§ Mr. Malcolm BruceTo ask the Secretary of State for Scotland if he will make a statement on the incidence of infectious haematopoietic necrosis within the salmon fish farming industry.
§ Mr. Lang[holding answer 11 May 1990]:Infectious haematopoietic necrosis (IHN) has never been identified in the United Kingdom in either our farmed or wild salmonid fish stocks, despite extensive testing over many years. Moreover, IHN is a notifiable disease in the United Kingdom and its presence or any suspected outbreak would have to be reported to the appropriate fisheries department.
