【正文】 ricultural products have been released in the United States Department of Agriculture Food Safety and Inspection Service39。s agriculture industry in less developed regions, due to lack of upstream farmers to connect one end, other end of the link sales market, specializing in the processing of agricultural products among leading enterprises and the corresponding part of agricultural production often out of line with market demand. Therefore, Tmiddle part of the food supply chain as a low level of absence and logistics operation, prone to upstream farmers and downstream production of agricultural products sold blindly difficult phenomenon. 3． symmetric food supply chain. With the emergence of new sales formats, distribution channels are increasingly largescale professional market w and supermarket monopoly, the traditional sales of agricultural products and food forms have been replaced by supermarkets, and this trend is more and more obvious, and because of its technological level of agricultural products production also tends to intensive management by a few growers. Ahe by the Royal Thai supermarket fresh food supply chain management survey found that 50% of Bangkok39。 the same in the United States Food and Drug Administration regulations in the United States and abroad engaged in food production, processing and packaging departments and related anizations in the December 12, 2021 to register the Food and Drug Administration for food safety tracking and tracing, on the allowed unregistered persons engaged in food production and sales. Thus, the food supply chain management is inherent in the market dynamics and the external pressure the government to promote the case. Two. Food supply chain, production logistics system The formation of the food supply chain logistics system with the changing content of closely related, particularly in the food and agricultural production logistics system evolving situation, for people to create a highly efficient food supply chain management paradigm provides the basis. According to food and agricultural products logistics stage of development, typical of the food supply chain can be divided into dumbbellshaped, T, symmetric and mixed four types. 1． dumbbell food supply chain. This type of food supply chain is a quasistrict supply chain. It is characterized by a shorter supply chain, connecting the main lot located at both ends of the transaction, while the middle of the main chain are few and fewer transactions, showing the dumbbell type. Upstream producers have poor technical conditions, production is low and less variety, it gathered a large number of upstream agricultural producers。 the third stage of supply chain integration management phase, the study extends further upstream to the most upstream agricultural enterprises (such as seed suppliers, etc.), the purpose is to extend the tracking and tracing of food quality and safety of w agricultural products issues in order to quickly and effectively identify and solve problems. This article describes the production of different food supply chain logistics system characteristics, and the food supply chain management with the development of food quality and safety are analyzed and discussed. One. Food causes of supply chain management In recent years, the food supply chain, production and development of people39。s management, food and agricultural industries have followed suit and Supply chain management with a tool to improve their petitiveness. 1996, Zuurbier and other scholars in general, on the basis of the supply chain, first proposed the concept of the food supply chain, and that the food supply chain management of agricultural and food production and marketing anization, food and agricultural products in order to reduce logistics costs and improve its quality and safety and logistics service level and for vertical integration mode of operation. Now, in the ., UK, Canada and the Netherlands and other more developed countries, agricultural production, this management model has been widely used, and gradually bee the focus of academic research project. The food supply chain management research has gone through three stages: the first stage of the business flow management phase, the study of agricultural products and food processing enterprises, including the output of consumer spending to business before the flow phase, the content of their research is often included I
