Science Proves the Five Second Rule


According to a new study from Aston University in Birmingham, England five seconds really does make a difference in terms of food safety.

[M]icrobiology professor Anthony Hilton looked at the transfer of E. coli and Staphylococcus aureus (or the bacteria that causes Staph infection) from a variety of indoor floor types (carpet, laminate, and tiled surfaces) to a variety of foods (toast, pasta, cookies, ham, dried fruit, and last but not least a “sticky dessert”).

Each tested round of contact lasted between three and 30 seconds.

It’s not just the precious seconds your meal spends on the ground that matters, though; the type of flooring also plays a pretty big role. For instance, food dropped on carpet is the least likely to pick up bacteria, while food that sits on a hardwood floor for over five seconds is almost guaranteed to pick up something unpleasant

I find this particularly fascinating. Not because of the science – hey, I never doubted the folk wisdom of it. No, I found it fascinating because I always thought it was the three second rule. And I was pretty sure it had to do with zombies. Ergo the t-shirt I had made.

About Heretic

I design video games for a living, write fiction, political theory and poetry for personal amusement, and train regularly in Western European 16th century swordwork. On frequent occasion I have been known to hunt for and explore abandoned graveyards, train tunnels and other interesting places wherever I may find them, but there is absolutely no truth to the rumor that I am preparing to set off a zombie apocalypse. Nothing that will stand up in court, at least. I use paranthesis with distressing frequency, have a deep passion for history, anthropology and sociological theory, and really, really, really hate mayonnaise. But I wash my hands after the writing. Promise.
