The London Metropolitan University and the Metro.co.uk website have led to some restaurants failing McDonald from the UK and what they discovered were left speechless.
In fact, surveys have revealed the presence of bacteria and faeces residues on the touchscreen fast food. Therefore, on large screens located at the entrance of restaurants, there would be different types of bacteria very dangerous to human health. Specialists collected tampons at eight McDonald's in the UK, including six in London and two in Birmingham.
The touch screens we are talking about are the maxi-screens with which you order food for a few months now to avoid the line. Dr. Paul Matewele, Senior Professor of Microbiology at London Metropolitan University, explained: "We were all surprised by the intestinal bacteria and feces have been found on touchscreen machines. These cause the type of infections that people collect in hospitals Unsuspecting guests choose food on the touch screen, and then head to the server to retrieve their burgers without washing their hands. "And there, the harm is done.
But what did they find on the big screens? As Metro.co.uk explains, on one of them, it was found staph, a bacterium that can cause blood poisoning and toxic shock. "It is contagious: if you touch your nose with your fingers, then move it on the touch screen, someone else takes it and there is a nick. open, this can be dangerous, "says Matewele at Metro.co.uk.
But in addition to staphylococcus bacteria, it has also been found on touch screens Listeria. Therefore, the English maxi-screens also contained this bacterium that causes listeriosis and can lead to pregnant women who contract it. "Three quarters of the screens showed traces of bacterial proteins – continues the doctor – the proteus is found in human and animal stool". The swabs used in the investigation also revealed the presence of the bacterium Klebsiella, which can cause urinary tract infections, sepsis, diarrhea and even pneumonia.
"We are very surprised to have found so many intestinal and faecal bacteria – conclude Dr. Paul Matawele – touch screens are increasingly used, but these results advise not to eat directly after touching them, because they are unhygienic and spread diseases. "answer did not wait.
The company, through a spokesperson, said that the screens were cleaned regularly every day and that, in any case, all the restaurants were equipped with a table service before the meal.
Upstream of controversialtherefore, it should be noted that the survey only covered eight fast food restaurants in the United Kingdom. For this reason, we can not give a general picture of the sanitary conditions of all McDonald's of the world.
