    With this kernel anomaly, red streaks form on sides of kernels and extend over the crown. Streaked kernels are more common at ear tips, especially if the husks are loose and kernels exposed. Kernel red streak is sometimes attributed to ear molds or mycotoxins.

There is no evidence that consumption of corn exhibiting kernel red streak is harmful.
