In recent years, food safety crises have occurred frequently, which have seriously affected people's health and attracted worldwide attention. How to track and trace food effectively has become an extremely urgent global issue, and the construction of food safety traceability system has become the knowledge of all countries in the world. At present, China's food safety traceability system is still in the trial operation stage, and the traceability function has been initially realized, and the docking between pilot cities and the central platform has been realized. More than 42 million pieces of data have been uploaded, and the traceability system in some cities has played or is playing a role. The 4th China Food Safety Forum ended recently, and the construction of traceability system became the focus of this forum. The reporter learned from the forum that China is planning to expand the scope of implementation of the pilot food safety traceability system. It is revealed that in 20 12, the Ministry of Commerce will select 15 cities to carry out the third batch of retrospective pilot projects, and strive to cover qualified municipalities directly under the central government, cities with separate plans and provincial capitals, and initially form a national network framework that is suitable for the national market and circulation pattern.

The first batch of pilot results are beginning to appear

20 10 year 10 month, the Ministry of Commerce and the Ministry of Finance jointly identified Dalian, Shanghai, Nanjing, Wuxi, Hangzhou, Ningbo, Qingdao, Chongqing, Kunming, Chengdu, etc. 10 city as the first batch of pilot projects for the construction of meat and vegetable circulation traceability system in China. After nearly 1 year's efforts, the effects of these pilot cities have begun to show, especially the "leading" cities such as Shanghai, Hangzhou and Qingdao, which are playing a role in helping the general public to eat meat and vegetables with confidence.

Buying food, paying money and putting on an "ID card" of meat dishes can be verified in real time if you are not at ease about the quality of meat dishes. This is the "food market strategy" for Ma Daxie in Hangzhou and even the whole country in the future. As the first batch of pilot cities for the construction of traceability system for meat and vegetables in China, since last year1February, the construction of traceability system for meat and vegetables in Hangzhou has been launched in designated slaughterhouses, wholesale markets for meat and vegetables, supermarkets and farmers' markets in Hangzhou (including Xiaoshan and Yuhang). At present, Hangzhou's "meat and vegetable circulation traceability system" has been fully opened, and nearly 1 10 farmers' markets in the city have begun to use traceability electronic scales. Consumers can query the market name, purchase booth, seller's name, buyer's information, transaction type and time according to the electronic receipt with traceability code. The most important thing is a string of 20-digit traceability codes, which can be traced back to the origin of meat and vegetables, processing enterprises, pesticide residue detection and a series of situations as long as you enter the traceability code (website:. cn) online. The reporter learned from Hangzhou Agriculture Bureau that at present, there are 45 vegetable production bases in Hangzhou that have deployed traceability system as a pilot. In the future, all large vegetable bases will enter traceability system, and catering enterprises in Hang Cheng are expected to join the traceability system one after another, resisting "problem meat dishes".

Shanghai has started the pork traceability system since 2005, and it is the pioneer of domestic food safety traceability system. According to the information released by the Shanghai Municipal Commission of Commerce, the pork traceability in Shanghai has basically achieved full coverage in slaughter, wholesale and retail. In the next five years, the traceability system of major agricultural and sideline products such as vegetables, fruits, aquatic products, grain and northern and southern goods will basically be fully covered. Up to now, there are 730 standardized vegetable markets, 203 supermarkets, 13 pig slaughterhouses, 18 vegetable wholesale markets and other enterprises in the city that have established the meat and vegetable traceability system. Consumers can inquire about the sources of meat and vegetables, processing enterprises, production dates, quarantine inspection, circulation links, operators and other information through the electronic tags printed on the electronic scales of the sales terminals. This year, there are new measures in the construction of meat and vegetable circulation traceability system in Shanghai. At present, 30 food markets in Shanghai have realized the use of cards to buy food. Citizens can buy food at these 30 food markets by swiping their cards at banks or designated food markets, without change and fear of counterfeit banknotes.

Qingdao meat and vegetable circulation traceability operation command center has been put into use recently, and the meat and vegetable circulation traceability system will be fully completed and operated before the end of this year. In the future, meat and vegetable data can be shared with Jinan and Weifang, and the vegetable situation can be traced back to the fields in Weifang. With the use of the meat and vegetable circulation traceability operation command center, urban management monitoring and dispatching platform, real-name management, quality inspection and remote video online monitoring and supervision system, the traceability terminals of circulation nodes such as slaughter, wholesale, supermarkets, farmers' markets and specialty stores in Qingdao have been basically completed, and the traceability management of meat and vegetables circulation will be realized within the year. It is understood that Qingdao has built a meat circulation traceability system in 186 business units, and the vegetable traceability system is expected to be completed in the third quarter of this year, which will also be the first meat and vegetable circulation traceability system in China, and the citizens' "food basket" will be safer and more secure.

As it is still in the pilot stage, many citizens have low awareness of this system, and the information inquiry machines in many vegetable markets are "in name only", and most of them are in a state of "sleeping". The awareness of business owners to issue shopping receipts on their own initiative needs to be strengthened.

How to generate "identity card" for meat and vegetables

With the help of the meat and vegetable traceability system, every green vegetable and meat has its own "ID card", and citizens can grasp the "ins and outs" of the purchased meat and vegetables with the shopping receipt representing the "ID card" of the meat and vegetables. How to get the information "from farmland to dining table" on a small shopping receipt. Let's take a vegetable as an example. This vegetable will be tested before it is produced from the vegetable base. After it is qualified, it will be labeled with a "Quality and Safety Base Permit Label" with a 20-digit traceability code. After this vegetable with the hukou book arrives at the wholesale market, it has to undergo a "physical examination" again. When the vegetable base trades with the business households, both parties have to swipe their cards at the same time, so that the "moving" information of this vegetable will appear on the record of the traceability code. By analogy, all the transaction information can be recorded in the traceability code before this vegetable reaches Mrs. Ma's vegetable basket.

In order to further understand this system, the reporter learned about the formation process of food safety traceability system from technology providers. First of all, raw material suppliers carry out batch management when providing raw materials to food manufacturers, and input the original production data of raw materials, including manufacturing date, consumption period, country of origin, producer, whether or not to use drugs and other information into the two-dimensional code, print labels with the two-dimensional code, and paste them on the packaging box before handing them over to food manufacturers. When the raw materials of food manufacturers are put into storage, the data collector is used to read the two-dimensional code to obtain the original production data of raw materials, and the data is used to confirm whether the delivered products meet the purchasing standards of the manufacturers, and the raw materials that meet the purchasing standards are put into storage.

Food manufacturers make recipes according to the production plan of the day. According to the production plan, employees extract the necessary raw materials from the warehouse, weigh and subcontract all kinds of raw materials according to the requirements of each batch, and paste labels with two-dimensional codes on the subcontracted raw materials, which contain information such as raw material name, weight, input sequence and raw material number. According to the instructions of the production plan, a kanban with a two-dimensional code is printed and placed in front of the production line, and the two-dimensional code on the kanban is entered with job instructions. When mixing raw materials, read the code on the kanban and the two-dimensional code on each raw material to confirm whether the raw materials are put in correctly according to the production plan and record the information of using raw materials.

In each inspection process after the input of raw materials, the data collector is used to input the inspection data recorded manually in the past, and the data in the data collector is uploaded to the computer to generate the original production data, which makes it possible to trace the products and raw materials. Once the food is found to have problems, it can be effectively controlled and recalled according to the source to protect the legitimate rights and interests of consumers from the source.
