The virus had been detected by Real Time PCR screening. The mortality at the site is low and there are no clinical signs of outbreak.

According to the OIE, from an epidemiological point of view, the Norwegian Food Safety Authority considers the ISA outbreak at 11238 Langøyhovden to be a reoccurrence since ISA was present at another location in the same area one year ago.

The neighbour farm with the previous ISA case, 11248 Bonhammaren, is located 10 kilometers away from Langøyhovden. The two sea sites are operated by different companies. The virus relating to the recent ISA outbreak will be further characterised in relation with the epidemiologic studies.

The Langøyfjord site contains approximately 660000 fish of an average live weight of 2.6 kg. Out of these 173 000 fish (average weight 2 kg) will be culled. The culling of 173 000 fish at the Langøyhovden site is expected to have only limited financial impact.

The control of the fish at the site will continue harvesting will be done in agreement with the Food Authority.
