Both oral and environmental bacteria and viruses could be building up on reusable water bottles that are not cleaned on a regular basis, according to a scientist from the Center for Ecology and Hydrology.
Senior scientist Andrew Singer was recently interviewed by the Huffington Post UK, where he explained that even E. coli could find its way into an unclean reusable water bottle.
“When you flush the toilet, the toilet water will get aerosolized and a fraction of the water droplets can land on and in your water bottle,” Singer explained.
Singer said that poor personal hygiene habits, such as rarely or not washing your hands after using the toilet, or taking your water bottle to the toilet with you, could increase the chances of getting serious infections.
