Researchers from the University of Arizona swabbed shopping cart handles in four states looking for bacterial contamination. Of the 85 carts examined, 72 percent turned out to have a marker for fecal bacteria. http://www.msnbc.msn.com/id/41838546/ns/health-kids_and_parenting/ Just to think all my friends made fun of me for wiping down, with clorox wipes, my shopping cart before putting my DD in the cart. I swear from the day she was born until she quit riding in shopping carts I toted clorox wipes and wiped them down everytime. I worked with the general public and I swear I have seen... 1. Babies gnawing on shopping cart handles. 2. Toddlers walking barefoot in the grocery store as well as wal-mart restrooms. My conclusion, as a teenager , was that the general public is just nasty. This article proves me right. Ewww... just ewww... JMO.
