This document discusses the development of a participatory animal health surveillance system in Chiang Mai, Thailand. The system aims to improve surveillance by engaging more people, including farmers, villagers, and consumers. It plans to use smartphones and voice calls to collect reports of abnormal animal situations and product issues. The collected data will then be visualized on a map to help locate farms, markets, and slaughterhouses. The system also seeks to better register all animal farms and provide online education about animal health and food safety to the public. An initial demonstration of the solution's design was presented.
