All Quaker Oats rice cakes are run on the same lines as other Quaker Oats
products and are therefore " contaminated" with gluten.. I learned this on
the Celiac List.
The Celiac Sprue Asso. puts out a shopping guide listing gluten-free
commercial products and the following companies have glute-free rice cakes:

     Hain: Plain, and flavored
      Apple cinnamon         Buttered Flavored
      Nacho Cheese            White cheddar
      Apple cinnamon mini   Plain mini
      mini-nacho cheese, chese, ranch plain popcorn,mild cheddar, white
cheddar
      mini munchies- banana split, peach cobbler, choc. mint crunch,
strawberry cheesecake

      Konriko:
        original brown-lightly salted & unsalted
        butter & caramel flavored popcorn cakes

      Lundberg:
         Organic-lightly salted, unsalted, mochi sweet, wild,popcorn
          Premium-brown, mochi, sesame, wild

       Orville Redenbacher's:
          Butter-reg. and mini
           Caramel-reg. and mini
          Mini-apple cinnamon& honey nut

I stay away from all Quaker Oats products as I am very gluten
sensative....hope this helps and if you have more questions be glad to help.
