Strangles cases in horses have increased across the UK in 2026, prompting experts to urge owners to maintain vigilance and biosecurity measures.
By 23 June, 274 cases had been recorded through the Surveillance of Equine Strangles programme. The cases span Northern Ireland, Scotland, Wales and much of England.
If current diagnosis rates continue, projections indicate around 600 confirmed cases for the full year. This would represent a rise of nearly a quarter compared with 2025.
Helen Whitelegg of Redwings noted that just over a third of the recorded horses showed clinical signs of illness. She stressed the importance of the BEST protocols, including vaccination to boost immunity, separating unfamiliar horses and routine temperature checks.
Vet Mary Battersby of Dechra added that both strangles and equine flu spread rapidly. She said good biosecurity and preventative measures remain essential, particularly during the summer when owners are often more active with their horses.
