The Brazilian Bovine Spongiform Encephalopathy (BSE) Surveillance System detected two cases of atypical BSE, type H in two beef cows in meat plants in two different states–Minas Gerais and Mato Grosso.
The case in Minas Gerais was a 11-year-old beef cow destined for emergency slaughter in a slaughterhouse, while Mato Grosso case was a 10-year-old beef cow destined for emergency slaughter in a slaughterhouse.
The samples were sent to the OIE Reference Laboratory for BSE at the Canadian Food Inspection Agency in Lethbridge, Alberta. The results of the confirmatory test were obtained on September 3, 2021.
These are the fourth and fifth cases of atypical BSE identified during 23 years of surveillance in Brazil. The last case was detected in 2019.
The meat and other products of these animals will not enter the food chain and do not represent a risk to ruminant populations.
BSE (bovine spongiform encephalopathy) is a progressive neurological disorder of cattle. BSE has been called “mad cow disease.”
