Abstract

In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Syngenta Crop Protection AG submitted a request to the competent national authority in Greece to modify the existing maximum residue levels (MRLs) for lambda‐cyhalothrin in celeries, fennel and rice. The data submitted in support of the request were found to be sufficient to derive tentative MRL proposals for the concerned crops. They are tentative as formally the general data gap identified in the MRL review for further investigations of the toxicological properties of the compounds formed under sterilisation conditions has not yet been addressed. Adequate analytical enforcement methods are available to control the residues of lambda‐cyhalothrin in the commodities under consideration. Based on the risk assessment results, EFSA concluded that the short‐term and long‐term intake of residues resulting from the uses of lambda‐cyhalothrin according to the reported agricultural practices is unlikely to present a risk to consumer health. The consumer risk assessment presented might need to be reconsidered in the light of the confirmatory data requested following the renewal of the approval and the review of the existing MRLs.

Summary

In accordance with Article 6 of Regulation (EC) No 396/2005, Syngenta Crop Protection AG 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 lambda‐cyhalothrin. 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 3 October 2016. The EMS proposed to raise the existing MRLs for lambda‐cyhalothrin in various crops.

EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation. EFSA identified data gaps which needed further clarification, which were requested from the EMS. Since missing information was still identified for specific parts of the application, only the proposed uses on celeries, fennels and rice were taken forward. Request to modify MRLs on tree nuts and pears was not supported any longer in the framework of this MRL application.

Based on the conclusions derived by EFSA in the framework of the original approval and its renewal, the review of the existing MRLs for lambda‐cyhalothrin with its revisions and the additional data provided by the EMS in the framework of this application, the following conclusions were derived.

The metabolism of lambda‐cyhalothrin in primary and in rotational crops was sufficiently investigated in different crop category groups. Studies investigating the effect of processing on the nature of lambda‐cyhalothrin (hydrolysis studies) demonstrated that the active substance was stable under pasteurisation and baking/brewing and boiling but extensively degraded under sterilisation conditions, forming degradation products Ia, IV and gamma‐lactone.

In the framework of the MRL review, based on the results of the metabolism studies, the hydrolysis studies, the capability of the currently available enforcement analytical methods and taking into account that analytical methods do not allow to discriminate between lambda‐ and gamma‐cyhalothrin, the residue definitions for enforcement and risk assessment applicable to all plant commodities have been set as ‘lambda‐cyhalothrin (includes gamma‐cyhalothrin) (sum of R,S‐ and S,R‐isomers)’. The residue definition was set on provisional basis for processed products, pending the assessment of further data investigating the toxicological properties of the compounds formed under conditions simulating sterilisation. These residue definitions are considered appropriate also for the crops assessed under this application.

Sufficiently validated analytical methods are available to quantify residues of lambda‐cyhalothrin 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 (limit of quantification (LOQ)) in all plants, but do not allow distinguishing the different isomers of lambda‐cyhalothrin.

The available residue trials are sufficient to derive MRL proposals of 0.2 mg/kg for celeries and rice and 0.3 mg/kg for fennel.

Studies investigating the magnitude of lambda‐cyhalothrin residues in processed celeries, fennel and rice were not submitted. Processing factors have been previously derived for washed, cooked and canned beans with pods and canned tomatoes, for possible extrapolation to the two vegetables assessed, and for polished rice and rice bran. A reduction of residues of the active substance and of compound Ia was observed in these studies. The degradation products compound IV and gamma‐lactone were analysed for in canned beans and tomatoes and they were not found (< 0.01 mg/kg). Supposing that the processing studies with beans and tomatoes are representative for the expected degradation in processed celery and fennel, it may be reasonably assumed that quantifiable residues of compounds Ia, IV and gamma‐lactone are not present in processed celeries and fennel. Taking into account that the common processing practice for rice is cooking, and that lambda‐cyhalothrin was concluded to be stable under conditions representative for boiling, studies addressing the magnitude of residues in cooked rice were not requested at this stage. However, the general data gap identified in the framework of the MRL review for investigation of the toxicological properties of compounds Ia, IV and gamma‐lactone still has to be addressed.

Based on the available information on the magnitude of residues, EFSA concluded that significant residue levels are unlikely to occur in rotational crops provided that the active substance is used according to the proposed good agricultural practices (GAPs).

As the rice straw and bran/pollard are used as feed products, a potential carry‐over into food of animal origin was assessed. However, the contribution of lambda‐cyhalothrin residues arising from the proposed use in rice feed items does not trigger a revision of the existing MRLs for commodities of animal origin.

The toxicological profile of lambda‐cyhalothrin was assessed in the framework of the EU pesticides peer review for renewal of the approval and the data were sufficient to derive an acceptable daily intake (ADI) of 0.0025 mg/kg body weight (bw) per day and an acute reference dose (ARfD) of 0.005 mg/kg.

The consumer risk assessment was performed with revision 2 of the EFSA Pesticide Residues Intake Model (PRIMo). The estimated long‐term intake was in the range of 7–61% of the ADI. The estimated short–term exposure conducted according to the currently agreed methodology did not exceed the ARfD for any of the crops under assessment.

EFSA concluded that the proposed use of lambda‐cyhalothrin on celeries, fennel and rice will not result in a consumer exposure exceeding the toxicological reference values and therefore is unlikely to pose a risk to consumers’ health. The consumer risk assessment presented has to be regarded as provisional and might need to be reconsidered in the light of the confirmatory data requested following the renewal of the approval and the review of the existing MRLs for lambda‐cyhalothrin.

EFSA derived tentative MRL proposals as reported in the summary table below; they are tentative as formally the general data gap identified in the framework of the MRL review requesting further investigations of the toxicological properties of compounds Ia, IV and gamma‐lactone formed under sterilisation conditions has not yet been addressed. A risk management decision is required whether it is appropriate to take over the tentative MRLs in the MRL legislation. Risk managers should take into account that the MRL application was made after the publication of the EFSA reasoned opinion where this data gap was identified but before the general data gap was taken over in the MRL legislation.

Full details of all end points and the consumer risk assessment can be found in Appendices BD.

Assessment

The European Food Safety Authority (EFSA) received an application to modify the existing maximum residue levels (MRLs) of lambda‐cyhalothrin for celeries, fennel and rice. The detailed description of the intended uses of lambda‐cyhalothrin, which are the basis for the current MRL application, is reported in Appendix A.

Lambda‐cyhalothrin is the ISO common name for (R)‐α‐cyano‐3‐phenoxybenzyl (1S)‐cis‐3‐[(Z)‐2‐chloro‐3,3,3‐trifluoropropenyl]‐2,2‐dimethylcyclopropanecarboxylate and (S)‐ α‐cyano‐3‐phenoxy‐benzyl (1R)‐cis‐3‐[(Z)‐2‐chloro‐3,3,3‐trifluoropropenyl]‐2,2‐dimethylcyclopropanecarboxylate (IUPAC). It represents a 1:1 mixture of two of the four components of the insecticide cyhalothrin: the R,S‐ and the S,R‐isomers. These two isomers are not distinguishable with laboratory analytical methods and the isomer S,R alone is the active substance gamma‐cyhalothrin, which is also approved for use in plant protection products. The chemical structures of the active substances and its main metabolites are reported in Appendix E.

Lambda‐cyhalothrin was included in Annex I to Directive 91/414/EEC on 1 January 2002 by Commission Directive 2000/80/EC1 and is deemed to be approved under Regulation (EC) No 1107/2009 in accordance with Commission Implementing Regulation (EU) No 540/20112. The approval has been renewed by Commission Implementing Regulation (EU) 2016/1463 which entered into force on 1 April 2016. The representative uses evaluated in the peer review for renewal were foliar spraying applications on wheat, potato, plum, peach and tomato. The renewal assessment report (RAR) has been peer reviewed by EFSA (2014b). Sweden acted as the rapporteur member state (RMS) in both the original and renewal approval procedures. Lambda‐cyhalothrin was approved for the use as an insecticide, but the applicant was requested to submit confirmatory information to the Commission, the Member States and EFSA by 1 April 2018.4 The peer review of the confirmatory data assessment has not yet been initiated. Lambda‐cyhalothrin has been included in the list of candidates for substitution.

The European Union (EU) MRLs for lambda‐cyhalothrin are established in Annex II of Regulation (EC) No 396/2005. The review of the existing MRLs for lambda‐cyhalothrin according to Article 12 of Regulation (EC) No 396/2005 was performed in 2014 (EFSA, 2014a), revised in 2015 (EFSA, 2015) taking into account the lower toxicological end points set during the EU pesticides peer review renewal (European Commission, 2015b) and reconsidered in the light of the uses of gamma‐cyhalothrin of potential concerns for the consumers (EFSA, 2017). The MRL modifications recommended by EFSA have been implemented in the MRL legislation by Regulation (EU) 2018/9605. For most of the plant and animal commodities for which MRLs were proposed by EFSA, including those recommended for celeries, fennel and rice, certain information was missing (data gaps). Footnotes were included in the Regulation (EU) 2018/9606, requesting additional information to be provided by 6 July 2020.

In accordance with Article 6 of Regulation (EC) No 396/2005, Syngenta Crop Protection AG submitted an application to the competent national authority in Greece (evaluating Member State (EMS)) to modify the existing MRLs for the active substance lambda‐cyhalothrin. 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 3 October 2016. The EMS proposed to raise the existing MRLs for lambda‐cyhalothrin in various crops. EFSA assessed the application and the evaluation report as required by Article 10 of the MRL regulation. EFSA identified data gaps which needed further clarification, which were requested from the EMS. Since missing information was still identified for specific parts of the application, only proposed uses on celeries, fennels and rice were taken forward. Request to modify MRLs on tree nuts and pears was not supported any longer in the framework of this MRL application.

EFSA has based its assessment on the evaluation report submitted by the EMS and revised in 2018 (Greece, 2016), the RAR and its final addendum prepared under Regulation (EU) No 1141/20107 (Sweden, 2013, 2014), the revised Commission review report on lambda‐cyhalothrin (European Commission, 2015b), the conclusion on the peer review of the pesticide risk assessment of the active substance (EFSA, 2014b) and the reasoned opinions related to the review of the existing MRLs for lambda‐cyhalothrin (EFSA, 2014a, 2015, 2017).

For this application, the data requirements established in Regulation (EU) No 544/2011 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, 2015a; OECD, 2011, 2013). 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 546/20118.

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

The evaluation report submitted by the EMS as revised in 2018 (Greece, 2016) 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.

1. Residues in plants

1.1. Nature of residues and methods of analysis in plants

1.1.1. Nature of residues in primary crops

The metabolism of lambda‐cyhalothrin in primary crops after foliar and local applications has been previously investigated in fruit crops, leafy crops, pules/oilseeds and cereals. Lambda‐cyhalothrin was the predominant residue (37–95% total radioactive residue (TRR)) while compound Ia was identified as a significant metabolite in soya bean and cotton leaves only (17–25% TRR).

Based on the chiral analysis on residue trial samples assessed in the framework of the EU pesticides peer review renewal, EFSA concluded that the impact of the change in the ratio of the isomers on the toxicological burden the consumer is exposed to, was of low concern (EFSA, 2014a,b).

For the crops under assessment, belonging to the crop groups of cereals and leafy crops, EFSA concluded that the metabolism of lambda‐cyhalothrin was sufficiently investigated.

1.1.2. Nature of residues in rotational crops

The crops under consideration may be grown in rotation. The metabolism of lambda‐cyhalothrin in rotational crops has been previously investigated (EFSA, 2014a,b). Parent compound extensively degraded in the edible parts of the rotated crops and was only detected in negligible proportions in wheat straw (< 1% TRR). Compound Ia was the major residue (34–52% TRR).

For the crops under assessment, EFSA concluded that the metabolism of lambda‐cyhalothrin in rotational crops was sufficiently investigated.

1.1.3. Nature of residues in processed commodities

Lambda‐cyhalothrin remained stable under hydrolytic conditions representative of pasteurisation and baking, brewing and boiling (82–91% TRR), while a significant degradation occurred under conditions simulating sterilisation. Hydrolytic cleavage of the parent molecule to compound Ia, compound IV and gamma‐lactone was noted. Since the toxicity of these compounds has not been sufficiently addressed, a general data gap was identified in the framework of the MRL review for investigation of the toxicological properties of compounds Ia, IV and gamma‐lactone formed under sterilisation conditions (EFSA, 2014a).

For all crops which may be consumed after processing that were assessed in the MRL review, a general data gap was implemented in the EU legislation by Regulation (EU) 2018/960 published in the Official Journal of the European Union on 6 July 2018 as confirmatory data to be submitted by 6 July 2020. It is noted that this MRL application was submitted to the national competent authority in Greece before Regulation (EU) 2018/960 has been published.

1.1.4. Methods of analysis in plants

The multi‐residue analytical method also known as the QuEChERS method (Quick, Easy, Cheap, Effective, Rugged, and Safe) using gas chromatography–mass spectrometry detection (GC–MS) and the multi‐residue method using liquid chromatography–tandem mass spectrometry (LC–MS/MS) were considered sufficiently validated for monitoring lambda‐cyhalothrin in plant commodities at the limit of quantification (LOQ) of 0.01 mg/kg in high water content, high oil content, high acidic content and dry commodities (EFSA, 2014a,b, 2015). It is noted that the analytical methods available do not allow distinguishing the different isomers of lambda‐cyhalothrin.

EFSA concluded that sufficiently validated analytical methods are available for enforcing the proposed MRLs for lambda‐cyhalothrin in the crops under assessment.

1.1.5. Stability of residues in plants

Studies on the storage stability of lambda‐cyhalothrin under frozen conditions were assessed in the framework of the EU pesticides peer review renewal and the MRL review (EFSA, 2014a,b).9 It was demonstrated that for the crops assessed in the framework of this MRL application, residues are stable for 26 months when stored ≤ –18°C.

1.1.6. Proposed residue definitions

In the framework of the MRL review, based on the results of the metabolism studies, the hydrolysis studies and the capability of the currently available enforcement analytical methods (see Section 1.1.4), the residue definition for enforcement and risk assessment in all plants was set as ‘lambda‐cyhalothrin (includes gamma‐cyhalothrin) (sum of R,S‐ and S,R‐isomers)’. For processed commodities the same residue definitions as for unprocessed products were proposed on a provisional basis, pending the assessment of further toxicological data investigating the toxicological properties of degradation products formed under conditions simulating sterilisation conditions, i.e. compounds Ia, IV and gamma‐lactone (EFSA, 2014a, 2015).

The residue definition for enforcement in Regulation (EC) No 396/2005 is identical as the above‐mentioned. It is noted that the definition is not specific to lambda‐cyhalothrin and covers also residues arising from the use of gamma‐cyhalothrin (EFSA, 2017).

1.2. Magnitude of residues in plants

1.2.1. Magnitude of residues in primary crops

Celeries: Based on the results of four good agricultural practice (GAP)‐compliant residue trials conducted in northern Europe with lambda‐cyhalothrin (trials performed in two seasons), EFSA derived a MRL proposal of 0.2 mg/kg for celeries.

Fennels: Based on the results of four overdosed residue trials on celeries conducted in southern Europe (trials performed in two seasons), and after having proportionally scaled the results to the nominal application rate intended for fennels, EFSA derived a MRL proposal of 0.3 mg/kg for fennels by extrapolation. The proposed extrapolation is in line with the EU guidance document (European Commission, 2015a).

Rice: Based on the results of eight GAP‐compliant residue trials conducted in Italy (trials performed in two seasons), where lambda‐cyhalothrin was applied twice on rice before or after flooding rice fields, EFSA derived a MRL of 0.2 mg/kg for rice (grain).

In addition, the applicant provided residue trials investigating the magnitude of residues in rice straw, which was used for the dietary burden calculation (see Section 2).

According to the EMS, the analytical methods used to analyse the samples of the residue trials have been sufficiently validated and residue data were valid with regard to storage stability (Greece, 2016).

1.2.2. Magnitude of residues in rotational crops

Based on the results of the confined rotational crop metabolism studies, which were conducted at a maximum total application rate significantly higher (about 13N) than the intended rates on the crops under assessment (maximum 34.5 g/ha), significant residue levels (< 0.01 mg/kg) are not expected in the edible parts of the rotated crops, provided that lambda‐cyhalothrin is applied in compliance with the intended GAPs.

This conclusion was confirmed by rotational crop field trials conducted at a total dose rate of 500 g/ha which resulted in residues of lambda‐cyhalothrin and compound Ia below the LOQ in the edible parts at 30 and 60 day plant‐back intervals (EFSA, 2014b).

1.2.3. Magnitude of residues in processed commodities

No new processing studies were submitted in this MRL application. Considering the high toxicity of the active substance and the insufficient information on the toxicological proprieties of the compounds formed during conditions representative of sterilisation, the magnitude of residues in processed products that may undergo heating by processing shall in principle be addressed.

For celeries/fennels, the applicant proposed to consider the processing factors (PFs) derived for washed, cooked and canned beans with pods derived in the framework of the EU pesticides peer review renewal and the MRL review revisions (EFSA, 2014a,b, 2015). In this study, all samples were analysed for the parent compound and the degradation product Ia. The processing studies on beans were conducted at about 8N or 13N the dose rate of the intended GAPs on celeries and fennel, respectively, leading to residues up to 0.26 mg/kg for lambda‐cyhalothrin and 0.04 mg/kg for compound Ia in unprocessed beans.10 Overall, a reduction of residues (parent and compound Ia) was seen in the processed products (including the intermediate processed products like washed and cooked beans) compared with the raw agricultural commodity. In the processed products, compound Ia accounted for up to 0.028 mg/kg in cooked beans and 0.017 mg/kg in sterilised beans. Canned beans were also analysed for IV and gamma‐lactone and residues were not found (< 0.01 mg/kg) following sterilisation (Sweden, 2013).

Additionally, the applicant referred to processing studies on tomatoes that demonstrated that residues of parent lambda‐cyhalothrin and compounds Ia, IV and gamma‐lactone were below the LOQ (< 0.01 mg/kg) in sterilised canned tomatoes, while the concentration of lambda‐cyhalothrin in unprocessed tomatoes accounted for 0.11 mg/kg11 (Sweden, 2013; EFSA, 2014b).

According to OECD guidance document, processing studies in beans are representative for all types of canned vegetables and therefore results on beans can be extrapolated to the other commodities of this type (OECD, 2008). Assuming that these two crops, when not eaten raw, will undergo processing like cooking and canning comparable with the conditions investigated in the processing studies with beans and tomatoes, it may be reasonably assumed that residues of compound Ia, IV and gamma‐lactone are not present in quantifiable concentrations.

For rice, PFs were derived from one processing study, investigating residues in polished rice, hulls and bran (FAO, 2008). The study showed a significant reduction of residues of lambda‐cyhalothrin in polished (white) rice and bran. Studies to investigate the effect of heating on the magnitude of residues in rice are not available. Taking into account that the common processing practice for rice is cooking and that lambda‐cyhalothrin was concluded to be stable under conditions representative for boiling (see Section 1.1.3), studies addressing the magnitude of residues in cooked rice were not requested at this stage.

It should be highlighted that the general data gap identified in the framework of the MRL review for investigation on the toxicological properties of compounds Ia, IV and gamma‐lactone still needs to be addressed. Pending the confirmation of the residue definition for processed products, further investigation on processed commodities may need to be generated.

1.2.4. Proposed MRLs

EFSA concluded that sufficient information was provided to calculate a MRL proposal of 0.2 mg/kg for celeries and rice and 0.3 mg/kg for fennels. The MRL proposals shall be regarded as tentative; the general data gap identified in the framework of the MRL review has not yet been addressed (see Section 1.1.3).

2. Residues in livestock

Rice straw and rice by‐products such as rice bran/pollard can be used as feed items in livestock. The most recent livestock dietary burden calculation was conducted in the framework of the review of MRLs under Article 12 of Regulation (EC) No 396/2005, where EFSA calculated the dietary intake of livestock taking into account the authorised EU uses of lambda‐cyhalothrin (EFSA, 2015); the calculation was performed according to the methodology described in the previously used European guidance document (European Commission, 1996). The maximum dietary burden for dairy and beef cattle was 0.89 and 1.39 mg/kg dry matter (DM), respectively, for poultry 0.17 mg/kg DM and for pigs 0.52 mg/kg DM. The EU MRLs for muscle, fat, liver and kidney were derived from the existing Codex MRLs (CXL), considering the maximum dietary burden of 6.2 mg/kg DM for beef cattle (FAO, 2008).

In the framework of the current application, the dietary burden was re‐calculated in accordance with the OECD guidance document (OECD, 2013) which is the methodology applicable at the date of submission of the MRL application. The input values are summarised in Appendix D.1. The results of the calculations are presented in Appendix B.3. Comparing the results obtained with the new methodology and the results reported in the previous EFSA opinion (EFSA, 2015), it became evident that different methodology had an impact on the result, with a slightly changed dietary exposure for the different animal species included in both models in the calculations using the OECD methodology. The contribution residues in rice straw and bran/pollard are not significantly changing the livestock intakes.

Thus, EFSA concluded that the intended use on rice will not trigger a revision of the existing MRLs for commodities of animal origin.

3. Consumer risk assessment

The consumer risk assessment was performed with revision 2 of the EFSA Pesticide Residues Intake Model (PRIMo). This exposure assessment model contains the relevant European food consumption data for different subgroups of the EU population12 (EFSA, 2007).

The estimated exposure was then compared with the toxicological reference values derived for lambda‐cyhalothrin during the EU pesticides peer‐review renewal process (European Commission, 2015b).

The most recent long‐term exposure assessment performed by EFSA (2017) was updated with the median residue value (STMR) derived for celeries, fennel and rice derived from the residue trials submitted with this application. The acute exposure assessment was performed only with regard to the use of lambda‐cyhalothrin on the commodities under consideration assuming the consumption of a large portion of the food item as reported in the national food surveys and considering the highest residue (HR) level for celeries and fennel and the STMR for rice. The input values used for the dietary exposure calculation are summarised in Appendix D.

No long‐term and short‐term consumer intake concerns were identified for any of the European diets incorporated in the EFSA PRIMo. The total chronic calculated intake accounted for up to 61% of the acceptable daily intake (ADI) (WHO Cluster diet). The contribution of the residues on the crops under consideration to the total exposure accounted for a maximum of 1.3% of ADI (rice).

The expected short‐term exposure calculated according to the internationally agreed methodology described above did not exceed the toxicological reference value derived for lambda‐cyhalothrin. It should be highlighted that the safety margin to the acute reference dose (ARfD) is narrow for celeries (82.6% of the ARfD). It is expected that the exposure is slightly lower, if celeries are consumed after cooking, leading to a reduction of residues in the processed product.

4. Conclusion and Recommendations

The data submitted in support of the request were found to be sufficient to derive tentative MRL proposals for celeries, fennel and rice; they are tentative as formally the general data gap identified in the framework of the MRL review requesting further investigations of the toxicological properties of compounds Ia, IV and gamma‐lactone formed under sterilisation conditions has not yet been addressed. Based on the risk assessment results, EFSA concluded that the short‐term and long‐term intake of residues resulting from the uses of lambda‐cyhalothrin according to the reported agricultural practices is unlikely to present a risk to consumer health. The consumer risk assessment presented might need to be reconsidered in the light of the confirmatory data requested following the renewal of the approval and the review of the existing MRLs.

A risk management decision is required whether it is appropriate to take over the tentative MRLs in the MRL legislation. Risk managers should take into account that the MRL application was made after the publication of the EFSA reasoned opinion where this data gap was identified (EFSA, 2014a, 2015) but before the general data gap was published in the MRL legislation.

The calculation of the long‐term exposure (chronic exposure) is based on the mean consumption data representative for 22national diets collected from MS surveys plus one regional and four cluster diets from the WHO GEMS Food database; for the acute exposure assessment the most critical large portion consumption data from 19 national diets collected from Member States surveys is used. The complete list of diets incorporated in EFSA PRIMo is given in its reference section (EFSA, 2007).
