Understanding Canned Food Expiration Dates: When Is It Safe to Eat?

Many households have forgotten cans of beans, soup, or vegetables hidden in their pantries. When the expiration date passes, the natural reaction is often to throw them out. However, most canned food dates indicate quality rather than safety.

Labels like “Best By” or “Best Before” refer to the peak flavor and texture of the food, not an expiration deadline. Similarly, “Use By” dates mostly appear on perishable items like dairy or meat and denote the period of best quality, not a strict safety cutoff. A can slightly past its date may still be safe to eat.

Proper storage significantly extends the shelf life of canned foods. Keeping cans in a cool, dry place away from sunlight helps maintain food quality and safety over time.

The type of food matters too. High-acid foods such as tomatoes and citrus are best used within 12 to 18 months for optimal taste. Low-acid foods—like beans, corn, and canned meats—can last anywhere from three to five years or longer.

According to USDA guidelines, if a can remains undamaged and sealed, it can be safe indefinitely. Although taste and texture might decline with age, the food inside typically remains safe to consume.

However, there are clear signs of spoilage to watch for. Cans with bulging lids, leaks, rust, deep dents, unpleasant odors, discoloration, or liquid spurting upon opening should be discarded immediately, as these indicate potential bacterial contamination or gas buildup.

Knowing how to interpret canned food dates helps reduce food waste, save money, and make the most of pantry staples. Before tossing a can, inspect it closely—if it looks and smells normal, it may still provide a safe and convenient meal.
