Next time you use a mobile phone, you might want to give it a little clean.
There are more bacteria on the average mobile than you will find in a toilet, researchers have discovered.
In tests there was up to ten times the amount of bugs which can cause nausea and stomach problems than were present in a lavatory.
Experts said the reason is that phones are often passed between people, which spreads the germs around, and they tend to be rarely cleaned, which means the diseases keep on building up.
Charles Gerba, a microbiologist at the University of Arizona, said that during his experiments he has found that bugs get on to a phone because it is so close to our hands and mouths.
When somebody lets someone else use their mobile, their bacteria easily gets on to the device too.
Professor Gerba added that because mobiles are electronic some people are reticent about cleaning them.
Phones are simply not part of our cleaning routine, but we should think about giving them a wipe with an antibacterial substance every now and then.
Previous research has found that other objects we assume are clean are quite the opposite.
Cash machines have similar levels of pseudomonads and bacillus - bacteria known to cause sickness and diarrhoea - to those found in public toilets.
Computer keyboards are also five times dirtier than the average lavatory seat.
