The first part of the report considers general principles regarding the evaluation of veterinary drugs within the terms of reference of JECFA, including compounds without an ADI or MRL; recommendations on principles and methods in derivation of MRLs, including a new procedure for estimating chronic dietary intakes; the use of a spreadsheet-based procedure for the statistical evaluation of residue depletion data; a revised approach for the derivation of microbiological ADIs; and the Committee's review of and comments on documents provided by the Codex Committee on Residues of Veterinary Drugs. Summaries follow of the Committee's evaluations of toxicological and residue data on a variety of veterinary drugs: three antimicrobial agents (colistin, erythromycin, flumequine), two production aids (melengestrol acetate, ractopamine hydrochloride, an insecticide (trichlorfon (metrifonate)), and an anthelminthic (triclabendazole). In addition, the attempt by the Committee to use tylosin as an example to investigate if evaluations are possible based on published data in the absence of data submissions from sponsors is described. Annexed to the report is a summary of the Committee's recommendations on these drugs, including acceptable daily intakes and proposed maximum residue limits. 410 0$aTechnical report series (World Health Organization) ;$v909. 606 $aFood additives$xToxicology$vCongresses 606 $aFood additives$xAnalysis$vCongresses 606 $aFlavoring essences$xAnalysis$vCongresses 606 $aFood contamination$vCongresses 615 0$aFood additives$xToxicology 615 0$aFood additives$xAnalysis 615 0$aFlavoring essences$xAnalysis 615 0$aFood contamination 676 $a363.192 712 02$aWorld Health Organization. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910143507103321 996 $aEvaluation of certain food additives and contaminants$91989825 997 $aUNINA
