The next time you use a touch screen for auto-order at McDonald's, you may get some "free secondary orders". Listeria, staphylococcus, and a bunch of other bacteria found in the poop. Mmmm, I like it!
A recent survey showed that McDonald's touch screens are covered with a number of potentially disturbing and contagious strains of bacteria. London Metropolitan University microbiologists recently performed touchscreen swab analysis at eight McDonald's restaurants in the UK, six in London and two in Birmingham, as part of a survey conducted by Metro.co.uk.
Samples from all branches contained coliform bacteria, a broad class of bacteria found in the poop of all warm-blooded animals and humans, as well as Bacillus bacteria. They also discovered Listeria bacteria in two branches of London. Generally associated with a food-poisoning-like illness, it can be life-threatening if you are pregnant or if your immune system is weakened.
"Listeria This is another rare bacterium that we were shocked to find on touch screen machines, as this can again be highly contagious and a problem for people with weakened immune systems, "said Dr. Paul Matewele , a microbiologist at London Metropolitan University. Metro.
A screen in a branch office has been found to host staphylococcus, a group of bacteria that may be responsible for staph infections. Other bacteria found on screens include Pseudomonas; responsible for chest infections, Enterococcus faecalis; found in the gastrointestinal tract of the human, and Klebsiella; associated with urinary tract infections, sepsis and diarrhea.
"Enterococcus faecalis is part of the flora of the gastrointestinal tract in humans and other healthy mammals. It is notorious in hospitals to cause nosocomial infections, "added Dr. Matewele.
In defending the findings, a spokesman for McDonald's said, "Our screen screens are cleaned frequently throughout the day. All our restaurants also offer guests the opportunity to wash their hands before eating. "
So, how bad should you be?
Well, bacteria are an integral part of our world. They are literally everywhere, from your face to the opening of a hydrothermal vent on the high seas, or from this ATM, you have received money this morning. Some of them are harmless, others are harmful and others, in fact, beneficial.
Obviously, the idea of touching a slightly greasy screen covered with germs just before eating is not very appetizing. However, as long as your immune system is in good shape, you should not have too much to worry about. Many of these bacteria seem more frightening than they are and in small numbers, it will not hurt you.
That said, washing your hands quickly with soap and warm water before eating in public is probably not the worst idea in the world.
Enjoy your meal!
