Microbiologists around the world have studied washing machines, a dirty underwear with an average of 0.1 grams of faeces, excreta, Salmonella, Escherichia coli and other germs, even if properly cleaned, dried, the above bacteria can not be completely killed.
One gram of faeces contains 1000 viruses. One gram of faeces contains 1000 viruses, 100 bacteria, and 10 parasite cysts. Although some bacteria and viruses are good for the human body, most bacteria and viruses are harmful to people.
Especially when faeces contaminate water, food, cutlery and clothing, most harmful microorganisms enter the body and cause harm to people. As early as 1964, Dr Cameron, who examined the underwear of 940 men in Oxfordshire, England, found that the men had different levels of faecal contamination from "wasp color" to "large amounts of faeces" on their underwear, so Dr Cameron lamented: " There are so many people in our countrymen who whine about small things like a little bit of ketchup on the tablecloth of a restaurant, but at the same time they sit in luxurious chairs and eat beautifully in their faecal-stained underwear. ”
