The Codex Committee on Residues of Veterinary Drugs in Food (CCRVDF) is meeting in Minneapolis, Minnesota, from August 26-30, 2013. We are writing to ask that the U.S. support language that would urge countries to prohibit the use of nine veterinary drugs, that in the US have been removed from, or not allowed on, the market due to human health concerns, particularly carcinogenicity and mutagenicity.
