Modification of the existing maximum residue levels for pyriproxyfen in apricots and peaches.

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Sumitomo Chemical Agro Europe S.A.S. submitted a request to the competent national authority in Greece to modify the existing maximum residue levels (MRLs) for the active substance pyriproxyfen in apricots and peaches. The data submitted in support of the request were found to be sufficient to derive MRL proposal of 0.4 mg/kg for apricots, whereas for peaches an MRL amendment is not necessary. Adequate analytical methods for enforcement are available to control the residues of pyriproxyfen on the commodities under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the intended use of pyriproxyfen on apricots and peaches according to the reported agricultural practice is unlikely to present a risk to consumer health.

Summary

In accordance with Article 6 of Regulation (EC) No 396/2005, Sumitomo Chemical Agro Europe S.A.S. submitted an application to the competent national authority in Greece (evaluating Member State, EMS) to modify the existing maximum residue levels (MRLs) for the active substance pyriproxyfen in apricots and peaches. The EMS drafted an evaluation report in accordance with Article 8 of Regulation (EC) No 396/2005, which was submitted to the European Commission and forwarded to the European Food Safety Authority (EFSA) on 28 February 2022. To accommodate for the intended southern Europe (SEU) uses of pyriproxyfen, the EMS proposed to raise the existing MRLs for apricots from the limit of quantification (LOQ) of 0.05 mg/kg to 0.4 mg/kg and for peaches to lower the existing MRL set at 0.5 mg/kg to 0.4 mg/kg.

EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation. EFSA identified data gaps, which were requested from the EMS. On 21 July 2022 the EMS submitted a revised evaluation report (Greece, 2022), which replaced the previously submitted evaluation report.

Based on the conclusions derived by EFSA in the framework of Regulation (EC) No 1107/2009, the data evaluated under previous MRL assessments, and the additional data provided by the EMS in the framework of this application, the following conclusions are derived.

The metabolism of pyriproxyfen following foliar application was investigated in crops belonging to the groups of fruit crops and pulses/oilseeds, indicating that parent pyriproxyfen is the relevant residue in these crop groups. As the proposed uses of pyriproxyfen is on permanent crops, investigations on the nature and magnitude of residues in rotational crops are not required. Studies investigating the effect of processing on the nature of pyriproxyfen (hydrolysis studies) demonstrated that the active substance is hydrolytically stable.

The residue definitions for fruit crops and pulses/oilseeds were proposed by the EU pesticides peer review as ‘pyriproxyfen’ for enforcement and risk assessment. These residue definitions are applicable also to rotational crops and processed products.

EFSA concluded that for the fruit crops assessed in this application, metabolism of pyriproxyfen 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 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 commodities assessed (LOQ).

The available residue trials are sufficient to derive an MRL proposal of 0.4 mg/kg for apricots and peaches. However, in contrast to the proposal of the EMS and the applicant, the lowering of the existing MRL of 0.5 mg/kg for peaches is not supported by EFSA since it may cover other existing EU authorisations of pyriproxyfen.

The studies investigating the effect of processing on the magnitude of pyriproxyfen residues in processed apricots and/or peaches have not been provided and were requested. The applicant referred to processing studies with citrus fruits and tomatoes from the EU pesticides peer review where a significant reduction of residues is observed in juicing, canning and primary processing, but residues concentrate in tomato puree and citrus pomaces. Only the data on citrus fruit marmalade can be extrapolated to stone fruit marmalade, but as no consumption data of peach/apricot marmalade are available to EFSA, this processing factor is currently not applicable. Overall, considering the low contribution of residues in raw agricultural commodity (RAC) apricots (0.03% acceptable daily intake (ADI)) and peaches (0.12% ADI) to the total consumer exposure, EFSA concludes that the lack of additional processing studies with stone fruits is a minor deficiency not considerably affecting the outcome of the exposure calculation, currently with a wide margin of safety. The need for specific processing studies will be further assessed in the MRL review when information on the authorised pyriproxyfen uses is available.

Residues of pyriproxyfen in commodities of animal origin were not assessed since apricots and peaches are normally not fed to livestock.

The toxicological profile of pyriproxyfen 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 ADI of 0.05 mg/kg body weight (bw) per day and an acute reference dose (ARfD) of 1 mg/kg bw.

The consumer risk assessment was performed with revision 3.1 of the EFSA Pesticide Residues Intake Model (PRIMo). The short‐term exposure assessment was performed only for residues in apricots and peaches and did not exceed the ARfD, accounting for a maximum of 0.8% of the ARfD and 2.3% of the ARfD, respectively.

The estimated long‐term dietary intake accounted for a maximum of 22% of ADI (NL toddler diet). The contribution of residues expected in apricots and peaches to the overall long‐term exposure accounted for a maximum of 0.03% of the ADI for apricots and 0.12% of the ADI for peaches.

EFSA concluded that the proposed use of pyriproxyfen on apricots and peaches will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a risk to consumers' health.

EFSA notes that the conclusions of this assessment might be subject to modifications when the review of the existing EU MRLs for pyriproxyfen in accordance with the Article 12 of Regulation (EC) No 396/2005 is completed.

EFSA proposes to amend the existing MRLs as reported in the summary table below.

Full details of all end points and the consumer risk assessment can be found in Appendices Appendix B – List of end points, Appendix C – Pesticide Residue Intake Model (PRIMo), Appendix D – Input values for the exposure calculations–Appendix B – List of end points, Appendix C – Pesticide Residue Intake Model (PRIMo), Appendix D – Input values for the exposure calculations.

Assessment

The European Food Safety Authority (EFSA) received an application to modify the existing maximum residue levels (MRLs) for pyriproxyfen in apricots and peaches. The detailed description of the intended southern Europe (SEU) uses of pyriproxyfen on these fruit crops, which are the basis for the current MRL application, is reported in Appendix A.

Pyriproxyfen is the ISO common name for 4‐phenoxyphenyl (RS)‐2‐(2‐pyridyloxy)propyl ether (IUPAC). The chemical structures of the active substance and its main metabolites are reported in Appendix E.

Pyriproxyfen is an insecticide, which was evaluated in the framework of Regulation (EC) No 1107/20091 with the Netherlands designated as rapporteur Member State (RMS) for the representative uses on citrus fruits, pome fruits (apple, pears), tomatoes, ornamentals (field use) and tomatoes, ornamentals (greenhouse application). The renewal assessment report (RAR) prepared by the RMS has been peer reviewed by EFSA (2019b). The decision on the renewal of pyriproxyfen entered into force on 1 August 20202.

The EU MRLs for pyriproxyfen are established in Annex III of Regulation (EC) No 396/20053. The review of existing MRLs according to Article 12 of Regulation (EC) No 396/2005 (MRL review) has not yet been completed but is currently ongoing. The representative uses on tomatoes, pome fruits and citrus fruits according to good agricultural practices (GAPs) in the EU were assessed during the approval of pyriproxyfen under Regulation (EC) No 1107/2009; additionally, the MRL application on citrus fruits was assessed (EFSA, 2019b). Prior to the EU pesticides peer review EFSA has issued several reasoned opinions on the modification of MRLs for pyriproxyfen (EFSA, 2013, 2016). The proposals from these reasoned opinions have been considered in the MRL legislation4. Certain Codex maximum residue limits (CXLs) have been taken over in the recent EU MRL legislation (EFSA, 2019c; FAO, 2019).

In accordance with Article 6 of Regulation (EC) No 396/2005, Sumitomo Chemical Agro Europe S.A.S. submitted an application to the competent national authority in Greece (evaluating Member State, EMS) to modify the existing MRLs for the active substance pyriproxyfen in apricots and peaches. The EMS drafted an evaluation report in accordance with Article 8 of Regulation (EC) No 396/2005, which was submitted to the European Commission and forwarded to EFSA on 28 February 2022. To accommodate for the intended SEU uses of pyriproxyfen, the EMS proposed to raise the existing MRL for apricots from the limit of quantification (LOQ) to 0.4 mg/kg and for peaches to lower the existing MRL from 0.5 mg/kg to 0.4 mg/kg.

EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation. EFSA identified data gaps, which were requested from the EMS. On 21 July 2022 the EMS submitted a revised evaluation report (Greece, 2022), which replaced the previously submitted evaluation report.

EFSA based its assessment on the evaluation report submitted by the EMS (Greece, 2022), the RAR and its revision (Netherlands, 2017, 2019) prepared under Regulation (EC) No 1107/2009, the Commission review report on pyriproxyfen (European Commission, 2020a), the conclusion on the peer review of the pesticide risk assessment of the active substance pyriproxyfen (EFSA, 2019b), as well as the conclusions from previous EFSA opinions on pyriproxyfen (EFSA, 2013, 2016), including the EFSA output on the Scientific support for preparing an EU position for the 51st Session of the CCPR (EFSA, 2019c).

For this application, the data requirements established in Commission Regulation (EU) No 283/20135 and the guidance documents applicable at the date of submission of the application to the EMS are applicable (European Commission, 2010, 2017, 2018, 2020b, 2021; OECD, 2007a,b,c,d,e,f, 2008a,b, 2009a,b, 2011, 2013, 2016, 2018). 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 546/20116.

A selected list of end points of the studies assessed by EFSA in the framework of this MRL application including the end points of relevant studies assessed previously, is presented in Appendix B.

The evaluation report submitted by the EMS (Greece, 2022) 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.

Residues in plants

Nature of residues and methods of analysis in plants

Nature of residues in primary crops

The metabolism of pyriproxyfen in primary crops belonging to the group of fruit crops (apples, tomatoes, cucumbers, oranges) and pulses/oilseeds (cotton) has been investigated in the framework of the EU pesticides peer review (EFSA, 2019b). In the crops tested, following foliar treatment, parent compound was the main residue, representing between 4% (cotton) and 68% (tomato) of the total radioactive residues (TRRs). Other metabolites found above 10% TRR were 4’‐OH‐PYR (in cucumbers), PYPA (in apples and tomatoes), and POPA (in cucumbers), but in low absolute values. These compounds were concluded to be not genotoxic and therefore were not considered further by the EU pesticides peer review (EFSA, 2019b).

For the intended use on apricots and peaches, the metabolic behaviour of pyriproxyfen in primary crops is sufficiently addressed.

Nature of residues in rotational crops

As the proposed use of pyriproxyfen is on permanent crops, investigations on the nature of residues in rotational crops are not required. Confined rotational crops studies were assessed in the EU pesticides peer review (EFSA, 2019b).

Nature of residues in processed commodities

The effect of processing on the nature of pyriproxyfen residues was investigated in the framework of the EU pesticides peer review (EFSA, 2019b). These studies showed that the pyriproxyfen is hydrolytically stable under standard processing conditions.

Analytical methods for enforcement purposes in plant commodities

Analytical enforcement methods for the determination of pyriproxyfen residues in all types of plant matrices were assessed during the EU pesticides peer review (EFSA, 2019b). The methods available are sufficiently validated for the determination of residues of pyriproxyfen at or above the LOQ of 0.01 mg/kg in high‐water content commodities, to which apricots and peaches belong. Extraction efficiency of the analytical method for enforcement was verified in high‐water content commodities.

Storage stability of residues in plants

The stability of pyriproxyfen in plants stored under frozen conditions was investigated in the framework of the EU pesticides peer review (EFSA, 2019b). It was demonstrated that in high water content crop matrices residues were stable for at least 12 months when stored at −18°C.

In addition, a new storage stability study has been submitted and assessed in the framework of this application (Greece, 2022). Samples of apple (whole fruit), soybean (seeds), field bean (dried), wheat (grain) and orange (whole fruit) were spiked with a known amount of pyriproxyfen, stored frozen at −18°C and analysed at five different time intervals up to around 1 year. Residue levels in the samples were determined as pyriproxyfen using the validated analytical method QuEChERS (EN 1562:2008). The results of the study showed that pyriproxyfen residues are stable in apple, soybean, field bean, wheat and orange when stored frozen at −18°C for up to 365–371 days.

Proposed residue definitions

Based on the metabolic pattern identified in metabolism studies, the results of hydrolysis studies, the toxicological significance of metabolites and the capabilities of analytical enforcement method, the following residue definitions were proposed during the EU pesticides peer review:

residue definition for risk assessment: pyriproxyfen

residue definition for enforcement: pyriproxyfen.

The residue definitions are also applicable to rotational crops and processed products but are restricted to fruit and pulses/oilseeds crop groups for foliar treatments.

The residue definition for enforcement set in Regulation (EC) No 396/2005 is identical with the above‐mentioned residue definition.

EFSA concluded that these residue definitions are appropriate for the crops under assessment and no further information is required.

Magnitude of residues in plants

Magnitude of residues in primary crops

In support of the MRL application, the applicant submitted GAP‐compliant residue trials performed in France, Spain, Italy and Greece on apricots (four trials) and peaches (six trials). The applicant proposed to derive one MRL proposal for both fruit crops on the basis of a combined residue data set on apricots and peaches. According to the Technical Guidelines SANTE/2019/12752 (European Commission, 2020b), the residue data on apricots and peaches can be combined to derive MRL proposal.

The number of trials is sufficient to derive an MRL proposal of 0.4 mg/kg in support of the intended SEU use of pyriproxyfen on peaches and apricots. It is noted that the existing EU MRL for peaches is higher (0.5 mg/kg) and the applicant and the EMS proposed to lower it to 0.4 mg/kg.

The samples were analysed for the parent compound. According to the assessment of the EMS, the methods used were sufficiently validated and fit for purpose (Greece, 2022). The samples of these residue trials were stored under conditions for which integrity of the samples has been demonstrated.

Magnitude of residues in rotational crops

As the proposed use of pyriproxyfen is on permanent crops investigations on the magnitude of residues in rotational crops are not required.

Magnitude of residues in honey

Apricots and peaches are classified as melliferous crops (European Commission, 2018). However, since the active substance is intended to be applied after the flowering period, further investigation is not required in the framework of the present MRL assessment.

Magnitude of residues in processed commodities

Studies investigating the effect of processing on the magnitude of pyriproxyfen residues in processed commodities of apricots and peaches were not submitted within this application. Considering that residues in unprocessed apricots and peaches (raw agricultural commodity, RAC) occur above 0.1 mg/kg, processing data are required in accordance with Commission Regulation (EU) No 283/2013.

During the assessment of the MRL application, EFSA requested the applicant to provide processing studies with the crops under consideration or to provide a justification on why such studies were not performed. In response to this data requirement the applicant referred to processing studies with citrus fruits and tomatoes as assessed in the EU pesticides peer review demonstrating that significant reduction of residues is observed in citrus and tomato juice, canned citrus fruits and tomato as well as in citrus marmalade; a concentration of residues is observed in tomato puree and processing by products of citrus fruits (wet and dry pomace, press cake) (EFSA, 2019b).

According to the OECD guideline (OECD, 2008a), the extrapolation of results from processing studies performed with citrus fruits to stone fruits is accepted only when processing procedures refer to the preparation of fruit products such as marmalades, jams, jellies, purees/sauces (primary procedures only) but is not supported for processes like juice preparation and canning. Thus, only the data on citrus fruit marmalade can be extrapolated to stone fruit marmalade, with the respective processing factor of 0.16 as derived by the EU pesticides peer review. However, no consumption data of stone fruit marmalade are available in EFSA PRIMo rev. 3.1, therefore this processing factor is currently not applicable.

Considering the low contribution of residues in RAC apricots (0.03% acceptable daily intake (ADI)) and peaches (0.12% ADI) to the overall consumer exposure, EFSA concludes that the lack of additional processing studies with stone fruits is a minor deficiency not considerably affecting the outcome of the exposure calculation, currently with a wide margin of safety. It is also noted that this conclusion might be subject to modifications once the review of existing EU MRLs for pyriproxyfen under Article 12 of Regulation (EC) No 396/2005 is completed.

Proposed MRLs

The available data are considered sufficient to derive an MRL proposal as well as risk assessment values for the commodities under evaluation (see Appendix B.4). In Section B.3, EFSA assessed whether residues in peaches and apricots resulting from the intended use are likely to pose a consumer health risk.

Residues in livestock

Not relevant as apricots and peaches are not used for feed purposes.

Consumer risk assessment

EFSA performed a dietary risk assessment using revision 3.1 of the EFSA PRIMo (EFSA, 2018, 2019a). This exposure assessment model contains food consumption data for different sub‐groups 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 values for pyriproxyfen used in the risk assessment (i.e., ADI and acute reference dose (ARfD) values) were derived in the framework of the EU pesticides peer review (European Commission, 2020a).

Short‐term (acute) dietary risk assessment

The short‐term exposure assessment was performed only for the commodities assessed in this application in accordance with the internationally agreed methodology (FAO, 2016). The calculations were based on the highest residue (HR) value as derived from the submitted supervised field trials for apricots and peaches (see Appendix D.1). The short‐term exposure did not exceed the ARfD for any the crops assessed in this application: 0.8% of the ARfD for apricots (DE child diet) and 2.3% of the ARfD for peaches (NL toddler diet) (see Appendix B.3).

Long‐term (chronic) dietary risk assessment

The long‐term exposure assessment was performed, taking into account the supervised trials median residue (STMR) value as derived for apricots from the residue trials assessed in this application; for peaches a higher STMR value supporting the existing EU MRL and derived in the previous EFSA assessment (EFSA, 2013), was used as an input value. For the remaining commodities covered by the MRL regulation, the existing EU MRLs and STMR values derived in previous MRL applications, including those related to the safe CXLs implemented in the EU legislation, were selected as input values (EFSA, 2013, 2016; FAO, 2019). The complete list of input values is presented in Appendix D.1.

The estimated long‐term dietary intake was up to 22% of the ADI (NL toddler diet). The contribution of residues expected in the commodities assessed in this application to the overall long‐term exposure is low and is presented in more detail in Appendix B.3.

EFSA concluded that the long‐term intake of residues of pyriproxyfen resulting from the existing and the intended uses is unlikely to present a risk to consumer health.

EFSA notes that a more realistic long‐term consumer risk assessment will be performed in the framework of the currently ongoing Article 12 MRL review, when full information on authorised uses of pyriproxyfen and additional residue data will be available to EFSA.

For further details on the exposure calculations, a screenshot of the Report sheet of the PRIMo is presented in Appendix C.

Conclusion and recommendations

The data submitted in support of this MRL application were found to be sufficient to derive an MRL proposal for apricots and peaches.

EFSA concluded that the proposed use of pyriproxyfen on apricots and peaches will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a risk to consumers' health.

EFSA notes that the conclusions of this assessment might be subject to modifications when the review of the existing EU MRLs for pyriproxyfen is performed in accordance with the Article 12 of Regulation (EC) No 396/2005.

0140010	Apricots	0.05*	0.4	The submitted data are sufficient to derive an MRL proposal for the SEU use. Risk for consumers unlikely.
0140030	Peaches	0.5	No change	The submitted data are sufficient to derive an MRL proposal of 0.4 mg/kg for the SEU use, which is lower than the existing MRL. The proposal of the applicant and the EMS to lower the EU MRL is not supported as the MRL may be required to support other existing EU authorisations of pyriproxyfen. Risk for consumers unlikely.

MRL: maximum residue level; SEU: southern Europe; EMS: evaluating Member State.

Indicates that the MRL is set at the limit of analytical quantification (LOQ).

Commodity code number according to Annex I of Regulation (EC) No 396/2005.

Fat soluble.
