8 out of 10 phones harbor organisms which could cause diseases.

Telephone handsets can be a breeding ground for dangerous and contagious bacteria that can be a cause of unnecessary ill health and absenteeism.

A study conducted by the University of Arizona concluded that telephones can be contaminated with up to 25,123 germs per square inch, and that telephones have 500 times mo re bacteria than the average toilet seat.

The population of germs and bacteria can include E.coli, Streptococcus, Salmonella & Staphyloccus aureus, all potentially dangerous and contagious organisms. The same bacteria can be found on telephone headset voice tubes and ear cushions, but unlike a telephone handset, these are cheap to replace and renew, making headsets a healthier alternative.

Voice tubes can also become blocked with food, make-up and dust. This is not only unhygienic, but it also compromises the effectiveness of microphones, which causes lowered volume levels for both callers and headset wearers, compromising their effectiveness.

The UK Health & Safety Executive advises "There may be an increased risk of infection because headsets are worn so intensively. The issue of headsets to individuals is strongly recommended. If sharing from a pool of headsets is unavoidable, then each call handler should be issued with their own personal foam ear pads and voice tubes."
