Does puff pastry go bad?
Yes. The fridge time above is the window USDA gives for good quality; after it, puff pastry 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 puff pastry has gone bad
General signs for baked goods: refrigerated dough, the group USDA lists puff pastry under.
- Container or tube bulging or the seal has popped
- Grey or off-colour patches on the dough surface
- Sour, yeasty or alcohol-like smell instead of a mild one
- Slimy or unusually sticky texture on the outside
- Visible mould spots, often blue-green or white
