Call for owners to play ‘crucial’ role in equine grass sickness research
Owners of horses who have been affected by grass sickness are being urged to take part in a “crucial” new project to help protect equines from the devastating disease.
A new “biobank” has been formed, containing samples from horses and soil samples, that will play a role in future grass sickness research.
The project has been created by livestock health and welfare research charity Moredun Foundation and the Equine Grass Sickness Fund, with support from the British Horse Society (BHS).
“A lack of suitable samples from [equine grass sickness] cases has hindered research progress into the causal agents involved, despite the disease being recognised for over 100 years,” said a joint statement from those involved in the project.
“But horse owners and vets can now play a crucial role in this project by submitting samples from affected horses and field controls, along with soil samples, to the new biobank.
“In future, scientists researching [the disease] will be able to apply to use the anonymised samples in projects aiming to establish the causal agents and break new ground against the disease.”
Equine grass sickness has an 80% fatality rate. It can occur at any time of year, but is found to be most prevalent between April and June.

“By donating samples and completing case questionnaires, horse owners and vets can provide valuable information helping researchers understand the risk factors and protect future generations of horses and their owners from the terrible effects of this disease,” added the statement.

Dr Beth Wells, principal scientist and knowledge exchange specialist at Moredun, said the charity is delighted to be working in partnership with the Equine Grass Sickness Fund to develop the national biobank.
“This is essential for research to progress and the samples will be available to all researchers,” said Dr Wells, thanking the BHS for its “generous funding”.
“We are very grateful to all the horse owners and vets who have already provided samples, at such a difficult time for them, and we urge everyone to think about supporting us to help find the cause of this devastating disease.”
