FDA and AAFCO Sponsor Workshop

FDA Veterinarian Newsletter March/April 2003 Volume XVIII, No 2

FDA and the Association of American Feed Control Officials (AAFCO) recently sponsored a workshop dedicated to development of tests for detection of prohibited mammalian proteins in animal feed. The workshop, held in Tucson, Arizona, attracted more than a dozen domestic and international presenters along with an audience of approximately eighty. Drs. Dragan Momcilovic, CVM and Larry D’Hoostelaere, FDA Office of Regulatory Affairs (ORA), co-chaired the meeting.

Presenters from government including CVM, academia, and industry covered two general areas: introductory/general interest and specific approaches to test development. Reports on the latter showed that detecting protein by using immunological methods is the most favored approach followed by DNA analysis, and microscopy. The reports also suggested that different developers are at different stages of developing a test for detecting protein. While some speakers claimed that they have tests that are ready for use, others cautioned that significant technical challenges remain to be addressed before a successful test is developed.

Presentations from this workshop are available on the web at www.aafco.gov, under “meetings”.
