Do retort pouches or boxes go bad?
Yes. The fridge time above is the window USDA gives for good quality; after it, retort pouches or boxes may still be safe for a short while but quality drops and spoilage signs start. The date on the package is the maker's quality promise; the times here count from purchase unless marked "from the package date".
Two numbers to keep in mind: a fridge at 40 F (4 C) or below, and no more than 2 hours at room temperature (1 hour above 90 F / 32 C) for anything perishable.
How to tell retort pouches or boxes have gone bad
General signs for meat: shelf stable foods, the group USDA lists retort pouches or boxes under.

- Jerky that has gone soft, sticky or visibly mouldy
- Hissing or spurting liquid when a can is opened
- Off, sour or rancid smell on opening
- Unusual colour change compared to a fresh package
