veterinary Drug working group
The NACRW VDR WG is
launching a 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 below.
july 2021 virtual working group meeting
Annual meeting was held virtually in 2021
Monday, July 26, 2021
1:15 - 3:15 pm
Presentations (P1, P2, P3, P4) and Open Forum discussed the optimal MS-based analyte identification criteria. A collaborative study of multiple matrices and analytes is being planned to evaluate analyte identification criteria to minimize the rate of false positives and false negatives.

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.
