The Montana Department of Livestock is monitoring the bovine tuberculosis investigation in Canada, the state agency announced.
In late September, the Canadian Food Inspection Agency initiated an epidemiological investigation after bovine TB was detected in a Canadian cow at a United States slaughter facility. As of Dec. 2, there are six confirmed cases of bovine TB in Canada, including the index animal detected at slaughter in the US. Of the roughly 40 premises currently under quarantine, most are located in Southeast Alberta with about five premises in Saskatchewan.
Cattle entering the U.S. from Canada must be tested for TB prior to import.
“Despite what feels like close proximity of this incident, Montana cattle producers remain safe,” said Montana State Veterinarian, Marty Zaluski. “Canada’s vigorous response, combined with our requirement that Canadian cattle be TB tested before entering Montana, keeps the risk low for ranchers in the state.”
Zaluski said the state is not planning to place additional requirements on Canadian cattle coming to Montana at this time.
“I am closely monitoring CFIA’s efforts and am ready to act aggressively if needed,” said Zaluski.
Historically, DOL has recognized the efforts of other state and provincial animal health officials to effectively deal with disease events, and expects the same in return, the state agency said.
CFIA policy requires that all positive animals and any animals exposed to positive animals be humanely destroyed. All exposed animals will be tested first and those that test negative will be eligible to enter the food supply.
At this time, approximately 10,000 cattle are to be destroyed, the DOL said. The strain of TB identified in the index case closely resembles a strain associated with cattle in Central Mexico, suggesting that wildlife are an unlikely source.
