On June 3, 2020, the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) was notified of a confirmed case of equine herpes myeloencephalopathy (EHM) due to equine herpes virus-1 (EHV-1) at a boarding facility in Durham County.
Results of laboratory testing confirmed the presence of EHV-1. The horse, a 18-year-old quarter horse gelding, is being isolated and treated at an equine referral hospital.
The farm manager along with the attending veterinarian have restricted movement for horses and people on and off the property and instituted strict biosecurity procedures including twice daily temperature recordings for all horses on the property. There is no link between this facility and the racetrack in the City of Toronto and the farm in Dufferin County for which previous advisories were issued.
