Sometimes we all take a phone into the toilet. But it is a very dangerous habit! You can expose yourself and others to germs like salmonella, E. Coli and C. “If you wipe your bum then pick up your phone, you may as well not bother washing your hands because all the bacteria you put on your phone will end up back on your hands,” hygiene expert Dr. Lisa Ackerley told.So what we all should do? Dr. Ron Cutler, director of biomedical science degrees at Queen Mary’s University London, said: “Basically, you just shouldn’t (take your phone into the toilet) if you are at all concerned about the transfer of viruses and fecal contamination.” He said that levels of contamination vary widely depending on where the toilet is. A small office may not be a problem, but a hospital or a cruise ship where viruses may be circulating are different.
