Kinda gross, right? Food microbiologist Paul L. Dawson cautions, “Before you have some dip at a party, look around and ask yourself, would I be willing to kiss everyone here? Because you don’t know who might be double dipping, and those who do are sharing their saliva with you.”

Dawson was part of a study concluding that the little dab of dip on your chip transfers at least 50 to 100 bacteria from one mouth to another with every yummy bite. Ooh, now that’s delicious.
