Bovine Tuberculosis Found in South Dakota Cattle Herd

By Krystal Miga

The state veterinarian says bovine tuberculosis, or TB, has been confirmed in a cow herd in Kingsbury County.

Dr. Beth Thompson said the infected herd was identified through traceback efforts on a Hamlin County feedlot steer.

Meat inspectors initially discovered the infected steer during routine inspections at a Wisconsin packing plant in late October.

Thompson said they’re working closely with the herd owner, USDA and state Animal Industry Board to trace other infected animals and protect the health of the state’s cattle industry.

Officials said Bovine TB is not currently a threat to food safety in the U.S, due to milk pasteurization and comprehensive meat inspection programs.
