How long can you keep a dearborn ham in the refrigerator?

A Dearborn ham can typically be kept in the refrigerator for about 3 to 5 days after opening. If it's an unopened, vacuum-sealed ham, it can last up to a week past the expiration date. For longer storage, consider freezing it, which can extend its shelf life for several months. Always check for signs of spoilage before consuming.
