The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) confirmed in October 30 press release that a Wisconsin dairy herd in Dane County (the county the city of Madison is located in) has tested positive for bovine tuberculosis (TB).

Meat inspectors identified a carcass during a routine slaughter inspection and sent a sample to the National Veterinary Services Laboratory for testing. Through animal identification records, the carcass was traced back to a herd in Dane County that DATCP immediately quarantined. A quarantine prevents any animals from moving on or off of the farm.

“We are working closely with the herd owner, U.S. Department of Agriculture, Department of Health Services, area veterinarians, industry partners, and other herd owners. We are taking aggressive measures to control and prevent the spread of this disease,” said Dr. Darlene Konkle, DATCP’s acting State Veterinarian. “Our staff and partners train for these types of responses and are taking the necessary steps to protect animal and human health.”

Federal food safety laws prevent meat from infected animals from entering the food chain. State and federal inspectors at slaughter plants evaluate live animals and animal products for signs or symptoms of disease and remove any from entering food production.

Bovine TB is a respiratory disease of cattle is a chronic, slowly progressing progressive disease meaning it can take months to years to worsen. Infected animals may pass the infection to other animals even if they appear healthy. Animals often do not show signs until the infection has reached an advanced stage.

Wisconsin has been certified as TB-free since 1980. With a thorough investigation and containment of an outbreak Wisconsin will maintain its TB-free status with USDA, according to DATCP.
