To make the food on the table safer, we should establish a perfect traceability food safety guarantee system. This is a systematic process, including food from the farm, food production and processing enterprises, transportation, circulation, table to the consumer's entire process. It has the ability to restore the history of product production and application and its place of occurrence, through which the root cause of food safety problems can be identified and product recall or withdrawal can be implemented in a timely manner. Should then include the following five aspects: 1, record management Catering enterprises for each type of food should be recorded in detail, the establishment of a food database. Health management organization: the procurement and distribution of raw materials , raw materials cleaning, processing, chef, cleaning, service; 2, query management For the food used, are to be numbered and networked, through the input query you can learn about the relevant information about the food. Thus, it can be traced back from the dining table to the food enterprise or farm to understand the complete production, transportation, sales and production process of the food. Food should be checked before purchasing, so that the raw materials are placed on a certain quality assurance. Then number; 3, marking management Food labeling is the most important management information in the construction of food traceability system. Check the quality of food raw materials before processing, spoiled food is not under the pot, not steamed, not baked. Check its labeling information. Its basic function is to be able to track the identification of food, food traceability, in order to prepare for the next processor or consumer query, use; 4, Responsibility Management Through the management of marking, catering enterprises in the case of food safety problems, through the transmission of information about the discovery of problems to determine the responsibility of the relevant business entities, to determine the batch number of the problem food, in stock, transportation and food that has already been sold Saving measures are taken. A traceability system makes it possible to determine which part of the supply chain is at fault and to clearly define the responsibilities of those involved in the different stages of the supply chain. At the same time, it is important to keep a record of the management work in order to understand what happened on the day. Credit management Credit management is an important element of a traceable food safety assurance system. This is the catering company and other production operators in the supply chain must be responsible for the authenticity of the information at that stage. Practitioners at each stage must record the source of the incoming goods at that stage, storage and handling information. They must also inherit the previous production and distribution history and be accountable for these records. If there is a case of counterfeiting, substitution, tampering with labels or records, when tracing the authenticity of the food, it can be traced back from the table upwards to trace out the unsafe food and the practitioners who have violated the law, to implement a product recall and punish the breach of trust according to the law.
