In recent years, food safety crises have occurred frequently, seriously affecting people's health, causing widespread concern around the world. How to effectively track and trace food, has become an extremely urgent global issue, the construction of food safety traceability system has become the world's countries **** knowledge. At present, China's food safety traceability system is still in the trial operation stage, the initial realization of the traceability function, and the realization of the pilot cities and the central platform of the docking, uploading data has been as much as more than 42 million, part of the city's traceability system has been played or is playing a role. "The Fourth China Food Safety Forum" in the recent end, "traceability system construction" has become the focus of attention of this forum. Reporters learned from the forum, China is brewing to expand the implementation of food safety traceability system pilot range. Sources revealed that in 2012, the Ministry of Commerce will select another 15 cities to carry out the third batch of traceability pilot, and strive to cover the conditions of the municipalities directly under the central government, cities and provincial capitals, the initial formation of a large market with the country, a large circulation pattern compatible with the national network structure.

The first batch of pilot results

October 2010, the Ministry of Commerce and the Ministry of Finance **** with the identification of Dalian, Shanghai, Nanjing, Wuxi, Hangzhou, Ningbo, Qingdao, Chongqing, Kunming, Chengdu and other 10 cities as the country's first batch of meat and vegetable circulation of the construction of the traceability system pilot. After nearly 1 year of efforts, these pilot cities are beginning to show the effect, especially Shanghai, Hangzhou, Qingdao and other "leading" cities, is playing a role for the general public can eat meat and vegetables with confidence.

Buy food, pay, figure on a meat and vegetables "ID card", if the quality of meat and vegetables do not feel confident, but also real-time verification, which is the future of Hangzhou and even the country's horse sisters-in-law of the "food court strategy". As the first batch of meat and vegetables traceability system construction pilot city, from December last year, Hangzhou meat and vegetables circulation traceability system construction work has been in Hangzhou city (including Xiaoshan, Yuhang) of the designated slaughtering plant, meat and vegetable wholesale market, supermarket stores, farmers' markets and so on successively start to push open. At present, Hangzhou "meat and vegetable circulation traceability system" has been fully opened, the city's nearly 110 farmers' markets have begun to use the traceability of electronic scales, consumers can be based on the electronic ticket with a traceability code, query to the market name, purchase stalls, seller's name, buyer information, as well as the transaction varieties and time and other information. The most important thing is a string of 20-bit traceability code, as long as the Internet to enter the traceability code (URL:.cn) can be traced back to the origin of meat and vegetables, processing companies, pesticide residue testing and a series of circumstances. The reporter learned from the Hangzhou Municipal Bureau of Agriculture, at present, Hangzhou as a pilot deployment of the traceability system of vegetable production bases have been 45, after all large-scale vegetable bases will enter the traceability system, Hangzhou catering enterprises are also expected to join the "traceability system", *** with the boycott of "problematic Meat and Vegetables".

Shanghai from 2005 onwards to start the pork traceability system, is the pioneer of domestic food safety traceability system. According to information released by the Shanghai Municipal Commission of Commerce, Shanghai's pork traceability has been in the slaughter, wholesale, retail links to achieve basic full coverage, the next five years, vegetables, fruits, aquatic products, food, northern and southern goods and other major agricultural and sideline products traceability system basic full coverage. So far, the city has 730 standardized vegetable markets, 203 supermarkets hypermarkets, 13 pig slaughterhouses, 18 vegetable wholesale markets and other ****1010 enterprises built meat and vegetable traceability system. Consumers can purchase meat, vegetables through the sales terminal electronic scales printed on the electronic label query to the source and processing enterprises, production date, quarantine inspection, circulation links, operators and other information. This year, Shanghai Meat Circulation Traceability System construction and new initiatives, there are 30 food court in the Shanghai area to realize the card to buy food, the public only need to go to the bank or in the designated food court for financial IC card, can be in the 30 food court card to buy food, no need to find change, not afraid of counterfeit money.

Qingdao Meat and Vegetable Circulation Traceability Operation Command Center has recently been put into use, meat and vegetable circulation traceability system will be fully completed by the end of this year, the future can also be realized with Jinan, Weifang meat and vegetable data **** to enjoy the vegetable situation traced back to Weifang fields. With the circulation of meat and vegetables traceability operation command center, city management monitoring and scheduling platform, real-name management, quality testing and remote video online monitoring and supervision system put into use, Qingdao City, in slaughter, wholesale, supermarkets, farmers markets, stores and other circulation nodes traceable terminal has been basically completed within the year the source can be traced back to the direction of the traceability of the responsibility of the circulation of meat and vegetables throughout the traceability of the management will be realized. It is understood that Qingdao has been built in 186 operating units of the meat circulation traceability system, vegetable traceability system is expected to be completed in the third quarter of this year, which will also be the country's first meat and vegetable circulation traceability system, the public's "food basket" will be more secure, rest assured.

Because it is still in the pilot stage, many people do not have a high degree of awareness of the system, many vegetable markets in the information query machine "virtual", most of them in the "sleepy" state, the operators take the initiative to issue a small shopping ticket awareness also needs to be strengthened. The company's business is also in the process of strengthening the awareness of the business.

Meat "identity card" how to generate

With the help of the meat traceability system, so that each vegetable, each piece of meat have their own "identity card", the public can rely on the representation of meat "identity card" of the shopping ticket, the public will not be able to find out what is the best way to get to the bottom of the problem.

With the help of the meat traceability system, each vegetable and each piece of meat has its own "ID card", and the public can rely on the "ID card" of the meat and vegetables to grasp the "ins and outs" of the meat and vegetables purchased. A small shopping ticket, how to get "from farm to table" information. Let's take a green vegetable as an example. This piece of green vegetables from the vegetable base will be tested before production, after passing the test will be labeled with a "quality and safety base allowed to go out of the label," the label comes with a 20-digit traceability code. This one has a "household registration" of the green vegetables to reach the wholesale market, but also have to once again "physical examination", vegetable base and business transactions, the two sides also have to at the same time to brush the card, so that the traceability code on the record will appear on the record of this green vegetables "! Moving" information. By analogy, this green vegetable to Ma's sister-in-law's basket, all the transaction information can be recorded in the traceability code.

In order to further understand the system, the reporter learned from the technology provider about the formation process of the food safety traceability system. First of all, raw material suppliers in the food manufacturers to provide raw materials for batch management, the raw materials of the original production data, including the date of manufacture, the edible period, the origin, the producer, with or without the use of pharmaceuticals and other information into the two-dimensional code, and printing with two-dimensional code of the label, pasted on the box and then handed over to the food manufacturers. When the food manufacturer is warehousing the raw materials, the data collector is used to read the QR code and obtain the original production data of the raw materials, and the data is used to confirm whether the delivered products meet the manufacturer's purchasing standards, and the raw materials that meet the purchasing standards are warehoused.

Food manufacturers make recipes based on the day's production schedule. According to the production plan order, the employees withdraw the necessary raw materials from the warehouse, weigh and subcontract the weight of various raw materials according to the requirements of each batch, and paste labels with QR codes on the subcontracted raw materials, which contain information such as the name of the raw material, the weight, the order of the inputs, and the number of the raw material. According to the instructions of the production plan, the Kanban board with QR code is printed and placed in front of the production line, and the QR code on the Kanban board contains the contents of the work instructions. When the raw materials are mixed, the code on the Kanban board and the QR code on each raw material are read to confirm that the inputs are made correctly according to the production plan and to record the information on the use of raw materials.

After the raw materials are put into each inspection process, the data collector is used to enter the inspection data recorded manually in the past, and the data in the data collector is uploaded to the computer to generate the raw data of the production, which makes it possible to trace the products and raw materials. Once the food is found to be problematic, it can be effectively controlled and recalled according to the traceability to protect the legitimate rights and interests of consumers from the source.
