Last year I made pickles and in one jar the garlic turned blue-green. I consulted with someone who is a food health expert, and she said it happens, and is related to soil the garlic was grown in. Not to worry- eat it. I did, it was fine.
Now, for your problem... do not feed it to your dog... feed it to your neighbors dog....
I would guess your situation is related to your peppers.
