【正文】 agricultural products in large supermarkets (such as 711, Royal Ahe, Carrefour, Sainsburry and TESCO) sold of. These large supermarkets in order to meet the market for agricultural products, quality consistency and supply stability requirements, the supplier of a rigorous screening. Therefore, the implementation of the Royal Ahe supermarket fresh food supply chain management, will be vendors from the original 250 was reduced to about 60, so that the logistics system more efficient and concise. With the upper reaches of the sharp drop in the number of suppliers of agricultural products and the continuous expansion of the supermarket chain, this food supply chain, upstream suppliers and downstream number of supermarket chains showed symmetrical growth trend. Logistics development in developed and more mature cities, this has been expressed in the food supply chain, centralized purchasing, reduce nonuniform flow distribution and valueadded logistics sectors, in order to achieve cost savings of lean logistics strategy. 4． mixed food supply chain. With consumer demand for food and agricultural products market diversification, the proportion of food and agricultural processing has gradually improved. According to the statistics that the United States in 2021 raw and processed vegetables for 15% and 85%。 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 people’s increasing demands for food consumption, the inevitable result. Specifically, the causes are: (1) the consumer fresh food and agricultural products have bee increasingly demanding and require delivery of food and agricultural products, the production period as short as possible. (2) consumers of food and agricultural products quality requirements have bee more sophisticated, forcing food manufacturers to implement the food supply chain management to ensure a stable supply of raw materials upstream and downstream sales channels. (3) food quality and safety of consumers are increasingly concerned about. In order to meet consumer demand for food and agricultural products in the type and quantity requirements, panies continue to seek and develop new technologies, and new technologies and new methods of excessive use (such as pesticides, hormones, antibiotics and geically modified technology, etc.) to meet the consumer demand, but also inevitably produced a hazard causing human food quality and safety issues. This is because buyers and sellers in the market information asymmetry, consumers in the purchase of food or agricultural products, the products do not understand the health, environmental and safety information. Therefore, enterprises need in all aspects of the production process inspection and testing of products and timely disclosure of information to consumers. (4) food and agricultural panies forced the government, Relevant social w anizations and consumer demands and pressure to press the food supply chain to operate. For example, EU regulations No. 178, as from 2021 in all EUwide sales of food, must be implemented to track and trace food supply chain。只有當收益大于成本時，企業(yè)所選擇的寬度、深度和精度才是實施供應(yīng)鏈質(zhì)量安全跟蹤 的動力和保證。 然而，對所有食品和農(nóng)產(chǎn)品都實施食品供應(yīng)鏈的質(zhì)量安全跟蹤是沒有必要的。 。因此某種產(chǎn)品一旦出現(xiàn)問題，這些標識信息將能夠發(fā)揮很大的作用。供應(yīng)商通常有著很強的經(jīng)濟驅(qū)動性，當發(fā)現(xiàn)食品有安全隱患和質(zhì)量問題時，他們 往往會采取措施，避免食品質(zhì)量安全問題給企業(yè)自身或品牌帶來負面的影響。例如，轉(zhuǎn)基因食用油，如未進行標識，消費者就很難判別食用油是否由非轉(zhuǎn)基因大豆加工而成。這也是企業(yè)實施食品供應(yīng)鏈管理時需要分析考察的問題： ，以提高食品和農(nóng)產(chǎn)品的銷量。 三．食品供應(yīng)鏈跟蹤與食品質(zhì)量安全 近年來，由于食品
