Canada confirmed its first case of mad cow disease since 2011 on Friday but said the discovery, which helped drive cattle prices higher, should not hit a beef export sector worth C$2 billion ($1.6 billion) a year.
The Canadian Food Inspection Agency (CFIA) said no part of the animal, a beef cow from Alberta, had reached the human food or animal feed systems.
Mad cow is formally known as bovine spongiform encephalopathy (BSE), a progressive, fatal neurological disease.
“The CFIA is seeking to confirm the age of the animal, its history and how it became infected. The investigation will focus in on the feed supplied to this animal during the first year of its life,” the agency said.
