This is the response I received:
I just wanted to get back in touch with you regarding your question about certification of the Perfectly Simple ZonePerfect bars.
Perfectly Simple bars meet the FDA definition of gluten-free and are compliant with all gluten-free regulations. The bars are made with gluten-free oats.
Equipment, ingredients, and finished product are tested to meet all requirements issued by the Gluten Free Organization (www.gfco.org). Perfectly Simple Bars are tested to meet the FDA standard of less than 20 ppm of gluten (i.e., ~1 mg/50g bar). In addition, Perfectly Simple bars are manufactured on a line that is certified and tested to be designated as gluten free by the Gluten Free Organization (www.gfco.org).
Please let us know if you have any additional questions.
So, anyone try the new Perfectly Simple bars yet? If so, what did you think? I hope to pick some up soon to try them out. I can’t decide which one I want to try – they all sound good!
