Canada's chief veterinarian says that a reported case of bovine tuberculosis found in British Columbia is a distinct strain never before found in wildlife or domestic livestock in Canada.
During a media briefing Wednesday, Jaspinder Komal noted that three more animals from the same farm have also tested positive for bovine TB.
The first case was confirmed in early November in a mature beef cow that was slaughtered in October.
The CFIA says the affected animals never entered the food chain, adding most of the animals in the herd have been tested.
