Book excerpt: This report represents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of residues of certain veterinary drugs in food and to recommend maximum levels for such residues in food. The first part of the report considers general principles regarding the evaluation of residues of veterinary drugs within the terms of reference of the Joint FAO/WHO Expert Committee on Food Additives (JECFA). It covers topics such as the parallel review process; estimation of dietary exposure to veterinary drug residues; a risk-based decision tree approach for safety evaluation; assessment of the potential effects of residues on the human intestinal microbiome. Summaries follow the Committee’s evaluations of toxicological and residue data on a variety of veterinary drugs: two antiparasitic agents (imidacloprid, ivermectin) and one coccidiostat (nicarbazin). Additionally, further evaluation of the parasiticide selamectin is included as part of a pilot in support of the proposed parallel review process. Annexed to the report is a summary of the Committee’s recommendations on these drugs, including acceptable daily intakes and proposed maximum residue limits.
