Can it sit out?
Bagged popcorn is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if bagged popcorn has gone bad
- Pieces that bend and chew instead of shattering
- A rancid, oily smell off the seasoning
- A stale, flat taste on the first handful
- A greasy bag with the oil gone dark
When in doubt, throw it out.
Damp air is what kills it — a few minutes in a low oven revives limp popcorn, but nothing revives rancid butter flavouring.
