6 of the Germiest Places in the Supermarket
You're going to want to bring some wipes.
Your Own Bags
Here's one place where you have complete control: your own shopping bags. A small study by the University of Arizona and Loma Linda University (note: funded by the American Chemistry Council, which represents plastic makers), found that almost every reusable bag that consumers were bringing into the store contained large amounts of bacteria (E. Coli was found in 8 percent of the bags). Lai recommends running reusable cloth bags through the normal wash cycle with hot water to kill any dangerous microbes. If your bags are insulated, hand wash or wipe with disinfecting wipes, especially along the seams.
