End of Project ReportBound residues of veterinary drugs have been recognised as an important aspect of food safety particularly (a) where such residues may persist for long periods after withdrawal of the drug treatment and (b) where the bound residues may be released, during digestion of edible tissues, in biologically active forms. Residues bound to proteins are not extractable by the conventional solvent extraction procedures for residue determination. Procedures for the release of bound residues from proteins, identification of their chemical structure, and determination of the amount of bound residues in edible tissues are required.EC-AIR programme (Project No. AIR2-CT93-0860
