The effects of storage time on the growth of bacterial flora in bottled drinking water.
An elevated count of mesophilic and psychrophilic bacteria (10(3)-10(4) CFU/1 ml) was detected in uncarbonated bottled water stored for a period of 1 year. None of the 120 samples contained faecal coliform bacteria or streptococci. Psychrophilic and mesophilic bacteria counts detected in bottled water within 24 hours of bottling conformed to Czech Republic standard CSN 56 78 59. Counts of the same bacteria detected up to 6 months after bottling were also within the limits set by the above norm.
