Cattle From Mexico

We are amending the animal importation regulations to prohibit the importation of Holstein cross steers and Holstein cross spayed heifers from Mexico. The regulations have prohibited the importation of Holstein steers and Holstein spayed heifers from Mexico due to the high incidence of bovine tuberculosis in that breed, but have not placed any special restrictions on the importation of Holstein cross steers and Holstein cross spayed heifers from Mexico. Given that the incidence of bovine tuberculosis in Holstein cross steers and Holstein cross spayed heifers from Mexico is comparable to the incidence of tuberculosis in Holstein steers and Holstein spayed heifers, this action is necessary to protect the health of domestic livestock in the United States.
