Abstract：Objective To retrospectively analyze Salmonella strains isolated in Zigong City during 2007-2010, and to evaluate the value of molecular typing technique in identification and disposal of outbreaks of foodborne diseases. Methods Salmonella strains isolated from food and diarrhea patients in Zigong City during 2007-2010 were analyzed by pulsed field gel electrophoresis (PFGE), and BioNumerics software was used to analyze the genetic similarity index of the Salmonella strains. Results According to the PFGE patterns, 25 of the 55 Salmonella typhimurium strains isolated from stool samples of 10 diarrhea patients in 2007-2008 and 15 preserved eggs in 2008 were classified into type P9, and their genetic similarity was 100%. Conclusions Eggs contaminated by Salmonella typhimurium were the pollution sources that caused the outbreaks of diarrhea in 10 patients in Zigong City during 2007-2008. To quickly and accurately identify foodborne disease outbreaks and timely control and trace the outbreaks, PFGE and other molecular typing techniques should be widely used in food safety monitoring.
