HOLLYWOOD, Md. — If you follow the five second rule when it comes to dropping food, you may want to consider the latest research involving the popular saying.
Researchers at Rutgers University in New Jersey say in a new study that bacteria can contaminate food that falls on the floor instantaneously. The findings were published this month in the American Society for Microbiology‘s journal.
“The five-second rule is a significant oversimplification of what actually happens when bacteria transfer from a surface to food,” said Donald Schaffner, researcher.
Schaffner’s research isn’t the first to conclude that as favorite excuse for why that yummy snack that fell on the ground is still good to eat is wrong. The research did find that longer contact time means more bacterial transfer, but that the type of food and surface is just as, or more, important.
