I bought fresh green beans a week ago. I had planned to puree them for my baby, but didn't get around to them until today. I stored them inside a mesh cotton bag, in the crisper box in my refrigerator. I took them out today and noticed the beans had brown stripes all over them! I tasted one, and they were still crisp and sweet, although a few had a tougher skin. I was hesitant, but steamed them anyway. The brown stripes seemed to have disappeared in the steaming. But after some quick Googling, I read that green beans with brown spots might have a fungus on them. But... my beans had brown lines, not spots. Is that the same?? Should I throw these beans away? I've already pureed them, and stored them in glass containers in the freezer. But I'm still wary, and wondered if they're safe for my baby? I've posted a pic if anyone would like to see what I'm talking about... Thanks for any input!!
