Does the 5 second rule really apply

Since one never knows what might be lurking on the floor, the 5 second rule really only applies if you have a microscope and some swabs handy. Even a floor that looks clean can still be contaminated with bacteria or other germs. The second issue is that bacteria might wait to adhere to foods.

Is the 5 second rule true?

– Scientific American Is the 5-Second Rule True? Should you really abide by the famous 5-second rule? Most of us have heard it: if you drop food on the floor, it’s still okay to eat it, as long as you act quickly and pick it up within five seconds of it hitting the ground. But does the so-called “five-second rule” have any scientific backing?

What is the “five second” rule?

The five-second rule implies that if food is picked up quickly after it’s dropped, germs won’t have time to get on board. To find out if that’s true, we start with a hypothesis — a statement that can be tested.

Does anyone have a study of the five second rule?

Yes, someone really has conducted a scientific study of the five-second rule. It was the project of high school senior Jillian Clarke during a six-week internship in the food science and nutrition department at the University of Illinois at Urbana-Champaign.

Is there any truth to the 5-second rule?

The truth about the five-second rule is that you just never know whether you’ve been fast enough. Scientists and germ experts think that the five-second rule does work and that ingesting food that’s spent mere seconds on the floor doesn’t cause serious harm.

Is there a such thing as the 5 second rule?

There ‘s this thing called the ” 5 second rule ” that lots of people have believed for ages. It’s where when food falls on the ground, you have 5 seconds to pick it up and eat it before loads of bacteria actually get to the food and could make you ill. But how true is this theory?

Do You Believe in the 5 second rule?

The new experiments, reported in the journal Applied and Environmental Microbiology, show that the five-second rule is really no rule at all. True, the longer food sat on a bacteria-coated surface, the more bacteria glommed onto it-but plenty of bacteria was picked up as soon as the tasty edibles hit the ground.

What does science say about the five-second rule?

There have been a few scientific studies into the five-second rule. They’ve basically found two things: 1) If you drop food onto a surface that you’ve intentionally contaminated with bacteria, it’s going to pick up bacteria immediately. 2) But most surfaces have surprisingly little harmful bacteria.
