It obviously wasn’t the goal, but power outages with the extreme cold weather we faced recently may have allowed canned or jarred food to freeze and become unsafe to consume. Let’s look at some tips to keep those foods safe to eat. If you have canned foods, either home canned or commercially canned, in a storage location that froze, first check for broken seals or seams in metal cans or broken glass in home canned foods due to the expansion of food and liquids inside those containers.
If all the preservation containers are intact, then they can be saved. Thaw the canned food gradually and store it at room temperature. It is recommended to discard commercially canned foods with broken seams or home canned foods with broken glass, as they can lead to contamination. This includes home canned foods that came unsealed and thawed.
