How Safe Is Your Kitchen?
Myth: Open Cans May Contaminate the Contents
Reality: Metal cans are lined so that food can remain stable at room temperature for extended periods. The drawback associated with
keeping food in an open can is that it can't be sealed tightly, which can affect a food's color and taste.
Bottom line: If you have half a can of minestrone left from lunch, pour it into a glass or plastic container that can be properly closed for storage and refrigeration.
