Strangles (Streptococcus equi) has been confirmed in Dufferin County, Ontario. A 15 year old Draft gelding developed white discharge from both nostrils and a high fever on January 27, 2026. A new horse had been purchased two weeks prior to this horse developing signs. The new horse seemed "off" and was isolated just prior to this gelding becoming ill.
The facility owner, working with their veterinarian, has instituted voluntary animal movement restrictions and biosecurity protocols. To see past and present Strangles cases in Ontario go to: https://www.oahn.ca/resources/ontario-equine-disease-alerts/ and enter the disease surveillance portal.
