Double Dipping Demonstrably Disgusting

According to a report detailed by the Times, double-dipping your chip back into the dip does indeed send your menagerie of mouth monsters back into the French onion slop. Don’t do it.

On average, the students found 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.
