I just contacted them since my son refused to eat the bag that I purchased. To him Synder's = unsafe. Here is their response:
"Yes, our Pretzel Poppers are currently produced in a facility that is peanut and tree nut and peanut butter free.
The date code on the front of the package would have the 2 letters ZZ at the beginning of the 2nd line within the code information, confirming this is our peanut, tree and peanut butter free facility.
Hope this helps."
Maybe they will begin to manufacture more in this facility.
