Reusable Water Bottles Hold 40,000 Times More Bacteria Than A Toilet Seat: Study

According to a study conducted by waterfilterguru.com, reusable water bottles hold 40,000 times more bacteria than a toilet seat.

A new study has found that reusable bottles can harbor around 40,000 times more bacteria than the average toilet seat. 

A team of researchers from US-based waterfilterguru.com swabbed different parts of water bottles including the spout lid, screw-top lid, stray lid and squeeze-top lid, three times each, and found two types of bacteria present – gram-negative rods and bacillus, HuffPost reported.  

“They are objects that can’t betray us,” Australian Catholic University clinical psychologist and hoarding disorder expert, Associate Professor Keong Yap, said, comparing the phenomenon with objects children use to soothe anxiety (like stuffed toys). “They are reliable and predictable, unlike people who can hurt us,” Mr Yap added. 

In their study, the researchers explained that while gram-negative bacteria can cause infections that are increasingly resistant to antibiotics, certain types of bacillus can result in gastrointestinal issues. They compared the cleanliness of the bottles to household objects and stated that they contain twice as many germs as the kitchen sink, can harbour four times the amount of bacteria as a computer mouse and 14 times more than a pet’s drinking bowl. 

A new study conducted by Japanese scientists found pathogenic bacteria and fungi on the masks of 109 volunteers between the ages of 21 and 22.

  1. Maybe people should wash & dry their water bottles like they do the rest of their dishes. The hard to clean fancy tops may need a soak in chlorinated water before rinse & dry as well as some brush scrubbing in difficult to reach areas.
