Bovine tuberculosis in Saskatchewan

On February 23, 2023, the United States Department of Agriculture (USDA) notified the Canadian Food Inspection Agency (CFIA) that tissues collected at slaughter from a heifer originating from Canada had a positive polymerase chain reaction (PCR) test for bovine tuberculosis. The animal was exported from Saskatchewan in September 2022 and was in a US feedlot until its slaughter.

The CFIA is continuing to work closely with the producers, industry associations, and provincial and federal agricultural and health authorities throughout the investigation.
