    • Epidemiological comments
      • As part of the German targeted bovine spongiform encephalopathy (BSE) surveillance system, a BSE-case classified as atypical (H-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 on 30.01.2014 at the age of eleven years and four months without clinical signs.
        • Results from the immuno blot tests at the NRL (Friedrich Loeffler-Institute) confirmed the animal positive for atypical BSE of the H-type, a very rare form of the disease not associated with feeding.
        • The animal?s carcass has been destroyed. The identified animal did not enter the food channels; at no time it presented any risk to human health.
        • The epidemiological investigation identified eight offspring cattle, three of which were already slaughtered, one of which has been fallen and four of which have been traded to another Member State. The tracing of the bovines born on the farm from one year before until one year after the birth of the identified cow revealed 371 bovines (177 have been already slaughtered, 63 were fallen stock, 3 have been traded within the territory of Germany, 127 have been traded to other States, one has been culled and destroyed).

      • The OIE does not recognize an atypical form of BSE as a distinct entity for the purpose of its international standards; it is not mentioned in the OIE Terrestrial Animal Health Code, which does not distinguish between different forms of BSE.
