EPIDEMIOLOGICAL COMMENTS
Isolated, single case of atypical H-type bovine spongiform encephalopathy (BSE) has been confirmed in a 17 year-old indigenous cow on a beef suckler farm. The cow was in calf and was found recumbent with no prior history of clinical signs or problems. The animal was humanely euthanized on 27/2/23, and the case was disclosed during routine national TSE statutory surveillance and testing of fallen stock cattle aged over 48 months. The animal was not presented for slaughter and did not enter the food chain. The entire carcass was disposed of as category 1 material. There is no threat to food safety or human health. Epidemiological investigations are underway. The cohort and offspring of this single atypical BSE case have been identified and placed under movement restrictions. They will be culled and the cohort screened for BSE. The detection of this single case of atypical BSE does not change the UK’s BSE disease risk status. The precise location of the farm has not been entered on the report to protect the farmer's identity and well-being
