Rapid control systems for veterinary drug residues in food producing animals

Abstract

The aim was to develop rapid systems which could be used to test for the presence of veterinary drug residues in food producing animals. Body fluid samples are most suitable for rapid testing systems so as to avoid the lengthy residue extraction procedures required for tissue samples. Urine was analysed for sulphamethazine, a licensed antimicrobial, and for chlorotestosterone, a prohibited growth promoting agent, as models to demonstrate the different approaches.
