In the case of Natural Balance and Royal Canin, it was the company that makes their food that decided to put in rice protein without approval from or informing the pet food company. Royal Canin have now set up a protocol to ensure that they are sent a list of ingredients and their source for each batch of food made.

I'm still feeding Royal Canin, indoor light to 3 cats, Royal Canin SO to 1 cat, and Avoderm to the rest. This is from the Breeder's Choice/Avoderm website:

"4/18/07 - Breeder’s Choice and its family of brands AvoDerm Natural™, Pinnacle®, Active Care®, Advanced Pet Diets®, and Health Food for Dogs® are NOT involved in any recall. We do not use wheat gluten, rice gluten, or rice protein concentrate in any of our dry or canned dog and cat foods. All ingredients in our foods are from certified sources within the United States, with the exception of the Premium New Zealand Lamb and 3 oz. canned cat foods. We have been making high quality natural pet food in our plant for sixty years."

Now that five pig farms and a chicken farm have been isolated for checks because they fed their animals recalled pet foods, the problem is in the human food chain and we should see even more intensive investigations.
