The Canadian Food Inspection Agency (CFIA) is continuing to make progress in its bovine TB investigation in response to the detection of the disease in an Alberta cow in September 2016.

The CFIA has depopulated the infected herd and the highest risk herds that co-mingled with the infected herd. Six cases of bovine TB were confirmed in the index herd. The CFIA has also identified animals that left the infected herd in the last five years (trace-out animals) so that the trace-out animals could be destroyed and their herds could be quarantined and tested. The testing for trace-out animals is largely complete with no additional cases to date.

The on-farm testing of trace-in herds (approximately 15,000 animals) is complete. Premises will continue to be released from quarantine as laboratory and post-mortem examination results are received.
