Food safety detection is an important technical support for protecting public health and maintaining social stability. Owing to the strong affinity and specific recognition ability of aptamers, together with the high sensitivity, rapid response, and easy integration into miniaturized devices offered by electrochemical detection, electrochemical aptamer-based sensors (EAB) have shown promising potential for detecting food contaminants. This review systematically summarizes recent progress in this sensing technology for food safety analysis. It also outlines major aptamer immobilization strategies and discusses electrode materials employed for electrode surface modification. Particular attention is given to their applications in the detection of various contaminants in food safety. Based on current studies, the future development directions and application potential of this technology are also discussed.
