Background: Pathogens enter water via fecal contamination that can lead to severe and widespread human illness from drinking, swimming and bathing waters. However bottled water is supposed to be free from any microbial contamination. Aim: The present work evaluated the microbial level of six samples of bottled water collected from local market of Sri Ganganagar, Rajasthan. Materials and method: Six samples (Aquafina, Xalta, Bilseri, Kingfisher, Gallon , and Bailley) were analyzed for total viable count and coliform count. The serial dilution such as 10-2 was prepared for the study of microbial load. The pour plate method was employed for the estimation of microorganisms. The MPN method was employed for the detection of coliform. Results: The total viable count ranged from 1.0 x 102 to 16.78 x 102 TVC/ml. The average of three replicates were taken as recording. The coliform bacteria were not detected in any of the bottled water sample. It was however; found that total viable count of all bottled water samples was much higher than the IBWA standards. Conclusion: The microbial quality of bottled water samples were not appropriate as per IBWA as samples showed higher bacterial count which can further effect the health of the consumer.
Key Words: Bottled water, MPN method, Coliform
