The 5-Second Rule suggests food is OK to eat if you pick it up five seconds or less. Believe it or not, scientists have tested the rule. We're sorry to report it's not necessarily true. Bacteria can attach （it） to your food instantly, regardless of how quickly it （pick）up. Food left there for five seconds or less will probably collect less bacteria than food sitting there for a longer time, but fast may not be fast enough. Floors, even clean-looking ones, harbor bacteria. Ultimately, if in doubt. abandon the food （avoid） potential illness.
