Results A total of 50 strains of pathogens were detected from 180 food samples, the overall detection rate was 27.78%. In four major categories of food, raw aquatic animal products had the highest contamination rate, the detection rate was 52.00%, followed by cooked meat products（24.29% ）, cooked rice and flour products （ 17.50% ）. In eight kinds of pathogens, the detection rate of Vibrio para- haemolyticas was highest, accounting for 52.00%, followed by Staphylococcus aureus （ 14.55% ）, Bacillus cereus （7.50%）, Listeria monocytogenes（ 4. 55% ）.
