Does tofu go bad?

Yes. The fridge time above is the window USDA gives for good quality; after it, tofu 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 tofu has gone bad

General signs for vegetarian proteins, the group USDA lists tofu under.

  • Sour or off smell instead of a neutral, mild scent
  • Slimy film developing on the surface of tofu
  • Discoloration, especially yellowing or dark spots
  • Mould, often black or white, on tempeh
  • Packaging that has swollen or lost its seal
