Objective To investigate the contamination of food-borne pathogens in fresh food in Putuo dis- trict of Shanghai, and to improve capabilities for controlling and early warning of food-borne disease. Methods Five kinds of food-borne pathogens were detected according to the Food microbiological examination （GB4789-2010） and the requirement of Project GFN. Results A total of 210 samples were collected from 5 sorts of fresh food in 2012, and the pathogens detection rates of contamination involved predominately were 71.43%, 64.29% and 61.90% in raw poultry, meat and beef. The pathogens detection rates of contamination were 46.43% and 21.43% in aquatic product and eggs. Five kinds of pathogens were found in 129 pieces of food samples （61.43%）. A total of 184 strains of food-borne pathogens were isolated, including 62 strains of Salmonella （29.52%）, 8 strains of Vibrio parahaemolyticu~ （3.81%）, 23 strains of Staphylococcus aureu~ （10.95%）, 71 strains ofListeria monocytogenes （33.81%）, 20 strains of Yer- sinia pseudotuberculosis （9.51%）.
