The CBC News reports:
Thirty ranches in southeast Alberta are under quarantine after a case of bovine tuberculosis was detected in late September in a cow headed to slaughter in the United States, according to the Canadian Food Inspection Agency.
The cow was from a ranch near Jenner, Alta., north of Medicine Hat.
A CFIA investigation with veterinarians and investigators is underway, and the quarantined ranches are all located in the Buffalo Atlee and Suffield Block community pastures. According to the CFIA website, more ranches may become part of the investigation.
Ranchers have feared in the past that the disease may have been caused by the ever-growing elk population in the area, but a CFIA official would not confirm if that is the case.
