The issue of food safety in schools is of vital interest to a large number of teachers and students and is a focal point of public concern， which can easily trigger significant negative public opinion on the internet. Adhering to the institutional logic of ‘structure-operation-assurance’， constructing an analytical framework of ‘regulatory body-regulatory methods-regulatory evaluation’ to analyze the current food safety supervision in schools. There are issues such as oversight in the implementation of policies by the regulatory bodies， insufficient capacity to respond to emergencies， an inadequate regulatory system， the need for improvement in the school food outsourcing model， an imperfect performance evaluation system， and a lack of food safety awareness. Based on the analysis of these issues and their causes， and in conjunction with relevant experiences from abroad， including a comprehensive legal system， multi-level regulatory models， strict industry access， severe punishment and penalties， and a focus on campus food safety education and parental participation， the following suggestions are put forward: strictly implement the school ‘first-in-command’ responsibility system， continuously improve the institutional mechanisms for school food safety， continuously improve the school food safety supervision system， focus on strengthening the management of school canteen food outsourcing， build a smart integrated food safety system platform， improve the food safety emergency response mechanism， and strengthen the safety training of school catering industry personnel. These suggestions provide effective strategies for improving the governance of school food safety conditions.
