The places that should be cleaned often, but aren't, include:
- Water fountains. They can harbor as many as 2.7 million bacteria per square inch on the spigot --
and, apparently, the water in them isn't always clean either. - Manual pencil sharpeners. Most classrooms still have them -- and most kids don't wash their hands before or after using them.
- Computer keyboards and mice. These frequently used tools can have 200 times as muchbacteria on them as a toilet seat.
- Sink faucet handles. The thing that most people touch right before they wash their hands.
- Tabletops, like classroom desks and the tables in school cafeterias. According to Dr. Charles Gerba, a University of Arizona microbiologist whose work has earned him the nickname "Dr. Germ," the average desk harbors 400 times more bacteria than the average toilet seat.
