How long can canned food be stored safely?

Calculating Shelf Life

Canned food manufacturers provide a “best by” date, but this is not the same as a “use by” date. Shelf life is determined by the manufacturer’s quality control measures and the storage conditions. Generally, canned goods stored in a cool, dry place can last 2 to 5 years. However, if stored in extreme temperatures (above 80°F or below 40°F), shelf life may be reduced to 1 year or less.

Storage Conditions

To extend shelf life, store canned goods in a cool, dry place away from direct sunlight and moisture. Avoid storing canned goods in attics, basements, or areas prone to flooding. If you live in an area with high humidity, consider using a dehumidifier to maintain a relative humidity of 50-60%.

Family Size and Storage Quantity

When calculating how much food to store for your family size, consider the following: assume 1 pound of canned food per person per day for a 3-day supply, and 1/2 pound per person per day for a 5-day supply. For a family of four, a 3-day supply would require approximately 16 pounds of canned food, while a 5-day supply would require approximately 8 pounds. Adjust quantities based on your family’s needs and the shelf life of the canned goods.
