The 25 Dirtiest Things You Touch Every Day

Posted by on March 27, 2012

Although you can’t see them, they’re everywhere. They’re on everything you touch, everything you eat, and they even live inside of you…by the millions. What are they? They’re bacteria, and without them we would all die. But wait, aren’t bacteria the bad guys? Well, yes, in many cases they are. Bacterial infections kill countless people every year, but that doesn’t mean they are all inherently bad. This is because their lethality at least partially depends on where they are inside your body. For example, while your guts are teeming with E. coli  that help you digest your food, it’s when they get your bloodstream that you have a problem. So, just remember as you read through this list of the 25 dirtiest things you touch every day that sometimes a little bit of dirt might actually be good for you.


Door Knob

Although modern knobs are usually designed to be bacteria resistant, these types of defenses aren’t always effective. Moreover, older non-resistant door knobs are going to be even worse. Keep this in mind next time you are trying to escape a public bathroom.


Fridge Handle

Let’s be honest, how often do you clean your fridge handles? Probably never. You should consider it though, because they are often infested with the same bacteria that live on poultry and pork. The reason for this is that people usually take meat out of the fridge, make themselves a sandwich, and then return it with without rinsing their hands.


Vending Machine Buttons

Next time you use a vending machine consider this – you are probably swallowing more than just your favorite snack. As dirty as the buttons on that machine are, most of your selection consists of finger food which gives the bacteria a fairly direct path to your esophagus.


Parking Meters

According to a recent study 40 percent of parking meters and kiosks were labeled as being a high risk for illness transmission. Who knew parking your car could be so dangerous?


Crosswalk Buttons

Looking both ways before crossing the road may not be enough to stay out of the dangerzone these days. Crosswalk buttons were actually found to have high levels of adenosine triphosphate (ATP), a molecule that signals the presense of yeast, bacteria, and mold cells.



Recent studies found ATMs to have high levels of bacillus and pseudomonads, two bacteria famous for causing sickness and diarrhea. Interestingly enough these are the same bacteria that infest public toilets. So next time you reach to type in your PIN number just imagine yourself running your hand around the rim of the toilet bowl across the street.


Remote Control

While the cleanliness of your remote control at home will depend upon your own personal hygeine, know this – public remotes at hospitals, hotels, etc. are filthy little creatures. Not only do their cracks and crevices make them ideal for microbes, spores, and bodily fluids to hide but studies have found semen, urine, and even SARS on public remotes.


Toilet Seat

Although you’d probably have to be pretty thirsty to drink from a public toilet, as you can see it is certainly not the dirtiest thing you come in contact with on a regular basis. We still don’t recommend quenching your thirst from it though, as the statistics tell us there are about 295 bacteria per square inch covering its shiny surface.


Cell Phone

Yup, it’s dirtier than your toilet seat. The reason for this is that phones are generally warm and like the tv remotes they have numerous crevices for bacteria to hide in. A recent study in the United Kingdom even found that some cell phones can be staph bacteria breeding grounds, which can lead to everything from skin infections all the way to meningitis.


Inside Latch of Public Bathroom Stall

At least the inside of the toilet bowl gets rinsed off a little bit with every flush, the latch on the door though…probably never. In fact, theres a good chance that since the stall was constructed it hasn’t been cleaned at all. Just another reason to wash your hands.



Unless you’re cleaning your bathtub weekly then most likely whatever is lingering around your drain is going to be worse than whatever you find in your toilet. Staph infections, pneuomonia, septicimia, and urinary tract infections have all been caused by dirty tubs.


Light Switch

Like numerous other entries on this list, lightswitches often suffer from the “never been cleaned” sydnrome. And after years of being flipped up and down by thousands of fingers they tend to end up with hundreds of bacteria per square inch. Just make sure that you’re not the last person to leave the conference room!


Microwave Pads

While you may keep your own personal microwave clean, how about at work? Even if you did decide to do everyone a favor by washing it down, just using soap and water won’t be enough to get rid of all the grease. In fact, unless you attack it with bleach you’ll have yourself a nice little bacteria colony growing right next to where you heat your food.


Elevator Buttons

It shouldn’t be too surprising to see these on here. They’re pretty much exactly like switches except they get flipped way more often.


Mailbox Handles

Surprised? The same study that found crosswalks, ATM buttons, and parking meters to be bacteria hotspots also listed mailboxes right behind gas pumps as one of the most infested things people touch on their way to work.
