Federal inspectors have formally closed the book on a 2018 outbreak of bovine tuberculosis (TB) in a British Columbia cattle herd, but with “no definitive source of infection” found. The probe dates back to October that year, when a beef cow of an unknown age, from a cow-calf operation in B.C.’s southern Interior, was culled,
The “trace-in” phase of Canada’s latest bovine tuberculosis (TB) investigation has ended with just four cattle from one British Columbia herd testing positive for the disease. The Canadian Food Inspection Agency last week announced all on-farm testing has been completed in its probe, which dates back to November 2018 when lab tests confirmed TB in
All cattle that moved away from a British Columbia farm where four animals were found to be infected with bovine tuberculosis (TB) have been tracked down and tested. The Canadian Food Inspection Agency said Tuesday it has completed its “trace-out” investigation stemming from last fall’s discovery of a TB-positive beef cow from a farm in
The federal investigation into an outbreak of bovine tuberculosis affecting four animals in a domestic British Columbia cattle herd has pulled back to include just seven properties. As of Monday, the Canadian Food Inspection Agency’s probe included one herd each in B.C. and Saskatchewan and four herds in Alberta under movement controls, along with the
Canada’s latest outbreak of bovine tuberculosis in domestic cattle involves a strain of TB bacteria not related to any previously seen in Canadian livestock or wildlife. Culture testing of bacteria taken from a cow confirmed as TB-positive in November shows it’s “not related to past cases of bovine TB in Alberta or British Columbia or
Updated, Dec. 20 — Cattle from four more herds in British Columbia and two in Alberta are now being tested for bovine tuberculosis as officials probe the country’s latest domestic case of the disease. The Canadian Food Inspection Agency on Monday reported the six herds are now under “movement controls” while TB testing is underway.
As trade tensions rise between the U.S. and Canada, Manitoba’s beef industry is celebrating the removal of a long-standing irritant. The U.S. Department of Agriculture has rolled back testing requirements on bovine tuberculosis for breeding stock, an issue that producers say has hovered over their industry since 1997, when the CFIA downgraded Manitoba’s TB status.
An investigation across three provinces following the appearance of bovine tuberculosis (TB) in six Prairie cattle in 2016 has officially closed with no further cases found. The Canadian Food Inspection Agency on Monday reported receiving the last of the lab culture test results on about 30,000 animals tested during its probe. “All of the results
Researchers say they’ve found a high-tech way to produce cattle with genetic resistance to bovine tuberculosis. Writing in the open-access journal Genome Biology, Chinese researchers from the Northwest A&F University in Shaanxi, China say CRISPR gene-editing technology allowed the breakthrough.

With no new cases of bovine tuberculosis discovered on the Prairies since mid-November, federal officials are now turning their focus to how the disease got into half a dozen cattle in the region last fall. The Canadian Food Inspection Agency said Friday it has finished TB-screening and depopulating all mature cattle from 18 properties that
