Samples taken from the affected site were confirmed as positive for oyster herpesvirus (OsHV-1 µvar), and a new Containment Area Covering the tidal waters within the River Teign has been declared.
In accordance with Commission Regulation 175/2010, movements of shellfish out of the Containment Area covering the River Teign, have been restricted, following the confirmation of oyster herpes virus (OsHV-1 µvar).
