How to tell if oregano is bad

Mould

Any fuzzy growth — discard the bag.

Oregano past the expiration date

Best-by and sell-by

FoodKeeper gives unopened oregano 1–2 weeks in the pantry or 2–3 weeks in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.

Past the date

Oregano past its best-by date is usually safe if stored well; check smell, look and taste before using.

How to keep oregano fresh longer

  • Freeze damage will appear.
  • Store dry, wrapped in a paper towel inside a bag or container.
  • Keep in the crisper drawer at 40°F (4°C) or below.
