With strict regulations and government controls worldwide, the monitoring of
animal drug residues is becoming increasingly complex and demanding. The risk
of failing to comply with legally permitted maximum limits can affect consumer
health. For this reason, accurate results of residue levels in animal products are
needed. International food safety authorities outline the concept of reference
method criteria in which minimum requirements of analytical methods used in
the analysis of veterinary drug residues, being screening or confirmatory, were
described. In this document, the most important analytical methods used in the
screening of antimicrobial and some other veterinary drug residues are described.
