Anthrax: Vaccination Considerations

Anthrax is caused by bacteria, Bacillus anthracis, which has the ability to form very resistant spores in the soil. These spores can remain viable for many years on pasture, and become reactivated when the right environmental conditions exist. Fortunately for cattle producers, losses due to anthrax can be prevented through use of a vaccine that has proven its effectiveness through the years.
