On the Microorganism's Test of Food-wrapping Paper in Dali

Objective: To learn about the hygienic situation of wrapping-paper for cooked food in Dali so as to provide basis for public hygiene supervision. Methods: Randomly gather food wrapping paper of different materials from school canteens, food markets,and supermarkets. Test their bacterial content by culturing the specimens, observing colonial morphology and Gram's stain. Results:There were 155 specimens carrying bacteria among 200 specimens. Total detected rate was 77.5%. The detected rates of three different areas were 65.7%（school canteen）, 82.9%（food market）and 85.0%（supermarket）. The detected rates of three different materials were 68.2%（ordinary white paper）, 91.9%（Kraft paper）and 70.0%（oil-proof paper）. Conclusion: Contamination ratio of wrapping paper for cooked food was higher in Dali Area.
