I’ve heard of the 5-second, 10-second and even 30-second rule. You drop food on the floor and if you pick it up in time, then it’s okay to eat. Is this a safe rule to live by?
For the Love of Bacteria!
One of the most disgusting cases I’ve seen is a pacifier dropped on the New York subway floor. The mom picked it up, stuck it in her own mouth to clean and then right in the baby’s mouth. The pacifier was on the floor for about 5 seconds, but that’s enough time for bacteria to cling to food (or in this case a pacifier).
Bacteria love protein and carb-based foods that are moist and not too acidic. This includes foods like meat, chicken, eggs, dairy, cooked vegetables and cooked pasta. Once bacteria is on a food they love, they can double their number every 20 minutes—this means, one bacterium can become over 1 billion in about 10 hours, which is more than enough to get someone sick.
If you think acidic foods like lemons and tomatoes are safer foods, think again. In 2002, an outbreak of salmonella was reported from participants in the U.S. Transplant Games held at Disney’s Wide World of Sports Complex in Orlando, Florida. The culprit was thought to be Roma tomatoes.
