How to avoid cross contamination
Keep ready-to-eat and raw foods separate in your shopping cart.
Drippings from raw meat, poultry, and seafood can contaminate other foods even before you head to the checkout line. Place raw foods in the bottom of your shopping cart as far away from ready-to-eat items as possible.
Never store meat on top of produce or place a bag of veggies directly on top of a package of raw meat. Ready-to-eat foods are items that don't need to be cooked or have already been cooked.
