Your mouth is undoubtedly the dirtiest part of your body. It has the largest amount of bacteria because it comes into contact with so many different germs each day. In fact, Dutch researchers actually conducted a study about kissing.
The mouth is undoubtedly the dirtiest part of your body with the largest amount of bacteria. The mouth comes in more contact with germs than the rectal area.
Your gut is home to most of the microbes in your body, but your skin, mouth, lungs, and genitalia also harbour diverse populations. And as research continues into body biomes, it should reveal answers about how these microorganisms are promoting health or even disease.
Staphylococcus, Corynebacterium and Propionibacterium represent the dominant bacterial genera on skin and illustrate how bacteria adapt to life in this harsh environment and also provide us with unique benefits.
Cutting boards
University of Arizona researchers found that the average cutting board has 200 times more fecal bacteria than a toilet seat. Fecal bacteria originate in animals' internal organs, and the knife grooves you leave when you are cutting meat are the perfect conditions for germs to live and fester.
The cleanest part of the human body is often considered to be the eye because of its abilities to clean itself. The eyelid opens and shuts several times every minute in order to keep the eye clean and moist.
The cleanest thing in the world is a special clean room, with only about 100 germ particles per cubic foot. Your room probably has more like 500,000 to 1 million particles per cubic foot. Scientists use clean rooms to study things without contamination from bacteria or viruses.
Your cutting board. University of Arizona researchers found that the average cutting board has 200 times more fecal bacteria than a toilet seat. A big culprit: raw meat, since many fecal bacteria originate in animals' internal organs.
The microwave and refrigerator doors and the faucet are all covered in bacteria. The vending machine buttons aren't that clean, either. And the damp, dark reservoir in your coffee maker could be full of yeast and mold. Wash your hands before and after you touch the appliances.
Belly button or the navel is probably the most ignored part of the body. If it is not cleaned regularly, it will not only lead to buildup of dirt but also bacteria. The dark, moist environment of the belly button is ideal for breeding of bacteria.
Mouth. Mouth is one of the dirtiest places of the human body. There are more than 700 million different types of bacteria living in an average person's mouth. These bacteria feed and multiply in your mouth, especially, the Streptococcus bacteria which feed on sugar and starchy carbohydrate foods that you consume .
These produce a slow, burning pain; the faster the neurons fire, the more intense the pain. The tongue, lips, and fingertips are the most touch- sensitive parts of the body, the trunk the least.
The bathrooms are usually the hardest room to clean, and so they're a great place to start. Work from the top down, wiping down surfaces, scrubbing out the sink, then the toilet, bath and shower, and finish with the floor.
The average office desk is said to contain 400 times more germs than a toilet seat – meaning that many office workers could be at risk of sickness due to dirty desks.
Q-Tips, Cotton Pads or Other Cotton Products
Cotton balls, cotton pads, and Q-Tips are definitely not safe to flush — they don't break down the way toilet paper does, and all they really do is clump together in your pipes and cause problems down the line.
Speaking of mites that feed on human material, Demodex folliculorum (Simon) is one of three mite species living on your face. The microscopic critters are found across the human body, but are particularly dense near the nose, eyebrows and eyelashes.
On a microscopic level, our faces have their own very active populations. Inside the pores on our faces live a host of tiny mites known as Demodex. These little inhabitants of our skin are roughly 0.3 milimeters long – around half the size of the side of a credit card.
Chiggers. Chiggers go by many names: harvest mites, red bugs, scrub bites, and bête rouge. These bugs are part of the mite family called Trombiculidae, and are found worldwide, although only two species affect North Americans.
If you wear shoes, most likely there will be more on the palms of our hands. And even if you don't wear shoes, it is more likely your hands will have more germs, bacteria on them.
LendEDU pointed to research from Mastercard and the University of Oxford, which found the average bank note is home to 26,000 types of bacteria including E. Coli. “And the average coin has more germs than on a toilet seat!”
Money can carry viruses, protozoa, and bacteria. Depending on where it's been, it could carry almost anything. One old and widely-cited study even found that 79% of one-dollar bills contain traces of cocaine.
