Shelf-stable food storage
How Long Does Shelf-Stable Canned Ham Last?
USDA lists shelf-stable canned ham at 2–5 years unopened and 3–4 days refrigerated after opening.
Official decision table
| Food or condition | Action or period | When it applies |
|---|---|---|
| Unopened | 2–5 years | Shelf |
| After opening | 3–4 days | Refrigerator |
How to make the decision
Shelf-stable only means a product can be kept at room temperature before opening. A Keep Refrigerated label, damaged package, or opened container changes the storage rule.
When a package provides stricter storage or discard instructions, use the package. People at higher risk from foodborne illness should be especially conservative with refrigerated perishables.
What to do now
- Record how long the refrigerator, freezer, or package was outside its intended temperature range.
- Use a food or appliance thermometer when a temperature reading is available.
- Apply the exact row above instead of relying on smell, appearance, or a taste test.
- When the time or temperature is unknown, choose the safer action.
