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.


In late September, the United States Department of Agriculture (USDA) notified the Canadian Food Inspection Agency (CFIA) that a case of bovine TB had been detected in a cow from Alberta when it was slaughtered in the United States. The CFIA initiated an investigation into the case and is working with provincial agriculture and health authorities.

Quarantines could be found in other areas of these respective provinces as the investigation continues.

The priority area for the CFIA investigation is domestic livestock. The Agency is working with the Government of Alberta 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.

If you have been contacted by the CFIA:

The CFIA has prepared information for producers who are contacted in the course of a disease investigation.

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.

For information on how compensation is determined and how the process works visit:

Financial assistance

Financial assistance for other costs not covered by the compensation administered by the CFIA, such as those related to feed, business interruptions, etc., may be possible under Agriculture and Agri-Food Canada (AAFC) programs.
