Tuberculosis in Sheep & Goats

 
What is Tuberculosis?
Tuberculosis (TB) is a chronic disease which, in sheep and goats, can be caused by mycobacterium bovis or mycobacterium tuberculosis.
 
How is TB transmitted?
TB is transmitted through both unpasteurized milk and respiratory secretions (coughing, sneezing, etc).
 
What are the signs of infection?
Symptoms are respiratory in nature and include coughing along with weight loss.
 
Can TB infect humans?
Yes. If you have concerns about possible exposure contact your primary care physician. Raw milk, which hasn’t gone through the pasteurization process to destroy bacteria, retains the possibility of transmission.
 
What can I do to prevent TB in my herd/flock?
Buy animals from known sources.  If you are purchasing from out of state, ensure that all animals meet the import requirements for sheep and goats entering Idaho.
 
What are the TB testing requirements?
There is an annual testing requirement for all participants in the Raw Milk Program, and additional testing can be required at any time.
 
Who do I contact for TB testing?
Contact your veterinarian – TB tests can only be done by USDA accredited veterinarians.  If they have a suspect result, they are required to contact USDA or Animal Industries to coordinate the mandatory additional testing.
 
What will testing cost me?
Contact your veterinarian for their TB testing rates.
 
What do I do if my flock/herd is positive?
Contact USDA at (208) 373-1620.  They will instruct you on procedures for positive flocks/herds.
 
Tuberculosis is a reportable disease in Idaho.
