Abstract
Water served as hand-washing-water by food vendors in Ilaro metropolis was assessed for presence of heavy metals and enteric bacteria. Twenty (20) water samples were collected from ten popular food vending sites in Ilaro town, and each site was sampled twice. The food vendors were classified into four categories based on the type of vending sites: roadsides, open air, closed/roofed and restaurants. The bacteriological analysis of the water samples was carried out using pour plate technique while assessment of the samples for heavy metals was by atomic absorption spectroscopy (AAS). The total viable count (TVC) and total coliform count ranged from 4. 0 x 105 - 2.2 x 107 cfu/ml and 2.4 x 102 - 4.0 x 103 cfu/ml. respectively. The Salmonella-Shigella count ranged from 0.2 x 102 - 1.0 x 102 cfu/ml. Presence of Lead (0.015 – 4.70 mg/l), and Cadmium (0.13 – 0.23 mg/l) was recorded in some of the water samples but there was no presence of Copper. Escherichia coli, Enterobacter sp. and Salmonella sp. were isolated from some of the water samples. The presence of these bacteria and heavy metals in the water samples is of public health concern. Therefore, the food vendors should be educated by the relevant agency of government, about the health implication of this to their customers and long term effect on their businesses.
