In accordance with Article 6 of Regulation (EC) No 396/2005, the evaluating Member State (EMS), the Netherlands, received an application from BASF SE to modify the existing maximum residue level (MRL) for the active substance kresoxim-methyl in leeks. In order to accommodate for the intended use of kresoxim-methyl, the Netherlands proposed to raise the value of existing MRL to 9 mg/kg. The Netherlands 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. According to EFSA, the data are sufficient to derive a MRL proposal of 10 mg/kg for the proposed use on leeks. An adequate analytical enforcement method is available to control the residues of kresoxim-methyl on the commodity under consideration. Based on the risk assessment results, EFSA concludes that the proposed use of kresoxim-methyl on leeks will not result in a consumer exposure exceeding the toxicological reference value and therefore is unlikely to pose a consumer health risk.
