Recently, food safety concerns such as drug residues, food additives, food packing material, pesticide residues, foodborne pathogens, allergens, pesticide residues, foodborne pathogens, allergens, and heavy metal ions have caused threats to humans and the environment. Therefore, efficient and convenient chemical sensors are widely applied in testing these harmful and toxic ingredients. The performance of the sensors is mainly determined by the sensing materials. Transition metal phosphides (TMPs) have been recognized as promising and efficient sensing materials for building various high-performance sensor applications especially in the food industry due to their abundant reserves in the earth, tunable electronic structure, and distinctive physicochemical properties. Moreover, the properties, synthesis methods, and improvement strategies of TMPs electrocatalysts and their applications in chemical sensors for food safety detection, including electrochemical and optical (electrical) chemical sensors are summarized for the first time in this review. Finally, the potential directions of TMPs that may lead to significant breakthroughs in food safety detection methods are concluded and discussed. This review is significant for promoting the development of TMPs electrocatalysts and expanding the applications of TMPs-based chemical sensors in food safety. •The source of activity and properties of TMPs are introduced.•The synthetic and improvement strategies for TMPs are discussed.•The applications of TMPs in chemosensors for food safety detection are summarized.•The challenges and opportunities of TMPs in food safety sensors are proposed.
