    Recent research shows your keyboard is more dirty than a toilet seat

    (2006-01-18 09:20) Do you have some dirt between the keys on your keyboard? Spending a few bucks on a new keyboard might be a good idea. The latest issue of Pc för Alla shows that a keyboard can be a major source for contamination.

    By Fredrik Agren

    A keyboard holds about 33.000 bacteria per square centimeter - 265 times more than a toilet seat.

    The computer magazine PC För Alla has examined what exactly is hiding on a keyboard. The task was assigned to Pegasus Lab, which discovered that every square centimeter contained 3.100 fungees.

    Not surprisingly, Enter and Space Bar are the most filthy, as they are the keys we use more frequently.

    There are many ways to keep your keyboard clean, but those afraid of catching the flu can follow a simple advice from Smittskyddinstitutets Kerstin Mannerquist:

    - Wash your hands when you're done with the computer, she says to PC För Alla.


    Anyway, remember the findings of Mythbusters []?
    In the episode Chinese Invasion Alarm [] episode, while busting the 5 second rule myth, they discovered that the toilet seat is one of the cleanest spots in your house.

      not surprising. Fungal spores are nearly omni-present in the environment, and bacteria thrive on your skin at all times. Now, given that the keyboard is open to the surrounding air and has plenty of shielded space, yes, spores will accumulate there. But there's a difference between 3,100 fungal spores/sq. cm and having fungus actually growing there. Also, I have to question that number - 3,100 spores is a lot of spores.

      Did the article bother listing precisely what bacteria and fungi they found? I wouldn't be surprised if they mostly found bacterial species from the genera of Bacillus and Staphylococcus with a few gram-negative rods thrown in for good measure. Oh, Propionibacterium acnes is probably pretty common as well. With the fungi it's more of a mixed bag, although most would probably fall into the general category of Ascomycetes.

      As for catching the flu from your keyboard... Viruses such as Influenza don't survive on dry, non-porous surfaces for very long. Once the viral envelope has dried out, the virus is pretty much inactivated. You stand a better chance of catching the flu from talking to the person in the next cubicle or on the elevator.

He meant that the ass is routinely covered during the day thus does not have much of a chance to pick up bacteria before you use the toilet. Therefore, since your ass (think cheeks, not hole) is relatively bacteria free when it touches the toilet seat, the toilet seat doesn't have much of an opportunity to pick up germs.

    It seems to me that this just points out the way overblown hype against bacteria. Hundreds of thousands (millions?) of people use keyboards every single day, and anecdotally, it doesn't seem like people are getting infections or having other issues (other than things like carpal) at a higher rate in the computer age due to the amount of bacteria found on keyboards (and believe me, it isn't because of increased personal hygene). Now if they further extrapolate and say that while most of the current bacteria is harmless, that keyboards represent excellent carriers in the future for more harmful bacteria, well, that's a more interesting story. But then again, doesn't that just say that you should keep your kb as grundgy as possible to keep those "good" bacteria in and the "bad" bacteria out?
    • Well, actually quite a lot of people who use keyboards get sick all the time. There is a ton of evidence that when you get a cold or whatever, then you touch something, and then somebody else touches it, that that is the most common way for colds to spread.

But I guess they can start a new commercial campaign about how we should always wash our hands before and after using the computer...

    Maybe bacteria laden keyboards are a blessing in disguise.

    A few weeks ago I was at a party listening in on some cocktail talk between some doctors and health researchers. They were commenting about how some water borne bacteria was being (they think successfully ) experimented with to boost human immunity. This bacteria is cleaned out water by public sanitation systems.

    A few weeks before that my local news had a piece about a girl with a peanut allergy who died after kissing her boyfriend who had eaten a peanut butter sandwich earlier in the day.

    The after story commentary mentioned how the number of allergies among teens is on the rise and how some ( only some ) experts were looking at the theory that middle class US life is too clean. Antibacterial this and antibacterial that do not allow young immune systems to get stimulated/strengthened.

          Actually, what you state has some scientific backing.

          I heard it on the news last year that some German (?) scientist recommended eating nose mucous. As he stated, the nose is the only organ of the body that for the most part does not have a self-cleaning mechanism. The purpose of the mucous is believed to be (among other things) the entrapment of bacteria and other undesirables that would otherwise have entered the body.

          By picking, we provide the nasal passages with a method of cleaning to provide new mucous and by -- ugh -- eating we introduce the bacteria into our systems that were otherwise trapped, thus allowing our immune systems to learn about it and, more importantly, learn to defeat it.

          I actually discussed this a few days later with a friend of mine who's an Emergency Medical Technician and was a medic in the Army Reserves. After hearing the doctor's explanation, he agreed that it all makes sense. The immune system can't practice its self-defense if it doesn't have any targets to destroy.

    One call had me responding to a guy whose keyboard was, bar none, the most disgusting I've ever seen. He had left for the day, and I picked up the keyboard because he'd left a USB device plugged into it. Something like a metric ton of dander, hair, and bread/cracker/cookie crumbs fell out of it.

    A few weeks later, the building administrator (read: not my boss) sent me a note explaining to me why I needed (read: ordering me) to go to everyone's keyboard, blow out the keys with compressed air, wipe them down, check every key for motility, and wipe down the monitors. After a brief consultation with my boss, I replied that I trusted our employees to be able to handle those maintenance tasks themselves, although I'd be happy to help if there was a specific problem.

    All this is by way of saying: some people just don't think about it, and some people just want it to be someone else's problem. But it's your mess, so clean it up, for chrissake.

    a normal PC keyboard was infected by more bacteria than a normal toilet seat.

    Why are people surprised by findings such as this one?

    Obviously the toilet seat has less germs. Everyone associates "grossness" with germs in their head. Going to the bathroom is gross, and fecal matter is gross, therefore it must be full of germs and bacteria. Not the case, in fact, quite the opposite.

    There are more bacteria on your face, more bacteria on your hands and more bacteria in your mouth than your buttocks in most cases.

    Just put in the context of contact with the germ filled world you can see by common sense why this would be true:

    Your rear end gets washed and then has very little exposure to germs. Your hands and face are out there all day making contact with all types of bacteria.

    So I guess my point is that you can't say keyboards are dirty just because they are more bacteria filled than a toilet seat, because I don't even think a door knob holds up to that standard.

    Now common sense would also side with keyboards being rather bacteria filled, but I hardly would consider that comparison to be an indicator.

    There's always a way to clean your keyboard--the dishwasher.

    Take the electronics and screws out and set them aside. The keys, the base, and the rubber pad are dishwasher washable.

    Use 1/4 to 1/3 of the amount of liquid/power for a full load, and put it on the shortest cycle you can manage and even then keep accelerating the cycle a bit. You want the keyboard clean but not baked.

    Don't put anything ELSE in the dishwasher--you're shortening the cycle so you won't have the power to wash too much. The plastic may be dishwasher safe (seems to be) but you don't want to take any chances with the rubber.

    If you have a white or ivory keyboard, note that it may yellow a bit, so don't do this on a keyboard you don't own unless the person fully trusts you.

    Note: This doesn't work with IBM Model M keyboards (the clicky clicky clack kind) for obvious reasons, but you could probably take the keycovers off and wash those. ;)

    I'm not responsible if you damage your keyboard.
