Canada has closed it’s bovine tuberculosis investigation as officials say no further cases found have been found since discovered nearly two years ago.
The Canadian Food Inspection Agency Monday reported receiving the last of the lab culture test results on about 30,000 animals tested during its probe. The investigation started in 2016 after finding six cases of bovine tuberculosis in cattle, which was first discovered in a U.S. slaughterhouse. The agency expects to publish a summary report online in June.
The AgCanada Network reports that animals across 79 “trace-out” herds and 71 “trace-in” herds were tested. From those, about 11,500 cattle were ordered destroyed, but no further cases were discovered. No source of infection has been identified for the six TB-positive cattle found in the investigation. Cattle producers have received about $39 million in compensation for the destroyed animals.
The successful investigation allows Canada to keep its bovine tuberculosis-free status regarding global trade.
