Food that has been dropped on the floor is usually safe to eat under the so-called "five-second rule", a scientist has said.
Germ expert Professor Anthony Hilton, from Aston University, said that although retrieving these morsels can never be completely without risk, there is little to be concerned about if the food is only there momentarily.
Professor Hilton will be demonstrating how the five-second rule works at The Big Bang Fair – a celebration of science, technology, engineering and maths (STEM) for young people – which 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."

So simply breathing for 10 seconds is enough to be contaminated, by that logic ?
Seriously, if you get sick just by eating a fry dropped on the floor for 5 seconds, you should probably have been eliminated by natural selections years ago.
