# Design of Safety Evaluation and Risk Traceability System for Agricultural Product Quality
## 1 Introduction  
In recent years, the frequent occurrence of food safety problems in China has seriously jeopardized people's lives and health [1], and has also brought a huge economic burden [2]. Governments are highly concerned and have introduced a series of laws and regulations to ensure the quality and safety of agricultural products [3, 4]. Through the traceability of agricultural products, it realizes the tracking and tracing of product information in each link of the supply chain of agricultural products, strengthens the supervision and management of each link of agricultural products, and is of great significance for safeguarding the safety of people's lives and properties and maintaining the harmonious and stable development of the society. According to the relevant data statistics in the 2019-2021 China Food Safety Annual Report (as shown in Figure 1), although the number of food poisoning cases has shown a downward trend in the past three years, it still maintains a relatively high level. At present, the situation of food safety is still relatively severe [5], the number of patients and deaths caused by food poisoning remains high, and traditional traceability methods for agricultural products can no longer meet the demands of today's society for the quality and safety of agricultural products [6, 7]. Therefore, accelerating the construction of a traceability system for agricultural product quality and safety is of positive significance for improving the level of social public safety. In recent years, scholars at home and abroad have explored the application of information technology in agricultural quality and safety traceability systems from different angles. The research on traceability systems by scholars in China started in the early 21 st century and gradually developed into a relatively mature traceability system [8]. The design of traceability systems has also gradually shifted from single information data traceability to a system with evaluation functionality. [PERSON] et al. [9] elaborated on the challenges faced by Internet of Things technology in the traceability of the entire agricultural product industry chain. By reviewing the application of Internet of Things technology in the direction of agricultural product quality and safety monitoring, their value was affirmed, and the development significance of agricultural product quality and safety traceability systems was also demonstrated; [PERSON] et al. [10] faced the issue of identifying the effectiveness of information in the development of traceability systems. By establishing a unified language model and incorporating it into a system design, they achieved the identification and classification of dynamic participant groups in the vegetable supply chain traceability system that they had designed and developed. This provided a reference for establishing the model and incorporating it into the system's functional design; [PERSON] et al. [11] aimed to apply Internet of Things technology to supply chain management to improve the management level. By analyzing and dismantling the supply chain process, they designed and developed an agricultural supply chain management system based on RFID tag technology. They proposed a traceability model for visualizing the quality of agricultural products, providing a reference for achieving full traceability; [PERSON] et al. [12] designed a traceability system framework based on multi-agent and Internet of Things technology to better control the quality of agricultural products. They combined Agent technology with the agricultural product quality and safety traceability system, and the designed chain system improved the pertinence of controlling agricultural product quality. In response to mad cow disease, the European Union gradually established a traceability system starting in 1997, which was the earliest manifestation of a food traceability system [13].
