Safeguarding the "safety on the tip of the tongue" requires the joint efforts of all parties. It requires not only the "self-discipline" of production and operation subjects, but also the "heteronomy" of supervision, law enforcement and social supervision. It is also necessary to build a strict and efficient food safety governance system. According to media reports, a fast-food chain brand store recently released a "report on self inspection and self correction" on the Internet, publicizing a total of 18 problems in its stores, and at the same time making a public commitment to effectively correct them, We welcome the supervision of the whole society. This practice has been concerned and discussed by many netizens, many people praise it, and some netizens question it. The popularity of this topic fully demonstrates the importance of food safety in people's minds. Food is the most important thing for the people, and safety is the first thing to eat. There is no trivial matter about food safety. "Safety on the tip of the tongue" connects the majority of producers and operators at one end and the dining tables of thousands of households at the other. The high-quality development of the food industry is an important part of the high-quality development of the economy and society, and food safety is an important livelihood project and popular support project. In recent years, China's food safety supervision has been continuously strengthened, and law enforcement has become more strict. Some major problems in the field of food safety have been gradually solved. Food production and operation enterprises have greatly improved their awareness of subject responsibility, and the concept of co governance and sharing has gradually become popular.

Safeguarding the "safety on the tip of the tongue" requires the joint efforts of all parties. It requires not only the "self-discipline" of production and operation subjects, but also the "heteronomy" of supervision, law enforcement and social supervision to build a strict and efficient food safety governance system.

The enterprise takes the initiative to find out the problems and accept social supervision and rectification, so that people can see the determination and sincerity of the enterprise to ensure food safety. In recent years, the food safety problems exposed by some enterprises have not only harmed the interests of consumers, but also destroyed the brand image of enterprises, which has led to business crisis. The State Administration of Market Supervision recently issued the Provisions on the Supervision and Administration of Enterprises' Implementation of Food Safety Subject Responsibilities, urging enterprises to implement food safety subject responsibilities, strengthening the food safety responsibilities of the main responsible persons of enterprises, and standardizing the behavior of food safety managers. The producers and operators must deeply realize that food safety and sanitation are the "red line" and "bottom line" that can not be challenged by anyone.
