Researchers study three-second rule's validity

Most of us have heard of the three-second rule and many of us are guilty of it, but just how safe is food that you drop on the floor?

Researchers at Britain’s Manchester Metropolitan University found that things like cooked pasta, dried fruit and raw meat don't pass the test. They immediately start collecting bacteria once reaching the floor.

Things like bread and cookies that are dry and high in sugar are generally germ free after about five seconds.
