A study conducted by Paul Matawele, a professor of microbiology at Metropolitan University in London, revealed faeces on touch screens of various McDonald's establishments in the British capital and Birmingham, local media reported Wednesday.
In all devices analyzed in the premises of the popular American fast food chain Six, in London and two in coliform bacteria of Birmingham, were discovered. "We were all surprised by the amount of intestinal and faecal bacteria Matawele added that this caused the type of infections that led people to the hospital.
Staphylococci have also been found which can cause blood poisoning or toxic shock syndrome. Added to this is the bacterium Listeria, which can cause spontaneous abortion or fetal death in pregnant women, as well as the proteus bacteria in human and animal excreta, which can cause urinary tract infections, all highly contagious, said Matewele.
In the opinion of the British scientist, the disinfectant used to clean these screens "could not have been powerful enough" because the aforementioned bacteria would manage to stay in such devices for days.
