So, I too recently stumbled upon this new pizza, and have it in the oven now (the 4 cheese gluten free pizza). As I read the box for what temperature to put the oven on, I noticed the wheat warning and decided to do a little research. This is what Sarafina has posted on their facebook page as of last week.
"For those concerned with a Warning Statement on our Gluten Free packaging that: "Products are produced in a facility where wheat products are used." There is no need to be concerned. Our pizza's are made in a Gluten Free Certified Facility. The plant is heavily tested and inspected from Cdn Food and Agriculture. If we didnt meet the standards we would not be allowed to produce the products. However, because wheat products are made in this facility it is by law that the statement be included. We have sold thousands of pizza's to date without a single issue. So please enjoy without any worries. Buon Appetito!"
As a response to a comment, they state "Our products are below 5ppm."
I am willing to give it a try, I'll let you know how I make out!
