A study was carried out to identify the microbial contaminants of weaning foods in an Egyptian village and the sources of contamination. All 300 households containing infants (< 24 months) were visited. Information regarding food preparation and household sanitation was gathered. Samples of weaning foods (270) were collected and analysed for the presence of Escherichia coli, Bacillus cereus, Shigella and parasites. The first two pathogens were detected in 43.7 per cent and 21.4 per cent of samples respectively. The others were not detected in any sample. The risk of contamination by E. coli and B. cereus was significantly associated with the presence of dung and/or refuse in the house, lack of indoor latrine, non-use of latrine by children, weaning foods not freshly prepared, uncovered storage of foods, and the presence of a case of diarrhoea in the house.
开展了一项研究，以确定埃及一个村庄断奶食品的微生物污染物及其污染源。走访了所有300户有婴儿（<24个月）的家庭。收集了有关食物制备和家庭卫生设施的信息。采集了270份断奶食品样本，分析其中大肠杆菌、蜡样芽孢杆菌、志贺氏菌和寄生虫的存在情况。前两种病原体分别在43.7%和21.4%的样本中被检测到。其他病原体在任何样本中均未被检测到。大肠杆菌和蜡样芽孢杆菌污染的风险与房屋内粪便和/或垃圾的存在、缺乏室内厕所、儿童不使用厕所、断奶食品不是新鲜制备、食物未加盖储存以及房屋内有腹泻病例显著相关。
