Research progress in rapid detection of typical pathogenic bacteria in food stuff

Food contamination of pathogenic bacteria poses a serious threat to human health. Accurate and rapid detections of pathogenic bacteria in food stuff are of great concerns， which are necessary to reduce outbreaks of foodborne diseases. Although traditional culture­based detection of pathogen are reliable and classical， they suffer from cumbersome and time­consuming. Recently， various detection strategies based on electrochemistry and optical spectroscopy using advanced nanomaterials and micro­analytical systems have emerged as portable and ultrasensitive sensing platform. This review focuses on several typical rapid detection method for foodborne pathogens， and emphasizes the negative effect of interference to these detection systems. Some sample processing method for achieving accurate detection are listed. Finally， taking typical food­borne pathogens as examples， the development status and future research directions of rapid detection technology are briefly described.
