As a new supervision mode, intelligent supervision is being explored in the field of food safety in China. By integrating modern information technologies such as big data, cloud computing, the Internet of Things and artificial intelligence, intelligent supervision aims to realize the whole-process monitoring, risk early warning and efficient response to food safety. This study aims to explore the application and prospect of smart supervision in the field of food safety. By integrating modern information technology, smart supervision can effectively improve supervision efficiency, reduce food safety risks, and enhance public confidence in food safety. At the same time, for the challenges faced by smart regulation, this paper discusses how to improve the legal and regulatory framework of smart regulation, strengthen technological innovation, enhance public participation, and how to build a multi-participation regulatory mechanism to ensure the healthy development of smart regulation in the field of food safety in China.
