that has been dropped on the floor is usually OK to eat under the
“five-second rule,” a scientist says. That you can safely eat items that
have fallen onto the ground within five seconds has often been
dismissed as an urban myth. But 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 there only momentarily.
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.
