The five-second rule is a popular fiction regarding the eating of various objects that have fallen to the floor or ground. The origin of the rule is unknown. The substance of the rule is that if food falls on the ground, it may be safely eaten as long as it is picked up within five seconds. (wiki)
Found these two cartoons which is funny, demostrating the rule.
Anyway, in case you are wondering, the 5-second rule is NOT TRUE. There is no significant difference in the number of bacteria collected from 2 seconds exposure as there was from 6 seconds exposure. Okay, so today you learnt something!
For me, my rule is that I look at the place it has fallen on and what food it is (see whether it's a yummy one anot. hahaha).
If it's a dry food, for example, cracker, and dropped on my house floor, I'll pick it up.
I'll pick it up if it landed on my dress.
I'll pick it up if it landed on a clean table (home, restaurant, but not food court tables)
I wont pick up food from foodcourt/hawkercentre/public area floor. Cos common sense, many shoes have already stepped all over the place since morning.
I won't pick it up if it landed on the carpet because I feel that carpets are dusty.
If it's a piece of curry chicken, I'd deem it as easier to get bacteria since it's wet, so I wont take it up no matter where it landed on.
What about you? What's your yardstick on when to pick up and when not to?
