目的：通过检测冰箱和冰柜内的大肠菌群，了解冰箱（柜）的卫生状况，预防食源性疾病的发生。方法：采用大肠菌群快速检验纸片法检测冰箱（柜）内的大肠菌群。结果：共检测冰箱7台，冰柜9台，大肠菌群阳性率为81.25%；生熟不分所占的比例为12.5%，杂物所占的比例为43.75%，污染物所占的比例为50%，异味所占的比例为12.5%；冰箱与冰柜大肠菌群阳性率之间比较差异无统计学意义；冷藏室与冷冻室大肠菌群阳性率之间比较差异无统计学意义。结论：冰箱冰柜的大肠菌群阳性率高，一般卫生状况较差。
Objective: To learn about hygienic situation of refrigerator （freezer）so as to prevent food-borne infection disease.Methods: Rapid coliform test paper method was adopted to detect the coliform group in refrigerator and freezer. Results: Among the total detection of 7 refrigerators and 9 freezers, coliform group positive rates were 81.25%. The proportion of the raw and cooked without distinction was 12.5%, debris 43.75%, pollutants 50%, smell 12.5%. The comparison between the refrigerator and freezer coliform bacteria positive had no significant difference （P>0.05）. Conclusion: The fridge and freezer are high in coliform group positive rate, poor in hygienic situation.
