This investigation involves a significant number of premises and requires the tracing of the movement of animals in recent years, plus testing. It is therefore not expected to be completed for several months.
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 next phase of the bovine TB investigation will involve trace-in herds.
The priority area for the CFIA investigation is domestic livestock. The Agency is working with the provincial governments to ensure that any risks associated with TB in wildlife are included in the investigation.
Genetic analysis showed that the bovine TB organism from the infected cows is not the same as any strains detected in Canadian domestic animals or wildlife or humans to date. All six currently confirmed positive cows have the same strain of TB. This strain of TB identified in these confirmed positive cows is closely related to a strain first found in cattle in Central Mexico in 1997.
Information for Producers
Movement of cattle and other animals
Only premises that have been placed under quarantine by the CFIA are prevented from moving animals without permission. Producers in the general investigation area that have not been contacted by the CFIA are allowed to move animals (including sending cattle to auction markets and feed lots) but must comply with livestock identification requirements.
Quarantine and testing
Premises that are under quarantine must not move any animals without permission from the CFIA.
As the disease investigation proceeds, additional premises may need to be quarantined while cattle are tested for bovine TB.

Additional information and guidance from CFIA staff will be provided to individual producers if their animals are required to be quarantined. While testing is completed as quickly as possible, quarantines remain in effect until all susceptible animals have tested negative for the disease.
If an animal under quarantine tests positive for bovine TB, the CFIA will follow established procedures for destruction and compensation.
Under the Health of Animals Act, the CFIA may compensate producers for:
- animals ordered destroyed;
- other things ordered destroyed, such as contaminated feed or animal products; and
- the disposal costs of animals ordered destroyed.
