Sanitation facility conditions and waste disposal practices are hypothesized to affect the fecal contamination of drinking water and kitchenware. The present study aimed to examine the physical conditions of sanitation facilities and waste disposal locations as well as determine the concentrations of Escherichia coli in drinking water, cups, dishes, flies, toilet floors, and kitchen floors. A total of 336 samples were collected from 17 households in peri-urban Lusaka. Generalized linear mixed models showed that six out of seven physical pit-latrine conditions, waste disposal practices, and kitchen hygiene practices had significant effects on the contamination of either kitchenware or drinking water. The results highlighted that improving the physical pit-latrine conditions, dumpsite location, washing water, and kitchenware-drying location may potentially reduce fecal contamination of drinking water, cups, and dishes.

假设卫生设施条件和废物处理做法会影响饮用水和厨具的粪便污染。本研究旨在检查卫生设施和废物处理地点的物理条件，并确定大肠杆菌的浓度饮用水、杯子、盘子、苍蝇、厕所地板和厨房地板。从卢萨卡城郊的 17 个家庭共收集了 336 个样本。广义线性混合模型表明，七分之六的物理坑式厕所条件、废物处理做法和厨房卫生习惯对厨具或饮用水的污染有显着影响。结果强调，改善物理坑式厕所条件、垃圾场位置、洗涤水和厨具干燥位置可能会减少饮用水、杯子和盘子的粪便污染。
