Atypical myopathy (also known as seasonal pasture myopathy) is a highly fatal muscle disease in horses in the UK and Northern Europe. This distressing disease results in degradation of respiratory, cardiac (heart) and postural muscles. Affected horses show signs of weakness, muscle trembling and pain, and even with intensive veterinary and nursing treatment, the majority of affected horses will die. To make things worse, multiple horses from one field or yard can be affected. The best way to minimise your horse’s risk of atypical myopathy is to reduce the chance of them ingesting sycamore seeds.
