Single Presumptive Case of ISA at Marystown Facility

Re: Grieg Seafood Newfoundland Press Release

Project Status Update:
Marystown, Canada

Grieg Seafood Newfoundland (GSN) is providing mandatory notice that one (1) Atlantic salmon parr in one of our 2020/2021 trial groups of fish has provided a suspect detection for Infectious Salmon Anemia (ISA) during routine health inspections at our Marystown facility. The impacted tank contains 118,000 individuals.

More analysis is needed to determine whether the fish is infected or not. The detection has not been confirmed by regulatory agencies.

Further testing is ongoing in cooperation with veterinarians from the province, with independent analysis to be provided from accredited labs. All precautionary infection control measures are implemented, in line with regulations.

The fish in question was recently vaccinated against ISA. Current stock are not showing any symptoms of disease, nor has there been any instances of increased mortality.

We will release more information in the coming weeks.
