During routine fish health tests on 14 May, Mainstream Canada''s Dixon Bay farm tested positive for the IHN (Infectious Haematopoietic Necrosis) virus.

"This is the first diagnosis of IHN among farmed Atlantic salmon in BC since 2003. Although IHN kills up to 100% of exposed Atlantic salmon, wild salmon in marine waters are very resistant to IHNV infection," said Gary Marty, fish pathologist for the BC Animal Health Centre.
