Question: I have some leftover canned chicken broth. Is it ok to store the leftovers in the can?
Answer: From a safety standpoint, the answer is yes. The it's safe to refrigerate canned foods manufactured in the United States directly in the can.
That said, the USDA still doesn't advise it. The reason is that canned foods will better retain their flavor and appearance if you transfer them to glass or plastic storage containers after opening.
As detailed here, you may store the opened chicken broth in the refrigerator for 4 to 5 days, or freeze it for longer-term storage.
