Equine Surveillance in Canada

Creating awareness of equine health in Canada

EQUINE STAKEHOLDER MAP

The Equine Surveillance Network links the diverse equine community to encourage and support integrated and whole-of-system equine health surveillance. It ensures timely information of equine disease occurrence is available to help inform better decisions to protect the health and well-being of horses and humans. Effective and responsive equine health surveillance safeguards the prosperity of Canada’s equine industry and enables the movement and continuance of trade.

The Equine Surveillance Network is part of the Canadian Animal Health Surveillance System (CAHSS), which connects animal health, public health and wildlife health experts from Canada’s animal sectors. In addition to the Equine Surveillance Network, CAHSS member networks include poultry, swine, aquatic, and dairy cattle. CAHSS members work on diseases and issues of concern, including reportable and zoonotic diseases, production limiting diseases and antimicrobial use surveillance.
