目的本研究旨在衡量卫生干预对孟加拉国断奶食品污染的影响。方法选取60户家庭：30户研究家庭和30户对照家庭。在基线时，从所有60户家庭收集断奶食物样本，并按照标准程序检查粪便大肠菌群（FC）、粪便链球菌（FS）和产气荚膜梭菌（CP）。烹饪后，在喂食前三次采集食物样本。根据危害分析关键控制点（HACCP）程序，确定了关键控制点。然后对30个研究家庭中的母亲进行了为期4周的如何达到控制点条件的培训。然后，再次收集和分析食物样本。结果在基线时，来自研究和对照家庭的断奶食品被FC和FS严重污染。第一次饲喂时，试验组的FC和FS分别为1.84log10和1.92log10菌落形成单位(cfu)/g，对照组的FC和FS分别为0.86log10和1.33log10cfu/g。干预后，研究家庭的FC和FS计数分别下降到0.10log10和0.09log10cfu/g，差异有统计学意义(P
Objective This study was conducted to measure the impact of a hygiene intervention on the contamination of weaning food in Bangladesh. Methods Sixty households were selected: 30 study and 30 control households. Samples of weaning food were collected from all the 60 households at baseline and examined for faecal coliforms (FC), faecal streptococci (FS) and Clostridium perfringens (CP) following standard procedures. After cooking, food samples were collected on three occasions before feeding. Following Hazard Analysis Critical Control Point (HACCP) procedures, critical control points were determined. The mothers in the 30 study households were then trained for 4weeks in how to attain the control point conditions. Then, again the food samples were collected and analysed. Results At baseline, weaning foods from study and control households were heavily contaminated with FC and FS. The FC and FS counts were 1.84log10 and 1.92log10 colony-forming unit (cfu)/g, respectively, in the study households, and 0.86log10 and 1.33log10cfu/g, respectively, in the control households in the first feeding. After the intervention, the FC and FS counts in study households had dropped to 0.10log10 and 0.09log10cfu/g, respectively, a statistically significant reduction (P
