Objective To verify the technical level of Salmonella detection of Tarim University in food safety risk monitoring project of China. Methods The experimental samples were processed in accordance with the requirements of operation instruction. The proficiency testing of isolation and identification of Salmonella were conducted according to the GB 4789.4-2016 National food safety standard-Food microbiological examinationSalmonella. Serological identification and serotyping of samples that accorded with Salmonella positive characteristics were performed. Results Sample 1 was detected Salmonella Stanley, sample 2 was detected Salmonella Kentucky, and sample 3 was not detected any Salmonella. The results of the three samples were satisfactory, which were consistent with the results of the organizers. Conclusion Through this proficiency verification, the microbiological examination ability and Salmonella detection technology level of the test center have been effectively verified and improved. It should improve the testing ability and reliability of our laboratory.
