The CFIA’s investigation into a case of Bovine Tuberculosis in Alberta has now spread to 33 farms in Southeast Alberta and 2 farms in Southwest Saskatchewan.

The two Saskatchewan farms are under quarantine and movement controls are in place.

CFIA inspectors and veterinarians have apparently expanded their scope to include farms in Rural Municipalities south of the South Saskatchewan River and west of Highway 4.

CFIA inspectors are conducting on-farm testing and tracing of potentially exposed animals.

Additional staff has been brought in to help with the investigation which began from a confirmed case of TB on a farm near Jenner.

The CFIA says the investigation is not expected to be complete for several months.

The investigation involves a significant number of herds and requires the tracing of the movement of animals for the past five years plus testing.
