Anthrax is most commonly found in soil and commonly affects animals such as cattle, sheep, goats, and horses. It is caused by a bacteria called Bacillus anthracis, which produces spores that can survive in the environment for a long period of time. Although anthrax is rare, it can spread through contact with infected animals or their products, such as wool, hides, or meat. Humans can also get sick from contact with contaminated animal products, or from breathing in the spores. In rare cases, anthrax can also be spread through contact with contaminated soil or water. If you think you may have been exposed to anthrax, it is important to seek medical attention right away.
