There’s no doubt that reusable water bottles make a big different to the environment and can save you money. However, this does mean having to pay more attention to hygiene.
One microbiology study of reusable plastic water bottles recently revealed a high degree of bacteria forming, inside both the bottle and the area around the cap, especially where our lips touch the rim.
Got the heebie jeebies? No need to panic. To combat this problem, the scientists recommend regularly cleaning the bottle, both inside and out with soapy water, at least once a week was essential to prevent regrowth.
Dr Philip Tierno, clinical professor of pathology and microbiology at NYU Langone Medical Center, who headed up the study, emphasized: ‘it’s imperative to scrub the inside of the bottle, too. Merely rinsing is not going to do the trick’.
In addition, they also suggested an occasional high temperature wash in the dishwasher to kill off any residual bacteria that may be lingering in hard-to-reach places.
Interesting, bottle design also seems to play a role in hygiene levels. Of the four most popular types of drinking bottle, the study found that the one with the slide-top tended to collect the most germs.
