Food safety is a global problem and one of the challenges facing China. According to the importance of the problems, the main food safety problems in China at present are: food-borne diseases caused by microorganisms; Chemical pollution caused by pesticide residues, veterinary drug residues, heavy metals, natural toxins and organic pollutants; And illegal use of food additives. As a developing country in the stage of rapid economic development, China's food safety problems have their own characteristics. First, old and new problems coexist. Due to the poor conditions of food production, processing and operation, backward technology or failure to comply with hygienic operation rules, food is polluted by microorganisms and heavy metals. For a long time, these old problems will be difficult to be fundamentally solved. At the same time, with the rapid economic development, some new problems faced by industrialized countries have emerged in China. Second, the source pollution is outstanding. At present, more than 2 million farmers in China are producing primary agricultural products in a decentralized way, including the grain, vegetables, fruits, chickens, ducks, fish and eggs, all of which are produced by farmers. With the knowledge of food safety and the awareness of abiding by the law, it is inevitable that pesticide residues in vegetables will exceed the standard. Third, the majority of small and medium-sized food processing enterprises determine the poor level and quality of food processing industry. At present, most of the nearly 5, food production enterprises are small and medium-sized enterprises. With the quality of these employees, it should not be surprising that microbial indicators such as products exceed the standard and food additives are used excessively. Fourth, the communication channels of food safety information are not smooth. Scientists and government departments do not report food safety information in time. The media's imprecise and inaccurate negative reports and news hype on food safety issues have made consumers very sensitive to food safety issues, so that people have complained: "What can we eat now!" There is no denying that the current situation of food safety in China is not satisfactory, and there are still many problems, some of which are still outstanding; But the situation is by no means as bad as people think. The root of this false impression lies in people's misunderstanding of food safety in many degrees. First, consumers demand "zero" risk of food safety. People generally think that the traffic risks brought by driving a car and flying are acceptable, but even if there is a little risk in food safety, consumers think it is unacceptable. This kind of mood is understandable, but it is unscientific, because "zero" risk does not exist. Second, too much attention is paid to chemical pollution and food-borne diseases are ignored. Food-borne diseases are the number one food safety problem in the world and in China, but they are often ignored. Instead, chemical pollution is put in the first place. In fact, the possible harm of illegally adding Sudan red Chili sauce to human health is far less than a diarrhea caused by eating bad. Third, equating the fake and shoddy food with food safety in a general way virtually exaggerates the food safety problem. Confusing the two will interfere with the solution of the problem, because counterfeiting and food safety should be solved by different government departments. Fourthly, the food contaminated by carcinogens is equated with carcinogenic food. There are many foods containing carcinogens. The skin of charcoal kebabs and Beijing roast duck both contain carcinogen benzopyrene, but it does not mean that eating kebabs and Beijing roast duck will lead to cancer. Fifth, it is considered that unqualified food is equal to toxic food. Products do not meet food hygiene standards and should be banned, taken off the shelves and recycled, but this does not mean that they will be poisoned if eaten. In the end, how should we treat food safety problems and what methods should we adopt to solve them? Now the mature and recognized law in the world is "risk analysis framework". This framework consists of three parts: risk assessment (expert behavior), risk management (government behavior) and risk information exchange (all stakeholders). If we can follow the framework of risk analysis, people can form a correct and scientific understanding of the food safety problems they face; Then make management decisions based on science and suitable for national conditions.
