Background:
The Beta-lactam ring is part of the core structure of several antibiotic families, the principal ones being the penicillins, cephalosporins, carbapenems, and monobactams, which are, therefore, also called beta-lactam antibiotics. Nearly all of these antibiotics work by inhibiting bacterial cell wall biosynthesis. The detection of veterinary drug residues such as beta-lactams in raw milk is of great concern for the dairy industry because of the potential interfering and adverse effects of antibiotic residues frequently found in raw milk.
