Can it sit out?
Frozen vegetables is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if frozen vegetables has gone bad
- An ice brick where loose pieces should rattle
- Heavy frost inside the bag and dry, faded patches on the pieces
- A stale, papery smell when the bag opens
When in doubt, throw it out.
Freezer burn is a flavor problem, not a safety one — bury those pieces in a soup rather than serving them as a side.
