“Reusable bottles carry 40,000 times more bacteria than toilet seats”

You may want to think twice before topping off your water bottle if you don’t clean it regularly.

A new study that described reusable water bottles as “portable Petri dishes” revealed they can harbor 40,000 times more bacteria than the average toilet seat.

That’s according to researchers from http://waterfilteruguru.com, who got the results by swabbing different parts of a water bottle – the spout lid, straw lid, and squeeze-top lid – three times each.

Two different kinds of bacteria were detected: Gram-negative rods, which can cause infections and are becoming increasingly resistant to antibiotics, and bacillus, which can result in gastrointestinal issues.
