to re-use or not to re-use

You might be helping the environment when you re-use water bottles, but researchers say you could also be risking your health. A study of kids’ re-used water bottles at a Canadian secondary school found the kinds and levels of bacteria that would prompt a health department warning to boil tap water. About a third of the samples were contaminated, some with feacal bacteria that probably came from the kinds’ hands and mouths as they repeatedly used the same bottles without washing them. However, study suggests the kind of washing needed to kill the bacteria might accelerate the breakdwon of plastic, potentially causing the toxic chemicals (DEHA) to migrate into the liquid.

Food safety and plastics experts contend, however, that many bottles are safe as the are made with non harmful substance (i’d rather not mention abbreviations to express the content more effeciently). Although these so called non-harmful bottles are design for single use, the can be re-used without any health risk provided that they are cleaned and handled hygienically…tadaaa.
