the hardest 'which has more germs?' quiz you'll ever take

From toilet seats to door handles, we all think that we know the most common places where unwanted germs and bacteria are found, and take steps to avoid coming into contact with them. Whether that’s opening doors with the backs of our hands, or lining the toilet seat with toilet tissue before sitting down, we all have our go-to techniques that we believe will keep the germs away from us!

But when it comes to those germ hotspots, are we really looking in the right places? You may be surprised as to where the bugs are really found – and your regular cleaning routine may never be the same again!

The surprising places where germs are lurking


It’s perfectly reasonable to believe that in a public or workplace washroom, the dirtiest place would be the toilet seat. However, it’s been scientifically proven that toilet seats are actually one of the cleanest places in the room, and that there are countless everyday items and places that tend to be far dirtier – in fact, you’re probably using one of them right now!

A study conducted by Dr. Charles Gerba, professor of microbiology at the University of Arizona, revealed that with 25,000 germs per square inch, mobile phones carry 10 TIMES more bacteria than most toilet seats. This is because toilet seats tend to be cleaned regularly with washroom cleaning products, whereas mobile phones are not, and they’re also touched and handled many times throughout the day.

So when you’re working hard, your immune system clearly is too!

  • Handbags – Women aren’t off the hook either. Good Housekeeping Institute found that the bottoms of handbags are one of the worst places in the household for germs, as they’re often placed on floors
  • Kitchen sinks – The NHS claims that kitchen sinks can contain 100,000 times more bacteria than a toilet, so make sure it’s cleaned daily with a food safe surface cleaner
  • Laundry – Your supposedly clean load of washing may be the opposite.

  • Kitchen sponges – A study published by Scientific Reports revealed that kitchen environments harbour more bacteria than toilets, with kitchen sponges being the worst cuprits
  • Carpets – Research conducted by microbiologist and immunologist Philip Tierno Jr., Ph.D. found that carpets contain so much bacteria that they can be up to 4,000 times dirtier than a toilet seat
  • Washroom sink taps – An infographic published by PlumbWorld claimed that washroom taps have been found to have 21 times more germs than toilet seats, as they’re the last spot touched before you wash your hands
  • Light switches – The infographic also claimed that light switches, which may be touched by multiple people throughout the day, can have over 200 bacteria per square inch

Protecting yourself from germs in public places


Even if you still can’t bring yourself to stop covering the toilet seat with paper before you sit, here’s something to consider: it can actually make germs more likely to come into contact with your skin.

That’s because toilet seats are designed to prevent bacteria from spreading in the first place. They have smooth, rounded plastic surfaces that make it difficult for germs to attach to them. In fact, Professor Val Curtis from the London School of Hygiene and Tropical Medicine told The Huffington Post UK that any bacteria living on a toilet seat would most likely be “dead” within an hour.

On the other hand, toilet tissue is absorbent and is kept next to the toilet – which makes it more likely to absorb germs from the air when the toilets are flushed. So when you sit down on toilet paper, you’re exposing yourself to more bacteria – although it’s incredibly unlikely that you’ll get sick from a toilet seat, whether it’s lined with toilet tissue or not.
