You spill something on the floor, pick it up, and then eat it as you excitedly cry, "Five seconds"!
Well, it turns out doing that isn't horrible. Scientists surveyed 2-thousand people, and found 79% of them admitting to eating food that's fallen on the floor. Science says most of the time, it isn't a problem. Aston University Professor and germ expert Anthony Hilton says eating food off the floor is never totally risk free. Food covered in visible dirt shouldn't be eaten. Duh.
But as long as it's not obviously contaminated, science shows food isn't likely to have picked up any harmful bacteria.
