A worm in an ear of corn means you can’t eat it

The corn, not the worm! The corn earworm, Helioverpa zea, is the larva, or caterpillar, of a moth. There is almost always one per ear, and they inhabit the tip of the ear, feeding on the kernels. I have seen a lot of people at the local farmers’ market rejecting ears of otherwise excellent corn because there’s a worm. What a waste! Organic corn often has a worm, because spraying with toxic insecticides is the only way to prevent them. All you need to do is cut off the tip of the ear, removing the worm and the damaged kernels, and you’ll be fine. I’d much rather eat an ear of corn that had a worm removed than one soaked with insecticides.

    Absolutely! We grew tons (literally) of sweet corn where I grew up, and virtually every ear I ever ate had it’s own worm or two at one point. The non-eaten corn was still delicious.

    “Soaked” with insecticides is a bit of a stretch, but good to know I can cut the tip off my conventional garden corn that had a worm on it. Planting Bt sweet corn next year to avoid this problem.

    I heard that the corn worms are edible too, is this true?
