“Food is the heaven for the people, and safety is the first.” The application of RFID technology in the safe food supply chain will help food companies strengthen food safety management, stabilize and expand consumer groups, and enhance market competition. From the perspective of the food supply chain, it creates an environment for consumers to consume with confidence, establishes a good image, and effectively improves the service level of the entire supply chain. Although there are still some problems to be solved in the application of RFID, its application prospects are very broad.
1. Issues in food safety
In recent years, my country has entered a period of frequent food safety incidents. Food safety issues were listed as one of the top ten hot issues in China’s business in 2009. Avian influenza, foot-and-mouth disease, inferior milk powder, poisonous dumplings incident in Japan, and the recent poisonous cowpea incident in Hainan… Point. Food safety still has problems such as exceeding standards, lack of laws and regulations, testing and environmental protection systems, and unsound regulatory traceability information platforms. Consumers have low confidence in the safety of any type of food. The successive food safety issues are severely damaging people’s dietary confidence…What happened to Chinese food? What else can we eat tomorrow? How to find effective tracking, management, tracing, and assessment methods to ensure safety is an important issue that China is currently facing urgently to solve on food safety issues.
1. Consequences caused by food safety issues
Affecting international trade Food safety is an important condition for food trade between countries, and it is also an important cause of trade disputes. According to reports, every year a large number of exported foods in my country are seized due to food contamination, pesticide residues, and additives that do not meet sanitary requirements.
Affecting the survival and development of enterprises The food industry occupies an important position in my country’s national economy. Food safety is the foundation of food brands and the life of food companies. Ensuring food safety is the first eternal theme of the survival and development of food companies. Once a food safety problem occurs, the company will immediately fall into trouble and become unsustainable.
Public health factors that affect food safety, food itself, animals and plants in nature, and some natural ingredients are toxic and harmful substances. All kinds of food that people eat are produced, processed, packaged, stored, transported, and sold. Contaminated by toxic and harmful substances, artificially added additives added to food to improve food quality, color, aroma, taste, as well as the needs of anti-corrosion and processing technology, there are many types and quantities of additives, which are abused. The interests of some lawbreakers are intriguing, and they are maliciously mixed with falsehoods in order to make huge profits. Cause serious food safety problems. Illegal production and operation cause important hidden dangers to food safety issues.
In the current food industry, food needs to go through a series of processing, transportation and storage links from production to final consumption. If any loopholes occur in any link, the food may be in an unsafe state, such as contact with sources of infection or storage. Improper food spoilage. RFID technology provides an effective technical way to solve this problem, using it to realize food safety management, traceability and evaluation.
RFID is a non-contact automatic identification technology. It uses radio frequency signals to automatically identify target objects and obtain relevant data. Combined with an effective database system and network system, it can achieve global tracking and information sharing of items. RFID technology has the advantages of no manual intervention in identification work, remote reading in batches, low environmental requirements, long service life, data encryption, and changes in storage information. Its application will bring essential changes to food safety traceability management.
2. Application of RFID technology in food safety management at home and abroad
A cattle tracking system has been established in Europe. In September 1998, the United Kingdom announced a cattle tracking system plan. By the end of 1999, all member states of the European Community had implemented this system plan. The British government stipulated that July 1, 2000. Cattle born or imported after the following day must use an identification system, and RFID electronic tags must be installed within 20 days of birth to record the birth, import, activities, vaccines, diseases and deaths of each cow. With the economic benefits of the application of RFID technology in European food safety management, in June 2001, European customers began to emphasize the convenience of logistics transportation and traceability of fresh agricultural products, and required the use of EAN/UCC-128 on packaging. Barcodes were promulgated in the European Food Safety Act in January 2005, and the traceability requirements for fresh foods came into effect. New Zealand kiwi fruit was approved for sale on European supermarket shelves in 2005. In 2003, the United Kingdom implemented the identification standard for pigs. On January 1, 2008, European regulations compulsory electronic identification of sheep.
3. The application of RFID technology in food safety management in my country
In my country, RFID technology has also been applied to food safety tracking management, and has received strong support from many local governments. In May 2002, the Ministry of Agriculture issued the “Administrative Measures for Animal Immunization Labeling” stipulating that pigs, cattle, and sheep must wear immune ear tags. Establish an immunization file management system. The “Food Safety Early Warning and Origin Traceability Control System for Hong Kong Supply” implemented in Shenzhen and Hong Kong. In order to ensure the safety of food supply to Hong Kong, the system adopts RFID radio frequency identification technology for Hong Kong food breeding, production, processing, transportation, wholesale, and ports. Various links such as inspection and retail. Attaching RFID electronic tags to the outer packaging of food contains food inspection information, food growth, production information, storage, transportation and packaging information. Hong Kong citizens can trace the origin of the food and other information through the electronic tag reader. More at ease. In Shandong Shouguang Vegetables, in the province, with the help of the golden engineering network platform of the Shandong Provincial Quality Supervision System, a provincial food safety and quality database has been established to provide consumers with dynamic and authoritative food quality traceability information. Sichuan pig breeding and Zhejiang aquatic product export have successively established RFID traceability systems for food safety management, which effectively guarantees local food safety supervision. These pilot projects have greatly promoted the establishment of my country’s food safety traceability system.
