Objective:To determine the contamination situation of main food-borne pathogens in food,to identify high-risk foods,and to provide the basis for food-borne diseases prevention and control in Jiangsu province.Method: Salmonella,Listeria monocytogenes,Escherichia coli O157∶ H7,Campylobacter jejuni,and Vibrio parahaemolyticus were isolated and tested for biochemical characteristic,serotype according to national standard GB/T4789.Results: Total 764 and 1 071 food samples were detected in 8 monitoring sites respectively in 2008 and in 2009,including raw meat,raw poultry,cooked meat products,raw vegetables,aquatic products,and so on.The detection rates of Saimonella were 5.9% and 2.7% respectively;Listeria monocytogenes were 6.5% and 5.0% respectively;Vibrio parahaemolyticus were 15.9% and 7.8% respectively;Staphylococcus aureus were 5.6% and 5.0% respectively.Escherichia coli O157∶H7 was detected in 2009 and the detection rate was 0.3%;Enterobacter sakazakii was detected in 2008 and the detection rate was 5.0%.Campylobacter jejuni was not detected in both two years.There were 8 serological types to be separated by 70 plants of Saimonella,and most of them were Salmonella in fixed,Salmonella anatum,Salmonella derby and Salmonella typhimurium.Conclusion: Contamination by food-borne pathogens existed in food in Jiangsu province.Aquatic products and raw meat were main food suffered.Additionally,cooked meat and raw aquatic products could cause food-borne diseases with more possibility.
