ZucchiniShelf Life, Storage, and Spoilage Guide
Pantry
1 week
Store whole, unwashed zucchini in a cool, dark, well-ventilated area. Do not wash until ready to use.
Refrigerator
4-5 days
Store whole, unwashed zucchini in a plastic bag or perforated bag in the crisper drawer. Once cut, store in an airtight container or plastic bag and use within a few days.
Freezer
10-12 months
Zucchini should be blanched before freezing for best quality. Wash, slice or dice, blanch for 3 minutes, cool quickly in ice water, drain, pack into freezer bags or containers, leaving headspace.
Signs of Spoilage
- Soft spots or mushy texture
- Mold growth (fuzzy white, green, or black spots)
- Off-odor (sour or fermented smell)
- Slimy surface
- Discoloration (darkening or yellowing beyond normal)
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
While whole, uncut zucchini can be stored at cool room temperature for a short period, cut zucchini or zucchini left out for extended periods in the danger zone should be discarded.
Safe Handling
Wash hands thoroughly with soap and water before and after handling fresh produce.
Wash zucchini under running water just before eating or preparing. Do not use soap or detergents.
Avoid cross-contamination by keeping zucchini separate from raw meat, poultry, and seafood.
If cooking, ensure it reaches desired tenderness.
