Salmonella is a leading cause of foodborne disease worldwide and ready-to-eat (RTE) foods are regarded as a major source of infection and outbreak. In recent years, the consumption of Chinese RTE foods has raised markedly with the pace of life increasing. However, the prevalence of Salmonella in these foods in China and its potential risk to public health has not been well determined and evaluated...
In this study, we developed a rapid and sensitive loop-mediated isothermal amplification (LAMP) assay for Salmonella detection targeting the gene62181533. The addition of manganous ions and calcein to the reaction system allowed the visualization of an apparent color change during the amplification reaction. The detection limit of LAMP using a six-primer combination was 1.057 copies/μl (standard plasmid),...
