My allergen set is way different than yours, but I did want to mention that I did have a reaction (really scary ana episode) after eating a target brand product - a risotto box mix. It read safe for my allergen set. Was never able to determine if it was cross contamination or a new allergy. (possibly saffron - I just avoid it, which isn't too hard)
Again, probably not that helpful to you, since I'm not nut-allergic, but wanted to chime in with my experience. I do avoid all of the rice/pasta mixes from target now, but I do eat other target brand products that have worked for me.
