Exact references cover 0 of 7 detected claims in the English guide. The remaining statements have not completed exact-source review. References alone do not confirm every claim; normal smell or appearance does not prove safety.
Unopened canned goods last years in a cool, dry pantry if the can is intact. After opening, transfer to a sealed container and refrigerate — most opened canned foods last 3–4 days.
Quick decision rule
- If the unopened can is intact, treat the printed date mainly as a quality marker and inspect the can before opening.
- If the can is bulging, leaking, rusted through, or deeply dented on a seam, discard it before tasting.
- Once opened, use the linked food page when it lists a more specific opened or refrigerated window.
Unopened cans
- Store below 85°F; avoid damp basements that rust cans.
- Discard bulging, leaking, or deeply dented cans — botulism risk.
- “Best by” dates are quality, not safety, for most canned goods.
After opening
Never store food in the open can — metallic taste and quality loss. Transfer to glass or plastic, refrigerate, and use within 3–4 days unless the food page says otherwise.
