ABSTRACT
Under the pressure of an increasing number of drugs with fixed tolerance or maximum residue limits (MRLs), demands on methods to detect antimicrobial residues in edible animal products have changed markedly during recent decades (1). To satisfy these demands and prevent contaminated products from entering the food chain, many microbiological tests with sufficient detection sensitivity of as many analytes as possible in animal tissues, milk, eggs, honey, and fish have been developed or modified.
