We’ve all seen it happen. You’re at a party and people are gathering around the snacks and someone double dips a chip in the dip. Is it really that bad? According to a study by Clemson University, possibly.
Researchers found that bacterial counts increased significantly after a person dipped a chip, ate it, then dipped the same chip again. Salsa dips had more bacteria compared to chocolate or cheese dips. As a control, they dipped bitten chips into water and found similar bacterial counts.
If a person is already sick, double dipping could spread disease such as the flu or whooping cough. For most people, the risk may not be great to double dip. In fact, sneezing or coughing onto food or not washing your hands poses a much greater risk of becoming ill.
