[Methods] By analyzing the invA gene of Salmonella, two pairs of efficient, rapid and specific amplification primers were designed and screened for the six conserved domains of the gene, and the LAMP detection kit for Salmonella based on this method was produced. [Results] The method is simple, sensitive, rapid and specific. The minimum detection concentration is 10~2-10~3 CFU/ml. [Conclusions] It can be used in the self-inspection of food production enterprises and the on-site sampling inspection and rapid detection of large quantities of samples by grassroots food safety inspection and supervision departments.展开更多
