You take your favorite water bottle to work, at the gym, and then refill it for next day’s use.However, the question is, how often are you washing your water containers?


While most people assume that because “it’s only water and only they use the bottle, so there is no risk.” On the contrary, “bacteria and other microorganisms can accumulate in the bottle — forming biofilms on the surfaces — and also on the opening of the bottle that is in contact with the mouth and hands,” said Dr.Elizabeth Scott, a biology professor at Boston’s Simmons College, told Global News.


According to a recent study, the average water bottle has about 313,499 CFU (or colony-forming units of bacteria) compared to 2,937 CFU on a pet’s chew toy.The study also found that:


* Slide-top water bottles carried the most germs at 933,340 CFU


* Squeeze-top bottles had 161,971 CFU


* Screw-top bottles had 159,060 CFU


* Straw-top bottles had only 25.4 CFU


Alarmingly, the report also said that “the spot your lips touch...has over 900,000 CFU/sq cm on average.”


Dr.Scott did note, "Most are probably harmless environmental microbes but also some potentially harmful germs or pathogens, such as bacteria.Most germs thrive on wet surfaces and can replicate within hours.Within a few days, your bottle could develop a biofilm, especially on the bottom where people rarely thoroughly get to clean.


If you’re adding cucumber, lemon or berries to your water, it will increase your chances of growing bacteria in your water container.


With this, experts suggest washing water bottles each time after use with hot water over 71 C, and use soap with some kind of cloth or sponge and make sure you’re giving your bottle a thorough rinse.Then, dry your water bottle after that.


At the end of the day, it’s our job to keep our utensils clean with regular washing and rinsing.
