Reusable bottles can contain 40,000 times more bacteria than the average toilet seat, says a recent study.
When compared to other household objects, the study found that reusable water bottles contain twice as many germs as a kitchen sink, 4 times the amount of bacteria as a computer mouse, and 14 times more than a pet’s drinking bowl.
