Objective:To detect the enteric pathogens in food-service staff in Yantai city,and provide the basis for food safety risk assessment.Methods: 25600 food-service staff in Yantai were recruited to detect their enteric pathogens from 2009 to 2011.According to Food hygiene inspection methods(microbiology section),Salmonella,Shigella,Diarrheagenic E.coli,Vibrio parahaemolyticus,Vibrio alginolyticus,Non-O1 Vibrio cholerae,Aeromonas caviae,Aeromonas,Vibrio hollisae were detected respectively.Results: 1.The biochemical spectrum coincidence rate was 93.8%~99.9% according to the biochemical identification results.2.254 strains of intestinal bacteria were detected,and the positive rate was 0.99%,144 strains of the intestinal bacteria were Vibrionaceae bacteria,and the positive rate was 56.69%.In 144 strains of Vibrionaceae bacteria,117 strains were Vibrio parahaemolyticus,6 strains were Aeromonas sobria,2 strains were Aeromonas caviae,1 strain was Aeromonas bacteria,5 strains were Non-O1 Vibrio cholerae,12 strains were Vibrio alginolyticus,and 1 strain was Vibrio hollisae.110 pathogenic strains of intestinal bacilli were detected,accounting for 43.30% of the positive bacteria.In 110 strains of enteric bacilli bacteria,76 strains were Salmonella,6 strains were Shigella,9 strains were pathogenic E.coli,14 strains were invasive E.coli,5 strains were enterotoxigenic Escherichia coli.The positive rate of intestinal pathogens showed downtrend year after year with significant difference.3.The high positive rates of intestinal pathogen were found in Vibrio parahaemolyticus(46.06%) and Salmonella(29.90%) were the highest.Conclusion: The main pathogenic bacteria carried by food services staff was intestinal Vibrio pathogens.The investigations on pathogenic bacteria in this population could help to find out the critical control point of foodborne illness caused by microbes,and take targeted measures to regulate the related personnel health examination,as well as to ensure the food hygiene and safety.
