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. Those are the general signs for grains, beans & pasta — USDA FoodKeeper v128 publishes no spoilage note for Tortillas (corn) specifically. Never taste something to test it — when in doubt, throw it out.
