All 18,343 samples, originating from 8,466 herds, were tested negative for BSE in 2012.

The aim of the surveillance programme is to document that the Norwegian cattle population is free from BSE.

The BSE surveillance programme was initially based on passive surveillance (1998-2000), with active surveillance introduced in May 2000. Inthe period 1998-2000 the samples were investigated by histopathological examination. From 2001 onwards the samples were examined by an Enzyme-Linked ImmunoSorbent Assay (ELISA) method for detection of resistant prion protein (PrPSc). In addition, clinically suspected animals were also investigated by Western blot investigation for the detection of PrSc and/or histopathological examination according to the protocol of the Office International des Epizooties (OIE). BSE has never been detected in any of the examined animals.
