Tuberculosis Prevention and Control

Information about how to prevent and control further spread of Tuberculosis.

In livestock, bovine TB can be controlled within an affected herd through regular testing and slaughter of any single animal that tests positive until the entire herd tests negative for this disease. However, because there is no method available to ensure that bovine TB has been eliminated from an affected herd, APHIS recommends herd depopulation.

APHIS stresses that one of the most important factors is the realization that TB has not been eradicated in the United States. The disease will continue to be a threat until the last infected animal has been destroyed. Therefore, it is recommended that all producers exercise caution by having their livestock tested for TB by an accredited veterinarian. This will help ensure the disease has not spread to their herd. In addition, the following measures should be taken:

Keep a "closed" herd. This means raising your own replacement stock. If this is not feasible or practical, demand that sellers provide historical health information and records about the herd of origin. It is best to buy from accredited TB-free herds.

If you cannot obtain health histories, make sure any prospective livestock are test before purchase. Isolate these animals and have them retested in 60 days by an accredited veterinarian.

Maintain fences in good repair to keep animals from commingling with other herds and animals.

Cooperate with State and Federal animal health officials who are performing trace back investigations.
