Abstract
Twenty brands of sachet water sold within Ilorin metropolis were assessed for their Physicochemical and bacteriological quality using standard methods. The pH, chloride content, and total hardness of the sachet water samples ranged from 6.5 – 8.0, 0.78 – 5.04 mg/l, and 15 – 75mg/l respectively. The counts of heterotrophic bacteria, total coliform, and faecal coliform ranged from 0 to 2.8 x 103 cfu/ml,0 to 52 MPN/100ml, and 0 to 24 cfu/ml respectively. Pathogenic bacteria such as Staphylococcus aureus E. coli, and Salmonella sp. were isolated while Shigella sp. and Pseudomonas aeruginosa were not isolated in any of the samples. Furthermore, Staphylococcus equorum, Staphylococcus hominis, Bacillus stearothermophilus, Bacillus psychrosaccharolyticus, Corynebacterium pseudotuberculosis, Micrococcus kristinae, Micrococcus luteus, Micrococcus candidus, Micrococcus flavus, Bacillus smithii, and Staphylococcus capitis were also characterized and identified. It can be concluded from this study that most of the sachet water purchased from the open markets were not wholesome. Only six brands of the sachet water samples met the bacteriological quality with regard to heterotrophic bacteria, total coliform, and faecal coliform counts. It is recommended that producers of sachet water should adhere to good manufacturing practices and there is need for proper handling of these products during sales and distribution.
