The microbiological quality of bottled mineral water marketed in Ludhiana was examined, Twenty three brands were analyzed for presumptive coliform count by multiple tube tests, and E. coli count was confirmed by Eijkman test. Bacterial and fungal loads were tested by membrane filtration test. Out of 23 only one sample (4.4%) showed the presumptive coliform count to be 460 most probable number (MPN)1 1 00ml,and 1 was found to be positive when tested by Eijkman test for Ecoli. In the membrane filtration test three samples (13%) showed more than two types of bacteria. Different types of bacteria isolated included Bacillus sp (19/23). Pseudomonas spp (13123), Ecoli, Klebsiella sp and S.albus one each Fungi was isolated from five of twenty three.(22%) samples. Only one brand of mineral water was unfit for human consumption.
