(4)For oxadixyl temporary MRLs were set by Regulation (EU) No 592/2012note for parsley, celeries and the group of lettuces and salad plants until 31 December 2014, to address an unavoidable cross-contamination that affected untreated crops and which was due to the presence of residues of oxadixyl in soil. Commission Regulation (EU) 2016/46note extended the validity of those MRLs until 19 January 2018 in view of the persistence of that active substance in soil. The Authority and food business operators submitted recent monitoring data showing that residues of oxadixyl no longer occur at levels above the relevant LOD.
