Corn on the cob is a summer staple, but it’s important to know how to identify when it’s past its prime. Spoiled corn can be dangerous to eat, so it’s crucial to be able to recognize the signs of spoilage.
Signs of Spoiled Corn on the Cob
1. Discolored Husks
Fresh corn on the cob has tightly wrapped husks that are bright green and slightly damp. As corn ages, the husks will start to turn brown and dry out. If the husks are completely brown and brittle, it’s a sign that the corn is old and likely spoiled.
2. Mushy Kernels
Good corn kernels should be plump and firm. If the kernels are mushy or soft, it’s a sign that the corn is starting to rot. Avoid eating corn with mushy kernels, as it can contain harmful bacteria.
3. Mold
Mold is a sure sign that corn is spoiled. Mold can appear on the husks, kernels, or even the cob itself. If you see any mold, discard the corn immediately.
4. Sour Smell
Fresh corn has a slightly sweet smell. If the corn you’re buying has a sour or unpleasant odor, it’s a sign that it’s spoiled. Don’t eat corn that smells bad.
5. Slimy Cob
The cob of fresh corn should be dry and slightly fibrous. If the cob is slimy or sticky, it’s a sign that the corn is spoiled.
6. Discolored Silks
The silks on fresh corn are usually a pale yellow or white color. As corn ages, the silks will start to turn brown and dry out. If the silks are completely brown or black, it’s a sign that the corn is old and likely spoiled.
