| Situation | Keeps for |
|---|---|

| Unopened · fridge | 60–90 days |
About 60–90 days at 40°F (4°C) or below, according to USDA FoodKeeper v128. That window runs from the day you bought it — FoodKeeper publishes no separate after-opening figure for this one.
Tortillas (corn) are shelf-stable at room temperature: cool, dry pantry, or refrigerate at 40°F (4°C) or below to keep it longer. Refrigerating it mainly preserves quality rather than safety.
Look for: A rancid or musty smell; Insects, webbing, or larvae in the package; Clumping or visible moisture; Mould, or a slimy surface on cooked grains and pasta. Never taste something to test it — when in doubt, throw it out.
