DON'T Double-Dip!

Last week I heard the results of an experiment in double dipping. Prof. Paul L. Dawson of Clemson University wanted to test the conventional wisdom that re-dipping a chip after you’ve bitten some off will spread germs in the community dip. Of course, he had state-of-the-art equipment and plenty of students for his experiment, which found up to 10,000 bacteria CAN be transferred to the dip by each double-dipper. But people who have no such resources do their own experiments every day. :)
