Reasoned opinion on the review of the existing maximum residue levels (MRLs) for asulam according to Article 12 of Regulation (EC) No 396/2005
Considering that the use of asulam is no longer authorised within the EU (authorisations for emergency situations in plant protection granted in application of Article 53 of Regulation (EC) No 1107/2009 are not considered in the context of this Reasoned Opinion), that no CXLs are available for this active substance and that no uses authorised in third countries were notified to the RMS, residues of asulam are not expected to occur in any plant commodity.
Nevertheless, primary crop metabolism of asulam was investigated for leafy vegetable (spinach). Parent remains the major residues in leafy crops, but is likely to conjugate into asulam malonyl (also during the storage of samples).
Therefore, the most relevant residue for enforcement against a potential illegal use on plant (leafy crops) should be the sum of asulam and asulam malonyl, expressed as asulam. There are indications that asulam and asulam malonyl can be enforced with an LOQ of 0.05 mg/kg for each compound in plant commodities.
Reasoned opinion on the review of the existing maximum residue levels (MRLs) for flumioxazin according to Article 12 of Regulation (EC) No 396/2005
Primary crop metabolism of flumioxazin was investigated following pre-mergence soil application on fruits and fruiting vegetables and on pulses and oilseeds. Metabolism following foliar application on sugar cane was also investigated and the relevant residue for enforcement and risk assessment in all commodities of plant origin is defined as flumioxazin only. Analytical methods for enforcement of the residue definition are available in foods of plant origin with an LOQ of 0.02 mg/kg in high water content and dry commodities and an LOQ of 0.05 mg/kg in acidic and high fat content commodities.
Regarding the magnitude of residues in all crops reported by the RMS, at least one GAP was supported by a sufficient number of supervised residue trials, which allowed EFSA to estimate the expected residue concentrations in all the relevant plant commodities and to derive appropriate MRLs, except for onions where a tentative MRL is derived.
Reasoned opinion on the review of the existing maximum residue levels (MRLs) for ethoxyquin according to Article 12 of Regulation (EC) No 396/2005
Primary crop metabolism of ethoxyquin was investigated following post harvest application on pears, hereby covering group of fruits and fruiting vegetables.
According to Article 12 of Regulation (EC) No 396/2005, the European Food Safety Authority (EFSA) has reviewed the Maximum Residue Levels (MRLs) currently established at European level for the pesticide active substance ethoxyquin. Although this active substance is no longer authorised within the European Union, an MRL was established by the Codex Alimentarius Commission (CXL). Based on the assessment of the available data, EFSA assessed the CXL, and a consumer risk assessment was carried out. The CXL was found not to be adequately supported by data and a possible risk to consumers was identified. Hence, further consideration by risk managers is needed.
