They handle the gluten free pizza base with clean equipement only and the pizza then goes into the big, open pizza oven in the carton the base came in. This is to help cross-contamination. There however is only one oven, so non-gluten free pizza has also been in there. But personally for me, probably because the oven is open, I didn't get any symptoms.
