How long does food in a retort pouch last once opened?
Once a retort pouch or box is cut open it’s fridge food with 3–4 days on it — USDA carries no unopened pantry window here, so go by the package date until you open it.

Can it sit out?
Unopened, an opened retort pouch is shelf-stable. Once opened, treat it as 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 an opened retort pouch has gone bad
- A puffed or swollen pouch — don’t open it, bin it
- A pinhole, split seam, or any leak in the packaging
- A sour or fermented smell when the seal is cut
- Contents gone cloudy, foamy, or an odd color
When in doubt, throw it out.
Tip the contents into a covered container once it’s open — a pouch won’t reseal, and it isn’t a fridge tub.
