The Canadian Food Inspection Agency (CFIA) investigation and testing following a November 29, 2024, case of bovine tuberculosis (bovine TB) has detected the disease in the herd where the infected animal spent most of its life before slaughter. The CFIA disease investigation is ongoing.
Investigation status as of 2025-06-05

- 7 lifeline herds (herds traced from an infected animal in the infected herd), with 3 herds released from quarantine
- 32 trace-out herds (herds that received animals from the infected herd), with 8 herds released from quarantine
- The CFIA continues to identify and prepare for testing on:
- trace-in herds (herds that provided animals to the infected herd)
