Storage tips
- Keep canned goods (low acid) sealed and refrigerated after opening to hit the window above.
- Once opened, move it out of the can or packet into a sealed container and refrigerate it. The long window above belongs to the sealed pack, not to what is left in an opened one.
- Decant opened dry goods into airtight containers to keep pests and moisture out.
How can you tell if canned goods (low acid) have gone bad?
- A rancid, paint-like or crayon smell from anything with oil or fat (nuts, oils, whole-grain flours). Rancid fat is the most common failure here.
- Signs of pantry moths or weevils in flours and dry mixes: webbing, clumping or tiny moving specks.
- Off flavors, stale texture or a musty smell.

Shelf-life windows come from the USDA FoodKeeper, published by the USDA Food Safety and Inspection Service (public domain); we vendor the FSIS FoodKeeper dataset and refresh it in place. These are quality estimates, not food-safety determinations or guarantees: actual condition depends on storage and handling, and harmful bacteria may not have obvious signs.
