NORWAY - An outbreak of Infectious salmon Anaemia (ISA) has been confirmed on a Marine Harvest farm in Lille svr (10990), Dnna, Nordland.

Of the 170,000 salmon susceptible, 1000 cases were reported.

The Norwegian Food Safety Authority believes that this ISA outbreak at Dønna is a first occurrence at this site. ISA was present at another location 15 km away in July 2013.

The Norwegian Veterinary Institute uses genotyping to determine whether ISA outbreaks are an occurrence or a reoccurrence. The epidemiological survey relating to this ISA outbreak shows no genotypic association to the previous ISA outbreak at the other mentioned location. Therefore this event is reported as a first occurrence.

The ISA cases seem to be two separate outbreaks without any epidemiological correlation, although both of them belong to the same administrative region, Nordland.

The virus relating to the outbreak will be further characterized associated with the epidemiological studies.
