1. System background:
The food quality and safety traceability system is an information management system that can connect production, inspection, supervision, and consumption, so that consumers can understand the production and circulation processes that comply with health and safety, and improve consumers’ confidence. The system provides a traceability model of “from farmland to table”, extracts the public traceability elements that consumers care about in the supply chain links of production, processing, circulation, consumption, etc., and establishes a food safety information database. Once problems are found, they can be traced based on the source. Effective control and recall ensure the legitimate rights and interests of consumers from the source. Continuously monitor the food from the source to the table, form a food safety monitoring database, and conduct risk assessment on the monitoring data. At present, the effect of traditional market supervision is not obvious enough, and government departments need to use information technology to improve the means of administrative law enforcement and enhance the management level. From mad cow disease, foot-and-mouth disease to water-infused meat, poisonous leeks, problematic milk powder, and Sudan Red No. 1, food safety issues are always threatening the health of the people. Solve the adverse effects of food safety issues on the construction of a harmonious society, establish an effective food safety traceability system, find out the links of accidents in the first time, provide the people with food safety warning information in a timely manner, and quickly approve problematic approvals. Sub-food recalls have been the primary responsibility of food supervision departments to protect the health of the general public. It is more urgent to formulate and implement safety monitoring of food programs.
The key technology of food safety traceability is data collection technology. The current data collection technologies used for food safety traceability mainly include one-dimensional bar codes, RFID and two-dimensional bar codes.
2. System overview:
The system is based on the network environment of the government bureau of industry and commerce, including two-level platforms and four subsystems.
The establishment of a city-wide unified central database on the first-level platform is the data management center of the entire system, which will realize the management of traceable data, food recalls, monitoring and early warning, and decision-making analysis within the city. The secondary platform consists of a fruit and vegetable traceability subsystem, an animal product traceability subsystem, a prepackaged food traceability subsystem, and a food traceability subsystem.

4. Food safety traceability principle:
a. In the planting/raising link of primary agricultural products, the traceability unit is determined according to the planting/raising plan, and the planting/raising information is recorded with the traceability unit as the unit. Record the breeding information on the RFID tag, such as putting the ear tag of the RFID tag on the cow when raising the cow.
b. In the process of processing, when the raw materials are checked into the warehouse, the information of the raw materials checked into the warehouse is established to record the raw material inspection and traceability information, and the raw material batches and the planting batches are one-to-one correspondence; during the processing, the raw materials are checked into the warehouse after the processing batch The second is the smallest traceability unit, which records processing information and raw material information in a two-dimensional bar code (or one-dimensional bar code).
C. In the logistics link, take the transport batch as the unit, and read the logistics information in the RFID tag on the box when receiving and dispatching.
D. In the sales link, the smallest retail unit (single product package) is used as the traceability unit, and the two-dimensional barcode (or one-dimensional barcode) is scanned by a scanner or the two-dimensional barcode (or one-dimensional barcode) information is read by the automatic query terminal for traceability. .
