Truth Revealed: 5-Second Rule on Dropped Food on the Floor Now Backed by Science


Remember the silly rules we created as children? I can’t remember all of them but this one has definitely stayed with me through the years.

Well good news! Germ expert Professor Anthony Hilton from Aston University has stated that the urban myth may well be true. Although food dropped on the floor cannot be completely without risk, there is little to be concerned about if the food has been there momentarily.

Professor Hilton will be demonstrating the 5-second rule and how it works at The Big Bang Fair – a celebration of science, technology, engineering and maths (STEM) for young people. The fair opens on Wednesday at the NEC in Birmingham.

He said, “Eating food that has spent a few moments on the floor can never be entirely risk-free.”

“Obviously, food covered in visible dirt shouldn’t be eaten, but as long as it’s not obviously contaminated, the science shows that food is unlikely to have picked up harmful bacteria from a few seconds spent on an indoor floor.”

“That is not to say that germs can’t transfer from the floor to the food.”

“Our research has shown that the nature of the floor surface, the type of food dropped on the floor and the length of time it spends on the floor can all have an impact on the number that can transfer.”

Of a survey including 2,000 respondents, 79% admitted to eating food that has fallen on the floor.

Paul Jackson, chief executive of EngineeringUK, organisers of The Big Bang Fair, said: “This is a simple example of how science is present in everyday life.”

“From testing how safe food is to inventing new food and drink, the limits of how we can apply science and engineering are endless.”

Well, kids do say the smartest things, don’t they? Eat on, just make sure that you count 1 through 5.
