How to establish pesticide traceability system in vegetable base.

With the improvement of people's living standards, the vegetable traceability system requires higher food safety and quality. Enterprises use anti-counterfeiting traceability system to trace the whole process of products and improve the tracking supervision of vegetables. Thus, a series of full traceability from vegetable planting to consumers' mouth is realized. The process of fertilization and quality inspection of vegetables should be tracked and recorded in the system. This means that in the future, when consumers buy food in market, supermarket and other terminal stores, they only need to scan the traceability code on vegetables to know where the source of purchase is and which wholesale markets they pass through ... All the upstream links can be seen at a glance.

first, how to do the vegetable traceability system

The vegetable traceability system is a system that uses the Internet of Things technology to establish a standardized vegetable market covering large wholesale markets and supermarket chains. In the future, the data of vegetable production, transportation and sales in Xi 'an urban area will be entered into the network platform, so that the source of products can be traced, the destination can be verified and the responsibility can be investigated, and consumers can know the commodity information in real time by virtue of the "traceability code" on the sales receipt.

For example, in terms of food and agricultural products, if you want to trace a watermelon, and this watermelon can be traced back, you can directly find out who planted the watermelon, when to raise seedlings, when to apply fertilizers and drugs, what fertilizers were applied and who operated them, and so on from the QR code on the watermelon, so you can rest assured that you can enjoy this watermelon. If you don't trace back, you will know nothing about the safety information of this watermelon.

second, the application of vegetable traceability system

it is reported that the "circulation link traceability system" developed by Lixin Chuangyuan for this vegetable wholesaler, with a traceability code certificate, can check the source, channel and other links.

among them, the circulation link of vegetables is: supplier (vegetable concentration place)–> Wholesalers–> Distribution Center/Farmers Market–> Terminal store–> Consumers. The functional attributes of each link are as follows:

Supplier: cooperative vegetable farmers, purchasing all kinds of vegetables for wholesalers to purchase.

Wholesalers:

① Buy vegetables in bulk and conduct inspection and quarantine;

② Assign codes (large codes) to vegetables, and collect and record traceability information, including: from whom, what, how much, to whom, and inspection results;

③ distribute the vegetables with large size to the market;

distribution center/farmer's market: ① split packaging; (2) code vegetables (medium code); ③ Distribute and sell to terminal stores.

terminal store (supermarket): ① split packaging; (2) coding vegetables (small size); ③ Retail sales to consumers.

consumer: scan the two-dimensional code of vegetables to inquire about the detailed information of the circulation link, including the source of vegetables, circulation channels, handlers and vegetable inspection reports.

Vegetable entry management: set up a registration window at the entrance of vegetables, and the wholesale market administrator will verify (certificate of origin or inspection certificate) the receipt. After the goods and certificates meet the requirements, divide the batches, input the information into the traceability subsystem, generate an electronic ledger, and save the original documents for more than 2 years. If there is no certificate of origin or test certificate, the owner (wholesaler) should fill in the information of vegetable origin, variety and quantity by himself, and sign it for confirmation, which will be recorded by the wholesale market administrator. For those who have established an electronic ledger, the wholesale market manager verifies the receipt (transaction voucher), reads the meat and vegetable circulation service card, and automatically imports the information into the traceability subsystem to complete the matching verification with the information of this batch of vegetables in the system.

batch management of vegetables: take the certificate of origin or certificate of inspection as the basis for batch management, and vegetables with the same certificate of origin or certificate of inspection are the same batch. Different batches of vegetables should be kept separately, and each batch should be distinguished.

registration of detection information: after the registration of vegetables, the wholesale market carries out pesticide residue detection according to batches and varieties, and records the detection results (qualified or unqualified) into the traceability subsystem.

vegetable transaction management: the wholesale market should build an electronic settlement system, support multiple payment methods, and undertake the functions of fund settlement and traceability management. Set up a special registration window for vegetable trading, or use a mobile registration terminal, a self-service trading terminal or a hand-held trading terminal to enter the transaction information, associate the vegetable source information with the flow direction information, transmit it to the settlement system in real time, realize the connection between the capital flow and the information flow, and write the relevant information into the buyer's meat and vegetable circulation service card to print the transaction voucher.
