摘要： Background: With the increasing quantity and variety of food products, concerns regarding food quality and safety have attracted global attention. Numerous foodborne hazards potentially present at any stage of the food production process can enter the human body through the food chain. Even at trace levels, these hazards can cause a range of foodborne illnesses, posing significant risks to public health. Therefore, the development of accurate and rapid detection methods is crucial for the timely identification and management of contaminated food to ensure safety. Scope and approach: This review provides a comprehensive analysis of electrochemical sensor design strategies for detecting foodborne hazards. It covers sensor types, electrode materials, recognition elements, and the integration of smart technologies. The research progress on electrochemical detection of pesticides, antibiotics, mycotoxins, heavy metals and pathogenic bacteria in food matrices is systematically summarized. In particular, the electrochemical detection mechanisms for foodborne hazards and the application of smart sensing technologies are discussed in detail. In addition, the review discusses future prospects and current challenges in the application of electrochemical sensors in food analysis. Key findings and conclusions: Electrochemical sensors have been widely used for detecting foodborne hazards due to their high sensitivity, efficiency, rapid response, and practical applicability. Moreover, integrating electrochemical sensors with smartphones, microfluidics, or flexible materials enables point-of-care testing and on-site detection. Future research should focus on improving the robustness of portable electrochemical sensors and enhancing their resistance to interference in complex food matrices, thereby reinforcing food safety monitoring systems.
