Debunking the 5-Second Rule

Hey Dave, can you pass me some chips?

Sure...

Thanks... oops, never fails, dropped one.

Too bad the five second rule is just an old wives tale.

I know, yet a lot of people believe it ' that if you pick up food dropped on the floor in under three or five seconds, it's safe to eat. We found a pretty good study showing this is a myth.

In this study, researchers did three experiments.

The first tested how long bacteria could survive on a sterile floor tile. Amazingly, tens of thousands of bacteria were still alive after a month.

In the second experiment, researchers dropped a piece of bologna on three types of contaminated floors: tile, wood and carpet.

As you've probably guessed, a lot of the bacteria on the tile floor got transferred to the bologna and the least amount by the carpet.

The researchers did that experiment several times, but varied when they picked up the bologna. What's surprising is it didn't matter whether they left the bologna for five seconds or sixty seconds, the same amount of bacteria was transferred.

If ten thousand bacteria were transferred to the bologna after five seconds on the tile floor, it was still ten thousand after sixty seconds.

They repeated the experiment with bread instead of bologna and got the same results.

This debunks the myth of the five second rule because within five seconds, bacterial transfer has already occurred.

For tidy people who believe their floors are clean enough to eat on, know that floors also harbor toxic cleaning chemicals and pesticides.

The safest rule is food that lands on the floor should go in the trash.
