Abstract: In this study, Staphylococcus aureus was isolated and identified from 505 food samples (including raw milk, raw meat, fruits, vegetables, aquatic products, frozen foods and soybean products) collected in Shanghai according to GB4789.10—2010. In addition, PCR was performed for further confirmation. Staphylococcus aureus was detected in 117 food samples, with a total detection rate of 23.2%. The highest detection rate (32.9%) of Staphylococcus aureus in raw meat was found followed by frozen foods (26.7%) and raw milk (26.3%). In addition, the detection rates of Staphylococcus aureus in fruits and vegetables, aquatic products and soy products were lower than 16%. These results revealed the basic distribution status of Staphylococcus aureus in some types of foods in Shanghai, which may provide clues for monitoring Staphylococcus aureus in food processing, controlling food poisoning and tracing pollution sources.
