Signs mushrooms have gone bad

- Mould, dark patches, or an unpleasant smell.
- Heavy wilting, shrivelling, or sprouting.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store mushrooms
Most vegetables keep best in the fridge crisper drawer; a few (potatoes, onions, garlic) prefer a cool, dark, dry pantry — never the fridge. Don't wash produce until you're ready to use it, since extra moisture speeds up spoilage. Many vegetables freeze well after blanching.
