Abstract: Salmonella Typhimurium, as a significant foodborne pathogen, poses a continuous threat to public health and safety. The development of rapid and accurate detection technologies is crucial for the effective prevention and control of this pathogen. Immunological detection methods, with their high sensitivity and strong specificity, have become a research hotspot in this field. This article reviews the major immunological techniques applied to the detection of Salmonella Typhimurium, including both conventional and novel detection technologies. By elaborating on the principles, performance characteristics, advantages, and limitations of various methods, this paper aims to provide a theoretical basis for the development of a more efficient and user-friendly detection system, thereby strengthening the food safety monitoring chain and improving response to public health risks.
