The role of RFID technology in food safety

　　In the livestock tracking system, RFID can trace or track the movement and activities of livestock in real time during the entire life cycle of the animal, from the farm to the slaughter and processing plant, and even to the final consumer when necessary.

　　The key to this system is the unique identification method. This method (PIDC) is an accurate location identification method, which is identified according to the unified asset code around the world, no matter if these places are feedlots, pastures, auction houses, processing plants, animal delivery points. The database of the system can serve various regions and be connected with other asset identification codes to provide the flow of livestock from one region to another, as well as the dynamic location of livestock throughout the country and around the world.

　　Relying on this precise location identification method, RFID solutions can ensure high-quality data exchange in any supply chain, allowing the food industry to achieve the two most important goals. First, thoroughly implement the "source" food tracking solution. Second, the ability to provide complete transparency in the food supply chain.

　　The RFID system can provide a reliable connection between food and its source in the food chain, ensuring that the source history of food arriving at supermarket shelves and restaurant kitchens is clear, and can be traced to specific animal or plant individuals and farms. RFID is a solution for 100% tracking of the source of food, so it can answer user questions about "where does the food come from, and whether the intermediate processing link is complete?" and provide detailed and reliable answers. It can effectively monitor and solve food safety issues.

　　To obtain animal health information, using this system does not have to wait hours or days, and all the latest data on the spot will be displayed in real time immediately. No matter when and where, whether it is in the wild, auction house, feedlot, or processing plant or other places, as long as the data is collected and uploaded, it can be provided immediately. Only RFID systems can reach this level and can provide reliable information within a few seconds to meet the demand for information during catastrophic events. Other information about the animal can also be provided when necessary, such as tag information, branding or photos hung on the ears. When the RFID tag on the ear is lost, stolen, or only the unique identification characteristics of the animal can be identified, the system will provide a new means of identification.

　　The RFID database is network-based, using reliable connections to the Internet and monitoring livestock flow detection point systems, providing real-time traceability services, and providing records of the entire flow process of animals from breeding to production. This backtracking service for agricultural and livestock products is very reliable. Qualified users, including producers and consumers around the world, can use this service when necessary.

　　And its on-site data collection system can record all animal activities, including its ID and current location. People's actions against animals at a certain time on a certain day are recorded, including birth, vaccination, treatment, breeding, sale, transportation, etc., to ensure accurate and reliable livestock identification in the system. We can clearly know how cows and other livestock are fed during the breeding period, so that we can better know whether the meat and poultry we eat are safe.

　　This system includes various animals and livestock, such as beef cattle, dairy cows, horses, pigs, sheep, goats and various wild animals and domesticated animals (such as deer, elk, alpaca, ostrich, bison, poultry, fish, etc.), It also includes all markets and industry sectors, forming a complete food monitoring chain including producers, auction and market operators, various sellers, breeders, transporters, processing plants, wholesale retailers, etc.

　　The network-based system collects and records special data, such as the animal's RFID number, the address number of the RFID reader that reads the animal's passage, and the precise time of reading. Then the data is transmitted through the network in a certain format, and the relevant personnel can see the results on the screen within a few seconds. This data collection and reporting system uses the nationwide telephone line system for real-time transmission, and transmits data from the RFID reader to the network server at a high speed and accurately, with very low cost.
