Abstract

In accordance with Article 53 of Regulation (EC) 1107/2009, the United Kingdom granted a 120-day emergency authorisation for the use of cyantraniliprole in leek. In order to accommodate for the new use, the Agriculture & Horticulture Development Board submitted an application to raise the existing maximum residue level (MRL) for the crop concerned. The United Kingdom, as evaluating Member State, summarised the data provided by the applicant in an evaluation report which was submitted to the European Commission and forwarded to EFSA. Sufficient residue trials are available to derive an MRL proposal of 0.6 mg/kg for leeks in accordance with the emergency authorised good agricultural practice (GAP). Adequate analytical methods for enforcement are available to control the residues of cyantraniliprole in the commodities under consideration. Based on the risk assessment results, EFSA concluded that intake of residues resulting from the use of cyantraniliprole according to the reported agricultural practice is unlikely to present a risk to consumer health.

Summary

In accordance with the provisions of Article 53 of Regulation (EC) 1107/2009, the United Kingdom granted an emergency authorisation for the placing on the market of a plant protection product containing the active substance cyantraniliprole, for a period not exceeding 120 days, for limited and controlled use in leeks. The emergency use is expected to lead to residues exceeding the existing maximum residue level (MRL) and the United Kingdom has authorised the placing on the market within its territory of treated leeks not complying with the existing European Union (EU) MRL, in accordance with Article 18(4) of Regulation (EC) No 396/2005 (hereinafter referred to as ‘the MRL Regulation’). In order to accommodate the use of cyantraniliprole according to the authorised good agricultural practices (GAPs), the Agriculture & Horticulture Development Board submitted an application under Article 6(2) of the MRL Regulation to set a specific MRLs for cyantraniliprole in leeks. The United Kingdom, as evaluating Member State (EMS), assessed the data provided by the applicant and drafted an evaluation report in accordance with Article 8 of the MRL Regulation, which was submitted to the European Commission and forwarded to EFSA. The EMS proposed that a temporary MRL in the framework of Article 16 of the MRL Regulation is justified since it is based on an emergency authorisation of a plant protection product in accordance with Article 53 of Regulation (EC) 1107/2009, and the products concerned constitute a minor component of consumers’ diet and the expected residues following the emergency use do not pose an unacceptable risk to consumers or animals. The EMS proposed to raise the existing MRLs of cyantraniliprole in leeks from the limit of quantification (LOQ) of 0.01 mg/kg to 0.8 mg/kg on the basis of the combined northern Europe (NEU) and southern Europe (SEU) data set. EFSA has based its assessment on the evaluation report submitted by the EMS, the draft assessment report (DAR) prepared under Regulation (EC) No 1107/2009, the European Commission review report on cyantraniliprole, the conclusion on the peer review of the pesticide risk assessment of the active substance cyantraniliprole, the JMPR evaluation reports as well as the conclusions from previous EFSA opinions on cyantraniliprole. The metabolism of cyantraniliprole following either foliar or soil applications in primary crops belonging to the fruit, leafy, cereals/grass, pulses/oilseeds crop groups has been investigated in the framework of the EU pesticides peer review. The possible transfer of cyantraniliprole residues to crops that are grown in crop rotation has been assessed in EU pesticides peer review. Since the accumulation of very persistent metabolites is expected following multiple years of consecutive applications, the peer review concluded that long‐term rotational crop studies are required to investigate the magnitude of residues of cyantraniliprole and its most persistent metabolites. Considering that the GAP under assessment was granted for a limited period of 120 days, the requested long‐term rotational crop studies are of low relevance. In general, EFSA recommends that Member States should consider this point when granting authorisations and where relevant, take appropriate risk mitigation measures in order to avoid the presence of residues of cyantraniliprole and relevant metabolites in rotational crops. On the basis of standard hydrolysis studies, the peer review proposed the residue definitions in processed commodities as cyantraniliprole for enforcement and as the sum of cyantraniliprole and IN‐J9Z38 expressed as cyantraniliprole for risk assessment. Considering that two additional degradation products were formed in significant levels in cooked spinach (i.e. IN‐N5M09 and IN‐F6L99), the peer review requested additional toxicological data for these compounds. The toxicological relevance of these metabolites should be further assessed, e.g. in the framework of the MRL review. EFSA concluded that for the crops assessed in this application, metabolism of cyantraniliprole in primary crops and the possible degradation in processed products has been sufficiently addressed and that the previously derived residue definitions are applicable. Sufficiently validated analytical methods based on liquid chromatography with tandem mass spectrometry (LC–MS/MS) are available to quantify residues in the crops assessed in this application according to the enforcement residue definition. The methods enable quantification of residues at or above 0.01 mg/kg in the crops assessed (LOQ). The submitted trials on leeks were performed at higher total application rates than the target application rate for the emergency authorised GAP and EFSA applied the proportionality approach to estimate the residues values expected at the GAP target application rate. In contrast to the EMS, EFSA did not use the SEU trials to derive the MRL proposal, since the relevant GAP is authorised only in the UK. The number and quality of the trials are sufficient to derive a MRL of 0.6 mg/kg for leeks in accordance with the emergency authorised GAP on the basis of the NEU residue trials. Specific studies investigating the magnitude of cyantraniliprole residues in processed commodities were assessed during the peer review and a processing factor (PF) of 0.2 and a conversion factor for risk assessment (CF) of 8.0 derived for spinaches (leaves, cooked) are considered appropriate for extrapolation to leeks. Residues of cyantraniliprole in commodities of animal origin were not assessed since the crop under consideration in this MRL application is normally not fed to livestock. The toxicological profile of cyantraniliprole was assessed in the framework of the EU pesticides peer review under Regulation (EC) No 1107/2009 and the data were sufficient to derive an acceptable daily intake (ADI) of 0.01 mg/kg body weight (bw) per day. The setting of an acute reference dose (ARfD) has been deemed unnecessary, and therefore, a short‐term dietary risk assessment is not required. The consumer risk assessment was performed with revision 2 of the EFSA Pesticide Residues Intake Model (PRIMo). The estimated long‐term dietary intake was in the range of 8.9–74% of the ADI and the maximum contribution of residues expected in leeks is 0.9% of ADI (FR toddler). EFSA concluded that the proposed use of cyantraniliprole on leeks will not result in a consumer exposure exceeding the toxicological reference value and therefore is unlikely to pose a risk to consumer health. EFSA proposes to amend the existing MRLs as reported in the summary table below. Existing EU MRL (mg/kg) Proposed EU MRL (mg/kg) The submitted data are sufficient to derive an MRL proposal of 0.6 mg/kg for the emergency authorised GAP on leeks on the basis of NEU residue trials.

Background

In accordance with the provisions of Article 53 of Regulation (EC) 1107/20091, the United Kingdom granted an emergency authorisation for the placing on the market of a plant protection product containing the active substance cyantraniliprole, for a period not exceeding 120 days, for limited and controlled use in leeks, on the basis that such a measure appears necessary because of a danger which cannot be contained by any other reasonable means. The emergency use is expected to lead to residues exceeding the existing maximum residue level (MRL) and the United Kingdom has authorised the placing on the market within its territory of treated leeks not complying with the existing European Union (EU) MRL, in accordance with Article 18(4) of Regulation (EC) No 396/20052 (hereinafter referred to as ‘the MRL Regulation’). In order to accommodate the use of cyantraniliprole according to the authorised good agricultural practices, the Agriculture & Horticulture Development Board3 submitted an application under Article 6(2) of the MRL Regulation to set specific MRLs for cyantraniliprole in leeks. The United Kingdom, as evaluating Member State (EMS), assessed the data provided by the applicant and drafted an evaluation report in accordance with Article 8 of the MRL Regulation, which was submitted to the European Commission and forwarded to EFSA on 2 October 2017. The EMS proposed that a temporary MRL in the framework of Article 16 of the MRL Regulation is justified since it is based on an emergency authorisation of a plant protection product in accordance with Article 53 of Regulation (EC) 1107/2009, and the products concerned constitute a minor component of consumers’ diet and the expected residues following the emergency use do not pose an unacceptable risk to consumers or animals (United Kingdom, 2017). The application was included in the EFSA Register of Questions with the reference number EFSA‐Q‐2017‐00684 and the following subject: Cyantraniliprole – MRL in leeks. The EMS proposed to raise the existing MRLs of cyantraniliprole in leeks from the limit of quantification (LOQ) of 0.01–0.8 mg/kg on the basis of the combined northern Europe (NEU) and southern Europe (SEU) data set. EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation.

Terms of Reference

In accordance with Article 10 of Regulation (EC) No 396/2005, EFSA shall assess the application and the evaluation report and give a reasoned opinion on the risks to the consumer and where relevant to animals associated with the setting of the requested MRLs. The opinion shall include: An assessment of whether the analytical method for routine monitoring proposed in the application is appropriate for the intended control purposes; The anticipated LOQ for the pesticide/product combination; An assessment of the risks of the acceptable daily intake (ADI) and acute reference dose (ARfD) being exceeded as a result of the modification of the MRL; The contribution to the intake due to the residues in the product for which the MRLs were requested; Any other element relevant to the risk assessment. In accordance with Article 11 of the MRL regulation, EFSA shall give its reasoned opinion as soon as possible and at the latest within 3 months from the date of receipt of the application. The evaluation report submitted by the EMS (United Kingdom, 2017) and the exposure calculations using the EFSA Pesticide Residues Intake Model (PRIMo) are considered as supporting documents to this reasoned opinion and, thus, are made publicly available as background documents to this reasoned opinion.

The active substance and its use pattern

The detailed description of the intended use of cyantraniliprole which is the basis for the current MRL application is reported in Appendix A. Cyantraniliprole is the ISO common name for 3‐bromo‐1‐(3‐chloro‐2‐pyridyl)‐4′‐cyano‐2′‐methyl‐6′‐(methylcarbamoyl) pyrazole‐5‐carboxanilide (IUPAC). The chemical structures of the active substance and its main metabolites are reported in Appendix E. Cyantraniliprole was evaluated as a new active substance in the framework of Regulation (EC) No 1107/2009 with the United Kingdom designated as rapporteur Member State (RMS) for the representative uses as foliar applications on various crops. The draft assessment report (DAR) prepared by the RMS has been peer reviewed by EFSA (EFSA, 2014). Cyantraniliprole was approved4 for the use as an insecticide on 14 September 2016. The EU MRLs for cyantraniliprole are established in Annex II of Regulation (EC) No 396/2005. The review of existing MRLs according to Article 12 of Regulation (EC) No 396/2005 (MRL review) has not yet been completed. EFSA has issued several reasoned opinions on the modification of MRLs for cyantraniliprole (EFSA, 2015, 2016a,b, 2017). The proposals from these reasoned opinions have been considered in regulations5 for EU MRL legislation.

Assessment

EFSA has based its assessment on the evaluation report submitted by the EMS (United Kingdom, 2017), the DAR prepared under Regulation (EC) No 1107/2009 (United Kingdom, 2013), the European Commission review report on cyantraniliprole (European Commission, 2016), the conclusion on the peer review of the pesticide risk assessment of the active substance cyantraniliprole (EFSA, 2014), the JMPR evaluation reports (FAO, 2013, 2016), as well as the conclusions from previous EFSA opinions on cyantraniliprole (EFSA, 2015, 2016a,b, 2017). For this application, the data requirements established in Regulation (EU) No 544/20116 and the guidance documents applicable at the date of submission of the application to the EMS are applicable (European Commission, 1997a, b, c, d, e, f, g, 2000, 2010a,b, 2016; OECD, 2011, 2016). The assessment is performed in accordance with the legal provisions of the Uniform Principles for the Evaluation and the Authorisation of Plant Protection Products adopted by Commission Regulation (EU) No 546/2011.7 A selected list of end points of the studies assessed by EFSA in the framework of EU pesticides peer review, including the end points of studies submitted in support of the current MRL application, are presented in Appendix B.

Residues in plants

Nature of residues and methods of analysis in plants

Nature of residues in primary crops

The metabolism of cyantraniliprole following either foliar or soil applications in primary crops belonging to the fruit, leafy, cereals/grass, pulses/oilseeds crop groups has been investigated in the framework of the EU pesticides peer review (EFSA, 2014). No additional studies were submitted in the current MRL application. For the intended use, the metabolic behaviour in primary crops is sufficiently addressed.

Nature of residues in rotational crops

The crop under consideration can be grown in rotation with other plants, and therefore, the nature of possible residues in succeeding crops resulting from the use on primary crops has to be assessed. The soil degradation studies demonstrated that cyantraniliprole is of moderate to high persistence, with a maximum DT90 of 376 days, whilst several metabolites demonstrated a moderate to very high persistence with DT90 values estimated to be in the range of 4–9 years (EFSA, 2014), and therefore, studies on rotational crops are required (European Commission, 1997c). Studies on the nature of cyantraniliprole residues in rotational crops were assessed in the framework of the peer review (EFSA, 2014). In the peer review, EFSA considered that the available studies on rotational crops were not fully appropriate to address the transfer of soil metabolites to plants, because they were conducted with a single application, while the DT90 values for several metabolites in soil were estimated to be in the range of 4–9 years and therefore open to accumulation following several years of consecutive applications. The current MRL application did not provide new information on the nature of residues in rotational crops.

Nature of residues in processed commodities

The effect of processing on the nature of cyantraniliprole was investigated in the framework of the EU pesticides peer review. On the basis of standard hydrolysis studies, the residue definitions in processed commodities were proposed as cyantraniliprole for enforcement and as the sum of cyantraniliprole and IN‐J9Z38 expressed as cyantraniliprole for risk assessment (EFSA, 2014). Considering that two additional degradation products were formed in significant levels in cooked spinach (i.e. IN‐N5M09 and IN‐F6L99), the peer review requested additional toxicological data for these compounds. The toxicological relevance of these metabolites should be further assessed, e.g. in the framework of the MRL review.

Methods of analysis in plants

Analytical methods for the determination of cyantraniliprole residues were assessed during the EU pesticides peer review under Regulation (EC) No 1107/2009 and were shown to be fully validated in high water‐, high oil‐, high acid‐ and high starch content matrices for the determination of residues of cyantraniliprole and its metabolite IN‐J9Z38 at a LOQ of 0.01 mg/kg for each analyte (EFSA, 2014).

Stability of residues in plants

The storage stability of cyantraniliprole residues in plants stored under frozen conditions was investigated in the framework of the EU pesticides peer review (EFSA, 2014). It was demonstrated that for commodities belonging to the high water‐content group (which includes leeks), residues were stable for at least 24 months when stored at −20°C.

Proposed residue definitions

Based on the pattern for the metabolism of cyantraniliprole in plants, the results of hydrolysis studies, the toxicological significance of metabolites and/or degradation products, the capabilities of enforcement analytical methods, the following residue definitions were proposed as follows: Residue definition for risk assessment for primary crops: Cyantraniliprole (except for processed commodities) Residue definition for risk assessment for processed commodities: Sum of cyantraniliprole and IN‐J9Z38 expressed as cyantraniliprole Residue definition for enforcement: Cyantraniliprole The residue definition for enforcement set in Regulation (EC) No 396/2005 is identical with the above‐mentioned residue definition. Taking into account the proposed use assessed in this application, EFSA concluded that these residue definitions are appropriate and no modification is required.

Magnitude of residues in plants

Magnitude of residues in primary crops

In support of the MRL application, the applicant submitted eight GAP‐compliant residue trials on NEU outdoor leeks conducted in the United Kingdom and northern France. The NEU trials were performed in two growing seasons (2010 and 2011). In addition, four outdoor residue trials on leeks conducted in SEU were submitted (southern France; 2011 growing season). All trials were performed with two foliar spray applications at a target application rate of 100 g a.s./ha with an oil dispersion formulation containing 100 g/L cyantraniliprole. In accordance with the GAP, an oil adjuvant was added to the spray mix in all trials. In accordance with the data requirements, leek is considered a major crop in NEU for which a minimum of eight GAP‐compliant trials are required (European Commission, 2017). Therefore, the number of trials compliant with the GAP is sufficient to support an MRL proposal. In contrast to the EMS, EFSA did not use the SEU trials to derive the MRL proposal, since the relevant GAP is authorised only in the UK. The samples were analysed for the parent compound cyantraniliprole in accordance with the residue definitions for enforcement and risk assessment. Additional validation data for leeks were presented in the evaluation report and the analytical methods used were considered sufficiently validated and fit for purpose. The samples of these residue trials were stored under conditions, for which integrity of the samples has been demonstrated. The measured total application rates in the NEU trials were higher than the target total application rate by factors ranging between 1.32N and 1.38N. The other parameters of the trials were consistent with the emergency authorised GAP for leeks. Since all trials were overdosed, leading to a systematic bias, EFSA (in contrast to the EMS) scaled down the residues values using the proportionality approach in order to estimate the MRL proposal required for the emergency authorised GAP (CAC, 2013; OECD, 2016).

Magnitude of residues in rotational crops

The possible transfer of cyantraniliprole residues to crops that are grown in crop rotation has been assessed in EU pesticides peer review. In the peer review, EFSA considered that since accumulation of several very persistent metabolites is expected following multiple years of consecutive applications, the submitted trials conducted with a single seasonal application rate are not fully appropriate to address the transfer of cyantraniliprole residues in rotational crops (EFSA, 2014). The peer review concluded that long‐term rotational crop studies are required to investigate the magnitude of residues of cyantraniliprole and its most persistent metabolites. The current MRL application did not provide any new information on the magnitude of residues in rotational crops. Considering that the GAP under assessment was granted for a limited period of 120 days, the requested long‐term rotational crop studies are of low relevance. In general, EFSA recommends that Member States should consider this point when granting authorisations and where relevant, take appropriate risk mitigation measures in order to avoid the presence of residues of cyantraniliprole and relevant metabolites in rotational crops.

Magnitude of residues in processed commodities

Processing studies were not submitted in the framework of the current MRL application. Although the levels of cyantraniliprole residues expected in the raw agricultural commodity (RAC) exceed the trigger value of 0.1 mg/kg, processing studies are not necessary considering that the expected dietary exposure via residues in leeks is low. Studies investigating the effect of processing on the magnitude of cyantraniliprole residues were assessed during the peer review (EFSA, 2014). The processing factor (PF) of 0.2 and conversion factor for risk assessment (CF) of 8.0 derived for spinaches (leaves, cooked) are considered appropriate for extrapolation to leeks.

Proposed MRLs

The number and quality of the trials compliant with the NEU GAP are sufficient to derive a MRL of 0.6 mg/kg for leeks in accordance with the emergency authorised GAP. The available data which are considered appropriate to derive an MRL proposal and risk assessment values for the commodity under evaluation are summarised in Appendix B.1.2.1. In Section 3, EFSA assessed whether residues on these crops are likely to pose a consumer health risk.

Residues in livestock

The assessment of residues in livestock is not relevant to the present application as leeks are not used for animal feed purposes.

Consumer risk assessment

EFSA performed a dietary risk assessment using revision 2 of the EFSA PRIMo (EFSA, 2007). This exposure assessment model contains food consumption data for different subgroups of the EU population and allows the acute and chronic exposure assessment to be performed in accordance with the internationally agreed methodology for pesticide residues (FAO, 2016). The toxicological reference value for cyantraniliprole used in the risk assessment (ADI value) was derived in the framework of the EU pesticides peer review (EFSA, 2014). The long‐term exposure assessment was performed taking into account the scaled supervised trials median residue (STMR) values derived for the commodities assessed in this application; for the remaining commodities covered by the MRL regulation, the existing EU MRLs and STMR values derived in previous MRL applications and JMPR evaluations were selected as input values (FAO, 2013; EFSA, 2014, 2015, 2016a,b, 2017). The complete list of input values is presented in Appendix D.1. The estimated long‐term dietary intake was in the range of 8.9–74% of the ADI and the maximum contribution of residues expected in leeks is 0.9% of ADI (FR toddler). Further detail on the contribution of residues expected in the commodities assessed in this application to the overall long‐term exposure is provided in the report sheet of the PRIMo, which is presented in Appendix C. EFSA concluded that the long‐term intake of residues of cyantraniliprole resulting from the existing uses and the emergency authorised use on leeks is unlikely to present a risk to consumer health.

Conclusions and recommendations

The number and quality of the submitted trials are sufficient to derive a MRL of 0.6 mg/kg for leeks in accordance with the emergency authorised GAP. Adequate analytical methods for enforcement are available to control the residues of cyantraniliprole in plant matrices under consideration. Based on the risk assessment results, EFSA concluded that the intake of residues resulting from the use of cyantraniliprole according to the emergency authorised agricultural practice is unlikely to present a risk to consumer health. The MRL recommendation is summarised in Appendix B.4.

Processing factors

Processing studies were not submitted in the framework of the current MRL application and are not required because the theoretical maximum daily intake (TMDI) from the consumption of leeks is less than 10% of the ADI (European Commission, 1997d). The processing factor derived for spinach (leaves, cooked) is considered appropriate for extrapolation to leeks.

Existing EU MRL (mg/kg) Proposed EU MRL (mg/kg) The submitted data are sufficient to derive an MRL proposal of 0.6 mg/kg for the emergency authorised GAP on leeks on the basis of NEU residue trials. A consumer health concern is unlikely. Considering that the emergency authorisation was granted for a limited period of time (120 days), further risk management considerations are required to decide whether the proposed MRL should be established for a limited period of time. Some data gaps were identified in the peer review as regards processing and rotational crops that should be addressed, e.g. in the framework of the MRL review MRL: maximum residue level; NEU: northern Europe. *Indicates that the MRL is set at the limit of analytical quantification (LOQ).

Appendix D – Input values for the exposure calculations

STMR‐scaleda (indoor raspberries) Emergency authorisation under Article 53 of Regulation (EC) No 1107/2009. EFSA (2017) STMR: supervised trials median residue; PF: processing factor; CF: conversion factor for enforcement to risk assessment residue definition; ARfD: acute reference dose; YF: yield factor; MRL: maximum residue level. STMR‐scaled: residue trial values scaled assuming proportionality for estimation of residues at the GAP target application rate. Consumption figure in the PRIMo model is expressed for the raw commodity (grape). A yield factor (YF) of 0.7 is therefore considered to estimate the consumption figure for wine. Residue values in the FAO (2013) estimation of STMRs in products of animal origin are the sum of cyantraniliprole and metabolites IN‐N7B69, IN‐J9Z38, IN‐MLA84 and IN‐MYX98, expressed as cyantraniliprole. The range of metabolites in the FAO estimated STMRs is broader than the EU risk assessment residue definition; however, these values are considered appropriate for use in the exposure calculation. The EU MRL for cyantraniliprole in milk (Regulation (EU) 2017/626) is the same value as the 2013 CXL for cyantraniliprole in milk (0.02 mg/kg), and therefore, the 2013 FAO STMR value for milk is used for the exposure calculation. 3‐bromo‐1‐(3‐chloro‐2‐pyridyl)‐4′‐cyano‐2′‐methyl‐6′‐(methylcarbamoyl)pyrazole‐5‐carboxanilide MW: 473.72 g/mol.

The submitted data are sufficient to derive an MRL proposal of 0.6 mg/kg for the emergency authorised GAP on leeks on the basis of NEU residue trials.

A consumer health concern is unlikely.

Considering that the emergency authorisation was granted for a limited period of time (120 days); further risk management considerations are required to decide whether the proposed MRL should be established for a limited period of time. Some data gaps were identified in the peer review as regards processing and rotational crops that should be addressed, e.g. in the framework of the MRL review.

MRL: maximum residue level; NEU: northern Europe.

STMR: supervised trials median residue; PF: processing factor; CF: conversion factor for enforcement to risk assessment residue definition; ARfD: acute reference dose; YF: yield factor; MRL: maximum residue level.

STMR‐scaled: residue trial values scaled assuming proportionality for estimation of residues at the GAP target application rate.

Consumption figure in the PRIMo model is expressed for the raw commodity (grape). A yield factor (YF) of 0.7 is therefore considered to estimate the consumption figure for wine.

Residue values in the FAO (2013) estimation of STMRs in products of animal origin are the sum of cyantraniliprole and metabolites IN‐N7B69, IN‐J9Z38, IN‐MLA84 and IN‐MYX98, expressed as cyantraniliprole. The range of metabolites in the FAO estimated STMRs is broader than the EU risk assessment residue definition; however, these values are considered appropriate for use in the exposure calculation.

The EU MRL for cyantraniliprole in milk (Regulation (EU) 2017/626) is the same value as the 2013 CXL for cyantraniliprole in milk (0.02 mg/kg), and therefore, the 2013 FAO STMR value for milk is used for the exposure calculation.
