Keyboards Are Disgusting 526
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.

Air compressors are very helpful, but ultimately you have to get into the nooks and crannies with a Q-tip or something and that is a time-consuming chore. Of course on laptop keyboards, it's way to easy to knock keys loose and depending on how the little plastic apparatus disconnects from the key cap, you can have all kinds of fun attaching the thing again.
I got one of those silicone roll-up keyboards a few years ago. I actually liked using it. Ergonomically, it worked well for me in terms of layout and feel of the keys. The downside is that it stopped working after a couple of months. I haven't tried another, but a keyboard you can simply wash with soap and water is a great thing.

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.

Did the article bother listing precisely what bacteria and fungi they found?

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.

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.

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.
