A routine check by salmon farming giant Leroy Seafood at its Skorpo Vest site in Bjornefjorden has detected the presence of infectious salmon anemia (ISA).

The company is not waiting to verify samples and has now started harvesting the fish, which are market size, Leroy Public Affairs Manager Krister Hoaas told IntraFish.

The site is located in an ISA monitoring zone and is the fifth case in the same control area, according to Norwegian Food Safety Authority Regional Director Ole Fjetland.

If suspicions are confirmed upon verification of samples, the Norwegian Food Safety Authority will make changes to the existing control area, with local adaptations to the topography and flow conditions within a 10-20 kilometer radius of the site, which is in a very production-heavy region.
