A two-year study from a group of state health departments and the Centers for Disease Control (CDC) shows shopping carts can be a risky ride for babies under 6 months old.
A CDC epidemiologist concludes that infants in shopping carts can become sick when they sit next to packages of meat and poultry and then put the bacteria into their mouths.
That's why one shopper we talked to wipes down her cart.
"To wipe off the bars in the carts and my hands," she said.
But even some health professionals ignore the warnings and don't wipe their carts.
Another shopper said, "I guess I just don't do that. And I'm a nurse. You'd think I would."
The CDC found that juices from meat and poultry can leak, enhancing the bacteria risk for the next infant in the cart.
