Squash (winter) is shelf-stable at room temperature: cool, dry pantry, or refrigerate at 40°F (4°C) or below to keep it longer. Refrigerating it mainly preserves quality rather than safety.
Look for: Sliminess or a wet film; Mould or dark mushy spots; Limp, shrivelled, or yellowing leaves; An off or sour smell. Never taste something to test it — when in doubt, throw it out.
Yes — USDA FoodKeeper v128 gives about 10–12 months in the freezer at 0°F (−18°C). Frozen food stays safe indefinitely; that window is about quality, not safety.
