Quick answer

Yes. Cooking greens last 1–4 days in the fridge and 10–12 months in the freezer. After that, or sooner if stored badly, they spoil: watch for the signs below.

How to tell if cooking greens are bad

Smell

A sour or rotting smell from the bag or bunch.

Texture

Slimy, wet or wilted leaves that do not perk up in cold water.

Colour

Dark green-black or brown leaves.

Mould

Any fuzzy growth — discard the bag.

Cooking greens past the expiration date

Best-by and sell-by

FoodKeeper gives unopened cooking greens 1–4 days 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

Cooking greens past their best-by date are usually safe if stored well; check smell, look and taste before using.

How to keep cooking greens fresh longer

Store dry, wrapped in a paper towel inside a bag or container.
Keep in the crisper drawer at 40°F (4°C) or below.
Stand herbs like cilantro and parsley in a glass of water in the fridge, loosely covered.
