“Surprise!” – Anthrax, After Making its Comeback in Wyoming

Sep 13, 2024

Wyoming, we have a problem. 

Anthrax: A bacterial disease caused by Bacillus anthracis, which is a naturally occurring organism found throughout the world. The bacteria, which is spore-forming, can survive in the soil for DECADES. Meaning, outbreaks can occur sporadically at any time, typically after drought, then heavy rain.

Where? Carbon County, Wyoming. Between 50 and 60 head of cattle have died so far, and anthrax has been confirmed in multiple herds (plus one moose). Wyoming has not had any confirmed anthrax cases in its cattle herds since the 1970s. The diagnosis was confirmed by the Wyoming State Veterinary Laboratory on August 31. 

How? Once the bacterial spores are released, wild and domestic animals may become infected by breathing in or eating the spores from contaminated water, plants, or soil. Clinical signs of anthrax in livestock include difficulty breathing, weakness, fever, bloody feces, or sudden death. There is a vaccine available for both livestock and humans, to help prevent infection from the bacteria. 

Soundbite: “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.” — Dr. Hallie Hasel, Wyoming State Veterinarian
