Hand dryers can spread poo particles to your recently-washed hands

Restroom Hand Dryers Suck Up Feces Particles and Spray Them All Over Your Hands

"Within a large building, potentially pathogenic bacteria including bacterial spores may travel between rooms, and subsequent bacterial/spore deposition by hand dryers is a possible mechanism for spread of infectious bacteria including spores of potential pathogens if present", the study said.

The plates were then tested and found to contain 18 to 60 colonies of bacteria each, although harmless laboratory bacteria were used for the test. The results were published recently in the journal Applied and Environmental Microbiology.

A new study conducted by researchers in the University of CT showed that hand dryers expel a lot of harmful bacteria back onto your hands.

Another might be because they don't want to use toilet roll to dry themselves because that's disgusting.

The scientists also explored the effectiveness of using high-efficiency particulate air filters with the hand dryers.

Scientists studied three different bathrooms in the University of CT by placing special plates beneath the dryers for 30 seconds. How many bacteria in the apparatus that the researchers suggest to wipe his hands with a towel, reports the Chronicle.info with reference to the news of Yu. This is then dried and sprays on the hands of the user finds that study. They showed growth of just one or less bacterial colony. Convection created by a hand dryer's air streams, for example, might pull in unfiltered bathroom air.

Researchers at the University of Connecticut School of Medicine found the dryers may suck in bacteria from flushing toilets and spread it onto your hands. But this study showed that adding the filters did not help.
