The microbiological status of water from dispensers in different roadside restaurants of Dhaka city and Savar area was analyzed in this study. Seven samples from Dhaka and 8 samples of Savar were checked. The heterotrophic plate count was in a range of 1.0x103 CFU mL-1 to 2.0x104 CFU mL-1 (from new bottles), 1.0x103 to 1.5x104 CFU mL-1 (after dispensation), and 1.5x103 CFU mL-1 to 1.0x105 CFU mL-1 (from serving glass). In several of the samples, the heterotrophic plate count was higher than the count in water from new bottle or after dispensation, suggesting added contamination from the serving glass. 80% of the samples were contaminated with total and fecal coliform bacteria, which render these waters unacceptable for human consumption. The samples were found to contain gram negative bacteria like E. coli, Shigella sp., Klebsiella sp., Enterobacter sp., Pseudomonas sp., and Salmonella sp., which are potential pathogens and thus pose a serious threat to public health. This study elucidates the importance of monitoring the bottling companies and the restaurants and put them under strict regulations to prevent future outbreak of any water borne diseases caused by consumption of dispensed water.
