Can penicillin be made out of moldy bread?

I do not know the answer to this question. I was on the internet to research the answer myself. I have a 20 year old daughter that was diagnosed with a penicillin allergy when she was 4 years old. She broke out in hives and looked like someone had beat her up. Since then we have been careful to avoid it. The other day she opened a garlic bread package that had been in the pantry and pretty much powdered her face with the green moldy powder, she immediately washed it all off. About an hour later she started breaking out in hives and was very itchy. She did not immediately put it together, and took an over the counter allergy med. It's been about 4 days and she has cleared up, but it left it's scars. We have come to the conclusion that it had to be the bread that caused it. She did not eat or drink anything out of the ordinary, nor did she go anywhere.

I am still going to try to find an answer to this. If anybody out that knows please tell me.
