Use of liquid chromatography-mass spectrometry in the analysis of residues of antibiotics in meat and milk.

The advent of affordable LC-MS systems has led to a massive increase in a number of publications describing quantitative methods for the analysis and confirmation of veterinary drug residues. The lack of volatility and thermal instability of many antibiotics makes LC-MS the method of choice for their analysis. In the review, analytical methods for the determination of residues of each of the major classes of antibiotics are presented.
