Money:Upon analyzing a randomly sampled stash of paper money, researchers at the Wright Patterson Medical Center in Ohio actually found that a majority of paper bills have enough bacteria to give someone with a compromised immune system (HIV or cancer) some serious problems.
Bathroom Stall Handles and Locks: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.
Crosswalk Button:Crosswalk buttons were actually found to have high levels of adenosine triphosphate (ATP), a molecule that signals the presence of yeast, bacteria, and mold cells.
Vending Machines: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.
Public Sinks:With over half a million bacteria per square inch this is surely one of the dirtiest places.
Remotes: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.
Parking Meters:According to a recent study 40 percent of parking meters and kiosks were labeled as being a high risk for illness transmission.
Mailbox Handles: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.
Light Switches:Like numerous other entries on this list, lightswitches often suffer from the “never been cleaned” sydnrome.
Fridge Door Handle:People often take meat, amongst other things, out of the fridge, make themselves a sandwich, and then return it with without rinsing their hands. Think about it.
Gas Pump:Gas pumps are consistently ranked by studies as one of the dirtiest places that we regularly stick our hands.
Drinking Fountains:With school fountains being the worst, they can have over 2.5 million bacteria per square inch on their spigots.
Escalator Railings:Topping the list of the world’s most useless bacteria infested things, unless you find some pressing need to stabilize yourself, we suggest you stear clear of the hand rails.
Door Knobs:Although modern knobs are usually designed to be bacteria resistant, these types of defenses aren’t always effective. Older non-resistant door knobs are going to be even worse.
Cell Phones: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.
Credit Card Machines:Just like with ATMs you’ll find some nasty stuff growing on those keypads.
Shopping Carts:Researchers at the University of Arizona recently found that shopping carts had more bacteria, saliva, and fecal mater than public bathrooms, telephones, and even those nasty escalator handrails.
ATMs:Recent studies found ATMs to have high levels of bacillus and pseudomonads, two bacteria famous for causing sickness and diarrhea.
Toilets:Statistics tell us there are about 295 bacteria per square inch covering this shiny surface.
