Corn on the cob is a summer favorite—sweet, juicy, and perfect on the grill or boiled for a quick side dish. But fresh corn doesn’t last long once it’s harvested. If you’ve ever pulled corn from the fridge and wondered, “Is this still good?”, you’re not alone. Here’s how to tell if corn on the cob has gone bad, how long it lasts, and the best ways to keep it fresh longer.
Quick Answer: How Long Does Corn on the Cob Last?
- Fresh (unhusked): 3–5 days in the fridge
- Fresh (husk removed): 1–2 days in the fridge
- Cooked corn: 3–5 days refrigerated
- Frozen corn: 8–12 months when properly stored
Signs That Corn on the Cob Has Gone Bad
Look, smell, and texture are the best indicators of spoilage:
- Smell: Sour or rancid odor instead of fresh, sweet corn smell.
- Husk: Slimy, brown, or moldy husks are a red flag.
- Kernels: Dry, shriveled, mushy, or discolored kernels mean it’s no longer fresh.
- Texture: Sliminess on kernels or cob indicates bacterial growth.
- Mold: White, blue, or black fuzzy patches signal spoilage.

FAQ About Corn Storage
Can you eat corn on the cob past its prime?
If it smells sour, feels slimy, or has mold, throw it out. Otherwise, slightly dried kernels can still be used in soups.
Is it better to store corn with or without the husk?
With the husk on—it keeps the corn moist and slows spoilage.
Can you freeze corn on the cob?
Yes. Blanching first helps preserve flavor and texture for up to a year.
Why does corn spoil so fast?
Corn begins converting its sugars into starch as soon as it’s picked, reducing sweetness and freshness quickly.
Conclusion
Fresh corn on the cob only lasts a few days in the fridge, but knowing the signs of spoilage—sour smell, slimy husks, and mold—helps you avoid bad corn. For longer storage, refrigeration and freezing are key.
To keep your corn fresh, upgrade your storage with Rubbermaid FreshWorks containers or go premium with a Samsung Smart Refrigerator for the ultimate freshness.
