Worst ever outbreak of bluetongue hits British farms

British farms are facing the worst bluetongue outbreak on record, with cases surpassing the total of the last three years. Defra attributes this surge to a hot, humid summer, creating favourable conditions for biting midges. The virus, originating in Africa, has reached Aberdeenshire, affecting cattle and sheep. Symptoms include fevers, ulcers, swollen heads, and lameness, with the tongue potentially turning blue. In severe instances, the disease can lead to the death of the affected animals.
