Following a study carried out by professor Paul Matewelle from the London Metropole University which appeared in the Metro, it appears that tactile screens in McDonald’s are covered in traces of excrement. However these traces are also accompanied by a whole host of unimaginable bacteria and illnesses which shouldn’t be found in a “restaurant”. Read on to find out more.
Eight British McDonald establishments were tested in total in London and in Birmingham by Professor Paul Matewele. What was the aim of the study? The professor wanted to analyse the touch screens of the fast-food giant. These screens are touched by thousands of people everyday so that they can order food. Of course consumers never wash their hands before or after ordering food on the screen. They tap the screen, place their order and then they go and eat.
So what can be found on touch screens like this?
Samples were taken from all the screens in the British sites and then placed in petris dishes so the bacteria could be identified. This is when worrying details became apparent.
Dangerous bacteria on the touch screens
The results were mind-boggling but not in the good sense of this term. Professor Matewele and his team said themselves that they were “surprised about the quantity of intestinal and fecal bacteria found on the touch screens. These bacteria can cause types of infections that people can contract in hospitals. “
Worryingly, bacteria that we only generally find in hospitals have landed on screens which we touch just before we go and eat… The London team have researched several elements including:
- Enterococcus faecalis: In general, this bacterium is part of human and animal intestinal flora. It is not uncommon to find it in hospitals. Nevertheless, it can lead to nosocomial infections.
- Staphylococcus: This bacterium can cause blood poisoning or even toxic shock syndromes. It is absurd to find a staph in a place like McDonald’s. Even Professor Matewele was alarmed as this bacterium is very contagious and dangerous.
- Listeria: This bacterium was found at the Birmingham sites and is known to cause miscarriages and weaken the immune system of the infected patient. Again, this bacteria is rare, and finding it in a fast food restaurant is worrying.
- Proteus: This bacteria can be found in human and animal excrement. This bacterium is dangerous as it can cause septicemia (in hospitals).
Other worrying bacteria were also found by those in charge of the laboratory.
Following this research those responsible at McDonald establishments have defended themselves by saying that their screens are cleaned several times per day. However despite this these bacteria have managed to get into the slightest of corners. When you think that thousands of people pass their fingers over these machines it is understandable that they should be constantly well disinfected so no bacteria stands a chance. Even if someone is very careful about their hygiene, one single contact with a contaminated screen can make you lose your perfect standards.
Put simply if you use these machines then you should always remember to wash your hands before and after. If you are using a machine, rather than pressing with the tips of your fingers you could use one of your knuckles. However the best idea is really to make your own homemade burgers as you know exactly what you are putting in and you are responsible of your hygiene!
