Canada has reported an outbreak of atypical bovine spongiform encephalopathy (BSE), also known as 'mad cow disease', at a farm in Alberta to the World Organization for Animal Health (OIE). In response, South Korea's Ministry of Agriculture, Food and Rural Affairs has halted the import quarantine for Canadian beef. The Canadian Food Inspection Agency confirmed the infection in an 8.5-year-old cow, marking the first case in Canada since 2015. The decision to restart the quarantine will depend on the epidemiological information and quarantine measures provided by Canada.
