Anthrax in Wyoming confirmed in multiple cattle herds

Both the WSVL and private veterinarians were essential in the diagnosis of anthrax impacting several herds in the region.

Anthrax is a bacterial disease caused by Bacillus anthracis , a naturally occurring organism with worldwide distribution. The spore-forming bacteria may survive in the soil for years to decades, resulting in sporadic outbreaks which usually occur after periods of drought followed by heavy rain.

Domestic and wild animals may become infected when they breathe or ingest spores in contaminated soil, plants, or water. Clinical signs of anthrax in livestock include sudden death, weakness, staggering, difficulty breathing, fever, and bloody diarrhea.

“Multiple state agencies and private veterinarians responded quickly following the anthrax diagnosis by the Wyoming State Veterinary Laboratory. Protecting animal and human health is critical upon diagnosis of a zoonotic disease,” said Dr. Hallie Hasel, Wyoming State Veterinarian. “The Wyoming Livestock Board will continue working with producers and private veterinarians to reduce further spread and limit human exposure through recommendations for carcass disposal and vaccination. Anthrax vaccine is approved for multiple livestock species and highly effective.”
