Signs of Spoiled Sweet Corn
Recognizing the telltale signs of spoiled sweet corn is crucial to avoid consuming contaminated food. Here are some indicators to look out for:
- Discoloration: Fresh sweet corn should have bright yellow kernels. If the kernels turn brown or black, it’s a sign of spoilage.
- Mold: Any visible mold growth on the corn, whether on the kernels or the husks, is a clear indication of spoilage.
