On March 3rd, 2023, the National Centre for Animal Diseases/Canadian Food Inspection Agency (NCAD/CFIA), Lethbridge Laboratory, WOAH reference laboratory, issued a conclusive result of the Western Blotting test with atypical H-type BSE detected. This is the sixth case of atypical H-type BSE registered in Brazil in more than 25 years of surveillance for the disease. Brazil has never diagnosed a classical BSE case, maintaining, since 2012, official recognition by the WOAH as a country of negligible risk for the disease. The investigation has been completed.

Brazil MAPA OMSA Confirms BSE TSE Prion atypical H-type
OFFICIAL NOTE - Map confirms that case of Bovine Spongiform Encephalopathy is atypical type H
Ministry is immediately adopting measures so that exports of Brazilian beef are reestablished as soon as possible
Published on 03/02/2023 22:18 Updated on 03/03/2023 00:08
According to the indications of the technical staff of the Ministry of Agriculture and Livestock (MAPA), the analysis of the reference laboratory of the World Organization for Animal Health (OMSA) confirmed, on Thursday night (02), that the isolated case of Spongiform Encephalopathy Bovine (BEE) detected in the municipality of Marabá (PA) is atypical type H.
The Minister of Agriculture and Livestock, Carlos Fávaro, immediately communicated the result of the sample to President Luiz Inácio Lula da Silva and immediately began inserting said information into the system for official communication to the WHOA and the Chinese authorities.
Once the process is completed, a virtual meeting will be scheduled with the Chinese government to deal with the release of beef exports to the country.
"I emphasize that speed, efficiency and the transparency requested by President Lula was fundamental. I thank our team and that of the governor of Pará, Helder Barbalho, who allowed us to act quickly from the identification of the case", commented Fávaro.
As this is an atypical case, that is, it occurred due to natural causes in a single 9-year-old animal and with all health measures promptly adopted, the Ministry of Agriculture and Livestock is immediately adopting measures, in accordance with health protocols , so that Brazilian beef exports are reestablished as soon as possible.

OFFICIAL NOTE
Mapa adopts measures on BSE case in Brazil
Meat for market consumption is not affected by confirmation
Published on 02/22/2023 8:15 pm Updated on 02/22/2023 9:51 pm
Faced with the confirmation of a case of Bovine Spongiform Encephalopathy ('mad cow disease') in a 9-year-old male animal on a small property in the municipality of Marabá (PA), the Ministry of Agriculture and Livestock (Mapa) has been adopting all the necessary government measures for the Brazilian meat market.
The World Organization for Animal Health (WHOA) was notified and the samples were sent to the institution's reference laboratory in Alberta, Canada, which will be able to confirm whether the case is atypical.
The animal, raised on pasture, without feed, was slaughtered and its carcass incinerated on site. The official Brazilian veterinary service is carrying out the epidemiological investigation which may be continued or terminated depending on the result.
“All measures are being adopted immediately at each stage of the investigation and the matter is being treated with total transparency to guarantee Brazilian and global consumers the recognized quality of our meat”, highlighted Minister Carlos Fávaro.
Following the official health protocol, exports to China will be temporarily suspended from this Thursday (23). However, the dialogue with the authorities is being intensified to demonstrate all the information and the prompt reestablishment of the Brazilian beef trade.

''H-TYPE BSE AGENT IS TRANSMISSIBLE BY THE ORONASAL ROUTE''
This study demonstrates that the H-type BSE agent is transmissible by the oronasal route. These results reinforce the need for ongoing surveillance for classical and atypical BSE to minimize the risk of potentially infectious tissues entering the animal or human food chains.
www.ars.usda.gov/research/publications/publication/?seqNo115=353094
OIE Conclusions on transmissibility of atypical BSE among cattle
Given that cattle have been successfully infected by the oral route, at least for L-BSE, it is reasonable to conclude that atypical BSE is potentially capable of being recycled in a cattle population if cattle are exposed to contaminated feed. In addition, based on reports of atypical BSE from several countries that have not had C-BSE, it appears likely that atypical BSE would arise as a spontaneous disease in any country, albeit at a very low incidence in old cattle. In the presence of livestock industry practices that would allow it to be recycled in the cattle feed chain, it is likely that some level of exposure and transmission may occur. As a result, since atypical BSE can be reasonably considered to pose a potential background level of risk for any country with cattle, the recycling of both classical and atypical strains in the cattle and broader ruminant populations should be avoided.

3. Atypical BSE
The Group discussed and endorsed with minor revisions an overview of relevant literature on the risk of atypical BSE being recycled in a cattle population and its zoonotic potential that had been prepared ahead of the meeting by one expert from the Group. This overview is provided as Appendix IV and its main conclusions are outlined below. With regard to the risk of recycling of atypical BSE, recently published research confirmed that the L-type BSE prion (a type of atypical BSE prion) may be orally transmitted to calves1 . In light of this evidence, and the likelihood that atypical BSE could arise as a spontaneous disease in any country, albeit at a very low incidence, the Group was of the opinion that it would be reasonable to conclude that atypical BSE is potentially capable of being recycled in a cattle population if cattle were to be exposed to contaminated feed. Therefore, the recycling of atypical strains in cattle and broader ruminant populations should be avoided.
The Group acknowledged the challenges in demonstrating the zoonotic transmission of atypical strains of BSE in natural exposure scenarios. Overall, the Group was of the opinion that, at this stage, it would be premature to reach a conclusion other than that atypical BSE poses a potential zoonotic risk that may be different between atypical strains.
