The food and drug safety traceability system is a system that relies on modern information technology to warn of potential food and drug safety hazards. The reason why it is widely adopted by some countries is that on the one hand, it can reduce the cost of information acquisition by the regulatory authorities and improve the efficiency of supervision; on the other hand, it can also force companies to increase their safety awareness and actively carry out risk control. This system has been introduced to China for many years and is reflected in relevant laws and regulations and action plans. However, in practice, the problems of regional division and division of government are still outstanding, and there is no efficient local linkage and joint efforts of departments, which lacks the overall effect on solving food and drug safety problems.
