Public Button Hygiene

March 14th, 2010
  • Hello there, Apparently most public buttons (ATM's, lifts etc ...) are covered with traces of urine and feces. I would like to find out: 1) If this is true 2) What other nasties are on public buttons (germs, bacteria etc ...) 3) If (and to what extent) colds, flus and other illnesses can be transmitted by the use of public buttons 4) If, buttons are the worst for this problem in public places (I imagine money and handrails are also bad) Of course any associated infomation would be appreciated. Many Thanks ...


  • Dear mowgly, Very interesting questions - yes, I have heard those dire warnings too. But if one believes them, how are we ever supposed to feel safe going out in public again? Ironically, the more we spray and scrub to eliminate bacteria from our environments, the more we give the "super bug" a chance to thrive. We must remain level-headed and use common sense. The single most important prevention you can do is to get in the habit of washing your hands throughout the day. If you do this, there is little chance that you will become ill from germs in public places. Except for bacteria which may irritate your skin or cause a rash, there is little risk from merely getting some bacteria on your body. The risk comes from transferring the bacteria to your mouth or nose, where it gains entry inside your body. So if you keep your hands clean, I wouldn't worry too much about it. The goal is not to live in a sterile world (we couldn't), but to strike a friendly balance with our environment - moderation in all things, including bugs! Apparently most public buttons (ATM's, lifts etc ...) are covered with traces of urine and feces. 1) If this is true I would say "not most" public buttons are covered with urine and feces. Urine is sterile and causes little threat to your health anyway. Most fecal bacteria is found in public places like washrooms and daycare centers, other areas to a lesser degree. 2) What other nasties are on public buttons (germs, bacteria etc ...) Mold, E-coli bacteria, chlamydia, streptococcus, cryptosporidium, influenza and rhinoviruses, shigella, salmonella, to name some. 3) If (and to what extent) colds, flus and other illnesses can be transmitted by the use of public buttons Colds and flus are transmitted by bodily fluids, sneezing and coughing in particular, because of their airborne abilities. Actually, that is usually how we catch colds. We can go outside on a cold winter's day and never catch a sniffle, but coming in contact with the bacteria or virus is another matter. Let's say someone has a cold and coughs into their hand and then you come along and shake that same hand. No harm will come of this polite exchange unless you then proceed to put your hand to your mouth or rub your nose before you wash your hands. 4) If, buttons are the worst for this problem in public places (I imagine money and handrails are also bad) [I imagine you mean 'which' buttons are worst for this problem] Generally speaking, public areas with water (beaches, pools, washrooms) harbour more of a threat to your health. You need not worry too much about paper money and coins because they are too dry for bacteria to live on. Remember, living organisms need water to thrive. 1. Public pay phone because of proximity to mouths and noses. 2. Public restroom doorknobs, faucets, etc. because there is usually moisture present.
