It is possible to make it edible but very difficult and rare. If it is drown in something like cheese it is possible, think I had a quiche that had it baked in and that was good. I had a salad that had it in there and that was great.
My mom sent me a link to the article, not realising I was aware of the epidemic, said she bought 3 bags of spinach and ate 2 already and now is paranoid and asking me if she should boil the last bag, I told her it would be a good idea, IL is between IN and WI and this outbreak is scattered all over the place so you never know!
