The spread of bluetongue disease is causing a "big issue for beef and sheep farmers" in the South West, according to a farmer. More than 40 animals in Devon and Cornwall have been confirmed to have the Bluetongue virus (BTV) in recent weeks.
England, Wales, Northern Ireland, and the Isle of Man have been placed into a BTV restricted zone. Latest figures indicate 50 cases of the virus have been recorded in England since July 1.
BTV affects cloven-hoofed animals such as cattle, goats, sheep, deer, and camelids, potentially causing ulcers, swallowing and breathing difficulties, fever, lameness, foetal deformities, and stillbirths. The virus is spread by midges, and while Defra has stated it poses no threat to the public or food safety, it can lead to significant animal deaths.
Ian May, South West regional manager for the National Sheep Association, said that while deaths occur, the disease is vaccinatable, and affected sheep and cattle have responded to treatment. Farmers are advised to contact their vet if they suspect BTV on their farm.
Defra has urged farmers to look out for signs including fever, facial swelling, drooling, nasal discharge, lameness, and mouth ulcers, and to report any suspected cases. Penbode Farm Vets in Cornwall reported attending approximately 20 suspected BTV cases in unvaccinated sheep last weekend and recommended vaccinating flocks.
Due to the outbreak, Launceston Agricultural Show in Cornwall announced that cattle and sheep would not attend its show on Thursday to ensure animal welfare and reduce the risk of spreading the virus.
