Thought I'd post for newbies like myself. There are some Wonderbread facilities that are peanut and tree nut free. You have to find the bakery number underneath the Best By date and call the manufacturer to determine if it is from a safe bakery. I'm in the Bay Area, CA and I have been told factory 75 is safe for us. That has been a HUGE help! Now I don't have to bake all my own bread. I will probably still check with them periodically, as manufacturing can change.
