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 recalls protect 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 traditional market supervision effect is not obvious enough, and government departments need to use information technology to improve the means of administrative law enforcement and improve the management level. From mad cow disease, foot-and-mouth disease to water-infused meat, poisoned leeks, problematic milk powder, and Sudan Red No. 1, food safety issues are threatening the health of the people at all times. 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 early warning information in a timely manner, and quickly approve problematic approvals. Sub-food recalls to protect the health of the general public is already the primary responsibility of the food supervision department, and it is more urgent to formulate and implement safety monitoring of food programs.
The key technology for food safety traceability is data collection technology. Currently, the data collection technology used for food safety traceability is mainly one-dimensional bar code.RFIDAnd a two-dimensional barcode.
2. System overview:
The system is based on the network environment of the government’s industrial and commercial bureau, 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 city-wide traceability data management, food recall, monitoring and early warning, and decision-making analysis. 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.
3. 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 processing link, when the raw materials are checked into the warehouse, the raw material checking and receiving database information is established, and the raw material inspection and traceability information is recorded, and the raw material batches and the planting batches are one-to-one correspondence; during 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 bar code (or one-dimensional bar code) is scanned by the scanner or the two-dimensional bar code (or one-dimensional bar code) information is read by the automatic query terminal for traceability.
