Beware the double-dipper on Super Bowl Sunday? Or is it just like kissing

In a 1993 episode of the television series, Seinfeld, George Costanza was confronted at a funeral reception by Timmy, his girlfriend’s brother, after dipping the same chip into the dip after taking a bite.

“Did, did you just double dip that chip?” Timmy asks incredulously, later objecting, “That’s like putting your whole mouth right in the dip!” Finally George retorts, “You dip the way you want to dip, I’ll dip the way I want to dip,” and aims another used chip at the bowl. Timmy tries to take it away, and the scene ends as they wrestle for it.

In 2008, food microbiologist Paul L. Dawson at Clemson University oversaw an experiment in which undergraduates found on average, that three-to-six double dips transferred about 10,000 bacteria from the eater’s mouth to the remaining dip.

Each cracker picked up between one and two grams of dip. That means that sporadic double dipping in a cup of dip would transfer at least 50 to 100 bacteria from one mouth to another with every bite.

In anticipation of much dipping during Sunday’s Super Bowl, the Is It True video series af the Wall Street Journal’s Health Blog presents this animation, and concludes it’s not like putting your whole mouth in the dip but could be compared to sharing a kiss with your fellow dippers.
