The number of cases of bovine tuberculosis has climbed to six, while a quarantine has expanded to 36 farms in Alberta and Saskatchewan, the Canadian Food Inspection Agency (CFIA) said Friday. The disease first surfaced in a single cow flagged by the United States Food Inspection Agency (USDA) in late September. On Friday, the CFIA reported five additional cases from the same herd. The agency also announced that a quarantine has been expanded to 34 farms in southern Alberta and two in southwest Saskatchewan. The situation has caught ranchers off guard, considering there has not been a case of bovine TB in Canada since 2011.
