Are canned foods safe to eat after exp date?

Generally, canned goods are safe to eat well past their expiration dates as long as the cans remain sealed and undamaged. The expiration dates on canned goods are mostly used as indicators of peak quality and freshness, not safety. The canning process itself, which involves heating food to a high temperature and sealing it in an airtight container, creates an environment that inhibits the growth of bacteria. As a result, the USDA considers commercially canned foods shelf-stable and safe to consume indefinitely if properly stored.

However, it is important to inspect canned goods for signs of spoilage before consuming them, even if they are within the expiration date. Look for dents, rust, bulges, or leaks in the cans, as these can indicate contamination. Do not consume the contents if the can appears damaged or swollen. Additionally, discard any cans that have a foul odor or an off-color appearance.
