Status of the bovine tuberculosis investigation
As the investigation proceeds, the Canadian Food Inspection Agency (CFIA) will trace the movement of animals to and from the infected herd to identify and eliminate the source and any potential spread of the disease.
Investigation status as of 2024-02-12
- 1 infected herd which has been humanely depopulated and all testing is complete
- 32 confirmed cases of bovine tuberculosis
- the bovine TB strain found in the infected herd is consistent with the strain found in the infected animal in the United States that was traced back to the Saskatchewan herd
- the strain found in the infected herd is not a close match to any strain previously reported in livestock or wildlife in North America
Life line herds (herds traced from an infected animal in the infected herd)
- the single life line herd has been released from quarantine
Contact herds (herds that shared a fence line or may have co-mingled with the infected herd)
- the single contact herd has been released from quarantine
Trace-in herds (herds that provided animals to the infected herd)
- 2 trace-in herds have been released from quarantine
- all testing of trace-in herds is complete
Trace-out herds (herds that received animals from the infected herd)
- 4 trace-out herds have been released from quarantine
- 1 confirmed trace-out herd will require live animal testing
- tracing work is continuing
If a trace-out animal is found in a terminal feedlot (animals only go to slaughter), the animal will normally be isolated from other animals and destroyed by slaughter with post-mortem inspection as soon as possible.
If a trace-out animal is found in a non-terminal feedlot where it may be in contact with breeding stock, the animal will normally be isolated from other animals and destroyed by slaughter (if it is mature enough) or will be humanely destroyed. Post-mortem inspection is completed in either case. An assessment of the disease risk status of other animals at the same premises will be completed and live animal testing will be completed as needed.
If required, tissues collected from animals at terminal and non-terminal feedlots will be sent for laboratory testing.
