Anthrax is a serious disease usually caused by Bacillus anthracis bacteria. It’s found naturally in soil around the world and commonly affects livestock and wild animals. People usually get sick with anthrax if they come in contact with infected animals or contaminated animal products. People can breathe in anthrax spores, eat food or drink water contaminated with spores, or get spores in a cut or scrape in the skin.

Livestock and wild animals can become infected when they breathe in, eat, or drink spores in contaminated soil, plants, or water. These animals can include cattle, sheep, goats, antelope, and deer.

Anthrax is rare in the United States. However, occasional outbreaks do happen in wild and domestic grazing animals such as cattle or deer. In the United States, veterinarians recommend yearly vaccination of livestock in areas where animals have had anthrax in the past.

Most people will never be exposed to anthrax. However, there are jobs, hobbies, and activities that can put some people at higher risk of exposure.
