At present, although my country’s total meat production ranks first in the world, the output of cooked meat products in my country accounts for less than 10% of the total meat output, while the meat products of developed countries have accounted for more than 50% of the total meat output during the same period. . Obviously, there is still a considerable gap between China’s meat product industry and foreign developed countries, which shows that China’s meat product production and marketing industry has a broad space for development. According to the “Tenth Five-Year Plan of the National Food Industry and Recommendations for the 2010 Development Plan”, during the “Tenth Five-Year Plan” period, my country’s food industry will implement products that “turn people into small, thicker into refined, mature into ripe, and waste into treasure”. Adjust the policy, vigorously develop meat products for direct consumption, and gradually increase the proportion of meat products in meat consumption. In the long run, the development potential of my country’s meat products industry is great.

However, in recent years, various meat safety issues, such as mad cow disease, clenbuterol, streptococcus suis infection, avian influenza, antibiotic residues, hormones and preservatives, etc., have been closely monitored by the agricultural and health departments of the world. Important work. China’s meat quality and safety issues have also received extensive attention from governments at all levels and the whole society.

After my country’s accession to the WTO, it means the all-round development of China’s agriculture. How to bring the quality of Chinese meat products closer to international standards, cultivate and strengthen the advantages of Chinese agricultural products in international market competition, improve production quality, production efficiency, and reduce production costs. It is an inevitable requirement to enhance the competitiveness of products and the scope of competition.

China is the world’s largest producer of animal husbandry, but China’s share of the world meat export market is quite low. One of the main reasons is that foreign countries are not assured of the safety of Chinese meat. China’s meat safety management generally adopts terminal inspections. However, there is a serious lack of effective monitoring and management of feeding, slaughtering, processing and other processes, and it is impossible to track and trace the quality of its products quickly and accurately, which increases the risks of enterprises and society.

Since 2003, China has begun to apply advanced RFID radio frequency identification technology to modern pig slaughter and processing enterprises, and has developed a real-time production monitoring and management system for RFID pig slaughter. The system can monitor the entire production process in real time, automatically, real-time, and accurately collect relevant data on key links such as soil production procedures, sanitary inspection, and quarantine, which satisfies the HACCP quality supervision requirements. In addition, government regulatory agencies can effectively monitor product quality and safety through this system, track and trace the source and flow of problematic products in a timely manner, and standardize the production and operation process of meat companies, thereby effectively improving the quality and safety of meat products.

In response to the current strong requirements for food safety tracking and tracing in various countries, the RFID identification system can be effectively used, and it can even be made into a global unified identification and general business standard. It can provide value-added services to supply chain participants and related users. The efficiency of the entire supply chain can play a very good role in promoting food safety tracking and tracing. RFID solutions can ensure high-quality data exchanges in any supply chain, allowing the food industry to achieve the two most important daily standards. First, thoroughly implement the “source” food tracking solution. Second, the ability to provide complete transparency in the food supply chain. To apply RFID to food safety management, RFID must be inserted from its source. Here, we will explain the specific ways of applying RFID from the two target levels of the RFID solution:

1) The company adds RFID Tag to the source of the food or raw material, and writes the basic information of the food or raw material at the source, such as the place of production, date of production, storage method, and eating method.

2) The goods from the place of origin arrive at the food processing plant. At this stage, the processing plant writes the processed or packaged information.

3) Writing of quarantine information and warehousing information of the Quarantine Bureau.

4) Outbound distribution to local agencies, until supermarkets, catering, fast food and restaurants, and then write this level of information into the last link of the tracking chain.

5) Finally the food arrives at the table. Through this process, each link of the food can be traced from the entire chain.

In the specific implementation process, there are two methods for tracking using RFID food tags: one is tracking from top to bottom, that is, from the farm, the food raw material supplier—plus the merchant—the transporter—the seller—the POS point of sale. The method is mainly used to find the cause of the quality problem and determine the origin and characteristics of the product. The other is to trace from the bottom up, that is, when the consumer finds a safety problem in the food purchased at the POS point of sale, he can proceed to the upper level. Trace back to finally determine the problem. This method is mainly used for the recall of problem products. The RFID system provides a detailed and unique perspective of the supply chain by providing a separate identification and storage and transportation history for each item, achieving the above two goals. In actual closed-loop applications, RFID can be combined with barcodes at this stage. The use of “RFID+Barcode” technology can improve the traditional working mode, realize the full-process control and traceability of products by breeding companies, and develop a complete industrial chain food safety control system.

Achieving food safety is the core of the project, which is to integrate the “RFID + barcode” technology throughout the food safety (boar breeding-breeding-slaughter-segmentation-small packaging-transportation-dining table), the entire process strictly controlled industrial chain, forming a closed-loop production of the enterprise , To ensure to provide high-quality assured meat to the market. For example, in the stage of pig raising, the RFlD chip is used to replace the original ear ring, and when the pig is slaughtered and put on the market, the pork packaging uses barcode technology. Why do cows and pigs use RFID instead of bar codes? Because pigs move every day, bar codes may be rubbed off. And RFID can be recycled and reused after slaughter. And the pork being sold-once there is a quality problem. According to the barcode of the pork packaging, the whole process can be tracked and supervised.

The use of RFID technology and information technology to realize the monitoring and management of the entire process of feed, breeding, breeding, slaughter, processing, distribution, retail, and timely tracking and tracing of information is the only way for the world’s meat and food safety management and development direction . It is extremely long-term and important for improving meat production quality and safety, circulation control, safe consumption, protecting consumer rights, increasing farmers’ income, and enhancing the competitiveness of my country’s meat and agricultural products in the globalized market environment of global agricultural products markets. significance.

For the busy fast food industry, because a large number of food supplies require easy-to-use automation solutions, Liu’s high-efficiency supply chain system is very fast and accurate. The fast food industry is extremely demanding on logistics management due to the highly intensive working environment and the need to strictly control costs. The inherent powerful management functions of the RFID solution can just meet the requirements of fast food stores and accounts. Take fast food pork as an example to illustrate the implementation case: for a pig that comes to a company’s breeding base, it can be traced not only to some details of a pig itself, but also to its parent and parent, as well as the input of feed and medicine in the breeding process. . If it is found that the male parent and female parent of this pig have an epidemic, or the feed or medicines input during the raising of this pig have problems, the RFID system can be used for tracking and tracing. As long as we sign agreements with supermarkets and other chain stores, we can track and trace the safety and quality of pork products throughout the entire process. Even if there is a quality problem in any part of the pork product in the future, it can be immediately traced back to which pig has the problem, so as to minimize the loss caused by food quality and safety incidents.

During the breeding period, each pig is added with an RFID tag. This tag is like its ID card and will remain unchanged for life. The label records which province, city, county, township, and village the pig comes from, the name of the breeder, the name of the farm or the name of the self-employed, and the number of the quarantine certificate. The basic information of each pig is written in a certain period of time. After entering this RFID tag, when entering the slaughter process, it will be entered at the entrance of the channel and the slaughter workshop and the segmentation workshop will also write the RFID tag, and connect this information with the network. This RFID food label includes breeding information, bar code information formed in the slaughter workshop, manufacturer information supplemented by the segmentation workshop, and other product information such as quarantine information. According to this label, the “source” of the food can be traced and the transparent management of the tracking chain can be realized.
