 
genetically modified plants with single transformation 
events and, where appropriate, on genetically modified 
plants containing stacked transformation events.  
(12) Studies to demonstrate that a genetically modified food 
or feed fulfils the requirements of Regulation (EC) 
No 1829/2003 involving the use of laboratory animals 
should be carried out in accordance with Directive 
2010/63/EU of the European Parliament and of the 
Council of 22 September 2010 regarding the protection 
of the animals used for scientific purposes (  4 ), and should 
be kept to a minimum while ensuring an adequate 
demonstration of the safety of the genetically modified 
food or feed. The current uncertainties in relation to the 
need and design of 90-day feeding trials will be addressed 
by a large research project under the 2012 work 
programme of Theme 2 ‘Food, Agriculture and Fisheries, 
and Biotechnologies’ of the seventh Framework 
Programme for Research (FP7). The requirements 
regarding animal feeding trials in the context of GMO 
risk assessments should be reviewed in the light of the 
outcome of this project expected to be available by the 
end of 2015 at the latest. Other credible scientific 
knowledge which might be available at that time 
should also be taken into account.  
(13) While the rules laid down in this Regulation should be 
valid for all applications for genetically modified plants, 
the type and necessity of the studies to evaluate the char ­
acteristics and safety of genetically modified food or feed 
subject to an application may vary, depending on the 
nature of the genetic modification or of the product. 
For example, genetic modifications which have negligible 
impact on the composition of a genetically modified 
food or feed or highly refined products that may be 
proven to be identical to products produced from the 
conventional counterpart require different studies than 
a product resulting from complex genetic modification 
aiming to modify its nutritional characteristics.  
(14) The requirements laid down in this Regulation regarding 
the studies which have to be included in an application 
for authorisation under Regulation (EC) No 1829/2003 
should not prevent the EFSA to request, where appro ­
priate, the applicant to supplement the particulars 
accompanying the application in accordance 
with Articles 6(2) and 18(2) of Regulation (EC) 
No 1829/2003.EN L 157/2 Official Journal of the European Union 8.6.2013  
( 1 ) OJ L 106, 17.4.2001, p. 1.  
( 2 ) Codex Alimentarius Commission, GL 45-2003.  
( 3 ) EFSA Journal 2011; 9(5):2150.  (  4 ) OJ L 276, 20.10.2010, p. 33.(15) In order to ensure that studies are of high quality and 
documented in a transparent way, it is essential that they 
are performed under appropriate quality assurance 
systems and raw data should be provided in all cases 
and be in a suitable electronic format. Toxicological 
studies should be performed in accordance with the 
quality assurance principles laid down by Directive 
2004/10/EC of the European Parliament and of the 
Council of 11 February 2004 on the harmonisation of 
laws, regulations and administrative provisions relating to 
the application of the principles of good laboratory 
practice and the verification of their applications for 
tests on chemical substances (  1 ). If such studies are 
carried out outside the Union, they should follow the 
state-of-the-art OECD Principles on Good Laboratory 
Practice (GLP). With regard to studies other than toxico ­
logical studies, they should be conducted under ISO or 
GLP standards.  
(16) It is also necessary to define the requirements regarding 
the submission of additional information related to the 
safety of the GMO and scientific peer-reviewed literature 
related to the potential effects on health and on the 
environment of the products covered by the application.  
(17) During the process of the genetic modification of plants 
and other organisms, marker genes are often used to 
facilitate the selection and identification of genetically 
modified cells, containing the gene of interest inserted 
into the genome of the host organism, among the vast 
majority of untransformed cells. Such marker genes 
should be carefully selected. In addition, it is now 
possible to develop GMOs without the use of antibiotic 
resistance marker genes. Against this background and in 
accordance with Article 4(2) of Directive 2001/18/EC, 
the applicant should therefore aim to develop GMOs 
without the use of antibiotic resistance marker genes.  
(18) The harvest of segregating genetically modified plants 
(segregating crops) containing stacked transformation 
events contains various subcombinations of trans ­
formation events. In addition, current control procedures 
do not allow identifying the origin of combinations of 
transformation events. Therefore, in order to ensure that 
authorisations are coherent with the products of which 
the placing on the market is unavoidable and for the 
feasibility of controls, the applications for genetically 
modified food and feed from segregating crops should 
include all subcombinations independently of their origin 
and not yet authorised.  
(19) Regulation (EC) No 1829/2003 provides that a proposal 
for post-market monitoring of the use of the genetically 
modified food or feed shall only be submitted by the 
applicant where it is appropriate. It is therefore 
necessary to set out the conditions under which such a 
proposal should, according to the outcome of the risk 
assessment, accompany the application. Post-market monitoring should only be considered in cases where, 
notwithstanding the fact that the safety of genetically 
modified food and feed has been demonstrated, it is 
appropriate to confirm the expected consumption, the 
application of conditions of uses or identified effects. 
This is for example the case when the genetically 
modified food or feed has altered nutritional composition 
or when that its nutritional value differs from the 
conventional food or feed that it would replace or 
when there is a likelihood of increased allergenicity due 
to the genetic modification.  
(20) This Regulation should take account of the international 
trade commitments of the Union and of the requirements 
of the Cartagena Protocol on Biosafety to the Convention 
on Biological Diversity (the Cartagena Protocol), 
approved by Council Decision 2002/628/EC of 25 June 
2002 concerning the conclusion, on behalf of the 
European Community, of the Cartagena Protocol on 
Biosafety (  2 ) as well as the provisions of Regulation 
(EC) No 1946/2003 of 15 July 2003 of the European 
Parliament and of the Council on transboundary 
movements of genetically modified organisms (  3 ). 
(21) In order to ensure that test methods included in the 
application are adequate to demonstrate that the food 
or feed complies with the requirements for authorisation 
set out in Regulation (EC) No 1829/2003, they should be 
carried out in accordance with the present Regulation, or 
internationally agreed guidelines such as those described 
by the OECD, when available. To ensure that applications 
for renewal meet the same standards as regards tests 
methods, it is appropriate that these requirements also 
apply to application for renewal of authorisation of GM 
food and feed.  
(22) In order to provide an accurate designation of the GM 
food or feed subject to an application under Regulation 
(EC) No 1829/2003, applications should include 
proposals for a unique identifier for each GMO 
concerned in accordance with Commission Regulation 
(EC) No 65/2004 of 14 January 2004 establishing a 
system for the development and assignment of unique 
identifiers for genetically modified organisms (  4 ). 
(23) This Regulation replaces certain provisions of Regulation 
(EC) No 641/2004 as regards genetically modified plants 
for food or feed uses, food or feed containing or 
consisting of genetically modified plants and food or 
feed produced from genetically modified plants. 
However, Regulation (EC) No 641/2004 should 
continue to apply as regards other types of genetically 
modified products, namely genetically modified animals 
and genetically modified micro-organisms. Moreover, 
certain provisions of that Regulation are obsolete. Regu ­
lation (EC) No 641/2004 should therefore be amended 
accordingly.EN 8.6.2013 Official Journal of the European Union L 157/3

tation of Article 32 of Regulation (EC) No 1829/2003 of 
the European Parliament and of the Council as regards 
the Community reference laboratory for genetically 
modified organisms (  1 ) should be amended to include 
references to this Regulation.  
(25) Regulation (EC) No 1829/2003 provides that the 
Commission is to consult the EFSA before establishing 
implementing rules with regard to the applications for 
authorisation under that Regulation. The EFSA has been 
consulted on those rules accordingly.  
(26) This Regulation has been drawn up on the basis of 
current scientific and technical knowledge. Therefore, 
the Commission should monitor any developments in 
this field and the publication of new or additional 
guidance by the EFSA.  
(27) This Regulation applies to applications submitted after its 
entry into force. It is necessary to provide for transitional 
measures in order to enable the applicants to comply 
with those rules and for the current applications or the 
applications close to being submitted to proceed without 
unnecessary delays.

SCIENTIFIC REQUIREMENTS FOR THE RISK ASSESSMENT OF GENETICALLY MODIFIED FOOD AND FEED  
I. INTRODUCTION  
1. DEFINITIONS  
For the purpose of this Annex, the following definitions shall apply:  
1. ‘hazard identification’ means the identification of biological, chemical and physical agents capable of causing 
adverse health effects and which may be present in a particular food and feed or group of foods and feeds;  
2. ‘hazard characterisation’ means the qualitative and/or quantitative evaluation of the nature of the adverse 
health effects associated with biological, chemical and physical agents which may be present in food and feed;  
3. ‘risk characterisation’ means the qualitative and/or quantitative estimation, including attendant uncertainties, of 
the probability of occurrence and severity of known or potential adverse health effects in a given population 
based on hazard identification, hazard characterisation and exposure assessment.  
2. SPECIFIC CONSIDERATIONS  
2.1. Insertion of marker genes and other nucleic acid(s) sequences not essential to achieve the desired trait  
In order to facilitate the risk assessment, the applicant shall endeavour to minimise the presence of inserted 
nucleic acid(s) sequences not essential to achieve the desired trait.  
During the process of genetic modification of plants and other organisms, marker genes are often used to 
facilitate the selection and identification of genetically modified cells, containing the gene of interest inserted into 
the genome of the host organism, among the vast majority of untransformed cells. The applicant shall carefully 
select such marker genes and Article 4(2) of Directive 2001/18/EC shall be respected. Against that background, 
the applicant shall therefore aim to develop GMOs without the use of antibiotic resistance marker genes.  
2.2. Risk assessment of genetically modified food and feed containing stacked transformation events  
For the risk assessment of genetically modified food and feed containing stacked transformation events obtained 
by conventional crossing of genetically modified plants containing one or several transformation event(s), the 
applicant shall provide a risk assessment of each single transformation event or, in accordance with Article 3(6) 
of this Regulation, refer to already submitted application(s). The risk assessment of genetically modified food and 
feed containing stacked transformation events shall also include an assessment of the following aspects:  
(a) stability of the transformation events;  
(b) expression of the transformation events;  
(c) potential synergistic or antagonistic effects resulting from the combination of the transformation events shall 
be subject to an assessment in accordance with Sections 1.4 (Toxicology), 1.5 (Allergenicity) and 1.6 
(Nutritional assessment).  
For genetically modified food and feed containing, consisting of or produced from genetically modified plants, 
whose cultivation is associated with the production of genetically modified material containing various subcom ­
binations of transformation events (segregating crops), the application shall include all subcombinations indepen ­
dently of their origin which have not yet been authorised. In such a case, the applicant shall provide a scientific 
rationale justifying that there is no need to provide experimental data for the concerned subcombinations or, in 
the absence of such scientific rationale, provide the experimental data.  
For genetically modified food and feed containing, consisting of or produced from genetically modified plants, 
the cultivation of which does not lead to the production of genetically modified material containing various 
combinations of transformation events (non-segregating crops), the application shall only cover the combination 
which is to be placed on the market.  
The rules set out in this Section apply  mutatis mutandis  to transformation events which are combined by other

For example, when the introduced trait is herbicide tolerance, the applicant shall provide information on the 
mode of action of the active substance and its metabolism in the plant.  
1.2.2.2. Information on the sequences actually inserted/deleted  
The applicant shall provide the following information:

that could be inserted into the genetically modified plant, such as any parts of the plasmid/vector or any 
carrier or foreign nucleic acid(s) remaining in the genetically modified plant.  
The Southern analysis shall span the entire transgenic locus(i) as well as flanking sequences and include all 
appropriate controls.  
For the determination of copy number of the insert, complementary methods may also be used (such as real- 
time PCR);EN 8.6.2013 Official Journal of the European Union L 157/21(b) the organisation and sequence of the inserted genetic material at each insertion site in a standardised

site, with the aim of identifying interruptions of known genes.  
Bioinformatic analyses shall be conducted using up-to-date databases with the aim of performing both 
intraspecies and interspecies similarity searches.  
In the case of genetically modified plants containing stacked transformation events, the safety of potential 
interactions between any unintended modifications at each insertion site shall be assessed;  
(f) Open Reading Frames (hereafter referred to as ‘ORFs’ and defined as any nucleotide sequence that contains a 
string of codons that is uninterrupted by the presence of a stop codon in the same reading frame) created as 
a result of the genetic modification either at the junction sites with genomic DNA or due to internal 
rearrangements of the insert(s).  
The ORFs shall be analysed between stop codons, not limiting their lengths. Bioinformatic analyses shall be 
conducted to investigate possible similarities with known toxins or allergens using up-to-date databases.  
The characteristics and versions of the databases shall be provided.  
Depending on the information gathered, further analyses (such as transcription analysis) may be needed to 
complete the risk assessment.  
1.2.2.3. Information on the expression of the insert(s)  
The applicant shall provide information:  
— to demonstrate whether the inserted/modified sequence results in intended changes at the protein, RNA 
and/or metabolite levels;  
— to characterise the potential unintended expression of new ORFs identified under point 1.2.2.2(f) as raising a 
safety concern.  
For those purposes, the applicant shall provide the following information:  
(a) The method(s) used for expression analysis together with their performance characteristics;  
(b) Information on developmental expression of the insert during the life cycle of the plant.  
The requirement for information on developmental expression shall be considered on a case-by-case basis 
taking into account the promoter used, the intended effect(s) of the modification and scope of the appli ­
cation;  
(c) Parts of the plant where the insert/modified sequences are expressed;  
(d) Potential unintended expression of new ORFs identified under point 1.2.2.2(f) which raise a safety concern;  
(e) Protein expression data, including the raw data, obtained from field trials and related to the conditions in 
which the crop is grown.  
Data on expression levels from those parts of the plant used for food and feed purposes shall be provided in 
all cases.EN L 157/22 Official Journal of the European Union 8.6.2013In addition, information shall also be provided on the expression of target genes in other parts of the plant 
when tissue-specific promoters have been used and when this is relevant for the safety assessment. The 
minimum requirement for protein expression shall be data provided from three growing sites or from one 
site over three seasons. Permutations of the sites and seasons shall be acceptable provided that the minimum 
requirement is met. When justified by the nature of the insert (such as silencing approaches or where 
biochemical pathways have been intentionally modified), specific RNA(s) or metabolite(s) shall be analysed.  
For silencing approaches by RNAi expression, potential ‘off target’ genes should be searched by  in silico  
analysis to assess if the genetic modification could affect the expression of other genes which raise safety 
concerns;  
(f) With regard to the stacking of transformation events by conventional crossing, expression data shall be 
provided to assess the potential interactions between the events which may raise any additional safety 
concerns over protein and trait expression compared with the single transformation events. The comparison 
shall be carried out with data obtained from plants grown in the same field trials. On a case-by-case basis, 
and where concerns arise, additional information may be necessary.  
1.2.2.4. Genetic stability of the insert and phenotypic stability of the genetically modified plant  
The applicant shall provide information:  
(a) to demonstrate the genetic stability of the transgenic locus(i) and the phenotypic stability and inheritance 
pattern(s) of the introduced trait(s);  
(b) in case of stacked transformation events, to establish that each of the transformation events stacked in the 
plant has the same molecular properties and characteristics as in the plants with the single transformation 
events.  
For the purposes of that information, applicants shall provide data which demonstrate stability over multiple 
(normally five) generations or vegetative cycles for plant containing single transformation events. Data from the 
first and the last generations of vegetative cycles are sufficient. The source of the material used for the analysis 
shall be specified. Data shall be analysed using appropriate statistical methods.  
For stacked transformation events comparisons between the original transformation events and the stacked 
transformation events shall be carried out using plant materials representative of those designed for commercial 
production. The applicant shall provide adequate justification for the plant materials used. Comparisons shall 
include comparisons of sequences of the inserts and the flanking regions obtained from GM plants containing 
single events and plants containing stacked transformation events.  
To assess genetic stability of the transformation event(s), applicants shall use appropriate molecular approaches 
referred to in Section 1.2.2.2.  
1.2.2.5. Potential risk associated with horizontal gene transfer  
The applicant shall assess the probability of horizontal gene transfer from the product to humans, animals and 
micro-organisms and any potential associated risk when intact and functional nucleic acid(s) remains in the 
genetically modified food and feed.  
1.2.3.  Conclusions of the molecular characterisation  
The molecular characterisation shall provide data on the structure and expression of the insert(s), and on the 
stability of the intended trait(s). This shall also apply to situations where transformation events have been stacked 
by conventional breeding.  
It shall be specifically indicated whether the molecular characterisation of the genetic modification(s) raises safety 
concerns with regard to the interruption of endogenous genes or regulatory sequences.  
The molecular characterisation shall also aim to identify whether the genetic modification(s) raise(s) any issues 
regarding the potential for producing proteins/substances other than those intended and in particular new toxins 
or allergens.  
The potential unintended changes identified in this Section shall be addressed in the relevant complementary 
part(s) of the safety assessment.EN 8.6.2013 Official Journal of the European Union L 157/231.3.  Comparative analysis  
The comparative analysis of composition and agronomic as well as phenotypic characteristics shall constitute, 
together with the molecular characterisation, the starting point to structure and conduct the risk assessment of a 
new genetically modified food and feed.  
It shall aim at identifying similarities and differences:  
(a) in composition, agronomic performance and phenotypic characteristics (intended and unintended alterations) 
between the genetically modified plant and its conventional counterpart;  
(b) in composition between the genetically modified food and feed and its conventional counterpart.  
Where no appropriate conventional counterpart can be identified, a comparative safety assessment cannot be 
made and consequently a safety and nutritional assessment of the genetically modified food or feed shall be 
carried out as for novel foods falling within the scope of Regulation (EC) No 258/97 of the European Parliament 
and of the Council (  1 ) that do not have conventional counterparts (such as where the genetically modified food 
or feed is not closely related to a food or feed with a history of safe use or where a specific trait or specific traits 
are introduced with the intention of bringing complex changes in the composition of the genetically modified 
food or feed).  
1.3.1.  Choice of the conventional counterpart and additional comparators  
In the case of vegetatively propagated crops, the conventional counterpart shall, in principle, be the near-isogenic 
variety used to generate the transgenic line.  
In the case of crops that reproduce sexually, the conventional counterpart shall have a genetic background 
comparable to the genetically modified plant. When the GM plant has been developed using back-crossing, a 
conventional counterpart with a genetic background that is as close as possible to the genetically modified plant 
shall be selected.  
In addition, the applicant may include a comparator having a closer genetic background to the genetically 
modified plant than the conventional counterpart (such as a negative segregant).  
In the case of herbicide tolerant genetically modified plants and in order to assess whether the expected 
agricultural practices influence the expression of the studied endpoints, three test materials shall be compared: 
the genetically modified plant exposed to the intended herbicide; the conventional counterpart treated with 
conventional herbicide management regimes; and the genetically modified plant treated with the same conven ­
tional herbicide management regimes.  
In the case of stacked transformation events, it is not always possible to use a conventional counterpart with a 
genetic background as close to the genetically modified plant as with conventional counterpart normally used for 
single transformation events. In such circumstances, the applicant shall provide reasoned justification on the 
choice of the conventional counterpart and assess its limitations for the risk assessment. In addition, single 
parental genetically modified lines or genetically modified lines containing a subcombination of the stacked 
transformation events for which an application has been submitted or negative segregants derived from these 
genetically modified lines may also be included as additional comparators. The applicant shall provide detailed 
information justifying the choice of additional comparators.  
In all cases, the applicant shall provide information on the breeding scheme (pedigree) in relation to the 
genetically modified plant, the conventional counterpart and, where appropriate, additional comparators 
together with an adequate justification of their selection. The history of safe use of the conventional counterpart 
shall be adequately supported by both qualitative and quantitative data.  
More detailed guidance for the application of the requirements of this Section is available in the EFSA scientific 
opinion ‘Guidance on selection of comparators for the risk assessment of genetically modified plants and derived 
food and feed’ (  2 ).EN L 157/24 Official Journal of the European Union 8.6.2013  
( 1 ) OJ L 43, 14.2.1997, p. 1.  
( 2 ) EFSA Journal 2011; 9(5):2149.1.3.2.  Experimental design and statistical analysis of data from field trials for comparative analysis  
1.3.2.1. Description of the protocols for the experimental design  
(a) Principles of experimental design  
Field trials used for the production of material for the comparative analysis shall be performed in order to 
determine whether the genetically modified plant and/or the genetically modified food and feed is different 
from its conventional counterpart and/or equivalent to non-genetically modified reference varieties with a 
history of safe use.  
For each endpoint, the comparative analysis shall involve the following two approaches:  
(i) a test of difference, to verify whether the genetically modified plant is different from its conventional 
counterpart and might therefore be considered a hazard depending on the type of the identified 
difference, and on the magnitude and type of exposure;  
(ii) a test of equivalence to verify whether the genetically modified plant is equivalent or not to non- 
genetically modified reference varieties, apart from the introduced trait(s).  
In testing for difference, the null hypothesis shall be that there is no difference between the GMO and its 
conventional counterpart against the alternative hypothesis that a difference exists.  
Where additional comparator(s) are used for the risk assessment, a test of difference shall be carried out 
between the genetically modified plant and each of the additional comparator(s) following the requirements 
set out in Section 1.3.2.2 for the test of difference between the genetically modified plant and its conven ­
tional counterpart.  
In testing for equivalence, the null hypothesis shall be that the difference between the GMO and the set of 
reference varieties is at least as great as a specified minimum size (see Section 1.3.2.2) against the alternative 
hypothesis that there is no difference or a smaller difference than the specified minimum between the GMO 
and the set of reference varieties.  
Rejection of the null hypothesis shall be required in order to conclude that the GMO and the set of reference 
varieties are unambiguously equivalent for the endpoint considered. The equivalence limits used for the test 
of equivalence shall represent appropriately the range of natural variation expected for reference varieties with 
a history of safe use.  
(b) Specific protocols for experimental design  
Natural variation may have several sources: variation within a variety arises due to environmental factors and 
variation between varieties arises due to a combination of both genetic and environmental factors. In order 
to identify and estimate differences attributable only to genotypes, it is essential to control environmental 
variability. Therefore, non-genetically modified reference varieties shall be included in the experimental design 
of the field trials and in sufficient numbers to ensure an adequate estimate of the variability required to set 
the equivalence limits. All test materials consisting of genetically modified plants, conventional counterpart, 
reference varieties and, where appropriate, additional comparator(s) shall be randomised to plots within a 
single field at each site, usually in a completely randomised or randomised block experimental design. The 
different sites selected for the field trials shall reflect the different meteorological and agronomic conditions 
under which the crop is to be grown; the choice shall be explicitly justified. The choice of non-genetically 
modified reference varieties shall be appropriate for the chosen sites and shall be justified explicitly. In the 
case the sites cover a restricted range of growing conditions, the applicant shall replicate the field trials over 
more than one year.  
Within each site the test materials consisting of genetically modified plants, conventional counterpart and, 
where appropriate, additional comparator(s) shall be identical for all replicates. In addition, unless there is 
explicit justification for not doing so, at each site there shall be at least three appropriate non-genetically 
modified reference varieties of the crop that have a known history of safe use, which shall also be identical 
between replicates. The replication at each site is the number of results obtained for each test material; the 
replication should never be less than four at any site. However, if only two appropriate reference varieties are 
available at a particular site, then the replication shall be six at that site; if only one is available then the 
replication shall be eight.EN 8.6.2013 Official Journal of the European Union L 157/25Each field trial shall be replicated at a minimum of eight sites, chosen to be representative of the range of 
likely receiving environments where the plant is to be grown. The field trials may be conducted in a single 
year, or spread over multiple years. The non-genetically modified reference varieties may vary between sites 
and at least six different reference varieties shall be used over the entire set of field trials.  
When the genetically modified plant is tested together with other genetically modified plants of the same 
crop species (such as  Zea mays ) the production of material for the comparative assessment of these different 
genetically modified plant may be produced simultaneously at the same site and within the same field trial by 
the placing of the different genetically modified plants and their appropriate comparator(s) in the same 
randomised block. This shall be subject to the following two strict conditions:  
(i) the conventional counterpart and, where appropriate, additional comparator(s) shall always occur 
together with the genetically modified plant in the same block;  
(ii) all the different genetically modified plants and their comparator(s) and all the non-genetically modified 
reference varieties used to test equivalence with those genetically modified plants shall be fully 
randomised within each block.  
If the number of plots per block required for such a field trial were to exceed 16, then a partially balanced 
incomplete block design may be used, to reduce the number of plots per block, by excluding some of the 
genetically modified plants and their appropriate comparator(s) from each block. This shall be subject to the 
following two strict conditions:  
(i) the conventional counterpart shall always occur together with its particular genetically modified plant in 
the same block;  
(ii) all of the non-genetically modified reference varieties shall appear in each of the incomplete blocks and 
be fully randomised with the plants and their comparator(s).  
The field trials shall be adequately described, giving information on important parameters such as 
management of the field before sowing, date of sowing, soil type, herbicide use, climatic and other culti ­
vation/environmental conditions during growth and time of harvest, as well as the conditions during storage 
of the harvested material.  
More detailed guidance for the application of the requirements of this Section is available in the EFSA 
opinion on ‘Statistical considerations for the safety evaluation of GMOs’ (  1 ). 
1.3.2.2. Statistical analysis  
Analysis of data shall be presented in a clear format, using standardised scientific units. The raw data and the 
programming code used for the statistical analysis shall be given in an editable form.  
Data transformation may be necessary to ensure normality and to provide an appropriate scale on which 
statistical effects are additive. For many endpoint response variables, a logarithmic transformation is expected 
to be appropriate. In such cases, any difference between the genetically modified material and any other test 
material shall be interpreted as a ratio on the natural scale. However, when logarithmic transformation does not 
provide appropriate results, the natural scale or another scale shall be considered.  
The total variability of each endpoint observed in the field trials shall be estimated and partitioned using 
appropriate statistical models in order to derive two sets of confidence limits and to set a lower and upper 
equivalence limit based on the variability observed among the reference varieties. One set of confidence limits 
shall be used in the test of difference; the other set and the equivalence limits shall be used in the test of 
equivalence.  
A linear mixed statistical model shall be used for calculation of the confidence limits for both tests (that is to say, 
the difference and equivalence tests); a slightly different model shall be used to estimate the equivalence limits to 
be used in the equivalence test.EN L 157/26 Official Journal of the European Union 8.6.2013  
( 1 ) EFSA Journal 2010; 8(1):1250.Denote by  I an indicator variable (uncentered in the mixed model) such that  I = 1 for a field plot having any of 
the non-GM reference varieties, and  I = 0 otherwise. Then the random factors for model 1 should be, but not 
necessarily be restricted to, those representing the variation: (i) between the test materials (a set that includes the 
GM plant, its conventional counterpart, each of the non-GM reference varieties and any additional comparators); 
(ii) in the interaction between the test materials and  I; (iii) between sites; and (iv) between blocks within sites. 
Model 2 should be identical to model 1 except that the random factor representing the interaction between the 
test materials and  I is omitted.  
The fixed factor for both models should have as many levels as there are test materials and represent the 
contrasts between the means of the test materials. The test materials are as defined above: the GM plant; its 
conventional counterpart; the set of non-GM reference varieties; and any additional test materials. The set of non- 
GM reference varieties is considered as a single level of the fixed factor. For the difference test, the component of 
the fixed factor of interest is the single degree-of-freedom contrast between the GM plant and its conventional 
counterpart. For the equivalence test, the component of the fixed factor of interest is the single degree-of-freedom 
contrast between the GM plant and the set of non-GM reference varieties.  
Both the difference test and the equivalence test shall be implemented using the correspondence between 
hypothesis testing and the construction of confidence limits. In the case of equivalence testing, the approach 
used shall follow the two one-sided tests (TOST) methodology by rejecting the null hypothesis of non-equiv ­
alence when the both confidence limits fall between the equivalence limits. The choice of 90 % confidence limits 
corresponds to the customary 95 % level for statistical testing of equivalence.  
The results of the difference and equivalence tests shall be represented visually for all the endpoints simulta ­
neously, on a single graph or a few graphs.  
The graph(s) shall show the line of zero difference between the genetically modified material and its conventional 
counterpart, and for each endpoint: the lower and upper adjusted equivalence limits; the mean difference 
between the genetically modified material and its conventional counterpart; and the confidence limits for this 
difference (see the set of possible outcomes for a single endpoint in the graph in Figure 1).  
When, in addition to the conventional counterpart, another test material is used as comparator, the mean 
difference between the genetically modified material and that comparator, its confidence limits and its 
adjusted equivalence limits shall be displayed on the graph(s), for all such additional comparators, by 
referring this to the same zero baseline as defined by the conventional counterpart. The line of zero difference 
on the logarithmic scale corresponds to a multiplicative factor of unity on the natural scale. The horizontal axis 
shall be labelled with values that specify the change on the natural scale. In the case of logarithmic trans ­
formation, changes of 2x and ½x will appear equally spaced on either side of the line of zero difference.  
Despite the expected proportion of spurious significant differences, the applicant shall report and discuss all 
significant differences observed between the genetically modified crop, its conventional counterpart and, where 
applicable, any other test material, focusing on their biological relevance (see Section 3 on Risk Characterisation).  
For reporting, full details shall be given for each endpoint analysed, listing:  
(a) the assumptions underlying the analysis;  
(b) full specification of the mixed models chosen, including fixed and random effects;  
(c) results of any test of interaction between the test materials and sites;  
(d) fixed effects, together with the appropriate estimated residual variation with which they are compared, and 
variance components for the random factors;  
(e) estimated degrees of freedom;  
(f) any other relevant statistics.  
A discussion on the likely impact of other growing conditions not tested in the field trial shall be provided.EN 8.6.2013 Official Journal of the European Union L 157/27Figure 1:  simplified version of a graph for comparative assessment showing the seven outcome types possible for 
each single endpoint. After adjustment of the equivalence limits, a single confidence limit (for the difference) 
serves visually for assessing the outcome of both tests (difference and equivalence). Here, only the upper adjusted 
equivalence limit is considered. Shown are: the mean of the genetically modified crop on an appropriate scale 
(square); the confidence limits (whiskers) for the difference between the genetically modified crop and its 
conventional counterpart (bar shows confidence interval); a vertical line indicating no difference (for test of 
difference); and vertical lines indicating adjusted equivalence limits (for test of equivalence). For outcome types 1, 
3 and 5, the null hypothesis of no difference cannot be rejected: for outcomes 2, 4, 6 and 7, the genetically 
modified crop is different from its conventional counterpart. Regarding interpretation of equivalence, four 
categories (i) to (iv) are identified: in category (i), the null hypothesis of non-equivalence is rejected in favour 
of equivalence; in categories (ii), (iii) and (iv), non-equivalence cannot be rejected.
  
A. Regarding test of difference, each outcome from the graph shall be categorised as follows and the respective 
appropriate conclusion shall be drawn.  
(i) Outcome types 1, 3 and 5: the confidence interval bar overlaps with the line of no-difference. The null 
hypothesis of no difference cannot be rejected and the appropriate conclusion is that there is insufficient 
evidence that the genetically modified crop and its conventional counterpart differ.  
(ii) Outcome types 2, 4, 6 and 7: the confidence interval bar does not overlap with the line of no-difference. 
The null hypothesis of no difference must be rejected and the appropriate conclusion is that the 
genetically modified crop is significantly different from its conventional counterpart.  
B. Regarding test of equivalence, each outcome from the graph shall be categorised as follows, and the 
respective appropriate conclusion shall be drawn.  
(i) Outcome types 1 and 2 (category (i), Figure 1): both confidence limits lie between the adjusted equiv ­
alence limits and the null hypothesis of non-equivalence is rejected. The appropriate conclusion is that 
the genetically modified crop is equivalent to the set of non-genetically modified reference varieties.  
(ii) Outcome types 3 and 4 (category (ii), Figure 1): the mean of the genetically modified crop lies between 
the adjusted equivalence limits, but the confidence interval bar overlaps at least one of the adjusted 
equivalence limits on the graph. Non-equivalence cannot be rejected and the appropriate conclusion is 
that equivalence between the genetically modified crop and the set of non-genetically modified reference 
varieties is more likely to be the case than lack of equivalence.  
(iii) Outcome types 5 and 6 (category (iii), Figure 1): the mean of the genetically modified crop lies outside 
the adjusted equivalence limits, but the confidence interval bar overlaps with at least one of the adjusted 
equivalence limits. Non-equivalence cannot be rejected and the appropriate conclusion is that lack of 
equivalence between the genetically modified crop and the set of non-genetically modified reference 
varieties is more likely to be the case than equivalence.EN L 157/28 Official Journal of the European Union 8.6.2013(iv) Outcome type 7 (category (iv), Figure 1): both confidence limits lie outside the adjusted equivalence 
limits. The appropriate conclusion is that there is lack of equivalence between the genetically modified 
crop and the set of non-genetically modified reference varieties.  
In the case of significant difference and/or lack of equivalence for any particular endpoint, further statistical 
analysis shall be carried out to assess whether there are interactions between any of the test materials and site, 
possibly using a simple standard ANOVA approach. Whatever approach is adopted, details shall be given, for 
each endpoint analysed, listing: (a) the assumptions underlying the analysis, and, when appropriate: (b) 
degrees of freedom; (c) the estimated residual variation for each source of variation, and variance components; 
(d) any other relevant statistics. These additional analyses are intended to aid the interpretation of any 
significant differences found and to study potential interactions between test materials and other factors.  
More detailed guidance for the application of the requirements of this Section is available in the EFSA 
opinion on ‘Statistical considerations for the safety evaluation of GMOs’ (  1 ). 
1.3.3.  Selection of material and compounds for analysis  
Analysis of the composition of plant material is crucial when comparing the genetically modified food and feed 
with its conventional counterpart. The material to be used for the comparative assessment shall be selected while 
taking into account the uses of the genetically modified plant and the nature of the genetic modification. In the 
case of herbicide tolerant genetically modified plants, three test materials shall be used: the genetically modified 
plant exposed to the intended herbicide; the conventional counterpart treated with conventional herbicide 
management regimes; and the genetically modified plant treated with the same conventional herbicide 
management regimes. Unless duly justified, analysis shall be carried out on the raw agricultural commodity, 
as this usually represents the main point of entry of the material into the food and feed production and 
processing chain. Additional analysis of processed products (such as food and feed, food ingredients, feed 
materials, food and feed additives or food flavourings) shall be conducted, where appropriate and on a case- 
by-case basis (see also Section 1.3.6). The sampling, analysis and preparation of the tested material shall be 
carried out according to appropriate quality standards.  
1.3.4.  Comparative analysis of composition  
In addition to the analysis on the level of the newly expressed proteins (see Section 1.2.2.3), the compositional 
analysis shall be carried out on an appropriate range of compounds. In each case, the applicant shall provide at 
least analysis on proximates (including moisture and total ash), key macro- and micro-nutrients, anti-nutritional 
compounds, natural toxins, and already identified allergens, as well as other secondary plant metabolites char ­
acteristic for specific crop plant species, as referred to in the Organisation for Economic Cooperation and 
Development (OECD) consensus documents on compositional considerations for new plant varieties (OECD 
consensus documents) (  2 ). The vitamins and minerals selected for analysis shall be those which are present at 
levels which are nutritionally significant and/or which make nutritionally significant contributions to the diet at 
the levels at which the plant is consumed. The specific analyses required shall depend on the plant species 
examined, but shall include a detailed assessment appropriate to the intended effect of the genetic modification, 
the considered nutritional value and use of the plant. The applicant shall pay particular attention to key nutrients 
such as proteins, carbohydrates, lipids/fats, fibre, vitamins and minerals. For example, a fatty acid profile shall be 
included for oil-rich plants (main individual saturated, mono-unsaturated and poly-unsaturated fatty acids) and an 
amino acid profile (individual protein amino acids and main non-protein amino acids) for plants used as an 
important protein source. Analysis of plant cell wall components are also required for the vegetative parts of 
plants used for feed purposes.  
The applicant shall also provide an analysis on key toxins inherently present in the recipient plant which may 
adversely affect human/animal health depending on their toxic potency and levels. The concentrations of such 
compounds shall be assessed according to plant species and the proposed use of the food and feed product. 
Similarly, anti-nutritional compounds, such as digestive enzyme inhibitors, and already identified allergens shall 
be studied.  
The characteristics of the introduced trait may trigger further analysis of specific compounds including meta ­
bolites of potentially modified metabolic pathways. The applicant shall consider when appropriate, the inclusion 
of compounds other than the key nutrients, key toxins, anti-nutrients and allergens identified by the OECD 
consensus documents and justify the selection of these compounds.EN 8.6.2013 Official Journal of the European Union L 157/29

( 2 ) http://www.oecd.org/document/15/0,3746,en_2649_34385_46726799_1_1_1_1,00.html1.3.5.  Comparative analysis of agronomic and phenotypic characteristics  
The applicant shall provide a comparison between the genetically modified plant and its conventional 
counterpart. This comparison shall enable the applicant to identify unintended effects resulting from the 
genetic modification and shall address also plant biology and agronomic traits, including common breeding 
parameters (such as yield, plant morphology, flowering time, day degrees to maturity, duration of pollen viability, 
response to plant pathogens and insect pests, sensitivity to abiotic stress). The protocols of these field trials shall 
follow the specifications set out in Section 1.3.2.  
Where transformation events are stacked by conventional crossing, there may also be changes to agronomic and 
phenotypic characteristics. Possible differences in phenotypic characteristics and agronomic properties of stacked 
transformation events shall be assessed in field trials. Where appropriate, the applicant shall provide additional 
information on agronomic traits of the stacked transformation events from additional field trials.  
1.3.6.  Effects of processing  
The applicant shall assess whether or not the processing and/or preserving technologies applied are likely to 
modify the characteristics of genetically modified end products compared with their respective conventional 
counterpart. The applicant shall provide a description of the different processing technologies in sufficient detail, 
paying special attention to the steps which may lead to significant changes in the product content, quality or 
purity.  
Genetic modification can target metabolic pathways resulting in changes in the concentration of non-protein 
substances or in new metabolites (such as in nutritionally enhanced foods). Processed products may be assessed 
together with the assessment of the genetically modified plant for the safety of the genetic modification, or a 
processed product may be assessed separately. The applicant shall provide the scientific rationale for the risk 
assessment of these products. On a case-by-case basis, the submission of additional experimental data shall be 
considered by the applicant.  
When appropriate, depending on the product, information shall be necessary on the composition, level of 
undesirable substances, nutritional value and metabolism, as well as on the intended use.  
When appropriate, depending on the nature of the newly expressed protein(s), it shall be necessary to assess the 
extent to which the processing steps lead to the concentration or to the elimination, denaturation and/or 
degradation of these protein(s) in the final product.  
1.3.7.  Conclusion  
The conclusion of the comparative analysis shall clearly state:  
(a) whether agronomic and phenotypic characteristics of the genetically modified plant are, except for the 
introduced trait(s), different to the characteristics of its conventional counterpart and/or equivalent to the 
reference varieties, taking into account natural variation;  
(b) whether compositional characteristics of the genetically modified food and feed are, taking into account 
natural variation, different to the characteristics of its conventional counterpart and/or equivalent to the 
reference varieties, except for the introduced trait(s);  
(c) characteristics for which the genetically modified plant or the genetically modified food and feed are different 
to the characteristics of its conventional counterpart and/or not equivalent to the reference varieties taking 
into account natural variation, which need further investigation;  
(d) whether, in the case of transformation events stacked by conventional crossing, there are indications of 
interactions between the combined transformation events.  
1.4.  Toxicology  
The toxicological impact of any changes on the whole genetically modified food/feed resulting from the genetic 
modification such as the introduction of new genes, gene silencing or over-expression of an endogenous gene 
shall be assessed.  
Toxicological assessment shall be performed in order to:  
(a) demonstrate that the intended effect(s) of the genetic modification has no adverse effects on human and 
animal health;EN L 157/30 Official Journal of the European Union 8.6.2013(b) demonstrate that unintended effect(s) of the genetic modification(s) identified or assumed to have occurred 
based on the preceding comparative molecular, compositional or phenotypic analyses, have no adverse 
effects on human and animal health;  
(c) identify potential adverse effects of new constituents and determine their highest dose level that does not 
result in adverse effects. From data obtained from an appropriate animal study, an acceptable daily intake 
(ADI) of single compounds by humans may be derived by using uncertainty or safety factors that take into 
account differences between test animal species and humans, and inter-individual variations among humans;  
(d) identify potential adverse effects on the whole genetically modified food/feed or address remaining uncer ­
tainties through the performance of 90-day feeding studies.  
The applicant shall consider the nature of toxicological testing to be conducted on new constituents and whole 
genetically modified food/feed based on the outcome of the molecular and comparative analysis referred to in 
Sections 1.2 and 1.3, namely the differences identified between the genetically modified product and its 
conventional counterpart, including intended as well as unintended changes. The applicant shall also assess 
the results of the performed toxicological tests to consider the need to conduct additional testing on new 
constituents or on whole genetically modified food/feed as set out in Sections 1.4.4.2 and 1.4.4.3.  
The applicant shall take into account the presence of: newly expressed proteins, the potential presence of other 
new constituents and/or possible changes in the level of natural constituents beyond normal variation. The 
specific information requirements and testing strategies are set out in Sections 1.4.1 to 1.4.4.  
As regards applications of which the scope include or is restricted to genetically modified food and feed 
produced from genetically modified plants, toxicological studies with the processed products shall be provided 
except if the applicant provides a risk assessment of the genetically modified plant (or relevant parts of it) 
demonstrating its safety and there are no indications that the processed genetically modified food and feed would 
be any different from their respective conventional counterpart. The applicant shall provide adequate justification 
in this regard.  
Toxicology studies designed to evaluate risks to human and/or animal health shall complement each other. Most 
studies required for the assessment of the safety of the genetically modified food are also valid for the assessment 
of genetically modified feed.  
Besides the exposure of consumers and animals through intake of food and feed, any adverse effect(s) on 
individuals that could be due to their exposure to genetically modified food and feed material as part of their 
professional activities, for example, farming, seed processing, shall be reported by the applicant. Appropriate 
studies shall be performed to further characterise these indications of potential adverse effects.  
The applicant shall use internationally agreed protocols and test methods for toxicity testing (see Tables 1 and 2 
of Section 1.7). Adaptations of these protocols or use of any methods that differ from such protocols shall be 
justified in the application.  
1.4.1.  Testing of newly expressed proteins  
The applicant shall provide an evaluation of all newly expressed proteins. The studies required to investigate the 
potential toxicity of a newly expressed protein shall be selected on a case-by-case basis, depending on the 
knowledge available with respect to the protein’s source, function or activity and history of human or animal 
consumption. As regards proteins expressed in the genetically modified plant, in the case where the history of 
safe use for consumption as food and/or feed of both the plant and the newly expressed proteins is duly 
documented, specific toxicity testing as provided for in this Section shall not be required. In such case, the 
applicant shall provide the necessary information regarding the history of safe use of the proteins.  
Where specific testing is required, the tested protein shall be equivalent to the newly expressed protein as it is 
expressed in the genetically modified plant. If, due to the lack of sufficient amount of test materials from the 
plant, a protein produced by micro-organisms is used, the structural, biochemical and functional equivalence of 
this microbial substitute to the newly expressed plant protein shall be demonstrated. In particular, comparisons 
of the molecular weight, amino acid sequence, post-translational modification, immunological reactivity and, in 
the case of enzymes, the enzymatic activity are needed to provide evidence for the equivalence. In case of 
differences between the plant expressed protein and its microbial substitute, the significance of these differences 
for the safety studies shall be evaluated.EN 8.6.2013 Official Journal of the European Union L 157/31To demonstrate the safety of newly expressed proteins, the applicant shall provide:  
(a) A molecular and biochemical characterisation of the newly expressed protein, including determination of the 
primary structure, molecular weight (for example using mass spectrometry), studies on post-translational 
modifications and a description of its function. In the case of newly expressed enzymes, information on the 
enzyme activities including the temperature and pH range for optimum activity, substrate specificity, and 
possible reaction products shall also be provided. The potential interaction with other plant constituents shall 
also be evaluated.  
(b) An up-to-date search for homology to proteins known to cause adverse effects, such as toxic proteins. A 
search for homology to proteins exerting a normal metabolic or structural function may also contribute 
valuable information. The database(s) and the methodology used to carry out the search shall be specified.  
(c) A description of the stability of the protein under relevant processing and storage conditions and the 
expected treatment of the food and feed. The influences of temperature and pH changes shall be 
examined and potential modification(s) of the proteins (such as denaturation) and/or production of stable 
protein fragments generated through such treatments shall be characterised.  
(d) Data concerning the resistance of the newly expressed protein to proteolytic enzymes (such as pepsin), such 
as by  in vitro  investigations using appropriate and standardised tests. Stable breakdown products shall be 
characterised and evaluated with regard to the potential to cause adverse health effects linked to their 
biological activity.  
(e) A repeated-dose 28-day oral toxicity study with the newly expressed protein in rodents. When appropriate 
depending on the outcome of the 28-day toxicity study, further targeted investigations shall be provided, 
including an analysis of immunotoxicity.  
Acute toxicity testing of the newly expressed proteins of genetically modified plants is of little additional value 
for the risk assessment of the repeated human and animal consumption of genetically modified food and feed 
and shall not be provided as part of the studies performed under this point.  
The applicant shall perform studies with combined administration of proteins when the genetic modification 
results in the expression of two or more proteins in the genetically modified plant and when, based on scientific 
knowledge, a possibility of synergistic or antagonistic interactions of safety concerns is identified.  
1.4.2.  Testing of new constituents other than proteins  
The applicant shall provide a risk assessment of identified new constituents other than proteins. This shall 
include, on a case-by-case basis, an evaluation of their toxic potency and of the need of toxicological testing 
as well as a determination of their concentration in the genetically modified food and feed. To establish the safety 
of new constituents having no history of safe use for consumption in food and feed, the applicant shall provide 
information analogous to that described in the ‘Guidance for submissions for food additive evaluations by the 
EFSA Panel on Food Additives and Nutrient Sources added to Food’ of 16 August 2012 (  1 ) and Commission 
Regulation (EC) No 429/2008 of 25 April 2008 on detailed rules for the implementation of Regulation (EC) 
No 1831/2003 as regards the preparation and the presentation of applications and the assessment and the 
authorisation of feed additives (  2 ). This shall include the submission of information on a core set of studies such 
as on metabolism/toxicokinetics, subchronic toxicity, genotoxicity, chronic toxicity, carcinogenicity and repro ­
duction and developmental toxicity, accompanied by any other appropriate type of study. For specific guidelines 
for animal tests, see Table 1 of Section 1.7 of this Annex. Genotoxicity test protocols are provided for in Table 2 
of Section 1.7 of this Annex.  
1.4.3.  Information on altered levels of food and feed constituents  
This Section shall apply only in the case where the intended or unintended effect of the genetic modification 
would result in an alteration of the levels of food and feed constituents beyond the natural variation.EN L 157/32 Official Journal of the European Union 8.6.2013  
( 1 ) http://www.efsa.europa.eu/en/efsajournal/pub/2760.htm  
( 2 ) OJ L 133, 22.5.2008, p. 1.To demonstrate the safety of the altered levels of food and feed constituents such as macro- and micro-nutrients, 
anti-nutrients, and natural toxins as well as other secondary plant metabolites, the applicant shall submit a 
detailed risk assessment based on the knowledge of the physiological function and/or toxic properties of these 
constituents.  
The result of that risk assessment shall determine if, and to what extent, the applicant shall provide additional 
toxicological tests to the 90-day feeding study in rodents with whole genetically modified food/feed on selected 
food and feed constituents.  
1.4.4.  Testing of the whole genetically modified food and feed  
The applicant shall primarily base its risk assessment of the genetically modified food and feed on molecular 
characterisation, comparative agronomic, phenotypic and comprehensive compositional analysis, and the toxi ­
cological evaluation of the identified intended and unintended effects, including a 90-day feeding study in 
rodents with whole genetically modified food/feed as specified in Section 1.4.4.1. Under the circumstances set 
out in points 1.4.4.2 and 1.4.4.3 of this Section, additional specific toxicological studies with the whole 
genetically modified food and feed shall be carried out.  
1.4.4.1. 90-day feeding study in rodents with whole genetically modified food/feed  
The applicant shall include a 90-day feeding study with whole food and feed in rodents for the assessment of 
food and feed containing, consisting of or produced from genetically modified plants with a single trans ­
formation event or with stacked transformation events which are not obtained by conventional crossing of 
genetically modified plants containing a single transformation event.  
In the case of stacked transformation events obtained by conventional crossing of genetically modified plants 
containing one or several transformation event(s), a 90-day feeding study with whole food and feed in rodents 
shall be included for each of the genetically modified plant with a single transformation event which was used. 
An additional 90-day feeding study with whole food and feed in rodents with the genetically modified plant with 
the stacked transformation events shall be included where indications of potential adverse effects are identified 
during the assessment of: (i) the stability of the inserts; (ii) the expression of the inserts; and (iii) the potential 
synergistic or antagonistic effects resulting from the combination of the transformation events.  
The design of the toxicity study with genetically modified food and feed should be performed according to the 
‘subchronic oral toxicity test repeated-dose 90-day oral toxicity study in rodents’ (see Table 1) following an 
adapted protocol. In principle a minimum of two test doses and a negative control shall be used. The highest 
dose shall be the maximum achievable without causing nutritional imbalance; the lowest dose shall contain the 
tested food and/or feed in an amount always above the anticipated human/target animal intake level. The 
genetically modified food and feed analysed should be relevant to the product to be consumed. In the case 
of herbicide tolerant genetically modified plants, the tested material should come from the genetically modified 
plant exposed to the intended herbicide. Whenever possible, information on natural variation of test parameters 
shall be derived from historical background data rather than from the inclusion of reference varieties, consisting 
of commercially available food and feed derived from non-GM plants with a history of safe use, in the experi ­
ments. The statistical analysis shall focus on the detection of possible differences between the test material and its 
control. A power analysis to estimate a sample size capable of detecting a pre-specified biologically relevant effect 
size with a specified power and significance level should be used. More detailed guidance for performing this 
study is provided in the EFSA Guidance on conducting repeated-dose 90-day oral toxicity study in rodents on 
whole food/feed (  1 ). 
1.4.4.2. Animal studies with respect to reproductive and developmental toxicity testing  
When information required in Sections 1.4.1, 1.4.2 and 1.4.3 on the genetically modified food and feed suggest 
the potential for reproductive, developmental or chronic toxicity or in case of indications of adverse effects from 
the 90-day feeding study in rodents (such as functional and/or histological modifications of nervous, endocrine, 
reproductive or immunological tissues/organs), appropriate testing shall be performed. Protocols for reproductive, 
developmental and chronic toxicity testing (see Table 1 of Section 1.7) may be adapted for the purposes of 
testing the whole genetically modified food and feed.  
Given that the 90-day feeding study in rodents is only designed to detect effects on adult reproductive organ 
weights and histopathology and that it does not detect other effects on reproduction or development, testing of 
the whole food and feed beyond a 90-day rodent feeding study shall be conducted where hazards in this respect 
have been identified.EN 8.6.2013 Official Journal of the European Union L 157/33  
( 1 ) EFSA Journal 2011; 9(12):2438.1.4.4.3. Other animal studies to examine the safety and the characteristics of genetically modified food and feed (see also 
Sections 1.6.1 and 1.6.2)  
Feeding studies with target animal species shall be submitted when indications of adverse effects are drawn from 
information required in Sections 1.4.1, 1.4.2 and 1.4.3 on the genetically modified food and feed or from the 
outcome of the 90-day feeding study in rodents. Their focus shall be on the safety of new constituents (newly 
expressed proteins and other new constituents), on the identification and characterisation of unintended effects, 
and on the nutritional impact of any intentional, substantial, compositional modifications of the genetically 
modified plant (see also Section 1.6).  
Studies of that type shall be limited to plant materials suitable for inclusion in their diets and which can be 
nutritionally matched to a suitable control diet.  
1.4.4.4. Interpretation of relevance of animal studies  
Relevant effects observed in the animal trials shall be evaluated in order to identify potential consequences for 
the health of humans and animals and to assess their relevance for the safety of the genetically modified food 
and feed. This evaluation may be supported by additional information and considerations. Attention should be 
paid to the fact that certain effects may be specific for the test animal, but not for humans due to interspecies 
differences.  
The applicant shall, in particular, consider dose-response relationships in parameters that have been changed 
(that is to say, commensurate increases in changes at increased doses) since they provide a strong indication for 
an effect of the tested compound. When a difference is noted only at the highest dose applied, other factors shall 
be considered to determine whether there is a relationship with treatment. Information on the background 
variability in a given parameter may be obtained by the applicant from data from other animals of the same 
species/strain tested in the same or other experiments, or from internationally harmonised databases.  
In tests where animals of both genders are used, changes occurring in animals of one gender only may still be 
relevant indicators of an effect, depending on the parameter being changed and the mechanism by which the 
change may have been caused. For example, animals of one gender may be more or even specifically prone to 
changes caused by a given constituent than animals of the other gender, such as in the case of endocrine effects.  
The applicant shall also identify possible inter-relationships between observed changes in single parameters which 
may strengthen the indication that an effect has occurred. For example, liver damage, which may be observed in 
the liver itself as a change in histopathology, gross pathology, and organ weights, may also be evident from the 
changed levels of certain liver-derived compounds, such as enzymes or bilirubin in serum.  
With regard to the potential cause for an observed effect, the likelihood of causality shall be taken into account, 
not only for the test compound, but also for other factors that may have also influenced the outcomes (such as 
body weight decrease due to reduced intake of less palatable diet). Supportive data for a hypothesis of causality 
between the test compound and effects in test animals may include, for example, predictive data for plausible 
effects from  in vitro  and  in silico  experiments and dose-response relationships observed in the animal test.  
1.4.5.  Conclusion of the toxicological assessment  
The conclusion of the toxicological assessment shall indicate whether:  
(a) potential adverse effects identified in other parts of the safety assessment have been confirmed or discarded;  
(b) the available information on the newly expressed protein(s) and other new constituents resulting from the 
genetic modification gives indications of potential adverse effects in particular, whether and at which dose 
levels adverse effects were identified in specific studies;  
(c) the information on natural constituents of which the levels are different from those in its conventional 
counterpart provides indications of potential adverse effects, in particular, whether and at which dose levels 
adverse effects were identified in specific studies;  
(d) adverse effects have been identified from the studies made on the whole genetically modified food and feed 
and at which dose levels.  
The applicant shall evaluate the result of the toxicological assessment in the light of anticipated intake of the 
genetically modified food and feed (see Section 2).EN L 157/34 Official Journal of the European Union 8.6.20131.5.  Allergenicity  
Food allergy is an adverse reaction to food and represents an important public health problem. Food allergy is 
different from toxic reactions and intolerance. Allergy is a pathological deviation of the immune response to a 
particular substance, which affects only some individuals where a combined effect of variations in the 
environment and genetic predisposition has resulted in allergic sensitisation.  
In allergic individuals, sometimes minute amounts of a food that is well tolerated by the vast majority of the 
population can cause serious symptoms and death. It is not the allergen per se, but the allergic person’s 
abnormal reaction to the allergen that causes the adverse health effect.  
Food allergy can be caused by various immune mechanisms. However, IgE-mediated food allergy represents the 
main form of food allergy, that causes the most severe reactions and the only form causing life-threatening 
reactions. This IgE-mediated food allergy has been the focus in the risk assessment of allergenicity of GMOs. 
Importantly, food allergy consists of two separate phases: first  sensitisation  where no symptoms occur while the 
capacity of the immune system to react increases dramatically, and later  elicitation (provocation)  with clinical 
manifestations.  
When ingested, the allergen(s), that is to say, the sensitising food or food constituent is to some extent degraded 
by digestive enzymes, absorbed by the gut mucosa (small amounts even by the oral mucosa), processed in 
specialised cells of the immune system and then presented to the reactive immune cells that produce an immune 
response. Sensitisation can also occur if the food allergen comes into contact with the skin or is inhaled.  
The majority of the constituents that are responsible for allergenicity of foods, as well as of pollens, are proteins. 
Some protein breakdown products, that is to say, peptide fragments, may conserve part of the allergenicity of the 
native protein and thus can also be considered as allergens.  
The specific allergy risk of GMOs is associated with: (i) exposure to newly expressed protein(s) that can be 
present in edible parts of the plants or in the pollen; this point is related to the biological source of the 
transgene; and (ii) alterations to the allergenicity of the whole plant and its products, for example, due to 
over-expression of natural endogenous allergens as an unintended effect of the genetic modification; this 
point is related to the biology of the recipient plant itself.  
More detailed guidance for the application of the requirements of this Section is available in the EFSA scientific 
opinion on the assessment of allergenicity of GM plants and micro-organisms and derived food and feed adopted 
on 30 June 2010 (  1 ). 
1.5.1.  Assessment of allergenicity of the newly expressed protein  
Allergenicity is not an intrinsic, fully predictable property of a given protein but is a biological activity requiring 
an interaction with individuals with a pre-disposed genetic background. Allergenicity therefore depends upon the 
genetic diversity and variability in atopic humans. Frequency, severity and specificity of allergic reactions also 
depend upon geographic and environmental factors. Given this lack of complete predictability, it is necessary to 
consider several aspects in the assessment of allergenicity to obtain a cumulative body of evidence which 
minimises any uncertainty with regard to the protein(s) in question.  
When studying the structural characteristics and the biological and physicochemical properties of a newly 
expressed protein, it is essential that the tested protein is equivalent with respect to structure and activity to 
the newly expressed protein in the genetically modified plant. Studies carried out using purified target proteins 
prepared by expression in organisms such as  Escherichia coli  shall be acceptable provided that the properties of the 
microbial substitute protein are identical to those of the protein expressed in the plant, thus taking into account 
all post-translational modifications that specifically occur in the plant.  
The applicant shall verify whether the source of the transgene is allergenic. When the introduced genetic material 
is obtained from wheat, rye, barley, oats or related cereal grains, the applicant shall also assess the newly 
expressed proteins for a possible role in the elicitation of gluten-sensitive enteropathy or other enteropathies 
which are not IgE-mediated. Where transformation events have been stacked, the applicant shall provide an 
assessment of any potential for increased allergenicity to humans and animals on a case-by-case approach. These 
potential effects may arise from additive, synergistic or antagonistic effects of the gene products.EN 8.6.2013 Official Journal of the European Union L 157/35  
( 1 ) EFSA Journal 2010; 8(7):1700.The applicant shall follow an integrated, case-by-case approach, that is to say, a weight-of-evidence approach, in 
the assessment of possible allergenicity of newly expressed proteins. This approach shall include:  
(a) Amino acid sequence homology comparison between the newly expressed protein and known allergens  
In every case, a search for sequence homologies and/or structural similarities between the expressed protein 
and known allergens shall be performed to identify potential IgE cross-reactivity between the newly expressed 
protein and known allergens. The applicant shall ensure that the quality and the comprehensiveness of the 
databases are state of the art. The alignment-based criterion involving 35 % sequence identity to a known 
allergen over a window of at least 80 amino acids is considered a minimal requirement. All sequence 
alignment parameters used in the analysis shall be provided including calculation of percent identity 
(PID). The calculation of PID shall be performed on a window of 80 amino acids with gaps so that 
inserted gaps are treated as mismatches. In some cases, for assessing short peptidic fragments such as 
ORFs, a search for sequences of contiguous identical or chemically similar amino acid residue can be 
conducted. However, this search shall not be carried out routinely for the identification of potential linear 
IgE binding epitopes because of its poor sensitivity or specificity.  
(b) Specific serum screening  
When there is an indication of sequence homology or structure similarities, an important procedure for 
assessing the potential that exposure to the newly expressed proteins might elicit an allergic reaction in 
individuals already sensitised to cross-reactive proteins, is based on  in vitro  tests that measure the capacity of 
specific IgE from serum of allergic patients to bind the test protein(s). There is inter-individual variability in 
the specificity and affinity of the human IgE response. In particular, the specificity of the IgE antibodies to the 
different allergens present in a given food/source and/or to the different epitopes present on a given protein 
may vary amongst allergic individuals. In order to optimise the sensitivity of the test, individual sera from 
well-characterised allergic individuals shall be used. The applicant shall perform specific serum screening in 
the following cases:  
(i) the source of the introduced gene is considered allergenic, even if no sequence homology of the newly 
expressed protein to a known allergen is demonstrated; or  
(ii) the source is not known to be allergenic, but there are indications of a relationship between the newly 
expressed protein and a known allergen, based on sequence homology or structure similarity.  
Specific serum screening shall be undertaken with individual sera from individuals with a proven and well- 
characterised allergy to the source or to the potentially cross-reacting allergen using relevant immuno ­
chemical tests. IgE-binding assays (such as Radio or Enzyme Allergosorbent Assay (RAST or EAST), 
Enzyme Linked Immunosorbent Assay (ELISA) and electrophoresis followed by immunoblotting with 
specific IgE-containing sera) are adequate methods.  
(c) Pepsin resistance and  in vitro  digestibility tests  
Stability to digestion by proteolytic enzymes has long been considered a characteristic of allergenic proteins. 
Although it has been established that no absolute correlation exists, resistance of proteins to pepsin digestion 
is an additional criterion to be considered in the weight-of-evidence approach for the assessment of aller ­
genicity. The pepsin resistance test is generally performed under quite standardised conditions, at low pH 
values and high pepsin:protein ratios. It is recognised that the pepsin resistance test does not reflect the 
physiological conditions of the digestion. The digestibility of the newly expressed proteins in specific 
segments of the population, such as infants and individuals with impaired digestive functions, may be 
assessed using  in vitro  digestibility tests using different conditions. Also, since the protein encoded by the 
newly introduced genes will be present in the product as a complex matrix, the impact of the possible 
interaction between the protein and other components of the matrix, as well as the effects of the processing, 
shall be taken into account in additional  in vitro  digestibility tests. Depending on the outcome of the  in vitro  
digestibility test, a comparison of the intact, the heat-denatured and the pepsin-digested proteins for IgE 
binding shall be assessed since an altered digestibility may impact on the allergenicity of the newly expressed 
protein.  
(d) Additional tests  
Although additional tests including  in vitro  cell based assays or  in vivo  tests on animal models have not been 
validated to date for regulatory purposes, they may provide useful additional information, for example, on 
the potential of the newly expressed protein for  de novo  sensitisation.EN L 157/36 Official Journal of the European Union 8.6.20131.5.2.  Assessment of allergenicity of the genetically modified food or feed  
When the recipient plant is known to be allergenic, the applicant shall assess any potential change in the 
allergenicity of the genetically modified food or feed by comparison of the allergen repertoire with that of its 
conventional counterpart. The potential over-expression of natural endogenous allergen(s) in the genetically 
modified plant shall, in particular, be investigated.  
The applicant shall follow a case-by-case approach depending on the available information on the allergenic 
potential of the recipient plant. It is generally performed by analytical methodologies such as proteomics in 
association with the use of allergic human sera as probes. Sera from clinically well-characterised allergic indi ­
viduals that are the reference material for IgE binding studies may be available in limited number and quantity. In 
order to minimise the use of human sera, preliminary important information on the likelihood of an unintended 
alteration of the overall allergenicity of the genetically modified plant can be obtained by using sera of animals 
experimentally sensitised in well-defined conditions and by including relevant identified endogenous allergens in 
the comparative compositional analysis.  
In addition, the applicant shall provide, where available, information on the prevalence of allergy in persons 
working with, coming into contact with or in the vicinity of genetically modified plant cultivation.  
1.5.3.  Adjuvanticity  
Adjuvants are substances that, when co-administered with an antigen, increase the immune response to the 
antigen and therefore might increase as well the allergic response. In cases when known functional aspects of the 
newly expressed protein or structural similarity to known strong adjuvants may indicate possible adjuvant 
activity, the applicant shall assess the possible role of these proteins as adjuvants. As for allergens, interactions 
with other constituents of the food matrix and/or processing may alter the structure and bioavailability of an 
adjuvant and thus modify its biological activity.  
1.5.4.  Conclusion of the allergenicity assessment  
The conclusion of the allergenicity assessment shall indicate:  
(a) whether the novel protein(s) is likely to be allergenic;  
(b) whether the genetically modified food or feed is likely to be more allergenic than its conventional 
counterpart.  
When there is a likelihood of increased allergenicity due to the genetic modification, the genetically modified 
food or feed shall be further characterised in the light of its anticipated intake (see Section 2). The applicant shall 
propose appropriate conditions for placing on the market (such as post-market monitoring and labelling).  
1.6. Nutritional assessment  
1.6.1.  Objectives of the nutritional assessment  
The applicant shall provide a nutritional evaluation to demonstrate that:  
(a) the introduction of the genetically modified food and feed into the market is not nutritionally disadvan ­
tageous to humans and animals, respectively. This evaluation shall include the relevance for the nutrition of 
newly expressed proteins, other new constituents, and changes in the levels of food and feed constituents, as 
well as potential alterations in the total diet of the consumer or the animal;  
(b) unintended effects of the genetic modification that were identified or that may be assumed to have occurred 
based on the preceding molecular, compositional or phenotypic analyses, in accordance with Sections 1.2 
and 1.3, have not adversely affected the nutritional value of the genetically modified food and feed.  
For stacked transformation events combined by conventional crossing, an assessment of the potential changes in 
nutritional value that might arise from synergistic or antagonistic effects of the gene products including 
compositional changes shall be provided by the applicant. This may be particularly relevant where the 
combined expression of the newly introduced genes has unexpected effects on biochemical pathways.EN 8.6.2013 Official Journal of the European Union L 157/371.6.2.  Points to consider for the nutritional assessment of genetically modified food and feed  
The nutritional assessment of genetically modified food and feed shall consider:  
(a) the composition of the genetically modified food and feed with regard to the levels of nutrients and anti- 
nutrients (see compositional studies as described in Section 1.3);  
(b) the bioavailability and biological efficacy of nutrients in the food and feed taking into account the potential 
influences of transport, storage and expected treatment of the food and feed;  
(c) the anticipated dietary intake of the food and feed (see Section 2) and resulting nutritional impact.  
When the comparative analysis has identified compositional characteristics of the genetically modified food and 
feed that are different from its conventional counterpart and/or not equivalent to the characteristics of the 
reference varieties, their nutritional relevance shall be assessed on the basis of current scientific knowledge. If 
that assessment does conclude to the nutritional equivalence between the genetically modified food and feed and 
its conventional counterpart, no further studies shall be carried out. By contrast if, on the basis of the assessment 
of the information obtained from the comparative analysis, it is not possible to conclude on the nutritional 
equivalence, further nutritional studies shall be carried out. Comparative growth studies shall be conducted with 
young rapidly growing animal species (such as broiler chicks as animal model for non-ruminants; lambs for 
ruminants; or other rapidly growing species).  
1.6.3.  Nutritional studies of genetically modified food  
The applicant shall determine the necessity and design of nutritional studies on the basis of the introduced 
trait(s), the outcome of the comparative analysis, and of the 90-day feeding study, where available. Supple ­
mentary information regarding the nutritional value may be obtained from comparative growth performance 
studies conducted with other animal species, such as broiler chickens, addressing the nutritional assessment of 
genetically modified feed. When nutritional studies are conducted, the control diet(s) shall include the conven ­
tional counterpart and where appropriate additional comparator(s). In the case of herbicide tolerant genetically 
modified plants, the tested material should come from the genetically modified plant exposed to the intended 
herbicide.  
Genetically modified foods modified to provide additional health benefits to the consumer as compared to 
conventional foods, may benefit specific populations or subpopulations while others may be at risk from the 
same food. In cases where an altered bioavailability needs to be established and may raise concern for subpopu ­
lation(s), the level of the nutrient in the food shall be determined, taking into account all the different forms of 
the compound. The methods to test for bioavailability shall be selected on a case-by-case basis depending on the 
nutrient or other constituent, the food containing these constituents, as well as the health, nutritional status and 
dietary practices of the specific population(s) anticipated to consume the food.  
1.6.4.  Nutritional studies of genetically modified feed  
The applicant shall determine the necessity and design of further nutritional studies on the basis of the 
introduced trait(s), the outcome of the comparative analysis, and the 90-day feeding study, where available. 
Supplementary information regarding the nutritional value may be obtained from comparative growth 
performance studies conducted with other animal species, such as broiler chickens, addressing the nutritional 
assessment of genetically modified feed. When nutritional studies are conducted, the control diet(s) shall include 
the conventional counterpart and where appropriate additional comparator(s).  
In the case of genetically modified feed with improved nutritional characteristics, feeding studies with target 
animal of food producing species shall be conducted to assess the impact on the feed. In the case of genetically 
modified plants modified for improved content and bioavailability of nutrients, studies with target food 
producing animal species shall be conducted to determine the bioavailability of individual nutrients in the 
genetically modified plant compared to its conventional counterpart. In the case of genetically modified 
plants specifically modified with traits to enhance animal performance through increased nutrient density 
(such as increased oil content) or an enhanced level of a specific nutrient (such as an essential amino acid or 
a vitamin), an appropriate control diet using its conventional counterpart shall be formulated by supplementing 
it with the specific nutrient to the extent of the change effected in the genetically modified plant. Regarding co- 
products (such as oilseeds meals), from which the ingredient targeted by the genetic modification has been 
extracted, these may be compared with co-products produced from the conventional counterpart.EN L 157/38 Official Journal of the European Union 8.6.2013Target animal feeding studies shall span either the growing and/or finishing period to slaughter for chickens, 
pigs, and cattle for fattening or a major part of a lactation cycle for dairy cows, or laying cycle for laying hens or 
quails. For feedstuffs intended only for aquaculture, growth studies with aquatic species such as carp, catfish, 
salmonidae or typical herbivores shall be chosen.  
When appropriate, tests with various experimental designs shall be provided to demonstrate that the nutritionally 
improved genetically modified plant fulfils the expected nutritional value. The exact experimental design and 
statistical approaches of feeding experiments in food producing animals to test the nutritional value of genetically 
modified feed, modified for enhanced nutritional characteristics, shall depend on the targeted animal species, type 
of plant trait(s) studied and the size of the expected effect. The experimental diets shall be formulated in such a 
way that the key measured endpoints are responsive to a difference in the quantity and/or availability of the 
nutrient in question. Endpoint measurements shall vary with the target species used in the study, but shall 
include feed intake, body weight, animal performance and bioavailability of nutrients.  
More detailed guidance for the application of the requirements of this Section is available in the Report of the 
EFSA GMO Panel Working Group on Animal Feeding Trials (  1 ). 
1.6.5.  Conclusion of the nutritional assessment  
The conclusion of the nutritional assessment of genetically modified food and feed shall indicate whether the 
genetically modified food and feed is nutritionally equivalent to its conventional counterpart, taking natural 
variations into account.  
The applicant shall evaluate the result of the nutritional assessment in the light of anticipated intake of the 
genetically modified food and feed (see Section 2).  
1.7.  Standardised guidelines for toxicity tests  
The applicant shall use for toxicity testing internationally agreed guidelines and test methods described by 
Commission Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation 
(EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Auth ­
orisation and Restriction of Chemicals (REACH) (  2 ) (see Tables 1 and 2). A non-exhaustive list of validated 
test methods which, where necessary, shall be used in a possibly adapted form for GMO toxicological testing 
is provided in Tables 1 and 2.  
The performance of test methods depends on the type of genetically modified food and feed, type of the genetic 
modification and resulting intended and unintended alterations, intended use and exposure/intake, and the 
available knowledge. Some of the tests were developed for the assessment of risks at the workplace (see 
Sections 1.4 and 1.5).

2. EXPOSURE ASSESSMENT — ANTICIPATED INTAKE/EXTENT OF USE  
An estimate of the expected intake shall be an essential element in the risk assessment of genetically modified 
food and feed and shall also be required for the nutritional evaluation. Information shall be provided by the 
applicant on the intended function, the dietary role, and the expected level of use of the genetically modified 
food and feed in the EU. In addition, the expected range of concentrations of newly produced proteins or 
existing plant proteins deliberately modified in the genetically modified food(s) and feed(s) to be placed on the 
market shall be provided.  
On the basis of representative consumption data for products obtained from the respective conventional plants, 
the applicant shall estimate the anticipated average and maximum intake of the genetically modified food and 
feed. Probabilistic methods may be used to determine ranges of plausible values rather than single values or point 
estimates. The applicant shall identify and consider particular groups of the EU population with an expected 
higher exposure and shall consider this higher exposure within the risk assessment. Any assumptions made in 
the exposure assessment shall be described. Recent developments in methodologies and appropriate consumption 
data shall be used. Data on import and production quantities may provide additional information for the intake 
assessment.EN L 157/40 Official Journal of the European Union 8.6.2013The applicant shall determine by appropriate methods the concentrations of the newly expressed proteins, other 
new constituents and endogenous food and feed constituents, of which the levels have been altered as a result of 
the genetic modification (for example, due to changes in metabolic pathways) in those parts of the genetically 
modified plant intended for food or feed use. Expected intake of these constituents shall be estimated taking into 
account the influences of processing, storage and expected treatment of the food and feed in question, for 
example, potential accumulation or reduction. In cases where the genetic modification has resulted in an altered 
level of a natural constituent, or if a new constituent occurs naturally in other food and feed products, the 
anticipated change in total intake of this constituent shall be assessed considering realistic as well as worst case 
intake scenarios.  
The applicant shall provide information on known or anticipated human/animal intake of analogous genetically 
modified food and feed and on other routes of exposure to the respective new and natural constituents, 
including amount, frequency and other factors influencing exposure.  
3. RISK CHARACTERISATION  
3.1. Introduction  
The applicant shall base its risk characterisation of genetically modified plants and foods and feed on data from 
hazard identification, hazard characterisation, and on exposure/intake data. The applicant shall ensure that the 
risk characterisation is comprehensive by considering all the available evidence from several analysis including 
molecular analysis, phenotypic, agronomical and compositional analysis, toxicity and allergenicity testing. The 
applicant shall consider indications resulting from the risk characterisation that may require specific activities for 
post-market monitoring of genetically modified food and feed.  
In performing its risk characterisation, the applicant shall demonstrate that the hazard identification and hazard 
characterisation are complete. The applicant shall discuss the quality of existing data and information. The 
discussion shall clearly indicate how this body of information has been taken into account in the determination 
of the final risk characterisation.  
The applicant shall provide estimations of the uncertainties associated to each test as well as to the different 
stages of the risk assessment. The applicant shall quantify them to the possible extent. A distinction shall be 
made between uncertainties that reflect natural variations in biological parameters (including variations in 
susceptibility in populations), and variation amongst different species’ responses.  
Depending on the issue to be addressed and the available data, the applicant shall perform a qualitative and, 
where possible, quantitative risk characterisation. The conditions for the estimated risk, and associated uncer ­
tainties, shall be as precise as possible.  
3.2. Issues to be considered for risk characterisation  
When appropriate and depending on the type of genetic modification, the applicant shall carry out a risk 
assessment of genetically modified plants in an integrative manner in accordance with Section 3.1. This risk 
assessment shall be performed on a case-by-case basis depending on the modified plant and the type of genetic 
modification, the cultivation practices of the genetically modified plant and uses of the genetically modified food 
and feed. The applicant shall take into account the different issues considered in hazard identification and hazard 
characterisation and exposure steps. The outcomes of these issues shall be considered by the applicant together 
in the risk characterisation step. The list of issues provided in this Section shall not be exhaustive.  
3.2.1.  Molecular characterisation  
Evaluation of the characteristics and previous use of the donor and the recipient plant shall be a key element to 
identify the need for specific analyses, such as the occurrence of specific toxins, or allergens in the unmodified 
recipient plant which may be unintentionally increased as result of the genetic modification.  
Transformation protocols, molecular characterisation strategies and the specificity and sensitivity of the methods 
used shall be discussed by the applicant in relation to the intentional and possibly unintentional insertion and 
expression of gene sequences.  
Where sequence analysis has identified a potential hazard, the applicant shall demonstrate how approaches like 
bioinformatic analysis, compositional/agronomical analysis and possibly animal feeding trials with the whole 
genetically modified food and feed contribute to the safety assessment. The value of the results obtained shall be 
evaluated in the light of the available knowledge on the structure and function of genomic databases of the crop 
species in question or related species.EN 8.6.2013 Official Journal of the European Union L 157/41In cases of GM plants containing stacked transformation events, the additional risks possibly arising from the 
combined effects of the stacked genes shall be evaluated.  
3.2.2.  Comparative analysis  
The first goal of the comparative analysis is to identify possible differences between the GM plant and its 
conventional counterpart and, where appropriate, additional comparators. The second goal of the comparative 
analysis is to identify possible lack of equivalences between the GM plant and its reference varieties. These 
differences and/or lack of equivalences should be assessed with respect to their possible impact on food and feed 
safety and nutritional properties, taking into account natural variation. The estimated risk and associated uncer ­
tainties should be as precise as possible and taken into account.  
The applicant shall demonstrate that the comparative analysis between the genetically modified plant and its 
conventional counterpart with respect to agronomic, morphological and compositional characteristics has been 
carried out in accordance with the requirements of this Regulation. The selection of the conventional counterpart 
and, where appropriate, additional comparators shall be justified.  
3.2.3.  Food and feed safety in relation to intake  
The applicant shall evaluate the data generated to estimate possible short-term and long-term risks to human or 
animal health associated with the consumption of genetically modified food or feed with respect to the 
expression of new proteins/metabolites, as well as significantly altered levels of original plant proteins/metabolites 
in genetically modified foods/feed. This evaluation shall include a thorough analysis of the relevance and 
limitations of each test as well as of the whole information.  
The applicant shall consider the range of levels observed for the compounds known to occur in the conventional 
counterpart and in reference varieties. This variability may be caused by differences that are genotype-dependent, 
environmentally dependent, or caused by genotype x environment interactions. In addition, the range of levels 
observed in a broad spectrum of food and feed representative for the human and animal diet may be taken into 
account given that it reflects the levels of the specific compound to which consumers may be exposed.  
If single constituents and/or whole genetically modified food and feed are found to induce adverse effects in 
specific studies, information on dose response relationships, threshold levels, delayed onset of adverse effects, 
risks for certain groups in the population, and use of uncertainty factors in extrapolation of animal data to 
humans shall be submitted.  
The applicant shall consider data on the characteristics of the new compounds present in the genetically 
modified plant including potential biological effects in humans and animals. If the compounds have known 
adverse health effects and maximum levels for the presence of these compounds in the plant or its products were 
laid down in specific legislation, these maximum levels shall be taken into account. Otherwise, reference values 
for acceptable or tolerable levels of intake, such as the acceptable daily intake (ADI) or tolerable upper intake 
level (UL), shall be considered in relation to the anticipated intake. In cases where the compound has been safely 
consumed in food, the intake levels of consumers from a conventional diet shall be considered as safe.  
The applicant shall evaluate the information on the effects of processing on the new compounds. Potential 
accumulation/depletion in food and feed products entering the human or animal diet shall be considered. The 
applicant shall also evaluate the relevance of differences resulting from chemical reactions known to occur under 
processing conditions.  
In cases where more complex genetic modifications are produced, for example, via transfer of multiple genes in a 
single construct, retransformation of pre-existing genetically modified lines, and stacking of transformation 
events through conventional breeding of genetically modified parents, the applicant shall discuss strategies for 
the assessment of any risk(s) associated with possible interactions between the newly expressed proteins, new 
metabolites and original plant constituents. The assessment shall take into account all available information 
including the mode of action of the newly expressed proteins, the molecular and compositional/agronomical 
characteristics of the genetically modified plant, and the outcome of animal toxicity studies and feeding trials.  
The applicant shall evaluate data obtained to assess the allergenic potential of newly expressed proteins in 
genetically modified plants with respect to introduction of new allergenic proteins into the food and feed 
plants, a possible provocation of allergic reactions of susceptible individuals, as well as information to demon ­
strate that the genetic modification does not cause unintended changes in the characteristics and/or levels of 
expression of endogenous allergenic proteins in the genetically modified food. In particular, the choice of the test 
models shall be justified with respect to specificity, predictability and validation status.EN L 157/42 Official Journal of the European Union 8.6.2013With respect to intake estimations of genetically modified foods, the applicant shall evaluate the applied 
methodologies with respect to uncertainties associated with the prediction of long-term intake. Specific 
attention shall be paid to those genetically modified plants which are aimed at modifying nutritional char ­
acteristics of the food and feed. For those genetically modified products, the requirement for post-market 
monitoring shall be discussed as a mechanism for determining actual changes to overall dietary intake 
patterns of the genetically modified food, to what extent this has occurred and whether or not the product 
induces known (side) effects or unexpected side effects. If the performance of post-market monitoring is deemed 
necessary, the reliability, sensitivity and specificity of the proposed methods shall be provided.  
3.3.  The result of risk characterisation  
In accordance with the requirements of Articles 4 and 16 of Regulation (EC) No 1829/2003, the applicant shall 
ensure that the final risk characterisation clearly demonstrates that:  
(a) the genetically modified food and feed has no adverse effects on human and animal health;  
(b) the genetically modified food does not differ from the food which it is intended to replace to such an extent 
that its normal consumption would be nutritionally disadvantageous for the consumer;  
(c) the genetically modified food does not mislead the consumer;  
(d) the genetically modified feed does not harm or mislead the consumer by impairing the distinctive features of 
the animal products;  
(e) the genetically modified feed does not differ from the feed which it is intended to replace to such an extent 
that its normal consumption would be nutritionally disadvantageous for animals or humans.  
The applicant shall clearly indicate what assumptions have been made during the risk assessment in order to 
predict the probability of occurrence and severity of adverse effect(s) in a given population, and the nature and 
magnitude of uncertainties associated with establishing these risks.  
The applicant shall also include detailed information justifying the inclusion or not of a proposal for labelling in 
the application, in accordance with Article 13(2)(a), Article 13(3), Article 25(2)(c) and Article 25(3) of Regulation 
(EC) No 1829/2003.EN 8.6.2013 Official Journal of the European Union L 157/43ANNEX III

These data and results shall be presented, where possible and appropriate, by using the performance parameters 
as referred to under point 3.1.C.4. The applicant shall also provide a summary of the testing carried out and the 
main results as well as all the data including the outliers.  
B. The applicant shall ensure that the provided information demonstrates the robustness of the method for inter- 
laboratory transferability. For this purpose, the applicant shall provide the results of the testing of the method by 
at least one laboratory that is different from the laboratory which has developed the method.  
C. The applicant shall provide the following information about the method development and the method optimis ­
ation:  
1. primer pairs tested and probe, if appropriate, including a justification as to how and why the proposed primer 
pair has been selected;  
2. stability testing, which shall be established through the submission of experimental results from testing the 
method with different plant varieties;  
3. specificity, which shall be established through the submission of the full sequence of the insert(s) in a 
standardised electronic format, together with the base pairs of the host flanking sequences so as to enable 
the EURL to assess the specificity of the proposed method by running homology searches in a molecular 
database;  
4. precision, the relative repeatability standard deviation shall be less than or equal to 25 % related to mass 
fraction over the whole dynamic range of the method.  
D. The applicant shall, in addition to the information required under Sections A, B and C provide the following 
information regarding the testing:  
1. participating laboratories, time of the analysis and outline of the experimental design, including the details 
about the number of runs, samples, replicates, etc.;  
2. description of the laboratory samples (such as size, quality, date of sampling), positive and negative controls as 
well as certified reference material, plasmids and alike used;  
3. description of the approaches that have been used to analyse the test results and outliers;  
4. any particular points observed during the testing;  
5. references to relevant literature or technical provisions used in the testing.  
3.3. Samples of the food and feed and their control samples  
For the purpose of implementing Articles 5(3)(j) and 17(3)(j) of Regulation (EC) No 1829/2003, the applicant shall, 
together with the information required under Sections 1, 2 and 3 of this Annex, also provide samples of the food 
and feed and their control samples of a type and amount to be specified by the EURL for the specific application for 
authorisation.  
The information accompanying the control samples shall include information on the breeding of the plant which 
has been used for the production of the control samples and on the zygosity of the insert(s).  
The applicant may use the same raw material for the production of certified reference material and for the 
production of control samples.  
4. CERTIFIED REFERENCE MATERIAL  
The certified reference material shall be produced under ISO Guide 34 (General requirements for the competence of 
reference material producers) by a producer accredited to ISO Guide 34.EN L 157/46 Official Journal of the European Union 8.6.2013The applicant shall provide information as regards the place where the certified reference material can be accessed. 
This shall be accompanied by adequate information demonstrating that the availability of the certified reference 
material will be maintained throughout the period of validity of the authorisation. For verification and value 
assignment, a method that has been properly validated (see ISO/IEC 17025: General requirements for the 
competence of testing and calibration laboratories) shall be used.  
Uncertainties shall be estimated according to the ISO Guide to the Expression of Uncertainty in Measurement (GUM).  
The main characteristics of those internationally accepted technical provisions are the following:  
1. Genetically modified reference material containers:  
(a) genetically modified reference material container (such as bottles, vials, ampoules) shall be tight and contain 
not less than the stated amount of material;  
(b) the commutability of the genetically modified reference material must be assured;  
(c) packaging shall be appropriate to the purpose;  
(d) labelling shall be of good aspect and quality.  
2. Homogeneity testing:  
(a) samples shall have appropriate homogeneity;  
(b) between-bottle homogeneity shall be examined;  
(c) any possible between-bottle heterogeneity shall be accounted for in the overall estimated reference material 
uncertainty. This requirement shall apply even when no statistically significant between-bottle variation is 
present. In this case, the method variation or the actual calculated between-bottle variation, whichever is 
larger, shall be included in the overall uncertainty.  
3. Stability testing:  
(a) samples shall have appropriate stability;  
(b) stability shall be positively demonstrated by appropriate statistical extrapolation for the genetically modified 
reference material shelf-life to be within the stated uncertainty; the uncertainty related to this demonstration is 
part of the estimated reference material uncertainty. Assigned values are valid only for a limited time and shall 
be subject to a stability monitoring.  
4. Batch characterisation:  
1. The methods used for verification and for certification shall:  
(a) be applied under metrologically valid conditions;  
(b) have been properly technically validated before use;  
(c) have precision and trueness compatible with the target uncertainty.  
2. Each set of measurements shall:  
(a) be traceable to the stated references;  
(b) be accompanied by an uncertainty statement whenever possible.  
3. Participating laboratories shall:  
(a) have the required competence for the execution of the task;EN 8.6.2013 Official Journal of the European Union L 157/47(b) be able to achieve traceability to the required stated references;  
(c) be able to estimate their measurement uncertainty;  
(d) have in place a sufficient and appropriate quality assurance system.  
5. Final storage:  
1. To avoid degradation after sample production, all samples shall be stored under conditions designated for the 
final storage of the genetically modified certified reference material before measurements are started.  
2. Otherwise, they shall be transported from door to door keeping them at all times under such storage 
conditions for which it has been demonstrated that there is no influence on the assigned values.  
6. Establishment of a certificate for certified reference material:  
A certificate complemented by a certification report shall be established, containing all information relevant to 
and needed by the user.  
The certificate and report shall be made available when the genetically modified certified reference material is 
distributed.  
The information accompanying the certified reference material shall include information on the breeding of the 
plant which has been used for the production of the certified reference material and on the zygosity of the 
insert(s).  
The certified value of the GMO content shall be given in mass fraction and, where available, in copy number per 
haploid genome equivalent.  
Certified values (such as quantity of genetically modified material expressed in mass fraction) shall be traceable to 
stated references and be accompanied by an expanded uncertainty statement valid for the entire shelf-life of the 
genetically modified certified reference material.EN L 157/48 Official Journal of the European Union 8.6.2013
