Vet-LIRN – The Veterinary Laboratory Investigation and Response Network (Vet-LIRN) is managed by FDA's Center for Veterinary Medicine. The primary objective of Vet-LIRN is to promote human and animal health by partnering with over 40 state and university veterinary diagnostic laboratories.  Vet-LIRN laboratories help FDA investigate potential adverse events affecting the nation’s food or animal feed supply by conducting testing of veterinary products, animal feeds or diagnostic samples.  Vet-LIRN laboratories maintain preparedness by optimizing and harmonizing testing methods, as well as conducting limited surveillance exercises and participating in network proficiency tests.  For more information on Vet-LIRN please see the following website:
