The UK's chief veterinary officer has called on farmers to remain alert for bluetongue virus (BTV-3) as cases increase in Europe, especially in the Netherlands, Germany, and Belgium. Free testing is available for animals from high-risk areas in Britain. While there are no active cases in England, warmer weather heightens the risk of transmission through biting midges. Farmers should monitor their animals for symptoms and register with the Animal and Plant Health Agency (APHA), which stresses the importance of ongoing surveillance and reporting any suspicions to prevent an outbreak.
