Cefas Fish Health Inspectorate Investigate VHS - UK - Viral haemorrhagic septicaemia (VHS) was diagnosed in rainbow trout at a fish farm in North Yorkshire on 26 May 2006. This is the first record of a VHS outbreak in mainland GB.

Status Report

Statutory controls were promptly placed on the affected farm and in order to prevent the further spread of disease the fish stocks were humanely destroyed under the supervision of the Centre for Environment, Fisheries and Aquaculture Science (Cefas). The farm has now been drained of water and is preparing for disinfection.

To facilitate the containment of the disease and to establish the extent of the infection statutory controls were placed on all fish farms in the Ouse catchment.

The Cefas Fish Health Inspectorate have now inspected all fish farms holding susceptible species in the Ouse catchment. There was no evidence of clinical disease in any of the farms, and samples are now being tested for the presence of the virus.

In addition the Environment Agency suspended all fish introduction and movement consent applications in the catchment whilst investigations into the extent of the disease outbreak are conducted. Testing of the wild fish population adjacent to the infected farm is underway. Preliminary results have revealed no evidence of disease in the wild fish. Investigations are also taking place into the potential source of the infection.
