Microorganisms in bottled water
background to our water drinking habits
Southern Californians seem to have a perception that bottled water is the standard for the purity and taste of drinking
water. This suggests the taste of chlorine is the key factor for the choice of bottled water over tap water.
Anadu and Harding have reported that the risk perception of drinking tap water is a subjective judgement based on taste
and odor, and the feeling the type and amount of chemical and microorganisms in water are worse than those in bottled
water. Microorganisms in bottled water.
Social, cultural and psychological factors also play a role, including the level of distrust of government
agencies. The latter is a major factor that translates into public uncertainty about safety and regulation of chemicals
in tap water. Microorganisms in bottled water. Quantifiable risks and the true differences between bottled and tap water are apparently of secondary
consequence to the consumer. The perception of risk influences people to develop what they perceive to be a preventative
action: drink bottled water. Microorganisms in bottled water.
is bottled water safe ?
In drinking water, biofilms - pathogenic bacterial like Klebsiella spp., E. coli different Pseudomonas spp.,
Legionella spp., Mycobacteria, and other organisms like protozoa (amoebas), parasites (cryptosporidia and giardia)
and also enteroviruses have been detected.
Selected Contaminants of Potential Concern for Bottled Water :
Coliform Bacteria, a broad class of bacteria used as potential indicator of fecal contamination, may be harmless of
themselves. Microorganisms in bottled water. Harmful types of coliform bacteria (such as certain fecal coliform bacteria or E. coli) can cause
infections with vomiting, diarrhea, or serious illness in children, the elderly, and immuno-compromised or other
vulnerable people. Microorganisms in bottled water.
Heterotrophic Plate Count (HPC) bacteria are a potential indicator of overall sanitation in bottling and source water,
although may may be harmless of themselves. In some cases they may indicate a presence of infectious bacteria sometimes
linked to illnesses and they can interfere with the detection of coliform bacteria or infectious bacteria. Microorganisms in bottled water.
Pseudomonas aeruginosa bacteria are a possible indicator of fecal contamination or unsanitary source water or bottling and
can cause opportunistic infections.
In conclusion - Microorganisms in bottled water - it seems to be a bit of a lottery
