ISAV virus not found in Washington salmon

May 31, 2013

Tribal and federal resource managers announced that tests on salmon from Washington waters show no signs of a fish virus called Infectious Salmon Anemia Virus.

ISAV was not detected in tissue samples taken from more than 900 wild and hatchery-produced salmon.

ISAV is not harmful to people, but specific strains have caused a deadly disease in farm-raised Atlantic salmon. Outbreaks with significant losses have occurred Maine, Canada, Chile and several European countries.

ISAV has not been documented in farmed, wild or hatchery salmon in Washington.
John Kerwin, Fish Health Program manager for the Washington Department of Fish and Wildlife, said concerns about the possibility of the virus occurring in Washington’s salmon prompted the tests, part of a two-year monitoring program specifically designed to detect ISAV.

Elsewhere on the west coast, there have been no confirmed reports of ISAV in wild, hatchery or farmed salmon. In 2011, a Canadian researcher reported detecting the virus in some British Columbia salmon. However, the Canadian Food Inspection Agency, the federal agency with authority for fish health in Canada, tested fish tissue samples and found no ISAV present.

Additional monitoring programs are under way in Alaska and Canada.
