A Bluetongue control zone has been declared in an area of East Riding, Yorkshire, as more cases emerge beyond East Anglia, where restrictions are already in place to control the outbreak.
The virus - which can be fatal to sheep and cattle although severity of symptoms vary - was first discovered this season at Haddiscoe, south Norfolk, on August 26.
Other cases followed near Norwich and Lowestoft and a restriction zone was extended to cover the whole of Suffolk, Essex, Norfolk and a part of Greater London.
However, on September 4 a bull in Withernsea, East Riding, was found to have BTV-3 and a 20km temporary control zone imposed on cattle, sheep and other ruminants around the area.
Surveillance in the Yorkshire zone resulted in a further case being found yesterday (September 10).
