Targeted review of maximum residues levels (MRLs) for indoxacarb

Abstract

In compliance with Article 43 of Regulation (EC) No 396/2005, EFSA received a mandate from the European Commission to perform a targeted review of the maximum residue levels (MRLs) for indoxacarb based on Codex maximum residue limits (CXLs) or on import tolerances which might still be maintained after the expire of the approval of the active substance. EFSA screened the existing MRLs based on CXLs or on import tolerances considering the new toxicological reference values established during the peer review process for the renewal of the approval of indoxacarb and identified the MRLs for which an acute risk could not be excluded and several MRLs that are unlikely to pose a risk for consumers. Fall‐back MRLs could not be proposed for the commodities exceeding the new toxicological reference values as no further data were provided during the call for data. Therefore, risk managers may consider maintaining only the MRLs identified during the screening as safe for consumers. However, for some of the proposed MRLs, further consideration by risk managers is needed due to the uncertainties identified.

Summary

Indoxacarb was approved on 1 April 2006 by means of Commission Directive 2006/10/EC in the framework of Directive 91/414/EEC for use as an insecticide.

On 24 August 2011, the European Food Safety Authority (EFSA) published its reasoned opinion on the review of the existing maximum residues levels (MRLs) for the active substance indoxacarb in compliance with Article 12(2) of Regulation (EC) No 396/2005 and the proposed MRLs were implemented in Regulation EU No 668/2013. After completion of the MRL review, EFSA has provided scientific support for preparing an EU position on Codex maximum residue limits (CXLs) in indoxacarb for the 45th and 46th Session of the Codex Committee on Pesticide Residues. The CXLs adopted by the Codex Alimentarius Commission (CAC) have been included in Commission Regulation (EU) No 2015/845.

On 25 January 2018, EFSA finalised the conclusion on the peer review of the active substance according to Article 13 of Regulation (EU) No 844/2012 in the framework of the renewal of the approval under Regulation (EC) No 1107/2009. In the conclusion EFSA proposed to lower the existing acceptable daily intake (ADI) from 0.006 mg/kg body weight per day to 0.005 mg/kg body weight per day and the acute reference dose (ARfD) from 0.125 mg/kg body weight to 0.005 mg/kg body weight for indoxacarb.

Commission Implementing Regulation (EU) 2021/2081 concerning the non-renewal of approval of the active substance indoxacarb was adopted on 26 November 2021. The approval of indoxacarb was not renewed and a grace period was granted until 19 September 2022.

After the expiry of the grace period, when the EU authorisations will have been withdrawn, the maximum residue levels based on former EU uses will be lowered to the limit of quantification (LOQ) according to Reg (EC) No 396/2005. However, CXLs and some MRLs based on import tolerances exist for a range of commodities for which MRLs could be maintained in case they are safe for consumers.

To identify these MRLs considering the new toxicological reference values, EFSA was mandated by the European commission to perform a preliminary risk assessment of the existing EU MRLs covering CXLs or import tolerances. According to the exposure calculations (scenario 1), an acute risk could not be excluded for 20 commodities. For these commodities, EFSA asked MSs and the UK to report import tolerance fall-back Good Agricultural Practices (GAPs) together with supporting residue data. Since no fall-back GAPs were received and no refinement was possible, fall-back MRLs could not be derived.

A second exposure calculation (scenario 2) was performed replacing the risk assessment values for the commodities of concern identified in the first scenario with the LOQ of 0.01 mg/kg in the calculation. According to the results of this calculation, the highest chronic exposure declined to 53% of the ADI (Dutch toddler) and the highest acute exposure was calculated for basil, representing 99% of the ARfD.

Overall, the existing MRLs covering CXLs or import tolerance for cranberries, potatoes, sweet corn, basil, dry beans, dry peas, peanuts, soya beans, cotton seed, tea, milk, ruminants, swine and poultry tissues, and eggs are not expected to pose an unacceptable risk for consumers, and therefore risk managers may consider maintaining these MRLs. Nevertheless, further considerations are needed by risk managers regarding the MRLs for basil and milk for which the consumer risk assessment was affected by high level of uncertainty.

Background

Indoxacarb was first evaluated in the framework of Directive 91/414/EEC¹ with the Netherlands designated as rapporteur Member State (RMS). Following the peer review, which was not carried out by the European Food Safety Authority (EFSA), a decision on inclusion of the active substance in Annex I to Directive 91/414/EEC for the use as an insecticide was taken by means of Commission Directive 2006/10/EC².

The EU maximum residue levels (MRLs) for indoxacarb are established in Annex II of Regulation (EC) No 396/2005³. The existing MRLs were assessed in 2011 by EFSA according to Article 12 of Regulation (EFSA, 2011) and the proposed MRLs were implemented by Commission Regulation (EU) No 668/2013⁴. After completion of the MRL review, EFSA provided scientific support for preparing an EU position on Codex maximum residue limits (CXLs) in indoxacarb for the 45th and 46th Session of the Codex Committee on Pesticide Residues (EFSA, 2013c, 2014). The CXLs adopted by the Codex Alimentarius Commission (CAC) have been included, respectively, in Commission Regulation (EU) No 491/2014 and in Commission Regulation (EU) No 2015/845.

On 25 January 2018, EFSA finalised the conclusion on the peer review of the active substance according to Article 13 of Regulation (EU) No 844/2012⁵ in the framework of the renewal of the approval under Regulation (EC) No 1107/2009⁶ (EFSA, 2018a). In the conclusion EFSA proposed to lower the existing acceptable daily intake (ADI) from 0.006 mg/kg body weight per day to 0.005 mg/kg body weight per day and the acute reference dose (ARfD) from 0.125 mg/kg body weight to 0.005 mg/kg body weight for indoxacarb.

Commission Implementing Regulation (EU) 2021/2081 concerning the non-renewal of approval of the active substance indoxacarb was adopted on 26 November 2021. The approval of indoxacarb was not renewed because a critical area of concern was identified in relation to the high long-term risk to wild mammals, in particular the long-term risk to small herbivorous mammals. In addition, a high risk was identified to consumers and workers for the representative use in lettuce and to bees for the representative use in maize, sweet corn and lettuce for seed production. The grace period will expire on 19 September 2022.

After the expiry of the grace period, when the EU authorisations will have been withdrawn, the maximum residue levels based on former EU uses will be lowered to the limit of quantification. However, Codex maximum residue limits (CXLs) and some MRLs based on import tolerances exist for a range of commodities for which MRLs could be maintained in case they are safe for consumers.

Therefore, according to Article 43 of Regulation (EC) No 396/2005, EFSA has been requested by EC to perform a targeted review of the existing MRLs for the active substance indoxacarb covering CXLs or import tolerances.

On the basis of the data available in the MRL Review and in the Joint Meeting on Pesticide residues (JMPR) Evaluation reports, the data submitted by the EURLs and taking into account the conclusions derived by EFSA in the framework of Regulation (EC) No 1107/2009 for the renewal of approval of indoxacarb, EFSA prepared in May 2022 a draft reasoned opinion, which was circulated to Member States and EURLs for consultation via a written procedure. Comments received by 10 June 2022 were considered during the finalisation of this reasoned opinion.

The evaluation report submitted by the EURLs (2022) during the collection of data is considered as a supporting document to this reasoned opinion and, thus, made publicly available.

In addition, further supporting document to this reasoned opinion is the Member States consultation report (EFSA, 2022). Furthermore, the exposure calculations for all crops reported in the framework of this review performed using the EFSA Pesticide Residues Intake Model (PRIMo) are key supporting documents made publicly available as background document to this reasoned opinion. A screenshot of the report sheets of the PRIMo are presented in Appendix C.

Terms of Reference

According to Article 43 of Regulation (EC) No 396/2005, EFSA was requested to:

• •perform a preliminary assessment of the chronic and acute risk to consumers limited to existing MRLs based on Good Agricultural Practices authorised in third countries and/or on CXLs, considering the new lowered toxicological reference values and the newest version of PRIMo;
• •consult the EURLs on the LOQs achievable during routine analyses and Member States and the UK on information about Good Agricultural Practices authorised in third countries on the commodities of concern and already evaluated at Member State level, which might support setting of fall-back safe MRLs, where this is necessary in view of consumer protection;
• •consult the Member States and the EURLs on the draft reasoned opinion.
• •EFSA should base the assessment on the residue definitions for risk assessment and enforcement derived during the MRL review. EFSA should deliver the reasoned opinion by 18 August 2022.

The active substance and its use pattern

Indoxacarb is the ISO common name for methyl (S)-N-[7-chloro-2,3,4a,5-tetrahydro-4a-(methoxycarbonyl)indeno[1,2-e][1,3,4]oxadiazin-2-ylcarbonyl]-4′-(trifluoromethoxy)carbanilate ormethyl (S)-7-chloro-2,3,4a,5-tetrahydro-2-[methoxycarbonyl(4-trifluoromethoxyphenyl)carbamoyl]indeno[1,2-e][1,3,4]oxadiazine-4a-carboxylate (IUPAC).

The chemical structure of the active substance is reported in Appendix D.

The EU MRLs for indoxacarb are established in Annexes II of Regulation (EC) No 396/2005. Codex maximum residue limits (CXLs) for indoxacarb were also established by the Codex Alimentarius Commission (CAC).

Assessment

EFSA has based its assessment on the following documents:

• •the conclusion on the peer review of the pesticide risk assessment of the active substance indoxacarb (EFSA, 2018a);
• •the reasoned opinion on the review of the existing MRLs for indoxacarb according to Article 12 of Regulation (EC) No 396/2005 (EFSA, 2011);
• •the Joint Meeting on Pesticide residues (JMPR) Evaluation report (FAO, 2005, 2009, 2012, 2013).

The reasoned opinions published after the MRL review concerned European uses only and, therefore, were not further considered in the assessment.

The assessment is performed in accordance with the legal provisions of the uniform principles for evaluation and authorisation of plant protection products as set out in Commission Regulation (EU) No 546/2011⁷.

As the basis for this targeted assessment, EFSA performed a preliminary risk assessment considering the new toxicological reference values derived by EFSA in the framework of the renewal for the approval of the active substance (EFSA, 2018a), the MRLs and risk assessment values derived from the import tolerances assessed in the MRL review (EFSA, 2011), as well as all the CXLs and risk assessment values derived by the JMPR and covered by the MRLs implemented in the EU Legislation. In this preliminary assessment, the residue definitions for enforcement and risk assessment as derived during the MRL review were considered. In line with the terms of reference of the mandate existing MRLs based on EU uses and derived in the framework of the MRL review and in consequent MRL assessments were not considered, assuming that all European uses will be withdrawn.

Chronic and acute exposure calculations were performed using revision 3.1 of the EFSA PRIMo (EFSA, 2018b, 2019). All input values considered in the risk assessment are reported in Appendix A to this reasoned opinion while the results of the calculations are reported under Appendices B and C.

According to the results of the preliminary risk assessment (scenario 1), the highest chronic exposure was calculated for the Dutch toddler, representing 128% of the ADI. Main contributors of the exposure were apples (45%), milk (44%) and pears (18%). Regarding the acute exposure, concerns were identified for 20 existing MRLs derived from CXLs and/or import tolerances (apples, pears, apricots, cherries, peaches, plums, table and wine grapes, tomatoes, peppers, aubergines, cucumbers, gherkins, courgettes, melons, pumpkins, watermelons, broccoli, cauliflower, lettuce) with exposure exceeding up to 2,188% of the ARfD. The ARfD was not exceeded for the existing MRLs based on CXLs/import tolerance for cranberries, potatoes, sweet corn, basil, dry beans, dry peas, peanuts, soya beans, cotton seed, tea, milk, swine, ruminants and poultry tissues and eggs. It should be noted that no acute consumption data is included in PRIMo 3.1 for cotton seeds and therefore it was not possible to calculate the exposure for this commodity. Nevertheless, due to the low relevance of cotton seeds in European diets, residues in this commodity at the level of the existing MRL (1 mg/kg) are not expected to pose an unacceptable risk for European consumers.

Following preliminary risk assessment, as a second step, Member States and the United Kingdom⁸ were requested to submit by 7 April 2022 information about Good Agricultural Practices authorised in third countries and already evaluated at Member State level, which might support setting of fall-back import tolerance for the commodities of concern or any additional data allowing to refine the risk assessment. In parallel, the EURLs were invited to provide an Evaluation Report on the availability of analytical methods for enforcement and the LOQ achievable during routine analysis. In response to the data call, no fall-back Good Agricultural Practice (GAP) nor additional data were submitted by the Member States nor the UK while the EURLs provided the requested information confirming that for the enforcement of indoxacarb in plant and animal matrices the default LOQ of 0.01 mg/kg is achievable during routine analyses (EURLs, 2022).

A second exposure calculation (scenario 2) was therefore performed replacing the risk assessment values for the commodities of concern identified in the first scenario with the LOQ of 0.01 mg/kg in the calculation. According to the results of this calculation, the highest chronic exposure declined to 53% of the ADI (Dutch toddler) and the highest acute exposure was calculated for basil, representing 99% of the ARfD.

In addition, to support risk managers in the decision-making process, the LOQ for all the commodities for which no CXLs nor import tolerances are in place were screened, confirming that the default LOQ of 0.01 mg/kg is sufficiently protective for consumers.

EFSA notes that, although according to the internationally agreed methodology for acute risk assessment (which is based on the highest residue found in the supervised field trials) no acute consumer intake concerns were identified in the second calculation, for the uses on basil, cattle milk and meat (swine, bovine and sheep) the safety margin for acute exposure is narrow. If these commodities contain residues at the existing MRLs, an exceedance of the ARfD cannot be excluded as the calculated acute exposure accounts for 219%, 248% and up to 484% of the ARfD, respectively.

Furthermore, EFSA highlights that the current residue definitions for enforcement and risk assessment were considered in this assessment, in line with the terms of reference. However, during the peer review for the renewal of the approval of indoxacarb, additional metabolites were also included provisionally in the residue definition for risk assessment for processed commodities, for milk, poultry tissues and eggs pending additional information on their levels and their toxicological profile. The additional uncertainties associated with these data gaps may be particularly relevant for commodities for which a narrow safety margin was noted (basil and milk). For milk the calculated consumer exposure might be underestimated, given that the additional metabolite proposed for inclusion in the residue definition for risk assessment was identified in the metabolism study at up to 29% of the total radioactive residues. Regarding basil, there is a high level of uncertainty due to the absence of data on the magnitude and toxicity of residues potentially formed during processing, as well as on the consumption data of processed basil.

Conclusions and recommendations

Based on the assessment performed it is concluded that the existing MRLs covering CXLs/import tolerance for cranberries, potatoes, sweet corn, basil, dry beans, dry peas, peanuts, soya beans, cotton seed, tea, milk, ruminants, swine and poultry tissues and eggs are not expected to pose an unacceptable risk for consumers, and therefore risk managers may consider maintaining these MRLs. Moreover, the default LOQ of 0.01 mg/kg is sufficiently protective for the remaining commodities.

EFSA highlights that this conclusion was reached based on the calculations performed according to the internationally agreed methodology and the current residue definitions, demonstrating that the uses under consideration will not result in consumer intake exceeding the ARfD. However, a narrow safety margin was noted. Hence, if residues of indoxacarb occur in basil, cattle milk and meat (swine, bovine and sheep) at the relevant existing MRL value, the dietary exposure of certain consumers may exceed the ARfD under certain conditions (i.e. consumption of a large portion of the product without washing/peeling/processing which would lead to a reduction of the residues in the product). Risk managers should decide whether the safety margin of the exposure assessment based on the highest residue is sufficient, considering that residues in individual units/lot consumed at the proposed MRL might occur.

Moreover, during the peer review for the renewal of the approval of indoxacarb, additional metabolites which were not considered in this assessment, were included provisionally (pending additional information on their levels and their toxicological profile) in the residue definition for risk assessment for processed commodities, for milk, poultry tissues and eggs. Therefore, the additional uncertainties associated with these data gaps may need further attention by risk managers particularly for basil and milks for which a narrow safety margin was also noted.

Once additional data addressing the data gaps identified during the peer review would become available in the future, the conclusions from this assessment will need to be re-considered.

Furthermore, the information identified during the MRL Review as required for poultry tissue and eggs are still unavailable and therefore, they require further consideration by risk managers. In particular, these CXLs need to be confirmed by the following data:
