Is your child's packed lunch the right temperature to be safe? Elizabeth Cohen explains new study

A new study in the medical journal Pediatrics has found that 98% of perishable foods in sack lunches are kept at unsafe temperatures even when the food is packed in an insulated lunch box or stored in a hot thermos.

Texas researchers found that on average, kids' packed lunches were approximately 22 degrees warmer than they should be, putting children at risk for foodborne illnesses.

CNN's Elizabeth Cohen discusses the study on American Morning today, explaining what parents can do to ensure that the lunches they pack for their kids stay at safe temperatures throughout the school day.
