I have to re-think my eating habits now...

A new study by Clorox and San Diego State University reveals the “five   second rule,” which states that if dropped food is picked up off the floor   within five seconds of contact it is still safe to consume, is no longer valid.   Researchers dropped carrots on a countertop, a kitchen sink, a table, carpet   and a tiled floor. They found that germs attached themselves to the carrots   within five seconds of contact with the different surfaces. The countertop was   found to be the dirtiest surface, with the carpeted and tiled floors following   closely in second and third place. 65% of parents use the five second rule in   their homes.
