No guideline: USDA gives no time for that place, usually because the food is not stored that way.

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.

  • Bulging, dented or rusted cans, especially along the seam
  • 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
