Since its inception in 1988 The Moredun Foundation Equine Grass Sickness Fund has supported research projects which aim to:

  • establish the cause of grass sickness
  • develop a method of prevention
  • facilitate diagnosis
  • improve the treatment of chronic cases
  • investigate relevant aspects of the pathogenesis

The main line of investigation at present is the role of soil borne Clostridium botulinum type C as the cause of grass sickness. If it can be proved that EGS is caused by toxico-infectious botulism this would enable owners to protect their horses from EGS by vaccination in the future.


EGSF will continue to fund research projects by vets and scientists using the most advanced technology, until the disease can be prevented.
