 Goals of the NACRW Veterinary Drugs Working Group 

  • To identify Multi-Residue/Multi-Class Vet Drug Residue Methods (> 100 analytes) that would meet the needs of regulators. 
  • The NACRW Veterinary Drugs Working Group (VDWG) proposes to investigate veterinary drug screening methods which utilize LC-MS instrumentation to detect the presence of one or more regulated compounds at levels below the food safety relevant defined maximum levels.
  • Current project: VDR-WG to draft and review the process and agenda for a Collaborative Study in several rounds identifying methods and criteria relevant for goal described above.
