The Grocery Cart
You won't like hearing this one, but it's obvious. According to a 2007 University of Arizona study, nearly two-thirds of shopping carts tested were contaminated with fecal bacteria. That's 'poop' for the lay person. Here's the kicker. They actually found more poop bacteria on the carts than in the average public bathroom. That's just wrong.
Battle Plan: Fortunately many stores are hip to this study, and offer disinfectant wipes right by their cart pickup. Use them. Or, carry some wipes in your purse. And, go the extra mile and bag unpackaged items, like fruits and vegetables, before placing them in your 2/3 infected cart. And, do we even need to mention skipping the free hand-to-germ-to-mouth food samples?
