Even if we prefer not to know it, faeces go out of the bathroom door. British researchers have even found on the screens of eight McDonald's tested in their study, published Thursday in the newspaper Metro. Staphylococcus or other listeria can therefore be added to your menu, without warning. But is it dangerous for your health?
In everyday life, difficult to escape the bacteria. In large numbers in the environment, even without human presence, they do not represent a risk of infection. But when we cough, many bacteria from our intestinal flora are deposited around us. If some disappear, in one or two hours, others can settle for years.

"These bacteria that we carry, which are in our flora, as our digestive tract, may be at risk," says professor of microbiology at AP-HP Jean-Christophe Lucet, specialist in hospital hygiene. Even if these "bacteria of the digestive tract are 99% harmless", they can become so if they are disseminated by a sick patient, who has not washed his hands for example.
"A mechanism of frequent fecal-oral infection"
"The fecal matter is not infective in itself, but finding these bacteria all over the shelves facilitates the spread of pathogenic bacteria to other subjects from an infected patient. It's a vicious circle, "says Lionel Barrand, a medical biologist.
"This mechanism of fecal-oral infection is common, so any contact between the feces and the mouth should be limited because it statistically increases the risk of infection. Since we do not know at the beginning who has pathogenic germs, "he continues.
The best way to protect yourself is to remind both specialists: wash your hands frequently! "We must respect the basics of hygiene rules," insists Jean-Christophe Lucet. "And do not put your hands in your mouth, avoid having germs of the digestive sphere where there should not be – screens, toothbrush – and share its germs with others. Like the contacts between toothbrushes ", advises Lionel Barrand.
