Each sense will offer valuable clues in determining whether your corn on the cob is fresh or if it’s headed for the compost heap. So, let’s get down to the specifics.


When assessing your corn’s freshness, pay close attention to the color and sheen of the kernels. They should exude a vibrant and shiny look, signifying they’re at their peak.

Essentially, if your corn doesn’t smell quite right, it’s best to steer clear. Rely on your nose—it’s a reliable ally in ensuring food safety.


Engaging your sense of touch can tell you a lot about your corn’s condition. Fresh corn will have kernels that are firm to the touch and nicely plump—a clear indicator of good quality.
