Look who spreads germs in public toilets
There is an ongoing bout in public toilets. Apart from the toilets that send out a mist of poo every time they are flushed, and bacterialaden door handles and soap dispensers, there is the infamous hand dryer that distributes germs from faeces and urine to all and sundry.
But who is the worst offender?
Studies all agree on the importance of thoroughly washing hands but nobody has been able to pinpoint the cleanest way to dry them later. One study, which found that hand dryers increased the spread of bacteria, was funded by the European Tissue Symposium, a trade association that represents tissue paper producers in Europe. Dyson, the manufacturer of a hand dryer, paid for another study that recommended the company’s contraption. Confused? Behold an independent study, which compared the levels of bacteria after four drying methods cloth towels, paper towels, hand dryer, spontaneous evaporation found no difference in germ levels in any group. A 2012 The Mayo Clinic Proceedings’ systematic review of various studies said that paper towels are superior to air dryers, as friction while using towels help dislodge microrganisms from the skin surface. Dryers, on the other hand could leave bugs behind, and also circulate and dis- perse germs by sucking contaminated air in the absence of proper filters, said the review.
