Canning -- Miscellaneous

Are canned foods safe to use after they have been frozen?

Rating: 100

If the seal on jars is not broken, the food is safe to use. If cans do not bulge or have any leaks, they are safe to use. The quality of the product will have decreased if the foods have frozen. To prevent canned foods from freezing when they must be stored in an unheated area, wrap containers in several layers of newspaper and/or drape a blanket over the containers.
