In December 2022, the LSU School of Veterinary Medicine was instrumental in diagnosing and treating several horses in Louisiana infected with a suspected toxin. The investigation revealed a much wider problem, as the culprit was alfalfa cubes infected with Clostridium botulinum type C, which causes botulism. The quick resolution of this issue would not have been possible without the combined efforts of farm owners and staff, LSU Vet Med, LADDL, LDAF, UC Davis, and the FDA.

Rose Baker, BVMS, DACVIM (LAIM), assistant professor of equine medicine, and Jonathan Roberts, DVM, director of the commercial feed program with LDAF, will discuss how they worked together to discover what was harming these horses.
