Beta-lactam Antibiotics are among the most widely used antibiotics for the treatment of bacterial infections in cattle and therefore trace amounts are possible in the milk produced by a treated animal. The screening of Beta-lactam residues in milk is important due to the hypersensitivity of some individuals to these antibiotics and the emergence of antibiotic-resistant strains of bacteria. Randox Food Diagnostics provide an extremely reliable ELISA test platform for the detection of beta-lactam antibiotics in milk.
