Sun Flour Baking as of July 2012 is testing cookies with an Elisa at Home Test Kit. All cookies show non-detectable at 5ppm.
Sun Flour Baking states the following regarding the gluten status of their products:
"Do you guarantee that your cookies are Egg, Dairy, Wheat, Gluten, Sugar and Peanut Free?"
Flour products are produced in a 100% vegan dedicated
facility, which means that we DO guarantee that our cookies are
free of ALL animal products. We cannot guarantee that there
won't be trace amounts of wheat, gluten, sugar or peanut because
all of our products are processed on the same equipment.
However, all utensils and machinery are cleaned thoroughly between
each batch, so it is at your discretion whether or not to purchase
Sun Flour products."
