The 5-second rule actually makes sense
March 15 , 2014
A professor of microbiology mentioned that the five-second rule may actually have science behind it. Reports suggest it depends on whether the food falls in your kitchen or bedroom.
Two types of bacteria namely, E.coli and Staphylococcus aureus, were looked at when a cookie, toast and pasta were dropped on different surfaces for 3 to 30 seconds. Both flooring type and time played a role when it came to the transfer of bacteria.
The findings revealed that bacteria didn't transfer fast when carpet was involved. "We have found evidence that transfer from indoor flooring surfaces is incredibly poor," the professor said. However, Alice Walton of Forbes stated that the study hasn't been accepted for publication yet.
