Enzootic bovine leukosis (EBL) in cattle

Norway is regarded as free from enzootic bovine leukosis.

The aim of the surveillance and control programme for enzootic bovine leukosis (EBL) is to document freedom from the infection in Norway according to Council Directive 64/432/EEC and to contribute to the maintenance of this favourable situation.


All milk and blood samples tested in 2022 were negative for antibodies against bovine leukemia virus (BLV).
