Food on the floor is just for dogs
CHICAGO -- A young Illinois researcher has debunked the "five-seconds
rule" for food dropped on the floor -- let the dog have it. Jillian Clark,
16, a Chicago high school student, did her summer microbiology internship at
the University of Illinois to see how safe dropped food is. Clarke and her
doctoral candidate mentor took swab samples from floors at dozens of campus
locations, the Newhouse News Agency wrote. Clarke conducted swab tests in the laboratory
on rough and smooth floor tiles inoculated with E. coli bacteria. She dropped
foods, timed them there, then examined them under a high-powered microscope.
Items dropped on infected flooring were indeed contaminated in less than five
seconds. "I think anybody with kids knows that rule," said Lynne
Olver. "Unless you have a dog. Dogs are in there within four
seconds." Olver, a librarian and editor of the Food Timeline, said a
research Web site could not locate the first mention of the five-seconds rule.
