Brucellosis and Bovine Tuberculosis: Importation of Cattle and Bison

We are amending the regulations governing the importation of cattle and bison with respect to bovine tuberculosis and brucellosis to establish a system to classify foreign regions as a particular status level for bovine tuberculosis and a particular status level for brucellosis. We are also establishing provisions for modifying the bovine tuberculosis or brucellosis classification of a foreign region. Finally, we are establishing conditions for the importation of cattle and bison from regions with the various classifications. The changes will make the requirements clearer and assure that they more effectively mitigate the risk of introduction of these diseases into the United States.
