Some countries do not require goats and breeding swine to be tested for tuberculosis and brucellosis prior to export. However, APHIS’ current regulations require that such testing be conducted. The proposed amendments would relieve this unnecessary burden on producers by exempting goats and breeding swine from tuberculosis and brucellosis testing prior to export when testing is not required by the receiving country.
