There have been no new confirmed cases of bovine tuberculosis reported. To date there has been six confirmed cases, including the cow that had the disease when it was slaughtered in the United States.
All six cases are from one herd over the span of 18 different locations.
Other than the handful of positive cases, no samples tested showed lesions consistent with TB. While this is encouraging news, it does not confirm that the animal does not have TB. Whether or not the animal in question has TB can only be confirmed with a positive or negative culture test.
About 50 premises are still quarantined, which affects around 26,000 animals.
During investigation, the Canadian Food Inspection Agency traces the movement of animals that enter or leave an infected herd. The CFIA also traces activity to try and identify where and when the disease introduced into the herd. This can lead to more farms being quarantined, but does not mean the disease is necessarily spreading. This is regular procedure and can take up to several months to complete.
For those who have been quarantined, the CFIA Cleaning and Disinfection Unit will conduct assessments, develop decontamination plans and issue owners of the premises an Order to Clean and Disinfect.
