You probably do it sometimes:dip your chips in the sauce again after you've already taken a bite... How dirty is that anyway?
During the study, three dip combinations were tested:chips with cheese, chips with salsa, and fruit with chocolate. The dips did not contain any bacteria at the start of the study.

Then a group of people started dipping. They did double-dipping:after taking a bite, they dipped again. The number of bacteria was measured again. 1,000 bacteria were found in the salsa. Against 200 in the cheese and 158 in the chocolate. Better news:after two hours the number of bacteria, especially in the salsa, had decreased considerably.
Something to think about…
