パソコンのキーボード、トイレより汚い可能性
http://www.iza.ne.jp/news/newsarticle/it/internet/142671/
[キャンベラ ロイター] 英消費者雑誌がロンドン市内の一般的なオフィスにあるコンピューターのキーボードとトイレの便座、トイレのドアの取っ手についての調査を専門家に依頼したところ、驚くような結果が明らかになった。
調査を行った微生物学者は、対象となった33枚のキーボードのうち4つは健康被害を及ぼす可能性があり、その中の1つはふき掃除した便座の5倍不潔なレベルのバクテリアが確認されたとして、オフィスからの撤去を推奨した。
同調査を依頼した「Which? Computing」誌のサラ・キドナー編集長は、「ほとんどの人たちは自分のパソコンに付いた汚れについてさほど気にしていないが、もし掃除していないとすれば、ランチをトイレで食べているのと同じようなものだ」とコメントした。

そういえば、そうなのだ。キーボードは汚い。
まず、汚いことがわからない。ゴミ、髪の毛、お菓子のくずが、キーボードのスキマから中に入ってみえない。
次に、掃除が困難。でこぼこしていて、さらにその奥に掃除ができないエリアが広がっている。
たしかに、これは、汚いはずだ。
気になったので、早速自分のキーボードの掃除をはじめた。
まず、掃除機で吸い取る。オフィスには無いよねぇ。
次に、ウエットティッシュでキーtop,それぞれのキーの四面の横をごしごし。
この時点で、ラーメン汁の乾いたものを多数発見。
その後、空気が勢いよく出てくるダストブロアーで、キーボードの暗黒部分の埃を吹き飛ばし。
一缶500円程度。何かと役立つ。
今後の対策。
・パソコンの前で食べない。
・パソコンの前で食べるときは、キーボードを逆さまにする、あるいは紙かタオルをかぶせる。
・ウエットティッシュを常備して、時々拭き掃除をする。
これをやることにした。
しかし、便所より汚いキーボード、たしかに、ほとんどそうなんだろうなぁ。
How your computer keyboard is FIVE TIMES dirtier than your toilet seat - and could even give you 'qwerty tummy'

Disgusting: In tests, some keyboards were found to have five times as much bacteria as a toilet
Computer keyboards can harbour more harmful bacteria than a lavatory seat, it has been claimed.
Many users are at risk of becoming ill with stomach bugs, according to the consumer group Which?
It warned that 'qwerty tummy', named after the first six letters on a keyboard, could sweep through workplaces after tests on equipment in its own London offices showed alarming results.
One keyboard was so dirty that a microbiologist ordered it to be removed, quarantined and cleaned.
It had 150 times the acceptable limit for bacteria and was five times as filthy as a typical lavatory seat.
Anyone who eats a sandwich or piece of fruit having been tapping on such a keyboard can pick up bacteria that could lead to a stomach upset.
The scientist swabbed 33 keyboards for food poisoning bugs e.coli, coliforms, staphylococcus aureus and enterobacteria and compared the results to those found on a lavatory seat and lavatory door handle.
Four of the keyboards were considered a potential health hazard and one was "condemned".
Two had "warning levels" of staphylococcus aureus and two others had "worryingly elevated" levels of coliforms and enterobacteria, "putting users at high risk of becoming ill from contact".
The expert said the findings were typical of offices all over Britain.
Which? computing editor Sarah Kidner said: "The shocking results revealed that some of these keyboards were harbouring harmful bacteria that could potentially give their users a stomach upset.
"The germs found could cause food poisoning symptoms such as diarrhoea.
"The main cause of a bug-infested keyboard is eating lunch at desks, as the food deposits encourage the growth of millions of bacteria.
"Poor personal hygiene, such as dodging hand washing after going to the lavatory, may also be to blame.
"Most people don't give much thought to the grime that builds up on their PC, but if you don't clean your computer, you might as well eat your lunch off a lavatory seat."
Which? found that one in ten people never clean their keyboard, while 20 per cent never clean their mouse.
Around half cleaned their keyboard less than one a month.
The modern practice of "hotdesking", in which staff sit at different desks every week, means that workers do not know who has been using their keyboard before them.
Miss Kidner said workers and home PC users should give their keyboards a regular clean, adding: "It's quite simple to do and could prevent your computer becoming a health hazard."
Which? says users should unplug computers before wiping surfaces with a damp, soft, lint-free cloth.
Keyboards should be unplugged, turned upside down and shaken.
