Norway Reports Two Outbreaks of Infectious Salmon Anaemia Virus

Norway, the world’s biggest producer of Atlantic salmon, reported two separate outbreaks of infectious salmon anaemia, a contagious viral illness that has wiped out fish farms from the Arctic to Chile.

An outbreak in the Helgeland district in Nordland county that started on May 28 killed about 3,000 salmon from a farm with 385,000 fish, the first occurrence of the disease in the area, the Norwegian Food Safety Authority reported in a notification to the World Organisation for Animal Health today.

In Troms, to the north of Nordland, the virus killed 50,000 salmon out of a population of 1.22 million susceptible fish, and 138,500 salmon were destroyed, the food-safety authority reported in a separate notice.
