Bovine TB probe wraps with no exact point of entry found

'More stringent' tests now being run on U.S. rodeo cattle imports

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,

On-farm tests wrap up in bovine TB probe

CFIA investigation turns up just four positive B.C. cattle

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

Few herds remain in B.C. bovine TB probe

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

TB-resistant cattle are a reality

A new technique has produced live animals with 
increased resistance to this dangerous disease

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.
