Methods According to the requirements of the work manual of calendar year national surveillance, collect food samples in different season and different place, and detect them by the specified method. Results A total of 538 strains of Staphylococcus aureus were detected in 1284 foodstuffs in 18 categories. The overall detection rate was 4. 13％. Among them, the highest detection rate is fresh fruit and vegetable juice, which is 21. 28％; followed by cold noodles rice products, raw meat and raw meat products, the detection rates were 13. 51％ and 12. 50％ respectively. The detection rate of Staphylococcus aureus in bulk food (6. 49％) was higher than that of pre-packaged food (0. 92％), the difference was statistically significant (χ2= 24. 556, P ＜ 0. 01). There was no significant difference in the detection rate of Staphylococcus aureus among the four quarters (χ2= 4. 274, P＞ 0. 05). Conclusion The Staphylococcus aureus has been detected in many kinds of food and the contamination is serious and widely, so there is some of potential safety hazard and some measures must be taken to ensure the food security for citizens.
