Abstract
In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Belchim Crop Protection NV/SA submitted a request to the competent national authority in Hungary to modify the existing maximum residue levels (MRLs) for the active substance valifenalate in various crops. The data submitted in support of the request were found to be sufficient to derive MRL proposals for lettuces, tomatoes, aubergines, onions, shallots and garlic. Adequate analytical methods for enforcement are available to control the residues of valifenalate 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 long-term intake of residues resulting from the use of valifenalate according to the reported agricultural practices is unlikely to present a risk to consumer health. The short-term intake was not carried out since no acute reference dose (ARfD) is established for valifenalate. The reliable end points, appropriate for use in regulatory risk assessment are presented.Entities:
