Submission on Proposal P1055 Definitions of Gene Technology
Lay summary
INBI supports the effort to define gene technology in a way that captures all current andfuture techniques. However, the proposed preferred definition is inadequate. In addition, wenote that Australia has already defined some techniques as not gene technology despite theirpotential conformity to FSANZ's preferred definition.1 We are therefore concerned that any
definition is pro forma and without substance.
We do not agree that a priori exclusions based on hypothetical and voluntary evaluations of
biological characteristics of some New Breeding Techniques products are sufficient to ensure
safe and responsible use of gene technology.
We propose that this is an opportunity to adopt both a risk-relevant definition and a risk
assessment framework that is risk-relevant by moving away from a list of arbitrary andmutable technical terms based on named examples of gene technology and onto a criticalcontrol points framework. The goal should be a regulatory system that is no less safe rather
than not more complicated. With changes in technology FSANZ cannot expect that risk
assessment gets simpler.
Summary
The intention to re-define gene technology for legislative purposes is welcome. Genetechnology requires a definition that is responsible to the valid societal expectation that it
can be used responsibly because the potential for harm can be maintained at an acceptablelevel.
Unfortunately, the proposed definition is of a genre that will suffer the same premature aging
as the current definition. A new definition should describe the activities of gene technologythat relate to the risks it creates, not rely upon the assumption that underlying biologicalterminology has the same meaning to everyone. We submit that FSANZ should consider whatmakes gene technology a technology and look to regulate gene technology with lessons fromthe successful use of critical control points for other technologies. With the adoption of afuture-ready and scientifically-consistent definition we believe that it is possible to groupuses and products according to categories that are defined by the critical control points that
determine when and what risk assessment is needed.

1“techniques that use recombinant, synthesised or amplified nucleic acid to modify or create a genome”

We thank Food Standards Australia New Zealand for inviting responses to this proposal.
As we understand the proposal, FSANZ is seeking to revise the definitions of genetechnology in order to 1. improve regulatory clarity on what is and is not within scope, 2.
remain able to regulate already recognised techniques and adapt as techniques of genetic
engineering are described in novel new ways or when eventually fundamentally newtechniques may be invented, and to 3. organise products into risk groups that allow for casespecific, efficient and effective risk assessment. The Centre for Integrated Research in
Biosafety (INBI) supports these objectives.
FSANZ understandably wants to future-proof the legislation and regulations. To do so
requires describing the technology through the fundamental characteristics that define why itshould be regulated and how to control its potential to cause harm. Unfortunately, theanalysis provided in Proposal P1055 does not do this but instead continues to use a list of
examples in a semantic approach for grouping techniques of gene technology. P1055 persistsin the failing approach of using undefined words that keep on morphing in meaning, boththrough scientific advances and because some developers and researchers want to limit their
meanings to maximise deregulated space, which also minimises accountability for harm.2
To future-proof legislation and regulations requires a vision for scope that covers how
genetically modified organisms are presently made and how the technology is changing how
they can be made. Describing techniques of gene technology by their biochemistry, whether
it be the reactions that lead to the insertion of a ‘transgene’ and the reactions that lead togenome editing, provides little clarity for technology governance.
The difference in the scales at which different techniques and products can be used mattersfor governance.3 The characteristic of the technology that justifies social governance throughlegislation is that it can amplify the rate and magnitude of harm by increasing the ease ofuse, number of people using it, range of types of organisms and numbers of individuals it isused on, and the number of environments where it can be applied. Every technique of genetechnology invented does this relative to conventional breeding, which is scale-limited by therate of spontaneous genetic change that can be acted upon by breeders and the generation
time of the organisms that they breed.
Chemical and radiation mutagenesis changed the rate of genetic change. In vitro mutagenesis
using chemicals or oligonucleotides increased the efficiency of creating desired changes.
Transgenesis further increased the rate of genetic change as well as efficiency of creating
desired changes. The “New Breeding Techniques” accelerate change by also increasing
efficiency but also through easier access to the reagents and reducing dependence on highly
trained personnel and expensive facilities (Heinemann et al. 2021).

For example, see the tortured attempt by COGEM (COGEM 2010) to find a way to define recombinant andfailure to achieve any scientific basis. Similar arbitrary and inconsistent reasoning is used to define epigenes outof scope. Likewise, protein-nucleic acids (PNAs) and future chemicals derived from modified nucleic acids may
be arbitrarily defined as different from what the proposed regulations mean by nucleic acids.

The new dimensions of scale available to NBTs include among other things a new pipeline
for changing characteristics of organisms that are food, or are inseparable from our food. For
example, genome editing reagents can be applied as topical agents absorbed on contact, in thedigestive track or in lungs by inhalation. They can be used to create desired genetic changes
in real time over landscapes or product types, even in the grocery store (Heinemann 2019;
Heinemann and Walker 2019).
The model underlying P1055 is one where expensive laboratory facilities with highly trained
personnel are needed in order to create, identify, and then amplify a rare modified individual.
As a consequence, the developer secures a pure stock. Well before release into theenvironment or use in food, the characteristics of the organism are described.4,5 This is thehistory of all the products upon which FSANZ has based its analysis in P1055. Extrapolations
to future-proofed regulation cannot be made from that history. The potential exists for alltechniques of gene technology and associated new methodologies to increase the potential forany of them to cause harm if arbitrarily released from active regulatory oversight.
A technique can be defined out of scope but not as safe. We submit that FSANZ should focus
on the characteristics of technology that create risk and manage those characteristics with risk
assessment and other means, as appropriate. This would be a departure from the focus on
how techniques, biochemical reactions, genes, genomes and biological characteristics can be
described to sound more or less like something not made using gene technology.
1. Governance and legislative scope
1.1. What FSANZ refers to as a “legal definition for GM food based on old methods” isnot accurate.6 The techniques referred to as NBTs are neither new techniques nor are
they new to food produced using gene technology. When the legal definitions wereadopted, there had been for decades tools for guided or site-directed DNA
modifications, the feature all described NBTs have in common (Heinemann et al.
2021). Indeed even the term “gene editing” was used in a 1980 review ofcontemporary techniques of genetic engineering (Itakura and Riggs 1980). There are
documented cases of editing using oligonucleotides unassisted by nucleases (such as
Cas9, which is a new catalyst) in the late 1980s and early 1990s in both yeast andmice (Heinemann et al. 2021).
4

However, the difference between the current pipeline of making an organism in containment and assessing its
characteristics prior to release or use as food and in situ use of the NBTs is a critical control point that isrelevant to what categories products would fall into for risk assessment. Thus, not the NBT used but controls on
where it is used prior to evaluation would be the important regulatory trigger.
5
The techniques of genetic engineering have long been scale-limited by the need to use contained laboratories
to protect and find the rare individuals that have been altered by the techniques in vitro, which is partly becauseof the inefficient uptake of exogenous nucleic acids, even transfer from Agrobacterium tumefaciens, andproteinaceous mutagens such as double-stranded DNA nucleases (Heinemann et al. 2021). Thesemethodological constraints result in a development paradigm where individual GMOs are amplified incontainment and then in pure form are analysed for a pre-market risk assessment. Not all anticipatedapplications of NBTs are similarly constrained and therefore do not result in a single, pure GMO from which it
is possible to credibly assert similarity of biological and chemical characteristics (Heinemann and Walker2019).
6
From the FSANZ consultation documents. “New breeding techniques or NBTs are a diverse collection of newtechniques for genetic modification that have emerged over the last decade or more.”31.2. We acknowledge that routine use of site-directed tools in plants and livestock animal
species was limited prior to the development of, for example, ZFNs, TALENs and
CRISPR/Cas. However, oligonucleotide mutagenesis was available for use. This is
not to say that creating genetically modified organisms in these species using suchreagents was easy, and that perhaps is why the ‘transgene’ methods dominated foruse in agriculture over those decades. However, it is inaccurate to say that in general
NBTs are based on fundamentally new methodologies. Calling them new does notmake them new.
1.3. One NBT that might be new is the use of double-stranded RNA to cause temporary
or heritable changes in gene expression (usually gene silencing) or to cause
recombination with heritable RNA elements, such as found in fungi (Heinemann2019).7 However, it is a site-directed nucleic acid technique as are other NBTs.
1.4. Therefore, we agree with the proposal to “revise and expand the process-based
definition for ‘gene technology’ to capture all methods for genetic modification otherthan conventional breeding”. This should include both chemical and radiation
mutagenesis and gene silencing if for no other reason than in the latter technique thedouble-stranded RNA can recombine with heritable RNA elements in fungi and it
can in some organisms cause heritable changes (Heinemann 2019).
2. How to categorise for risk
2.1. In general we agree that:
2.1.1. NBTs may result in foods with biological and chemical characteristics similar
to those that arise from spontaneous processes in nature that are then amplified
under a supervised process such as conventional breeding, and that NBTs may
result in foods that do not have similar biological and chemical characteristics.
2.1.2. NBT foods can be regulated “in a manner that is commensurate with the risks
they pose.”6
2.2. We do not agree that similarities in biological and chemical characteristics are
sufficient to determine safety without a risk assessment. While some of thesechanges will not result in adverse effects, a compulsory pre-market risk assessment
helps to reduce the chances that those that could cause adverse effects will enter the
food system. Deregulation of any technology potentially grows its scale of use anddiversity of users. The more who use gene technology, the more likely an adverse
event or product will arise. Risk but not safety scales with deregulation.
2.3. Not all applications for approval of GM foods received by FSANZ and otherregulators around the world have either been accepted or progressed to a stage of
regulatory compliance. The pre-market risk assessment may be a - or the - reason
why there is no definitive proof of a harmful GM food approved by regulators so

7

We find it mildly curious that while this truly new technique with no history of safe use conforms to FSANZ’s
preferred new definition of gene technology – “techniques that use recombinant, synthesised or amplified
nucleic acid to modify or create a genome” – it is specifically defined by Australia as not gene technology.

4

far.8 In the following paragraphs we provide examples of how regulation constrains
the scalability of harm.
2.3.1. Two foods with the same biological and chemical characteristics can havedifferent potential to cause harm. This is due to the differential caused bysocial/legal conventions that determine what, if any, kind of intellectual property
rights they attract. For example, NBT products can be granted intellectual
property rights protections that are more powerful than products that have been
isolated by conventional breeding despite being judged to have the same
biological and chemical characteristics. The stronger the IPR, the greater the
likelihood the product will be favoured by the mega-concentrated foodproduction and distribution industries. Consequently, any undetected harm could
be more quickly and widely amplified and distributed by products made using
NBTs than those conventionally breed. They may also undergo different pre-saleprocessing resulting in different chemical reactions and further disconnecting
them from the history of safe use.
2.3.2. Without a risk assessment, the number of biological and chemical
characteristics that are different is likely to be underestimated because only
characteristics related to intended or anticipated changes will be examined. Even
if an unbiased screen were routinely used, the public cannot be assured that an‘apples and ~apples’ approach to comparator selection was used. For example,
FSANZ has previously used a characteristic of button mushrooms to argue theequivalence with a characteristic in a GM maize despite the many
characteristics, including consumption patterns and food preparation, that are
different between conventional mushrooms and maize.9
2.3.3. Deregulation may result in even more egregious examples of cherry picking
characteristics of different varieties, and sometimes very different species, forcomparison purposes.
2.3.4. Importantly, all comparisons lead to normative judgements, not absolutecertainty of safety. How similar is similar? How many characteristics have to be
similar for overall biological and chemical similarity? Different standards may
exist between regulators as well as between manufacturers. The US National
Academies warns us of the embedded uncertainty even in rigorous assessments.

For example: “In the first case, research was conducted on a soybean line genetically engineered to produce a
Brazil nut (Bertholletia excelsa) protein, which was a known allergen. Sera from patients allergic to Brazil nut
protein were available and tested positive for activity against the GE soybean protein. Because the segregationfrom the human food supply of GE soybean with that protein could not be guaranteed, the project was halted(Nordlee et al., 1996). The soybean variety was never commercialized” (NASEM 2016). Note that the original
publication reported that the gene for the protein had already been inserted also into “tobacco, oilseed rape
(Brassica napus), the legume Vicia narbonensis, and beans (Phaseolus vulgaris)” (Nordlee et al. 1996). “As aresult of this assessment, commercial interest in this transgenic soybean variety was abandoned. However, we
stress that such experiments in the hands of no[n] experts may pave the way to new mishaps” (emphasis added
to quote from Cantani 2006).

This uncertainty is not adequately addressed in proposals to exclude someproducts from regulatory oversight.
There are many reviews and official statements about the safety of foods from GE crops(for example, see Box 5-1)…With regard to the issue of uncertainty, it is useful to notethat many of the favorable institutional statements about safety of foods from GE crops inBox 5-1 contain caveats, for example: ‘no overt consequences,’ ‘no effects on humanhealth have been shown,’ ‘are not per se more risky,’ and ‘are not likely to present risks
for human health.’ Scientific research can answer many questions, but absolute safety ofeating specific foods and the safety of other human activities is uncertain. (NASEM 2016)
2.4. To regulate a technology proportional to risk requires knowing how the harm canscale. This knowledge may seem easier to obtain for food than for environmental risk
assessment, but that is not assured. For example, different home preparation
traditions including different mixtures of foods contribute to the complexity ofassessing risk. Recalling the quote above by the US NASEM which acknowledges
the uncertainties that characterise the science, “[p]roportionality can only be relevant
to what is reliably known and quantifiable (i.e. due to case-by-case basis); thepossible adverse effects of genome edited [NBT] plants are far from reliably
knowable, including risks through scaling and across time.”10
2.5. Nevertheless, provided that FSANZ were able to confirm that those using NBTs on
food have completed a credible examination of the product for unintended changes
and associated unintended biological characteristics, it is theoretically possible toplace some products into different categories with different assessment requirements.
2.5.1. Disappointingly, this theoretical possibility is already undermined by theindustry itself. An “argument in favor of equivalence testing is that the onus todo high-quality, well-replicated experiments with sufficient statistical power isplaced on to those who wish to demonstrate the safety of GMOs” (van der Voetet al. 2019), but it also incentivises cheating, or at least sloppiness. The mostrecent demonstration is that of Recombinetics’ cattle. Following the company’s
publicly expressed confidence in its approach to screening unintended changes it
was later found to have overlooked unintended transgene insertions. The
industry has not yet earned the trust society can expect of a regulator relying on
voluntary compliance.
The developer of hornless cattle has retracted its claims about precision and purity of the
genome modifications (Carlson et al., 2016; Van Eenennaam et al., 2019) after FDA
scientists found that they were not accurate (Norris et al., 2020). The company initiallysaid that: “We have all the scientific data that proves that there are no off target effects”(quoted in Regalado, 2020), but it overlooked, among other changes, about 4,000 new

6nucleotides inserted during the application of the new techniques, including antibiotic
resistance genes. (Heinemann et al. 2021)
2.5.2. Unfortunately, we also see little evidence from the history of FSANZ thatwithout legislative or political compulsion it will use its own discretion to
improve the reporting standards from manufacturers. For example, it does not
require the use of techniques that provide comprehensive identification of
unintended changes in its risk assessments despite this being a recommendationfrom both the research community (Agapito-Tenfen et al. 2018; Heinemann etal. 2011) and the US National Academies:
It is the change in the actual characteristics of the plant, intended and unintended, thatshould be assessed for risks. Recent developments in -omics technologies have madethorough assessments of those characteristics of plants attainable in the near future. Evenin their current state of development, the technologies could enable a tiered approach toregulatory testing in which any new variety shown to have no new intended traits withhealth or environmental concerns and no unintended alterations of concern in its
composition would be exempted from further testing (Figure S-3). The costs of -omics
methods are decreasing, but even current costs are low relative to the cost of othercomponents of regulatory assessments. (NASEM 2016)
2.6. For these and other reasons (set out below):
2.6.1. INBI does support (Option 3) a “revised and expanded process-based
definition for ‘gene technology’”. We do not support the definition that
FSANZ prefers.
2.6.2. INBI does not support “Product-based pre-market safety assessment
exclusions for certain foods” based on exclusion criteria focussed on foodcharacteristics alone. We do not believe that the proposed non-regulatory
approaches are a satisfactory way to mitigate risk.
2.6.3. We submit that the proposed product-based exclusions are actually processbased exclusions in disguise. FSANZ is proposing to deregulate processes that
result in products that have characteristics similar to other products that may
have been created using arbitrarily deregulated processes, for example chemical
and radiation mutagenesis or heritable double-stranded RNA treatments, andnever assessed for risk. The product-based exclusion is therefore likely to lead torisk creep.
2.6.4. INBI supports Option 3 with the deletion of the sentences “revise thedefinition for ‘food produced using gene technology’ to include specificproduct-based criteria for excluding certain foods from pre-market safetyassessment and approval as GM food. Foods not meeting all relevant exclusion
criteria would require an application to FSANZ.” Those sentences could be
replaced with “Foods produced by NBTs require an application to FSANZ.”

3. Product-based voluntary approaches are not future-proof
3.1. This quote from a submission to the European Commission on its consultation on
regulation of new techniques demonstrates precisely the same problem with
FSANZ’s framing of risk. “Several OECD countries including Canada, the US,
Japan, Australia, and Colombia are adopting similar, pragmatic approaches. At theirbase, they recognize that new genomic techniques are no riskier than conventional
breeding and therefore should be managed accordingly.”11
3.2. In contrast, the Norwegian Society of Rural Women frame the risk appropriately bysaying: “We are not against GMOs in general, but genetic engineering differs fromtraditional breeding and processing in both radicalism and pace.”12 This is similar toNobel Laurette Sydney Brenner’s framing when he said that (radicalism) “there is
now available a method which allows us to cross very large evolutionary barriers andto move genes between organisms which have never before had genetic contact” and(pace) the “essence is that we now have the tools to speed up biological change and if
this is carried out on a large enough scale then we can say that if anything can happen
it certainly will. In this field, unlike motor car driving, accidents are self-replicating
and could also be contagious” (Brenner 1974).
3.3. Conventional breeding is limited by the spontaneous mutation rate, generation timeof the organism, species, size of the organism, power of applicable intellectual
property rights instruments, and number of breeders. NBTs have far fewer
limitations. Their difference in radicalism and pace is, after all, why they have value
and concomitantly how they can cause harm.
3.4. The fundamental characteristic of technology is that it allows people to do things
faster and in a more concentrated way (Heinemann et al. 2021).3 The fundamental
source of harm from technology is that people can do certain things faster and in amore concentrated way. Deregulation increases the number of people using thetechniques and lowers the expertise required to use them. Therefore, the reason toregulate technology is to control the potential for harm from its use by people. A
focus on products of a technological process is a way to control harm from atechnology but it is not the only way.
3.4.1. For example, chemical and radiation mutagenesis is a technology because it
allows changes to be made to genes and organisms faster than what occurs by
conventional breeding, the latter relying on the spontaneous mutation rate. The
use of chemical and radiation mutagenesis is considered a gene technology in

Australia defined chemical and radiation mutagenesis as not a gene technology(DoH 2018a).13
3.4.2. The decision to define chemical and radiation mutagenesis as not a genetechnology but transgenesis and NBTs as gene technology is scientificallyinconsistent. It exposes a lack of understanding of the underlying purpose ofregulation to control adverse effects of technology. The impact of doing so is,however, limited. This is not because chemical and radiation mutagenesis has no
scalable potential to cause harm. It is because the reagents of chemical andradiation mutagenesis are controlled by other legislative instruments that restrict
access and require that they be used by highly trained personnel in containment
facilities, and require registration of the products (Heinemann et al. 2021).
P1055 does not create these other controls for NBTs.
3.5. We do not believe that it is valid to compare what can be done using technology tothe history of spontaneous DNA changes that have occurred in the genomes oforganisms people eat over evolutionary time. First, both people and food have beenchanging over evolutionary time. Mutations that arose spontaneously in nature
resulted in foods that may have been better, worse, or irrelevant to us. Our genetic
ancestors may also have evolved (genetically or through learning) to overcome theeffects of mutations that lessened the value of these organisms to us as food. Second,
foods produced using gene technology do not have evolutionary time lines. Our
highly concentrated food industries can inadvertently distribute something harmful tolarge numbers of people in a short time unlike at any other period in human
evolution. Consequently we disagree with the conclusion that “Conventional food istherefore a suitable benchmark for assessing the risks from NBT foods” or othergene technology techniques.
3.6. FSANZ knows how little product it takes to contaminate the world food supply with
unapproved and therefore potentially unsafe food, which is why it no longer issues
split decisions with the Office of the Gene Technology Regulator. On the global
scale, production of Starlink and BT10 maize, LL rice, and Roundup Ready wheat
were miniscule. In some cases, only a few hectares. Yet these products spreadworldwide and a few, decades later, are still appearing. Even the scale of small scaletinkerers becomes relevant to food safety. The worrying message from adoption of
P1055 is that tinkering is safe because the process is safe.
3.7. P1055 is not addressing non-genetic risks to food safety. Risk is also a function of
the concentration of the food production and distribution sector and its capacity to
13

Why Australia took this decision is not apparent to us. Proposal P1055 is a way to rectify this inconsistency
provided that it could be made inclusive of specifically deregulated gene technology techniques. If regulatory
expediency were the reason it was defined out of legislation, clearly that was not the only option because as
proposed in P1055, organisms made using chemical or radiation mutagenesis could be exempted from further
risk assessment rather than use arbitrary exclusions. We note that New Zealand has defined some chemicalmutagenesis as and some as not creating a GMO for purposes of risk assessment.

9use monopoly power intellectual property rights – that conventional breeding has not
had – to ramp-up harm at unprecedented scale. If conventional foods were a suitablebenchmark for assessing the genetic risks from NBT foods (which we do not accept),then FSANZ should consider that infectious disease (see Brenner’s quote, above) is
the other appropriate benchmark for assessing the modern risks from NBT foods.
3.8. Deregulation is de facto scale change in the mutation rate of both food andinseparable organisms that occur in food.14 The scale is increased in magnitude by
the number of people who use the tools and the number of organisms exposed. That
number can and will increase with products that allow such work in situ, throughtopical applications (Heinemann and Walker 2019). In the proposed product-based
and voluntary compliance framework proposed, only the intended food organisms
will be evaluated. How many off-target effects of the inseparable fungi inadvertently
sprayed with a ZFN or a Cas9-guide mixture intended as a herbicide on a “farm” of
10,000 hectares is FSANZ suggesting that society accept as safe without review?
3.9. We offer a potential solution to this problem by suggesting that it is not the techniqueof gene technology used that is determinative of the risk category. In the first
instance it is how the technique is used. We present that idea below but with thiscaution. The intention of FSANZ may be to reduce the use and expense of risk
assessment, but that would only be possible if the technology had not changed.
Obviously, it has at least in its ability to scale. Therefore, as the US NASEM
observed, risk assessment may need to change for safety to stay the same or improve.
“[f]uture GE crops…could greatly expand the use of agricultural biotechnology in thedevelopment of biofuels, forestry restoration, and industrial bioprocessing and thus
potentially lead to new risk-assessment and risk-management issues.” (NASEM 2016).
3.10.
Exclusion criteria are not supported by us. However it may be possible togroup uses into categories defined by relevant critical control points. Two examples
follow.
3.10.1. A risk assessment category might apply to all development done incontainment and all development that was from chemical and radiation
mutagenesis. This category could include all genetically engineered livestock
and plants of the kind that already have been approved by FSANZ, and could
apply to all future development using NBTs this way. For practical purposes, themembers of this category could be split into sub-categories for risk assessment.
In category 1A are the products of chemical and radiation mutagenesis that
require no further assessment provided that they were also listed with theInternational Atomic Energy Agency. This is because of other regulatory
restrictions on the use of chemical and radiation mutagens. In category 1B are allother products that will be evaluated according to the requirements of law and to
evolving standards of international guidance, such as Codex Alimentarius.
Proposals for this should be developed and consulted by FSANZ, but we also14

10encourage adoption of -omics based techniques for hazard identification asrecommended by the US NASEM.
3.10.2. A different risk assessment category might apply to any outdoor use of genetechnology and to release of Living (genetically) Modified Organisms.
Therefore, it may require thorough and new approaches to risk assessment andrisk management which should be developed and consulted by FSANZ.
However, it may also be possible to further sub-categorise members of this set
with case-specific assessments.
4. Definition criteria
4.1. The USDA definition preferred by FSANZ is inadequate to cover some current andalso future/pending techniques or actually new technologies.
4.2. The length of the definition in Australian (and New Zealand) legislation as listed inTable 2 of Supporting Document 3 illustrates the failures of its semantic approach todefining gene technology. Australia has already inconsistently defined sometechniques as not being gene technology despite them potentially conforming to the
USDA definition. Thus, we do not believe that the USDA or any other definition
based on other undefined/contested terms either will be sufficient or future-proof.
4.3. Instead, we advocate a heuristic definition that describes the properties of genetechnology. We submit that a new draft definition should be developed for further
consultation.
4.3.1. The definition should not exclude technology that increases the scale ofpotential harm with use.15
4.3.2. The definition should not be limited to nucleic acids. The use of any agent
intended to accelerate the overall or specific mutation rate and rate of creating
new phenotypes should be included.16 It is unclear why only one kind of agent(nucleic acids) for introducing genetic change is identified by FSANZ as
relevant when the biological and other risks are the genes that are changed.
4.3.3. The definition should not be limited to the persistence of the causative agent,nucleic acid or otherwise, in a product for the product to be within scope.

15

Advancements in nucleic acid delivery also allow proteins to be taken up in situ, including proteins that may
have mutagenic activities (Heinemann and Walker 2019). In this continuum resides what is commonly
understood to be genetic engineering, but does not necessary require the “use of recombinant, synthesised oramplified nucleic acid to modify or create a genome” because of arbitrary definitions also used in practice forthe words “genome”, “recombinant”, “amplified” and “synthesise” as well as the ability to substitute other kindsof molecules for nucleic acids to achieve the end result. Spraying protein mutators such as ZFNs or TALENs in
a formulation that allows them to be taken into cells can have the same outcome as spraying small chemicalmutagens or radioactive material. The latter is prevented by other legislation because of potential to cause harm
(Heinemann et al. 2021). The same potential harm should be recognised for mutagens that are proteins or othernon-nucleic acid molecules.
16
Note that treatments to alter traits en masse by manipulating genes is a pathway of scalable harm for long
lived perennial plants and even fresh fruits and vegetables post-harvest, even if the organism does not reproduce(Heinemann 2019).

11

4.3.4. If the word genome is to be used, then it should be defined in a way that iscomprehensive for any molecular basis of inheritance of traits because
inheritance is a pathway to scalable harm. We should not, for example, bearguing in the future about whether or not making changes to replicating RNA
elements in the cytoplasm of fungi is genetic engineering because of semantic
disputes over whether or not they are part of the “genome”.
4.3.5. The definition should capture all technology that can result in the change of
biological or chemical characteristics, phenotypes/traits by intervention in thepathways and molecules that determine the biological or chemical,
phenotypes/traits of organisms, viruses and other replicating elements (e.g.,
plasmids, prions and epigenes). We should not, for example, be arguing in the
future about whether or not making life-long changes to gene expression in fruit
trees by application of double-stranded RNA is a gene technology.
