2022 - 2026 collaborative study
Regulatory food laboratory participation is requested in an international collaborative project. The goal is to evaluate identification criteria using LC-MS (triple quadrupole and/or high resolution) for multi-veterinary drug residues analysis. For more information, see the Letter of Invitation.

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.
