It’s highly unlikely that you haven’t heard about the “five-second rule” – that if you drop something on the ground and pick it up less than 5 seconds after, it would still be edible. And while this “rule” has been considered as a pure myth for many years, a group of scientists have proved the rule is actually true.
Professor of Microbiology Anthony Hilton and his team of undergrads from the Aston University in Birmingham, UK, have studied the so called “rule”. By conducting a number of tests with common bacteria, including Escherichia coli (also known as E. coli), and various sticky foods like pasta the team managed to amaze the whole world. The results showed that common bacteria were indeed in need of enough time to stick on the food and five seconds were somewhat not long enough. Nevertheless, the results still showed that bacteria can contaminate the food even under five seconds.
The team also studied the difference various floorings had on the tests. It turned out that the carpeting was the safest flooring when it came to indoor bacteria contamination.
