Tuberculosis Testing for Imported Cattle

We are amending the animal import regulations to require that an import permit be obtained for the importation of cattle from Mexico; to require certification regarding the tuberculosis history of the herds from which a group of cattle is assembled for export to the United States; to require information regarding each premises where cattle intended for export to the United States have resided; and to add a definition for herd of origin and revise the definitions of herd, official tuberculin test, and whole herd test. This action is necessary to help us better ensure that imported cattle are free of tuberculosis, thereby protecting against the spread of tuberculosis within the United States.
