Brazil reports atypical case of mad cow disease: ministry

SAO PAULO (Reuters) - The Brazilian government reported on Friday a case of atypical mad cow disease in an animal in Mato Grosso state, according to a statement from the country?s Agriculture Ministry.

The ministry said the case of mad cow disease, or bovine spongiform encephalopathy (BSE), was detected in a 17-year-old cow. It said it collected the necessary material for tests and incinerated all other parts of the cow.

?No part of the animal entered the food chain, there are no risks for the population,? the statement said.

The case was considered ?atypical? as the animal contracted the BSE protein spontaneously, rather than through the feed supply. Classical cases of mad cow are caused when cattle are fed brain or spinal tissue of other ruminants, which is now forbidden in nearly all beef producing countries including Brazil...

[TD]As part of the Brazilian surveillance system for Bovine Spongiform Encephalopathy (BSE), a 17-year-old beef cow that was found fallen during an ante-mortem inspection at slaughter was confirmed as a case of 'atypical BSE', classified as H-type. After screening tests performed by the National Laboratory of Pernambuco LFDA/PE indicated the presence of prion antigens, the samples were sent to CFIA's OIE BSE reference laboratory in Lethbridge, Alberta, and the confirmation diagnostic test was concluded on 31 May 2019. This is the third case of 'atypical BSE' identified in more than 20 years of surveillance in Brasil. The last case has been detected in 2014. Specified Risk Material was duly removed and incinerated at the slaughterhouse. Meat and other products from this animal did not enter the food chain and pose no risk for human and ruminants populations. According to the OIE Terrestrial Code, for the purposes of official BSE risk status recognition, 'atypical BSE' is a condition believed to occur spontaneously in all cattle populations at a very low rate. Therefore, this event does not have any influence on official BSE risk status recognition of Brasil. This investigation was concluded.[/TD]
