Is the 5-Second Rule Scientifically Proven?
Is the so-called “Five Second Rule” is real?
Researchers at Rutgers University in New Brunswick, N.J. said that moist or watery foods like watermelon have a much higher risk of collecting germs as soon as they hit the floor.
“You also have a bigger chance of keeping food bacteria-free if you drop it on the carpet,” Shepard Smith said.
“These researchers tested a number of food on a number of surfaces under a number of time intervals,” Kennedy said.
“It is true that the wettest foods, such as watermelons…are the greatest sponge of bacteria. So, you could drop that, pick it up a half-second later and be loaded with the kind of filth that could land you in the hospital for weeks,” she said.
She also noted that bacteria itself is mostly immobile—not traveling around like “puppies looking for dropped morsels.”
“Who wants to eat food that drops on the carpet? No one… eats a piece of buttered toast that’s fallen on the shag rug,” Kennedy said.
