4Introduction 
The New Zealand Food Safety Authority (NZFSA) invites public comment on this discussion 
document which outlines proposals to amend the New Zealand (Maximum Residue Limits of 
Agricultural Compounds) Food Standards 2008.  
Maximum residue limits (MRLs) are the maximum legal limits for residues of agricultural 
compounds and veterinary medicines in food for sale in New Zealand.   
MRLs are primarily a tool for monitoring the us e of agricultural compounds in accordance with 
good agricultural practice (GAP).  GAP is not exp licitly defined or regulated, but is the generally 
accepted means for producing safe primary produc e in a particular location while taking account 
of climate, pests or diseases an d other environmental factors.   
MRLs are used to minimise risks to public health  by ensuring that chemical residues in food are 
as low as practicable, without compromising the ability of the chem ical to succes sfully do what 
is intended.  
Background 
MRLs are set out in the New Zealand (Maximum Residue Limits of Agricultural Compounds) Food Standards. The Standards are amended a number of times each year to reflect changes 
in the use of agricultural compounds in the production of food.  The current MRL Food 
Standards 2008 are on the NZFSA website at: 
http://www.nzfsa.govt.nz/policy-
law/legislation/food-standards/index.htm
NZFSA administers the MRL Standards, but the final decision on any changes to the Standards rests with the Minister for Food Safety.  Under section 11E of the Food Act, when amending or 
issuing the MRL Standards, the Minister must take into account the following: 
• the need to protect public health 
• the desirability of avoiding unnecessary restrictions on trade 
• the desirability of maintaining consistency between New Zealand's food standards and 
those applying internationally 
• New Zealand's obligations under any relevant international treaty, agreement, convention, 
or protocol, and, in particular, under the Australia-New Zealand Joint Food Standards 
Agreement 
• such other matters as the Minister considers appropriate.  Proposals to Amend (No. 2) the New Zealand (Maximum Residue Limits of Agricu ltural Compounds) Food Standards 2008 
  
5                                                     The proposed MRLs have been thoroughly assessed in accordance with international 
methodologies such as those utilised by the ex pert committees advising the Codex Alimentarius 
Commission (Codex).  Information on the technical assessment of each proposal is included in this document and covers the following:  
• rationale 
• chemical information 
• good agricultural practice (GAP) 
• residues information 
• dietary risk assessment 
• toxicological / public health assessment 
• international MRLs. 
Possible implications for public health are considered during the toxicological and dietary risk assessments, by comparing the es timated dietary intake with a Potential Daily Exposure (food) 
(PDEfood) or wher e there is no PDE
food, by comparing it with the Acceptable Daily Intake (ADI).  
PDE food and ADI are described below.   
A PDE food or Potential Daily Exposure (food), is a va lue determined by a toxicological evaluation 
by Environmental Risk Management Authority New Zealand (ERMA NZ) as part of its 
responsibilities u nder the Hazar dous Substances and New Organisms Act (the HSNO Act), 
which has some resp onsibility for managing public health.1  A PDE food gives the potential daily 
exposure a person may be subject to from a substance, via food.  NZFSA uses a PDE food, rather 
than the internationally-determined ADI, where a PDE food is available, due to the HSNO Act in 
New Zealand.  The ADI and PDE food are largely equivalent, as they are determined using the 
same set of toxicology data and in a very similar scientific process. 
An ADI or Acceptable Daily Intake is defined by the World Health Organization (WHO) as: “The daily intake which, during an entire lifetime, app ears to be without appreciable risk on the basis 
of all the known facts at the time”.  “Without  appreciable risk” has been further defined as: “the 
practical certainty that injury will not result  even after a lifetime of exposure”.  ADIs are 
established by the WHO and Food and Agricult ure Organization of the United Nations (FAO) 
joint expert committees, made up of toxicologists and residue specialists.  The ADI information 
from these joint committees also feeds into  Codex, which sets international MRLs. 
 
 
1The purpose of the HSNO Act 1996 is “to protect the environm ent, and the health and safety of people and communities, by 
preventing or managing the adverse effects of  hazardous substances and new organisms”.    Proposa ls to Amen d (No. 2)  the New  Zealand (Max imum Residue  Limits of A gricultural Compou nds) Food Stand ards 2008  
Summary of Proposed Amendment 
NZFSA ha s reviewe d the estimated dietary exposur e assessm ents for the a pplication s of the se 
proposals an d ha s determined th at th e residues associated with the proposed M RLs do not 
present any p ublic h ealth a nd safety co ncerns. 
New MRLs 
NZFSA propo ses to add th e followin g new MRL s to th e Standards:  
• Boscalid in g rapes (3m g/kg) and in po me fruits (0.05 mg/kg); 
• Cloma zone in  brassi ca veg etable s (0.01mg/kg) and in  carrots (0.02 mg/kg); 
• Cypro dinil in stone fruit (exc ept cherrie s) (0.02mg/ kg);  
• Emamectin b enzoate in av ocados (0.00 5mg/kg ); 
• Fenbe ndazole in mammali an fat (0.05m g/kg), ma mmalian ki dney (0.05mg/kg), mammalia n 
liver (0.5mg/ kg), mammali an musc le (0.05mg/k g); 
• Mandip ropamid in bulb oni ons (0.01m g/kg) a nd in g reen onio ns (0.2mg/kg ); 
• Monep antel i n sheep fat (7 mg/kg ), she ep liver (5mg/ kg), she ep ki dney (2mg/ kg) and in 
sheep mu scle (0.7mg/ kg); 
• 1-Naphthyla cetic in mand arins (Satsu ma and Encore ) (0.01 mg/kg); 
• Oxfenda zole i n mammalia n fat (0.05mg/kg), mammali an kidn ey (0.0 5mg/kg ), ma mmalian 
liver (0.5mg/ kg), mammali an musc le (0.05mg/k g); 
• Pyr aclostrobin in grap es (2mg/kg ). 
Next S teps 
Followi ng th e clo sing da te for submi ssions (5: 00pm on Wednesday 30th July 20 08), all  
submi ssions will be consi dered a nd analysed before a recommendation is made to the Minister  
for Food Sa fety, the Ho n Lianne Dalziel, w ho m akes the final deci sion on issuing a ny 
amend ment s to the Food Standards.   
If an amend ment is agree d upon, it will be signe d by the Minister for Foo d Safety and will co me 
into force 2 8 days after bei ng publi shed in the New Zealan d Ga zette.

It is propo sed that MRLs are set fo r boscalid when  used as a fungi cide for grapes and pome fruits.  It  
is pro posed that Sched ule One of the NZ (MRL) Food Standards 2008 be am ende d to incl ude the

Amendment Rationale  
The p roposed MRLs for b oscalid  represent th e registration in  New Zealan d of a new active i ngredient. 
The pro posed MRL s will manag e the new u se of b oscalid a s a fungi cide on p ome fruits an d grap es to

Boscalid i s proposed fo r use as a fun gicide for grapes.  Applicatio n may be th roughout p re-flowering to  
pre-harvest, at rate of 378 gai/ha with a withhol ding p eriod of 28 d ays.   
Boscalid i s proposed for use as a fungicide for pome fruit s.  Applicatio n may be up t o 2 time s 
throug hout early to mid growin g sea son at 7-10 day interval s , at 12.6gai/h a with a with holdi ng pe riod 
of: do not app ly after 90% petal fall.   
Residues Information 
Residue data for grape s suppo rts an  MRL of 3m g/kg at 28 days after the l ast treatment.  A n MRL of  
3mg/kg i s therefore pro posed to sup port GAP. 
 7 Proposa ls to Amen d (No. 2)  the New  Zealand (Max imum Residue  Limits of A gricultural Compou nds) Food Stand ards 2008  
Residue data  for pome fru its sup ports a limit of quantification M RL of 0.05m g/kg when treatment i s 
prior to 100%  petal fall.  An  MRL of 0.05 mg/kg is therefore p roposed to sup port GAP. 
Anim al Transfer:  Apple po mace, g rape poma ce and vineyard wast e may be fed to animals, h oweve r 
given the exp ected consumption level of boscalid in  these comm odities it would not be expected that 
residues woul d be dete ctable in animal p roduct co mmodities. 
Dietary  Risk Assessment 
 
 Acceptable Daily  Exposure (ADE) 0.04mg/kg b w/day 
ERMA NZ PDE (food ) 0.028mg/ kg bw/day 
The p otential daily expo sure via food (PDE (food))is used for di etary i ntake calculation whe re a v alue h as 
been set.  The potential da ily exposure via food (PDE (food)) is use d for dietary intake calculation whe re 
a value  has been  set. Th e PDE (food) is a valu e set by the Enviro nmental Risk Mana gement Authority  
(ERMA), and represents the proportion o f the acceptable d aily ex posure  to a substa nce via  the food  
route a s relevant to the New Zeal and p opulatio n.  T he method ology for cal culation of these values i s 
set out in the  Hazardou s Substan ces (Cla sses 6,  8, and 9 Controls) Regulati ons 2 001 which can b e 
found at: www.legi slation. govt.nz .  
The ch ronic d ietary exposu re to boscali d is estimated by the Nation al Estimated Dietary Intake (NE DI) 
calculatio n encompassing all re giste red uses of the chemi cal and food consumption data  based upon 
the 199 7 National Nutrition al Survey for adults and th e 1995 Natio nal Nutrition Survey of Au stralia, f or 
children. Th e NEDI cal culation is ma de in accordan ce with Guid elines fo r pre dicting dieta ry intake of  
pesti cide resi dues (revi sed) [Worl d Health Orga nizatio n, 1997]. 
The NEDI for boscalid is e quivalent to 9% of the PDE (food). It is therefo re con cluded that the ch ronic 
dietary expo sure is small a nd the risk is accepta ble. 
Toxicological / Public Health Ass essment   
It has been determi ned that the use of boscalid a s a fungici de for use on g rapes and pome fruits,  
according to the GAP spe cified above, is very unlik ely to pose an y health risks from con sumption of 
the harve sted commo dity.   
Other International MRLs 
To meet Ne w Zeala nd’s obligation s unde r the Ag reement on  the Applica tion of Sanitary an d

2 Proposal to set MRLs for Clomazone  
It is proposed that MRLs are set for Clomazone when used as a herbicide for brassica vegetables and 
carrot s. It is proposed tha t Schedule One of the NZ (M RL) Food Standa rds 200 8 be amend ed to  
include:

Amendment Rationale  
The proposed MRLs represent new use patte rns in New Zealan d for th e active ingredie nt clomazone.  
The propo sed MRL s will manag e the new u ses of clomazone as a he rbicide on bra ssica vegetable s

Residues Information 
Residue data for ve getabl e brassicas suppo rts a limi t of qu antifica tion M RL of 0.01mg/kg at 40  days 
after the last treatme nt.  An MRL of 0.01 mg/kg is therefore p roposed to sup port GAP. 
Residue data  for carrots support s an M RL of 0.02mg/kg at 90 days after the last treatme nt.  An  MRL of  
0.02mg/kg is therefo re pro posed to su pport GAP. 
 
 9 Proposa ls to Amen d (No. 2)  the New  Zealand (Max imum Residue  Limits of A gricultural Compou nds) Food Stand ards 2008  
Anim al Tran sfer:  Brassi ca vegetabl es are considered a primary animal feed;  however,  given  that no  
residues are expecte d in forage brassicas, resi dues will not b e expect ed to accum ulate in anima l 
products. No animal comm odity MRLs a re therefore p roposed at this time. 
Dietary  Risk Assessment 
 
 Acceptable Daily  Intake (ADI) 0.03mg/kg b w/day 
The p otential daily expo sure via food (PDE (food))is used for di etary i ntake calculation whe re a v alue h as 
been set.  An appro priate accepta ble daily inta ke (A DI) is u sed in the absen ce of a PDE (food). 
The ch ronic dietary expo sure to clom azone is es timated by the National E stimated Di etary Intake  
(NEDI) calculation e ncompassin g all registe red uses of the chemical  and food consum ption d ata 
based up on the 199 7 Nati onal Nutrition al Survey for adults a nd th e 1995 Natio nal Nut rition Survey of 
Australi a, for child ren. Th e NE DI ca lculation i s made in acco rdance with  Guideline s for predi cting 
dietary intake  of pesticid e resid ues (revi sed) [World Health Org anization, 1997]. 
The NE DI for cloma zone is equival ent to 0.8% of the ADI. It is therefo re concluded that the ch ronic 
dietary expo sure is small a nd the risk is accepta ble. 
Toxicological / Public Health Ass essment   
It has bee n determin ed th at the use of cloma zone as a he rbicide for use on brassica veg etable s and

Dietary  Risk Assessment 
Acceptable Daily  Intake (ADI) 0.007mg/ kg bw/day 
 
The p otential daily expo sure via food (PDE (food))is used for di etary i ntake calculation whe re a v alue h as 
been set.  An appro priate accepta ble daily inta ke (A DI) is u sed in the absen ce of a PDE (food). 
The chro nic dietary expo sure to oxfend azole is e stimated by the  National Est imated Dieta ry Intake  
(NEDI) calculation e ncompassin g all registe red uses of the chemical  and food consum ption d ata 
based up on the 199 7 Nati onal Nutrition al Survey for adults a nd th e 1995 Natio nal Nut rition Survey of 
Australi a, for child ren. Th e NE DI ca lculation i s made in acco rdance with  Guideline s for predi cting 
dietary intake  of pesticid e resid ues (revi sed) [World Health Org anization, 1997]. 
The cu rrent NEDI for oxfenda zole is equivalent to  0.5% of the  ADI, with accommo datio n of th e 
proposed M RLs the NE DI increa ses to 2.5% of t he ADI. It is therefo re con cluded that the ch ronic 
dietary expo sure is small a nd the risk is accepta ble. 
Toxicological / Public Health Ass essment   
It has been determi ned that the incre ase of the o xfendazole M RLs for mam malian fat, muscle and  
kidney to 0.0 5mg/kg  is very unlikely to  pose any health risks fro m consumption of the ani mal product

Amendment Rationale 
The p roposed MRL represe nts a new use patte rn in New Zealan d for the a ctive ingre dient 
pyracl ostrobin. The propo sed M RL will manag e the  new u ses of pyraclo strobin as a fun gicide on 
grapes to  the appli cation rates a nd withholdin g periods that a re approve d good agricultural practice 
(GAP) in New Zealand (see below).

Good Agric ultural Prac tice 
Pyraclo strobin is pro posed for use a s a fungicide for gra pes.  Applicatio n may be thro ugho ut pre -
floweri ng to p re-harve st, at rate of 192g ai/ha with a withholding p eriod of 28 day s.   
Residues Information 
Residue data for grapes suppo rts an  MRL of 2 mg/kg at 2 8 days after the  last treatment.  An M RL of 
2mg/kg i s therefore pro posed to sup port GAP. 
Anim al Transfer:  Grap e poma ce and vineyard wa ste may be f ed to animal s, however g iven the  
expecte d co nsum ption le vel of pyracl ostro bin in these co mmo dities it woul d not be exp ected tha t

Dietary  Risk Assessment 
Acceptable Daily  Intake (ADI) 0.03 mg/kg b w/day 
 
The p otential  daily expo sure via fo od (PDE (food)) is used for diet ary inta ke calculatio n whe re a valu e 
has b een set.  An approp riate accepta ble daily in take (ADI) i s used in the absen ce of a PDE (food). 
The chronic dietary exp osure to pyracl ostro bin is estimated by th e National  Estimated Dieta ry Inta ke 
(NEDI) calculation e ncompassin g all registe red uses of the chemical  and food consum ption d ata 
based up on the 199 7 Nati onal Nutrition al Survey for adults a nd th e 1995 Natio nal Nut rition Survey of 
Australi a, for child ren. Th e NE DI ca lculation i s made in acco rdance with  Guideline s for predi cting 
dietary intake  of pesticid e resid ues (revi sed) [World Health Org anization, 1997]. 
The NEDI for pyra clostrobin is equivale nt to 1% of the ADI. It is t herefo re concluded that t he chroni c 
dietary expo sure is small a nd the risk is accepta ble.

Toxicological / Public Health Ass essment   
It has be en determin ed th at the use of pyracl ostrobin as a fungi cide for use on grapes, according t o 
the GAP sp ecified a bove, is very unli kely to pose any health ri sks f rom consumption of the ha rvested  
commodity.   
Other International MRLs 
To meet Ne w Zeal and’s obligation s unde r the Agre ement on  the Applica tion of Sanitary an d 
Phytosanitary Measures the prop osed MRL will be notified to the Wo rld T rade Organi zation.  Any  
country may cho ose to co mment if they believe t he proposed MRL  represents a barrier to thei r trade.
