摘要
目的 了解北京市社区居民冰箱使用习惯,为开展有针对性的食品安全健康教育提供依据。方法 采用多阶段分层随机抽样方法,选择北京市3个城区和2个郊区,每个区随机选择2~3个社区作为调查点,在选中的社区内随机抽取30户家庭作为本次研究对象。采用问卷调查了解居民家庭冰箱使用的卫生习惯,现场评估冰箱冷藏室内食物储存空间、实际温度以及是否存在异味,采用描述性统计方法对数据进行分析。结果 调查获得359户家庭的有效数据,有效率99.72%。水果、鸡蛋和熟食在冷藏室保存的做法正确的比例分别为75.21%、90.81%和93.59%。冰箱冷藏室清洗频率≥1次/月的家庭占57.10%,能够正确进行冰箱内部清洗的家庭占80.22%;现场评估发现冷藏室存放食物超过容积3/4的占80.22%,冰箱中存在异味的占10.86%,冷藏室温度>8℃的家庭占17.27%。不同地区、家庭人口数和家庭月收入分别在清洗冰箱的频次、食物摆放方式、食品储存空间和是否存在异味方面存在显著性差异(P<0.05)。结论 家庭冰箱冷藏室中食物保存习惯总体较好,但也存在生熟食物混放的情况,大多数居民家庭冰箱内存放食物过满,冷藏室温度高,应加强冰箱使用卫生知识的宣教,正确储存食品,预防食源性疾病的发生。
