I grew green bell peppers and left them on the plant to turn red. I have nothing spicy planted in my garden and the closest neighbor to me that has a garden is atleast a mile away. Most of the red peppers are sweet, but a few have been spicy .....and I don\'t mean jalapeno hot, I mean burn your tongue, eyes, nose and fingernail instantly burn. Just a pea size piece made my husband loose his breath. How could this happen ???

My question to you is this: Did you harvest the seeds from previous peppers, or did you buy the seeds?
If you bought them, then more than likely there is a hot pepper somewhere nearby that is not known about. If they were harvested from previous peppers, then it is a good chance that it was cross pollinated the previous generation. Either way, there is a hot pepper plant somewhere to blame.
