Tuberculosis in Cattle, Bison, and Captive Cervids; State and Zone Designations

We are amending the bovine tuberculosis regulations to establish several new levels of tuberculosis risk classifications to be applied to States and zones within States. Additionally, we are providing for the classification of States and zones according to their tuberculosis risk with regard to captive cervids. We are also amending the regulations to increase the amount of testing that must be done before certain cattle and bison may be moved interstate. These changes are necessary to help prevent the spread of tuberculosis and to further the progress of the domestic tuberculosis eradication program.
