i think that if its not open then its okay but i tink the only way that bacterial will form is everytime u take a drink out of it with ur mouth.
Reply:The fact that it's sealed makes all the difference. It's basically sterile. So it should be fine to drink.
Reply:The only way bacterial growth will occur is if the seal is broken and bacteria is introduced (by drinking from the bottle). Even if the seal has been broken, if nothing has had contact with the water in the bottle (lips, fingers), no bacterial growth will occur.
Reply:NO.





Bacteria does not mysteriously appear.





If bacteria was in the bottle (never opened) in the first place then only a slight problem exists (vary rare). It depends on the cell count to be sure of any health concern and for this a lab would be helpful.





Bacteria need a certain temp. (strains vary on this), a food source, and water in order to reproduce. Well there is plenty of water but no food in your water bottle. It is safe. If you have opened it and subjected to these extremes of temp. still your biggest concern is quality not health. Molds would then be your concern. Just a flavor thing.





Drink up %26amp; enjoy.
