About 1–2 weeks in the pantry, according to USDA FoodKeeper v128.
Toaster pastries are shelf-stable at room temperature: cool, dry pantry, sealed — refrigerating after opening is optional and mainly preserves quality. 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 Toaster pastries specifically. Never taste something to test it — when in doubt, throw it out.
