British farmers face the worst bluetongue season on record, with Defra recording 2,201 cases for the current season so far, according to theguardian.com. The viral disease affects sheep and cattle, causing fevers, ulcers, swollen heads, lameness, and occasionally death via biting midges transmitting serotype 3 (BTV-3).
Record 2,201 Cases Recorded Across UK Farms
The current bluetongue season runs from July 1, 2026, to June 30, 2027. Despite being only three months old, the season has already surpassed the total number of cases from the past three years combined. Defra recorded 1,103 cases in September alone. A case is defined as a premises with at least one infected animal, meaning the total number of affected livestock is likely higher than reported cases. The disease has crossed into Scotland for the first time this summer, appearing as far north as Aberdeenshire.
Vaccine Shortages Create Labor Pressures for Farmers
Livestock producers can vaccinate animals against the virus, but Robyn Munt, vice-president of the National Farmers’ Union, stated that obtaining the vaccines has proved very challenging due to a demand-led process. Farmers carried unexpected costs from summer droughts. Munt noted that managing vaccinations and treating infected animals adds more labour pressure and stress to farm businesses.
Climate Crisis Drives Midge Migration Northward
The World Organisation for Animal Health links the spread of the African-origin virus over the past two decades to climate breakdown. Tom Cantillon, a senior analyst at the Energy and Climate Intelligence Unit, described the outbreak as a harbinger of things to come as milder winters and hotter summers allow pests to survive further north. Bluetongue does not affect humans or food safety.
