Supply chain refers to a behavior system composed of interrelated logistics and information flow that cross organizational boundaries. Food supply chain is a food production and supply network system composed of agriculture, food processing industry, logistics and distribution industry and other related enterprises. Generally speaking, the food supply chain consists of different links and organizational carriers: the supply link of pre-natal seeds, feed, fertilizers, pesticides and other means of production (suppliers of farmers), the production link of aquaculture in production (farmers), food processing enterprises, and food is packaged, stored and distributed to retailers or restaurants through distribution enterprises, and finally reaches consumers.

The concept of integrated management of food supply chain originated in Europe. It regards the supply chain as a whole and implements comprehensive planning, cooperation and commodity flow control. Its core content is quality certification and tracking management. Different from the general supply chain management, the comprehensive management of food supply chain must take safety as the primary goal. To ensure the food safety of the whole society, it is necessary to strengthen the safety management of all links in the food supply chain, that is to say, food safety has become the public responsibility of every participant in the food supply chain. The idea of integrated supply chain management provides a basic idea for solving the safety problems in food supply chain.
