OK I wasn't expecting this..Costco didn't think they had any problems because the manufacturer puts rice flour in their product. (It is listed as rice flour on the ingredients) so in addition to the other names now you might not want to feed any food with rice "flour" in it. This is actually the same ingredient that others have been listing as rice protein concentrate.
Just when I thought we had all the possible names of suspect ingreients down. sigh
