Researchers have discovered that mobile phone carry more bacteria than you will find in a toilet!
The research test shows that there was up to 10 times the amount of bugs which can cause nausea and stomach problems than were present in a lavatory.
But experts said that the reason is that phones are often passed between people which spreads the germs around - but they are never cleaned - which means the diseases keep on building up.
Charles Gerba, a microbiologist at the University of Arizona, said in his ongoing experiments, that he has found that bugs get onto a phone because it is so close to our hands and mouths.
When somebody lets a friend or a stranger use their mobile then the bacteria gets onto the device easily.
He added that because mobiles are electronic some people are reticent about cleaning them.
Phones are just not part of our cleaning routine whereas we should think about giving them a wipe with an antibacterial substance every now and then.
Previous research has found that other things we assume are clean are in reality rather disgusting.
Also, scientists discovered that cash machines have similar levels of pseudomonads and bacillus, bacterias which are known to cause sickness and diarrhoea, as they found in public toilets. Computer keyboards are also five times dirtier than the average lavatory seat - because of food poisoning bugs e.coli, coliforms, staphylococcus aureus and enterobacteria found there.
