Thanks to howl911.com for the information, and who adds
This finding—melamine in corn gluten—should seal the theory that melamine was added to wheat gluten and rice protein concentrate deliberately .... With this news, Howl 911 believes all pet foods containing additives of any kind from China should be tested for melamine and other contaminates.
This finding also vindicates the claims of many pet parents whose pets were sickened or killed as a result of eating non-Menu Foods brands which did not contain wheat gluten. Virtually all pet foods and many treats contain protein additives in the form of gluten (wheat, corn) or from other grain or vegetable sources (rice, soy, whey), and many of these additives are products of China.
I am sorry to say, but this newest information—combined with the lack of full disclosure from pet food companies as to where they source their raw materials from— renders ALL commercial pet food suspect.
