Have you ever forgotten a bag of groceries in the car during the winter months when you are unloading your car? If you have you may have wondered about the safety of canned goods that have frozen. The problem that happens in canned goods is that when liquids freeze they expand. If you notice that the cans are swollen, and you are sure the swelling was caused by freezing, the food may still be usable. Put the cans in a container and put them in your refrigerator and let them thaw naturally before opening them. After you open it if there is anything questionable in the look or smell of the food throw it out. DO NOT TASTE IT! If the seams of the can are rusted or burst, throw out the cans immediately.
