    Microbiological quality of water processed and bottled in Zimbabwe

    No full text
    A total of sixty samples of bottled water processed in Zimbabwe by three companies, were analysed microbiologically, to assess the relative safety of locally processed bottled water. The samples were from different batches and from different storage conditions and the analyses were for total viable counts and coliforms. Four (6.7%) and seven (11.7%) samples were found to exceed the recommended maximum total viable and coliform counts, respectively. There was a low incidence of Staphylococus aureus (3.3%), Pseudomonas species (6.7%) and Bacillus species (5%). Overall, the work shows that locally bottled water is generally safe, microbiologically, though it is necessary to continue with precautionary measures because any lapse in hygiene may lead to microbial proliferation.

    <div><p>Background</p><p>Packaged water products provide an increasingly important source of water for consumption. However, recent studies raise concerns over their safety.</p><p>Objectives</p><p>To assess the microbial safety of packaged water, examine differences between regions, country incomes, packaged water types, and compare packaged water with other water sources.</p><p>Methods</p><p>We performed a systematic review and meta-analysis. Articles published in English, French, Portuguese, Spanish and Turkish, with no date restrictions were identified from online databases and two previous reviews. Studies published before April 2014 that assessed packaged water for the presence of <i>Escherichia coli</i>, thermotolerant or total coliforms were included provided they tested at least ten samples or brands.</p><p>Results</p><p>A total of 170 studies were included in the review. The majority of studies did not detect fecal indicator bacteria in packaged water (78/141). Compared to packaged water from upper-middle and high-income countries, packaged water from low and lower-middle-income countries was 4.6 (95% CI: 2.6–8.1) and 13.6 (95% CI: 6.9–26.7) times more likely to contain fecal indicator bacteria and total coliforms, respectively. Compared to all other packaged water types, water from small bottles was less likely to be contaminated with fecal indicator bacteria (OR = 0.32, 95%CI: 0.17–0.58) and total coliforms (OR = 0.10, 95%CI: 0.05, 0.22). Packaged water was less likely to contain fecal indicator bacteria (OR = 0.35, 95%CI: 0.20, 0.62) compared to other water sources used for consumption.</p><p>Conclusions</p><p>Policymakers and regulators should recognize the potential benefits of packaged water in providing safer water for consumption at and away from home, especially for those who are otherwise unlikely to gain access to a reliable, safe water supply in the near future. To improve the quality of packaged water products they should be integrated into regulatory and monitoring frameworks.</p></div
