Which foods are harmful after expiring, even if they've been refrigerated?

Foods that may harbor Listeria can be harmful after expiring, even if they've been refrigerated. Listeria can grow despite refrigeration. The Food and Drug Administration (FDA) says that illness caused by Listeria can be especially dangerous for at-risk groups, including pregnant women, newborns, older adults and people with weakened immune systems.

So, pay attention to the dates on these foods:

  • deli meats
  • unpasteurized dairy products
  • ready-to-eat refrigerated foods (best to use them as soon as possible)
  • hot dogs and sausages (if they're not fully cooked)
