Bottled water is generally accepted as safe for consumption. However, its potability is uncertain. Ninety samples of Six national and 3 local brands marketed in Mangalore City were studied. Seven of these were ISI certified. Bacteriological analysis of these samples were carried out for viable count, presumtive coliform count by multiple tube method, confirmed Esch. coli count by Eijkman test and specific intestinal pathogens, such as Salmonella, Shigella and Vibrios. Thirty out of 90 samples though free from coliforms, had viable count much higher than specified by Bureau of Indian Standard. Three samples of one of the brands which is ISI not certified had Esch. coli with most probable number 18/100 ml and Salmonella typhimurium. It is concluded that bottled water can not be taken for granted to be safe.
