- Licking your home toilet seat could be safer than drinking using reusable drinking bottles
- The amount of bacteria contained in a slide-top drinking bottle is equivalent to 900,000 CFU/sq. cm.
- Amount of bacteria contained in an average home toilet seat: 27 CFU/sq. cm.
A recent study conducted by Emlab P&K thru the initiative of Tread Mill Reviews found out that drinking using reusable drinking bottles could bring more harm than licking your home toilet seat or your dog’s toy.
It was revealed that drinking bottles contain an alarming number of more than 300,000 colony (forming units per square centimeter or CFU/sq. cm.) of viable bacteria.
Slide-top drinking bottles topped having an enormous bacteria content of 900,000 CFU/sq. cm. as an average, squeeze top bottles followed with nearly 162,000 CFU/sq. cm., then the screw-top containers with hosts under 160,000 CFU/sq.cm.
The straw-top bottles, meanwhile, came to be the least bacteria-populated with just 25 CFU/sq. cm. The possible reason, posted Tread Mill Reviews on their website, it is a less attraction to moisture-loving germs since the water drips to the bottom of the straw.
The bacteria content of the straw-top bottles, however, is approaching close to the home toilet seat’s average of 27 CFU/sq. cm.
Interestingly, 98-99% of the germs on the squeeze-top and the screw-top bottles are of bad kinds which could bring pneumonia and blood infections, and can even resist antibiotics.
Straw-top bottles, surprisingly, contain most harmless germs.
The study investigated swabbed lids of 12 reusable plastic bottles used by athletes – that has not been washed for a week. Three drinking bottles for each type (screw-top, slide-top, squeeze top, and straw-top).
Tread Mill Reviews made clear that the study is not aimed to discourage people in using their reusable drinking bottles but to give awareness of the potentials for contamination.
The website added, stainless steel is a better choice than plastics when it comes to bottles and bacteria, and water bottles without cracks and tough-to-clean spots are less likely to host germs.
They recommend to dish-wash or hand wash drinking bottles after every use and you can even use a weak bleach solution like a sanitizer.
