Is the five second rule actually true?

Food waste is a severe world problem that we should seek to alleviate. According to Wikipedia, wasted food (raw or cooked) costs the U.K. £10.2 billion annually ($ 15.5 billion). The U.S. never even touches 15 percent of what they produce in food, which costs the nation $ 43 billion annually. Considering those staggering numbers, it would make sense that the five second rule of picking dropped food up within the nick of time would be a vestige of the cash conscious. As outlined by Chicago Tribune, a Clemson University study by food scientist Paul Dawson completely rebukes the validity of any such five second rule.

Make the five second rule a zero second rule to be safe, says Dawson

Considering that salmonella and other bacteria can live for up to four weeks on dry surfaces and instantly contaminate food on contact, possibly Dawson is on to something. Previous collegiate studies used apples and Skittles on a college dining room floor. The apple took a minute to become infected, while the Skittles took four minutes more. Another student collegiate study performed at the University of Maine showed the five second rule could reduce food waste and improve child immune systems.

Mind the location, not a time interval

The five second rule is arbitrary and meaningless, claims Dawson and others of similar scholarly bent. If you need to see significant infectious germs, consider bathroom and kitchen surfaces. They’re scary, but other surfaces like sidewalks are usually less so. Amazingly, public sidewalks could be considerably cleaner, as they don’t provide as numerous germ-favorable substances.

Five seconds in your mind

As outlined by the Chicago Tribune, how much a person really wants what they were eating is the real indicator of whether they’ll pick it back up. Thus, sugary snacks tend to be recovered more than vegetables. And get this, food waste aficionados – gender stereotypes wail and die in light of the observed tendency women show to pick up and eat dropped food more than men.
