Warning signs your corn on the cob may be spoiled: check immediately!

Corn on the cob is a delicious and versatile summer staple. However, it’s important to be aware of the signs of spoilage to ensure you’re not consuming contaminated corn. If you’re wondering, “Is my corn on the cob bad?”, this comprehensive guide will provide you with all the information you need to make an informed decision.

Signs of Spoiled Corn on the Cob

1. Discoloration

Fresh corn should have bright yellow kernels. If you notice any brown, black, or gray spots, it’s a sign of spoilage. The kernels may also become discolored or mushy.

2. Mold

Mold is a clear indication of spoilage. If you see any white, blue, or green mold on the husks, kernels, or cob, discard the corn immediately.

3. Sour Smell

Fresh corn should have a slightly sweet smell. If you detect a sour, musty, or off-putting odor, it’s a sign that the corn has gone bad.

4. Slimy Texture

The kernels should be firm and slightly crunchy. If they feel slimy or mushy, it’s a sign of microbial growth.

5. Broken or Damaged Husks

The husks protect the corn from pests and contaminants. If the husks are torn, broken, or missing, the corn may be more susceptible to spoilage.

6. Loose Kernels

Fresh corn kernels should be tightly attached to the cob. If they’re falling off or easily detached, it’s a sign of over-ripeness or spoilage.

7. Insect Infestation

Check for any signs of insects, such as holes in the husks or webbing around the kernels. Infested corn is not safe to consume.
