Why do I need to get my mare EVA (Equine Viral Arteritis) tested?
EVA can cause enormous problems when transmitted to pregnant mares and stallions. All mares and stallions entering studs should be EVA negative or EVA vaccinated (annually) in order to ensure that EVA is not introduced to the resident and/or visiting population at a stud. It is a notifiable disease under UK law, and farms/studs found to have horses with EVA will be quarantined by DEFRA.
