Food and drug safety traceability system is a system that relies on modern information technology to give early warning to possible hidden dangers of food and drug safety  The reason why it is widely adopted by some countries is that on the one hand, it can reduce the cost of information acquisition and improve the efficiency of supervision  On the other hand, it can force enterprises to improve safety awareness and take the initiative to control risks  This system has been introduced in China for many years and is reflected in relevant laws and regulations as well as action plans
However, in practice, problems such as regional segmentation and division of departments are still quite prominent, and there is no efficient local linkage and joint force of departments, which lacks overall effect on solving food and drug safety problems
China's food and drug safety traceability system still needs to be improved
