[ Results ] A total of 23 strains of pathogens were detected from 291 specimens of 6 kinds of food,the total positive rate was 7.9%. Seven strains of Vibrio parahaemolytieus were detected and the positive rate was 8.8% ; 11 strains of Staphylococcus aureus were detected with the positive rate of 5.2% ;5 strains of Monoeyte hyperplasia Lester bacteria were detected wiht the positive rate of 2.4% ;Salmonella, Escheriehia eoli O157： H7, Vibrio vulnificus, Enterobaeter sakazakii and Shigella sonnei were not detected.
