Five second rule!

Five second rule!
I read with great interest the article on the 5 second rule if food were dropped on the floor. 
 
If you have a clean kitchen floor that is properly mopped two or three times a day, then if food were dropped for up to 5 seconds on the floor it would definetly be safe to eat. Howerver baby's food if dropped would always go in the bin. 
 I have always believed that if raw food should fall on the floor, it was considered good practice to wash the item and continue with the cooking process.  However if the item were cooked and no further cooking was required I would still throw it away, just to be on the safe side.
