Application of RFID in Food and Drug Safety Management

　　Application of RFID in Food and Drug Safety Management

　　At present, food and drug safety has become a topic of much concern in our country. An important reason for the continuous occurrence of food and drug safety accidents is that the role of science and technology is insufficient, which is manifested in the lag in the standard work of food and drug safety management; the level of inspection and testing is not high; the technical means to prevent and stop counterfeit sales are incomplete; Problematic food and drug recalls are inefficient

　　In recent years, with the development of computer and network technology, RFID technology has provided a method of uniquely identifying items and has become an effective technical means for item management. Applying RFID technology to food and drug safety management, combined with the corresponding back-end information system, can realize the positioning and tracking of items, and achieve the purpose of food and drug safety management.

　　The way RFID technology is applied to food and drug safety management

　　In the specific implementation process, there are two methods to track the information of the entire food and drug supply chain: one method is tracking from upstream to downstream, called Tracking (Tracking or Trace Forward), which is mainly used to find quality problems. The reason is to determine the origin and characteristics of the product; the other method is to trace back from the downstream to the upstream, which is called tracing (Tracing or Trace Back), that is, when consumers find that the food and drugs they buy have safety problems from the sales link, they can layer by layer. Trace upwards, and finally determine the problem, which is mainly used for the recall of problem products.

　　To apply RFID technology to food and drug safety management, we must first establish a complete and accurate food and drug supply chain information record, that is, to effectively identify and record the products and their attribute information and participant information in the whole process of the food and drug supply chain. . At each processing point in the food and drug supply chain, it is necessary not only to identify the products processed by itself, but also to collect the existing identification information on the processed food and drug raw materials, and mark all of its information on the finished product for preparation. Use by the next processor or consumer.

　　In the food and drug production stage, the producer stores the product name, variety, place of origin, batch, producer information and other necessary content in the RFID tag, and records the initial product information and production process.

　　In the processing stage, the information in the RFID tag is used to sort the products, and only the products that meet the processing conditions are allowed to enter the next processing link. For products entering the processing link, use the information recorded in the RFID tags to deal with different products in a targeted manner. After processing, add the processor information, processing method, processing date, product grade, shelf life, storage conditions, etc. to the label. In the transportation and storage stage, RFID tags and fixed readers installed along the way are used to track the running route and running time of the transportation vehicle. Enter I: 3. Install a fixed reader at the exit to automatically record the entry and exit of the product; use the information recorded in the label to help determine the time when the product is suitable for storage; when leaving the warehouse, select the priority based on the storage time The products of the library; can also realize fast inventory, to help managers to know the inventory status at any time.

　　In the sales stage, merchants or hospitals use RFID tags to understand the status of buyers' products and implement access management for products. At checkout, RFID tags can be used to achieve fast checkout. Merchants or hospitals can write the name of the company, sales time, sales personnel and other information into the label to confirm the product when the customer returns and recalls the product.

　　Since the information of product production, processing, transportation, storage, sales and other links is stored in the RFID tag, when a product has a problem, the whole process can be traced to determine the problematic link and the scope of the problem product. Consumers can also use RFID tags to confirm whether the purchased product has problems and whether it is within the scope of the recall.

　　In addition, while adding information to the RFID tag, the information can be transmitted to a public database. Consumers or purchasing units can compare the content of the tag with the records in the database, thereby effectively identifying counterfeit products.

　　Thus, the application of RFID technology can be completed based on covering the supply chain of food and medicine.

　　The entire process of data records and reliable connections between data and objects can ensure that the sources of food and drugs are clear and can be traced back to the origin of raw materials, as well as all links in the production, processing, and logistics processes.

　　Safety management goals: traceability of the "source" of food and drug safety and transparent management of the food and drug supply chain. At the same time, in order to meet the work requirements of the food and drug regulatory authorities, the government will take the lead to build a food and drug regulatory platform to realize the information access and sharing of related enterprises and departments in all links of the supply chain, and realize end-to-end supervision from the source of production to sales.

　　The risk of RFID application in food and drug safety management

　　1. Lack of unified standards

　　At present, many countries in the world have formulated multiple RFID standards, but there is a lack of unified international standards. If the coding system adopted by the RFID tag is not uniform, or the frequency band used in the entire supply chain is not uniform, it will cause inconvenience in reading and writing, query, tracking and traceability of information, and may even fail to realize the convenience brought by RFID technology. To a certain extent, due to the lack of uniform standards for the application of RFID technology, it is easy to bring obstacles to trade between regions, and also make the safety standards of food and medicine on the market uneven, thereby weakening consumers’ ability to distinguish food and medicine safety. This leads to distrust of food and drugs that use RFID technology to identify.

　　2, the cost is too high

　　Participants in the supply chain need to purchase RFID-related equipment and carry out system infrastructure construction. For some small and medium-sized enterprises, this is a huge expenditure, which also hinders the large-scale application of RFID technology. At present, it can be used on high-value-added products first; for low-value-added products. It can be used in units after packing.

　　3. Benefit distribution

　　Application of RFID technology. On the one hand, it will increase the input cost of related equipment; on the other hand, because the application of RFID technology can improve the efficiency of logistics and transportation links, it can also increase the price of products in the sales link, thereby obtaining benefits. Therefore, from upstream manufacturing and processing manufacturers, intermediate transportation and warehousing companies, to downstream sales terminals, how the participants in the entire supply chain carry out cost sharing and benefit distribution will be one of the main concerns of enterprises in the application of RFID technology.

　　4. Information integrity risk

　　The core of the food and drug safety traceability system is the database. In the entire supply chain, if there is a credibility crisis in a certain link, for example, individual supply chain participants are shoddy or fake, then the data recorded by the RFID tag is meaningless.
