Cast your mind back to Sunday, when you crowded around the television with your best buds to watch a great game of football. Now cast your mind back to the eating habits of your friends. Were there any double dippers in your crew? If so, you might be interested in a new study by Clemson University researchers that suggests that double dipping can transfer as much as 10,000 bacteria from the offending eaters mouth to the otherwise innocent dip (and, if you imbibe, your mouth!)
For the study, which will be published later this year in the Journal of Food Safety, researchers instructed nine student volunteers to take a bite of a cracker and then re-dip the remaining portion for three seconds into a tablespoon of test dip. Test dips included sterile water with three different degrees of acidity (appetizing, huh?), a commercial salsa, a cheese dip, and chocolate syrup. The students were instructed to repeat the process with new crackers until they had conducted either three or six double dips per dip sample.
