Brucella abortus in cattle was not detected in 2012.

The aim of the programme is to document freedom from Brucella abortus in cattle according to demands in Directive 64/432/EEC with amendments, and to contribute to the maintenance of the present favourable situation.

Eradication of bovine brucellosis in Norway was achieved in 1950. 

Since 1994, the EFTA Surveillance Authority (ESA) has recognised Norway as a state officially free from brucellosis as described in ESA Decision 66/94/COL, later replaced by ESA Decision 227/96/COL.

A surveillance and control programme for Brucella abortus was launched in 2000. All samples were negative in 2000, 2001, 2003 and 2004. In 2002 however, two bulk milk samples were antibody positive. Further investigation did not confirm these positive results and it was concluded that the positive serological results most likely were false positive reactions. 

Since 2005 the programme has consisted of passive clinical surveillance. 

The Norwegian Food Safety Authority is responsible for carrying out the programme. The Norwegian Veterinary Institute is in charge of planning the programme, performing the analyses and reporting the results. The samples are collected by inspectors of the Norwegian Food Safety Authority.
