Storing Canned Food
Canned food should be kept dry and cool, but it should not be subjected to freezing.
Dampness may corrode tin cans and metal lids of glass jars and eventually cause leakage.
Warmth may cause canned food to lose quality. Hot pipes behind a wall sometimes make a shelf or closet too warm for storing food.
Freezing may crack a jar or break a seal and let in bacteria that will cause spoilage. If it does not damage jar or seal, freezing will not make food unsafe to eat. To give food in an unheated place some protection from freezing, cover containers with a blanket or wrap them in paper.
