A recent study from Aston University in England verified that it is still safe to eat food five seconds after it fell on the floor.
Popularly known as the “five-second rule,” this common belief has long been a subject of argument among scientists. Researchers from Aston decided to end this debate with a conclusion that this particular belief is true.
In 2007, Clemson University from the United States also tested the legitimacy of the “five-second rule”. Aston and Clemson used similar methods for the study, found the same results, but had opposite conclusions. Researchers from Clemson University argue that eating dropped food can never be safe.
Both studies analyzed how fast bacteria contaminate food on the floor. Three different types of floor surfaces were used to assess bacteria’s reaction – tile, wood, and carpet. Aston researchers used E. coli [EE KOH-lahy] and Staphylococcus aureus [staf-uh-l uh-KOK-uh s AWR-ee-uh s] while Clemson used Salmonella [sal-muh-NEL-uh]. Aston tested various foods with dry and moist qualities while Clemson just used bologna [buh-LOH-nee] and bread.
Results showed that the bacteria’s transfer rate was fast for both experiments. Both studies concurred that food on carpeted floor had lower bacteria transfer rate than tiled and wooden floor. However, Aston University particularly discovered that dry food gets fewer bacteria than the moist ones.
According to Anthony Hilton, leader of the Aston study, the low transfer efficacy of bacteria to food supports the conventional five-second rule. The amount of bacteria transferred within five seconds is too scant to cause any harm.
However, Paul Dawson [DAW-suh n], head of Clemson study, disagreed with Hilton’s belief. Dawson said the presence of bad bacteria in food is enough to ail someone.
