Two cows from a Saskatchewan ranch have tested positive for bovine tuberculosis, according to the Canadian Food Inspection Agency.
In February, the U.S. Department of Agriculture notified CFIA of a positive test for bovine TB in a tissue sample from a cow exported to an American feedlot from Saskatchewan in September 2022.
The herd of origin was tested in May, reactor animals slaughtered and two cases of bovine TB confirmed June 19.
