Effective Aug. 22, tuberculosis (TB) and brucellosis testing requirements for feeder cattle going to Canada have been eliminated, USDA's Animal and Plant Health Inspection Service says. The agency says Canadian animal health authorities have recognized the U.S. success in eradicating TB, brucellosis and other diseases by establishing the Restricted Feeder Cattle Program, which allows certain untested feeder cattle to enter Canada. To participate, feeder cattle must originate from a state designated as brucellosis- and TB-free.
