Unfortunately, your photos did not come through. I am unable to see the damage. It sounds like an insect has pierced the stalks causing damage. I would use insecticides (natural, if you prefer) and fungicides to correct any issues left behind be the insects.

It will, likely, be safe to consume. Less dangerous than the plant, itself.
