Excreta would be on most McDonald's control terminals

According to a study at London Metropolitan University, traces of human excreta would be found on a large part of the automatic order windows used in McDonald's restaurants.

Samples were taken from eight restaurants in the United Kingdom, and coliforms – bacteria contained in human excreta – were found on all test sites.

Customers use these kiosks to place orders and pay for food before eating.

According to the D^r Paul Matawele, from the Department of Microbiology at London Metropolitan University, the touch screens are cleaned, but not rigorously enough.

"This type of bacteria can survive on machines for several days," he said.

The investigation was conducted jointly by the Department of Human Sciences of the renowned university and metro.co.uk.

"We were all amazed by the amount of bacteria found on these machines. They can lead to the same infections that people get in hospitals. "

A McDonald's spokesperson argued that the control screens are cleaned daily.

"All our restaurants are also equipped with places for our guests to wash their hands before eating," he added.

McDonald's began introducing the kiosks in its restaurants in 2015 and hopes to have all of its facilities in place by 2020.

These terminals add to the long list of objects that are constantly covered with excrement.
