According to the notice of the State Administration for Market Regulation, pesticide residues have become the primary factor affecting food safety, and how to strengthen the detection of pesticide residues in food has become the focus of social attention. Cyromazine is the pesticide with the highest number of reported pesticide residues exceeding the standard. The abuse of cyromazine poses a serious threat to food safety and human health. This review provides an overview of the current methods and technologies applied to detecting the cyromazine in food, including high-performance liquid chromatography, liquid chromatography-mass spectrometry, immunosensing technology, chemical sensor technology and aptamer-based sensor technology, in order to provide research ideas for improving the detection efficiency of cyromazine.
