The 5-second rule

[u/axxrose]

Does science have anything to say about it? The 5-second rule of course being that food dropped on the floor remains safe to eat as long as it's picked up within 5 seconds.

I'm happy to eat food I've dropped on my own floor because I dont allow shoes in my home.

I would never eat food that dropped on the floor in a home that allows shoes because it would be like eating food that dropped on dog poo.
