Abstract: Salmonella is one of the most common foodborne pathogens, and the traditional methods for Salmonella detection include biochemical identification following isolation and culture, immunoassay, and nucleic acid analysis, which, despite having high reliability, have low detection limits and are tedious and time-consuming. The biosensor is a new technology for rapid detection of Salmonella integrating biology, chemistry, optics and other technologies. This review presents a comparison of the traditional methods for Salmonella detection, and it focuses on describing the optical and electrochemical biosensors based on nanomaterials and aptamers. Finally, we conclude with an outlook on the future development of biosensors for Salmonella detection.

Key words: Salmonella; biosensor; detection technology
