  • Unknown or inconclusive
Epidemiological comments As part of the German targeted bovine spongiform encephalopathy (BSE) surveillance system, a case of BSE classified as atypical (L-type) was identified in a cow at slaughter. An epidemiological investigation of the event was conducted. The summary of the event is as follows: • The cow was slaughtered at the age of ten years and five months without clinical signs of disease. • Results from immunoblot tests at the National Reference Laboratory (Friedrich-Loeffler Institute) confirmed the animal positive for atypical BSE of the L-type, a very rare form of the disease not generally associated with an animal consuming infected feed. • The animal’s carcass was destroyed. The identified animal did not enter food supply channels, and so at no time did it present any risk to human health. • The epidemiological investigation identified seven offspring cattle, five of which were already slaughtered and two of which were still on the farm of origin and have been killed and destroyed. The tracing of the bovines born on the farm from one year before until one year after the birth of the identified cow revealed 5 bovines which have subsequently been killed and destroyed. The OIE does not recognize an atypical form of BSE as a distinct entity for the purpose of its international standards; therefore, it is not mentioned in the OIE Terrestrial Animal Health Code, which does not distinguish between different forms of BSE.
