Outbreak Update

Louisiana Department of Agriculture and Forestry

Comments: The Louisiana Department of Agriculture & Forestry (LDAF), in cooperation with the U.S. Food and Drug Administration (FDA) and the California Animal Health & Food Safety Laboratory (CAHFS), has confirmed the presence of Clostridium botulinum type C in alfalfa hay cubes linked to the death of at least 20 horses in Louisiana. This incident, which has evolved into a multi-state epizootic of Equine Botulism linked to the same alfalfa hay cubes, has also been connected to at least 28 similar horse deaths in New Mexico, Texas, and Colorado, with many other horses becoming clinically ill. Equine Botulism is a condition caused from a bacterial toxin produced by Clostridium botulinum. In this incident, the condition was likely caused from direct ingestion of the toxin produced by the vegetative bacteria through contamination of the alfalfa hay cubes.
