Anthrax has been confirmed in multiple beef herds in Carbon County, Wyoming, by the Wyoming State Veterinary Laboratory. It led to the deaths of 50 to 60 cattle and is the first anthrax case in Wyoming cattle since the 1970s. A dead moose found on September 3 also tested positive for anthrax, the first case in Wyoming wildlife since 1956.

Anthrax, caused by Bacillus anthracis, can persist in soil for years. It often emerges after droughts followed by rain. Infected animals show symptoms like sudden death, difficulty breathing, fever, and bloody diarrhea.

The Wyoming Livestock Board and veterinarians are working to contain the outbreak through carcass disposal and vaccination. The anthrax vaccine is considered highly effective. The Wyoming Game and Fish Department advises against approaching dead animals. The situation is being monitored to prevent further outbreaks and human exposure.
