How dirty are plastic water bottles?

New research shows that reused plastic water bottles contain an average of 300,000 bacterial colonies per square centimeter, dirtier than a dog bowl.

"Drinking water from a reusable plastic bottle is dirtier than eating rice from your pet's bowl", says the Treadmill Reviews site.

According to Telegraph, the above conclusion was made after the research team of Treadmill Reviews tested 12 types of plastic water bottles used by athletes. After a week of use without washing, the plastic bottles contained an average of 313,499 bacteria per square centimeter. The dirtiest sample had up to 900,000 bacteria per square centimeter, more than a toilet bowl, and 60% of these can be harmful to human health.

Experts explain that not washing is the main reason why plastic bottles are unsanitary. In addition, sweat and germs you come into contact with every day also dirty plastic bottles. To improve this situation, you should wash the bottle daily or switch to using a stainless steel water bottle.
