New food safety initiatives in the Food and Drug Administration.

Concern over the presence of veterinary drug residues in food has been increasing world wide. Because of this concern the Food and Drug Administration's Center for Veterinary Medicine (CVM) has been involved on an international basis in efforts to develop food safety standards for veterinary drugs. The major thrust of the Codex Committee on Residues of Veterinary Drugs in Foods (CC/RVDF) has been to achieve international agreement on veterinary drugs issues. CVM is an active participant on this committee. The CC/RVDF has established a list of priority veterinary drugs that are, or that have the potential to cause trade problems as the result of public health concerns. Included in this list are anabolic hormones, chloramphenicol, sulfonamides, nitrofurans, nitroimidazoles, somatotropins, benzimidazoles and trypanocides. In the upcoming years, the CC/RVDF will work toward developing international maximum residue levels for these compounds. The evaluation of the toxicity of veterinary drug-bound residues is another area of international concern. In conjunction with the Bureau of Veterinary Medicine, Health and Welfare Canada, CVM is developing guidelines on biological models to demonstrate the safety of veterinary drug-bound residues. In working with veterinary drug regulators from other countries, CVM has new solutions to human food safety problems.
