Keyboards Are Disgusting
fredr1k writes "
A test carried out by Pegasus Lab on account for Swedish magazine PC För alla showed that a normal PC keyboard was infected by more bacteria than a normal toilet seat. More specific it contained 33000 bacteria per square centimeter, compared to 130 on a ordinary toilet seat. The tests also showed occurrence of up to 3100 fungi per square centimeter." Also note that unless you read Swedish, you still have plausible deniability when asked to windex yours.
Just wait until everyone puts spittle everywhere from talking to computers.
Laws are for people with no friends.
There was a Myth Busters episode testing the '5 second rule'. They found the same oddity, the toilet seat was the cleanest place (according to bacteria counts) in the whole shop.

There should be enough epidemiologic data that we don't have to rely on bogus measures like "number of germs" to try to estimate the risk of catching something from a keyboard. I suspect it is minimal.
I have a bottle of cleaning fluid that that purports to kill 99.something% of bacteria. Does that make me safer? Probably not; instead I'm helping the natural selection process to breed super-bugs that are resistant to antiseptic.
The specious "germ" argument is exactly the same as the one used to compute risk of intrusion by the number of reported exposures in a software system. What matters is infection/intrusion, not exposure. And it *can* be measured, so why bother to measure the bogus quantities?
toilet seats are cleaner the most other surfaces in a house
and in an office (desk, phone, etc). This was a very diggsian story in that it repeats 10-20 year old information as if it were brand new. The mystery isn't that everything else is so dirty, it's that toilet seats are so clean! And would the results be different if they tested the average Slashdotter's toilet that only gets cleaned twice a year?
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.
We *need* this exposure. I'm worried for children growing up in sterilized environments today.
Pretty good article on the subject. The theory being a clean environment leads to an overactive immune system that can develop into severe allergies.
Otherwise, I don't worry: These are _my_ germs, mostly things on my hands that I've already built up an immunity to or have no way of avoiding even if my kbd was sterile. I won't let others use my kbd, and I really try to avoid using others kbds. A much bigger problem is money and door handles. Lots of people touch them and I could get some new virus/bacterium.
BTW: toilet set tops are often very clean. But less so the undersides where women want men to put their fingers to raise and lower toilet seats! Default=up might be more sanitary.
