I thought I read somewhere that DiGiorno's is made in a peanut free (maybe nut-free) facility. Does that sounds familiar to anyone? I don't even see allergen info on their site...
I don't know about a peanut free plant, but I know that digiorno is owned by Nestlé, so I would treat their labeling as I would any Nestlé label.
We used to consider it safe. We haven't had it in several years--because we haven't been buying frozen pizza.
I'm sorry--I don't think that was very clear. Do call them, but I have considered DiGiorno safe in the past. We've been trying to save money. :)
