Old Trunks didn't know this rule until moving to Fargo. It must have been practiced by Tom's family...........
There’s an old wives tale out there called the five-second rule. The old wives tale says that food remains edible if it’s been on the ground for just five seconds or less. Unfortunately, this is not true; well, if you don’t want to risk getting sick that is! The fact is, if there are bacteria on the floor that the food drops on, it doesn’t matter if the food is there for five seconds, ten seconds, or two seconds, your food will contain potentially hazardous bacteria.
Does your floor contain bacteria? Probably. It doesn’t matter how well you clean your floor, it’s likely that your floor contains bacteria. It’s worth noting that the moister the food is that you drop on the floor the more bacteria it will pick up. Should you eat the food off the floor? Probably not, but the five second rule will continue to live on. And, more likely than not, no one will be worse for the wear.
But.................Mother's floors were so clean you could eat off them!!!
