Bottled water or tumbler that can be used many times, can reduce the use of disposable plastic. In addition, the use of drinking bottles can also save you money.
However, do you know the provisions on how often to drink water bottles must be washed? A microbiologist warns of a threatening danger if we do not often clean drinking water bottles.
Reported by Country Living, experts suggest, you need to wash the drinking water bottles thoroughly, once a week with hot soapy water. It will eliminate various bacteria that are in bottled drinking water.
In Langone Medical Center study, it turns out that many bacteria survive in and around drinking water bottles. By rubbing 12 different bottles of drinking water, the research team found that there were more than 300 thousand colony-forming units (CFU) per square centimeter in several bottles of drinking water.
The laboratory looked at the four most popular types of bottles and found that one that had a slide- top holds more than 900 thousand CFUs on which the lips touch the rim. That fact shows us the importance of cleaning drinking water bottles regularly, not just rinsing them.
Clinical pathology and microbiology professor at NYU Langone Medical Center, Philip Tierno underscores the importance of rubbing the inside of drinking water bottles. “Just rinsing won’t work (in eliminating bacteria),” he said.
Experts raised the importance of using a bottle brush to clean the inside and outside. Because having just a less unclean condition can make the accumulation of bacteria which is dirtier than soap impurities in the bathtub. Therefore, he suggested washing bottles every few weeks to clean them.
