Western Canada's support for Swine Health and Disease Surveillance


CWSHIN serves western swine producers, swine herd practitioners and governments to improve swine health, production, and the economic prosperity of the sector.

Our vision is to have a surveillance system imbedded in an intelligence network that monitors diseases both present and absent.

The core of the surveillance system is the quarterly conference calls which bring together swine herd veterinarians and swine health experts in western Canada. Prior to the calls, CWSHIN collects clinical impression surveys completed by practitioners, laboratory data and other publicly available data such as federal inspected abattoir data. The data is then analyzed and presented for discussion during the calls.
