Tuberculosis Testing

Tuberculosis testing is a federally regulated test that must be performed by an accredited veterinarian. The testing involves two appointments that are 72 hours apart. The veterinarian will have to inject the animal near the tail base and evaluate the injection site 72 hours later. Animals being tested must have official identification for record keeping.

What is Tuberculosis?
Tuberculosis (TB) is a contagious, infectious, bacterial respiratory disease of animals and humans. It usually presents as a chronic, debilitating disease but occasionally may present as an acute, rapidly progressive disease. There are a wide range of symptoms but can include coughing, weight loss, difficulty breathing, inappetence, etc. TB is spread by direct contact, inhalation of droplets expelled from infected lungs, and ingestion of contaminated feed or milk.
