Movements of Pacific oysters in Devon, UK have been restricted after a herpes virus outbreak
The oyster herpesvirus (OsHV-1 µvar) poses no threat to human life.
Following a report from a shellfish farmer of unusual deaths in farmed Pacific oyster, an inspector from the Centre for Environment, Fisheries and Aquaculture Science (Cefas) visited the affected site in the River Exe.
Samples taken were confirmed as positive for OsHV-1 µvar, and a new containment area covering the tidal waters and coastal zone around the River Exe has been declared. This also includes an area of the River Teign previously controlled by CD22/2015.
In accordance with the Aquatic Animal Health Regulations (England and Wales) 2009, movements of shellfish from the containment area are now restricted.
Cefas, acting on behalf of Defra, has also applied additional control measures, namely:
- You must apply to the Fish Health Inspectorate for permission if you wish to move any Pacific oysters out of the confirmed designation area, including movements into purification centres (depuration plants).
- You must notify the Fish Health Inspectorate of any increased or unexpected mortality observed in shellfish stocks.
England continues to have OsHV-1µVar control areas in Essex, Kent and Suffolk; Butley Creek; and Poole Harbour.
