Mowi's Northern Harvest Sea Farms suspects the presence of the Infectious Salmon Anaemia (ISA) virus at its McGrath Cove North and Ironskull Point marine sites off the south coast of Newfoundland, Canada.

In each case, the suspect detections occurred in one Atlantic salmon from one cage at each site that was sampled through the provincial government's Department of Fisheries, Forestry, and Agriculture’s s aquatic animal health surveillance program.
