End-to-end workflow for quantitative screening of multiclass, multiresidue veterinary drugs in meat

Veterinary drugs are commonly used to improve the growth and health outcomes of farm animals. Improper use of vet drugs in animal farming can result in the accumulation of these drugs in animal-derived foods, causing adverse effects to consumers. Global regulations define limits for vet drugs in food of animal origin to protect public health. As a gold standard for chemical quantitation, triple quadrupole LC/MS (LC/MS/MS) is a widely accepted technique for this analysis. To streamline day-to-day operation, a comprehensive workflow has been developed for the accurate and reliable analysis of >200 multiclass veterinary drugs in various animal-origin food matrices using LC/MS/MS.
