Fresh vs Spoiled Squash

Fresh squash should feel firm, vibrant, and blemish-free. Spoiled squash shows noticeable changes in texture, smell, and appearance.

Good Squash

Firmness: Squeeze with a light pressure, and it should feel solid and dense.
Skin: Smooth and vibrant with no soft spots or bruises.
Stem: Intact, dry, and not shriveled.
Smell: Mild, fresh, and earthy with no sour or rotten smell.

Bad Squash

Soft spots: mushy or sunken areas.
Wrinkling: Dehydration and age.
Discolouration: Dark or dull patches on skin or flesh.
Mould: White, grey, or black fuzzy spots.
Odour: Sour, fermented, or foul smell.

Specific squash varieties and their spoilage signs

Different squash types spoil in various ways. This happens because of their skin thickness and how long they last in storage.

Summer Squash (Zucchini, Yellow Squash)

Shelf life: 5–7 days in the fridge.
Spoilage signs: watery texture, sliminess, wrinkled skin.

Winter Squash (Butternut, Acorn, Spaghetti)

Shelf life: 1–3 months in a cool, dry pantry.
Spoilage signs: hard skin turning soft, visible mold around the stem, musty smell.

Storage Tips to Keep Squash Fresh

Proper storage is key to extending the life of your squash.

For Summer Squash

Store unwashed in a perforated plastic bag.
Store in the crisper drawer of your fridge.
Avoid airtight containers to prevent moisture buildup.

Store winter squash in a cool, dark, dry place (50–55°F).

Keep away from direct sunlight and damp areas.
Once cut, wrap tightly in plastic wrap or an airtight container and refrigerate.

How to Handle Cut or Cooked Squash

Cut squash: Refrigerate in an airtight container and consume within 4–5 days.
Cooked squash: Store in airtight containers; lasts 3–4 days in the fridge or up to 10 months when frozen.
Freezing tips: Peel, cube and blanch squash before freezing for best results.

Food Safety Concerns

Bad squash is not just yucky—it’s harmful. Squash that develops a bitter taste may contain toxic compounds called cucurbitacins. These can cause stomach pain, vomiting and diarrhea. If squash tastes unusually bitter it should be discarded immediately.
