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.
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.
Reviewed study parameters, discussed introductory letter and "Call for Participants"; began developing a list of international laboratories who might participate; prepare protocol for first round.
Discussed introductory letter and "Call for Participants"; began developing a list of official control international laboratories who might participate; prepare protocol for first round.
Draft introductory letter reviewed; added international, E.U. and U.S. labs to invitation list; reviewed website content, drafted content for Meeting at a Glance, reviewed collaborative study timeline, began preparing protocol for first round.
Finalize list of potential participants and letter advertising the study. Begin drafting protocol for 1st round of collaborative study. Approve abstract and agenda for July Working Group annual meeting.
