Cumin (ground, dried, commercially bottled or purchased in bulk, opened or unopened) is shelf-stable at room temperature: cool, dry pantry away from heat and light. Refrigerating it mainly preserves quality rather than safety.
Look for: A rancid, paint-like, or musty smell; Bulging, leaking, deeply dented, or rusted cans; Insects or webbing in dry goods; Mould or discoloration. Those are the general signs for pantry staples — USDA FoodKeeper v128 publishes no spoilage note for Cumin (ground, dried, commercially bottled or purchased in bulk, opened or unopened) specifically. Never taste something to test it — when in doubt, throw it out.
