Nouws antibiotic test: Validation of a post-screening method for antibiotic residues in kidney

Anticipating the rise in ‘suspect’ samples caused by the introduction of a more sensitive screening test for the presence of antibiotic residues in slaughter animals, an additional microbial post-screening method was developed. The test comprises four antibiotic group specific test plates, optimized for the analysis of kidney and has been validated according to 2002/657/EC using fortified kidney samples. For each test plate activity profiles are presented, enabling a considerate choice of one or more representative component for each test plate. This information can be used to minimize validation efforts for further implementation of the test in routine field laboratories.
