【正文】 ocused on the processing of agricultural products and expanding the number and type of business . Therefore, this food supply chain is a prehensive, multispecies, multifrequency highvolume and mix of supply chain system. This food supply chain are more concerned about customer satisfaction, through the processing centers to respond quickly to market demand, and realtime on agricultural products and foodstuffs tailored and depth of processing, in order to achieve different from the lean agile logistics logistics strategy. Three. Food supply chain tracking and f ood quality and safety In recent years, the focus of the food supply chain collaboration to ensure delivery of quality from the gradual move to reinforce the quality and safety of food and agricultural products, such as BSE, foot and mouth disease and the emergence of geically modified foods. Agricultural products and food quality and safety of track without food supply chain management, so based on quality and safety of the food supply chain to track the food supply chain management has bee important and difficult. Golan. E by the United States and other fresh produce, meat products, w cereals and oilseed rape, and survey findings, three by the food supply chain tracking, food quality and safety in that there are great differences. The analysis of these differences, they also found that three agricultural products mon food supply chain management, that there are three driving forces. This is also the corporate implementation of the food supply chain management requires analysis examines the question: 1． will help differentiate the marketing of food and agricultural products to improve food and agricultural sales. Through those small or can not be directly found in food quality and safety features, can distinguish between different types of agricultural products and food. Because in the food and agricultural products on the market not only in large single grains and meat products, but also based on consumer preferences and tastes of different tailormade food. Some agricultural products and food quality may be easier to distinguish, while others are not easy to directly determine, even after the consumer can not immediately find its quality. For example, transgenic edible oil, if not identified, the consumer it is difficult to determine whether the oil processed from nongeically modified soybeans. Therefore, the quality of agricultural products and food safety and quality of the segmentation is a necessary prerequisite for differentiated marketing. conducive to quality and safety of agricultural products and food tracking, reducing the cost of food and agricultural products recall. Many panies have used the food supply chain tracking systems to minimize food safety system deficiencies may result in potential losses. Suppliers often have a strong economy driven, when discovered food safety hazards and quality problems are, they tend to take measures to avoid food quality and safety issues to the panies themselves, or have a negative impact on the brand. Based on the food supply chain tracking can help businesses identify and reduce the time to clean up the food in question, for many w foreign panies to reveal identifying information related to food packaging, to facilitate the identification of consumers and identified. For example, in the United States requested the recall of most food and agricultural products have been released in the United States Department of Agriculture Food Safety and Inspection Service39。 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。 Van Weele 根據(jù)市場對農(nóng)產(chǎn)品和食品信息的需求，確定食品供應(yīng)鏈信息跟蹤的寬度、深度和精度。 目前，歐盟已經(jīng)采用 EAN/UCC 系統(tǒng)，成功地開展了對牛肉、蔬菜等食品追蹤的研究。因此，對農(nóng)產(chǎn)品和食品的安全質(zhì)量和品質(zhì)進(jìn)行細(xì)分，是差別化營銷的必要前提。農(nóng)產(chǎn)品和食品質(zhì)量安全的跟蹤離不開食品供應(yīng)鏈管理，因此基于質(zhì)量安全的食品供應(yīng)鏈跟蹤成了食品供應(yīng)鏈管理的重點和難點。據(jù)有關(guān)統(tǒng)計表明，美國 2021 年度未加工和加工蔬
