Different foods were detected. There was no significant difference in different seasons. The province’s 14 municipalities, the detection rate of 3.11% ~ 13.44%. Conclusions The contamination of Staphylococcus aureus in instant food in Gansu province is serious. The detection rates of Wuwei, Baiyin and Longnan are higher in fourteen prefectures and cities.
