Bacterial contaminants of Vhuswa--a traditional maize-based weaning food, and domestic drinking-water stored in impoverished rural households in Venda of Limpopo province, South Africa, were determined. One hundred and twenty-five samples of Vhuswa fed to children aged less than five years were assessed for Escherichia coli, Campylobacter jejuni, Salmonella, and Shigella. The microbiological quality of 125 drinking-water samples was also evaluated using total coliforms, faecal coliforms, and faecal streptococci as indicators. The frequency of isolation of E. coli, Salmonella, Shigella, and C. jejuni from the Vhuswa samples was 70%, 5%, 5%, and 2% respectively. The geometric mean counts of total coliforms, faecal coliforms, and faecal streptococci in tap-water stored in household containers ranged from 4.9x10(2) to 5.8x10(3) cfu 100 mL(-1), 2.6x10(2) to 3.7x10(3) cfu 100 mL(-1), and 3.1x10(3) to 5.8x10(3) cfu 100 mL(-1) respectively, and for stored spring water it was 5.1x10(3) cfu 100 mL(-1), 3.2x10(3) cfu 100 mL(-1), and 5.1x10(3) cfu 100 mL(-1) respectively. The frequent contamination of water and food samples in this study has important implications for the health of children from impoverished communities.
对南非林波波省文达地区贫困农村家庭储存的传统玉米断奶食品Vhuswa以及生活饮用水中的细菌污染物进行了测定。对125份喂食五岁以下儿童的Vhuswa样本进行了大肠杆菌、空肠弯曲菌、沙门氏菌和志贺氏菌的检测。还以总大肠菌群、粪大肠菌群和粪链球菌为指标评估了125份饮用水样本的微生物质量。Vhuswa样本中大肠杆菌、沙门氏菌、志贺氏菌和空肠弯曲菌的分离频率分别为70%、5%、5%和2%。家庭容器中储存的自来水总大肠菌群、粪大肠菌群和粪链球菌的几何平均计数分别为4.9×10²至5.8×10³ cfu 100 mL⁻¹、2.6×10²至3.7×10³ cfu 100 mL⁻¹和3.1×10³至5.8×10³ cfu 100 mL⁻¹，储存的泉水分别为5.1×10³ cfu 100 mL⁻¹、3.2×10³ cfu 100 mL⁻¹和5.1×10³ cfu 100 mL⁻¹。本研究中水样和食品样本的频繁污染对贫困社区儿童的健康具有重要影响。
