It would almost make you afraid of contamination, so often we read about new facts about how dirty something actually is. The average handbag is dirtier than a toilet, your dishcloth already harbors four billion bacteria after 24 hours and most phones contain poop bacteria. Just to name a few. Damn. Well, we have another revelation for you.
Shoes off or on indoors?
Some families have a sacred rule that every guest leaves their shoes by the doormat. Have you always rolled your eyes at this? Then we have news for you.
On average, around 421,000 bacteria live under your shoes, including nine different types of stains. This is evident from a study by the University of Arizona. The infamous poop bacteria E.coli, Serratia ficaria and Klebsiella pneumoniae have been found under most shoes. If you are unlucky and come into contact with these pathogens, you can contract diarrhea, respiratory infections and urinary tract infections.
When you think about it, it’s not surprising that wearing outdoor shoes indoors isn’t exactly good for your health. “We walk through things like bird droppings, dog droppings and bacteria in public toilets. All sources of E.coli bacteria,” explains Professor Kelly Reynolds.
Toxins
But there’s more. Spreading poop bacteria throughout your home isn’t the only thing you should worry about. A scientific study from Baylor University found that the toxins from asphalt roads covered with coal tar can increase the risk of cancer. The toxins can stick to your shoes like dust particles.
