What are the requirements of food safety traceability system?

The food safety traceability system was first established and improved by the European Union in response to the problem of 1997 "mad cow disease". This food safety management system is promoted by the government, covering the upstream and downstream of the whole food industry chain, such as food production bases, food processing enterprises and food terminal sales. And share information through special hardware equipment similar to bank ATM system to serve the final consumers. Once there is a problem with the quality of food at the consumer end, you can make an online inquiry through the traceability code on the food label to understand all the circulation information such as food production enterprises, food producing areas and specific farmers, and clarify the corresponding legal responsibilities of the accident party. This system is of great significance to food safety and food industry self-discipline.

The establishment of food safety traceability system is promoted by the government and realized through the participation of all parties in the food industry chain. Mainly includes: agricultural products production base, beef cattle breeding base, slaughtering and processing enterprises, food processing enterprises, circulation enterprises, retail enterprises and final food consumers.

The establishment of food safety traceability system depends on the information technology related to the Internet of Things. Specifically, it is to develop all kinds of hardware equipment dedicated to food traceability and apply them to all parties involved in the market and interact through networking, so as to transform, integrate and mine a large number of heterogeneous information, realize food safety traceability information management, and complete information collection, recording and exchange in many links such as food supply, circulation and consumption.

At present, there are three kinds of food safety traceability technologies in China: one is RFID radio frequency technology, which labels food packages with chips, so that products can automatically collect and read relevant information in the process of entering and leaving warehouses and transportation, and record the flow direction of products on the chips; One is the QR code. Consumers only need to shoot the QR code through the mobile phone with camera, and they can query the relevant information of the goods. Query records will be saved in the system. Once the product needs to be recalled, they can send text messages directly to consumers to achieve accurate recall. There is also bar code plus product batch information (such as production date, production time, batch number, etc.). ). In this way, food production enterprises basically do not increase production costs.
