Well, to do the topic full justice, please pop on by to my favourite science blogger, Jen Martin from Espresso Science, where she’ll give you the full blown scientific low down in a fun and disgestable format.
This week she explored exactly what science has to say on the popular notion that less than 5 seconds, means thumbs up to the consumption of a dropped item of food. Without giving away too much, I was initially surprised by the finding that although duration was an obvious consideration, both the landing surface type and food type were more important. Dropping a moist piece of watermelon onto a tiled surface is more likely to pick up bacteria when compared with say a dry biscuit on carpet…(carpet? surely not?)
But I have shared enough. Read Jen’s study into the 5 second rule quandary, so that next time you drop food onto the ground, you’ll know exactly what to do.
