A British study found that the touch screens that you use to order food at McDonald's restaurants carry traces of human poo.
A survey was conducted in six London branches of the fast food chain and it was found that every screen of McDonald's cleaned up had a poop bacterium.
"We were all surprised by the amount of intestinal and faecal bacteria present on touch screen machines," said Professor Paul Matawele, a lecturer in microbiology at London Metropolitan University.
The results of the samples taken showed listeriosis on the screens, which can cause illness and diarrhea and be fatal in extreme cases.
"These cause the type of infections that people contract in hospitals."
