In our area, and in most parts of the US, there is a food company named
Schwans that goes house to house(they carry a variety of products).  I
e-mailed them to find out the gf status of their products.  This was the
reply:

When I called, I told the person who answered that my child could not have
wheat, oats, barley, or rye.  She asked me if he had celiac disease, and
told me that they are very concious of whether their foods have gluten in
them.  Although they don't have a published list, they will look up each
item on the computer, and if there has been an inquiry on it, they can tell
you immediately if it is gluten free.  They research the sources of their
vinegar, food starch, and other ingredients. I was extremely pleased with
their knowledge and responsiveness, and wanted to pass it on!
