What do the symbols in the book mean?
There are some companies that manufacture their products in a dedicated gluten-free facility or environment. Some products also go through strict guidelines and vigorous testing by either the Celiac Sprue Association (CSA) Recognition Seal Program or the Gluten Intolerance Group (GIG) Gluten-Free Certification Organization (GFCO) to be verified as gluten-free. Some companies choose to do private testing for <20ppm gluten, however are not certified by CSA or GFCO.

In our gluten-free guides we have marked these manufacturers and products with the following symbols:
▲ – manufactured in a dedicated gluten-free facility or environment
● – verified, tested, or certified gluten-free by either the CSA
* (star) – private testing for <20 ppm gluten (includes Elisa testing)

There are also some manufacturers that label their gluten-free products as being manufactured in the same facility or on the same equipment with gluten and/or casein and/or soy. In these guides we have labeled those products with the following symbols:
! – manufactured in the same facility as other products containing gluten (GF Guide), and/or casein (GFCF Guide), and/or soy (GFCFSF Guide)
!! – manufactured on the same equipment as other products containing gluten (GF Guide), and/or casein (GFCF Guide), and/or soy (GFCFSF Guide)

For those products that do not contain any symbols, the information about the product testing, facility and equipment was either not disclosed to us or the information could not be found.

Does the Gluten-Free Grocery Shopping Guide include over-the-counter medications?
Yes.

How do you determine that the products in your book are “gluten-free”?
The information is received from product manufacturers and major supermarkets via internet, e-mail, phone, mail, or product labels. The Food and Drug Administration (FDA) has defined the term “gluten-free” as containing less than 20 parts per million (ppm) gluten. Some food manufacturers test their products for the presence of gluten. Those products that have not passed this test have been excluded from our guides. Currently, not all companies test their products, therefore, we cannot guarantee that all the products listed in our guides are less than 20 ppm gluten. Those products that have been manufactured in the same facility or on shared equipment with gluten, but follow strict cross-contamination control guidelines, have been included and are marked with symbols. We have tried our best not to include products from manufacturers that do not take measures to prevent cross-contamination.
