Canada’s top ag minister toured a ranch near Jenner on the weekend. It was the epicentre of the bovine TB outbreak that began in September of 2016. During the investigation, the CFIA quarantined dozens of ranches in southern Alberta, Saskatchewan and Manitoba. More than 30 thousand cattle were tested, but only 6 cattle from the initial farm tested positive for the disease. All quarantines were lifted in February. The federal minister called it a positive step forward for the industry. The strain that was found in the cow from Jenner, had also shown up in cattle in Mexico, more than 2 decades earlier. It’s unlikely the source of the infection will ever be found.
