Please, everyone, read the article carefully and don't panic. It does not say that potato starch is dangerous at all. Only one type of potato starch apparently is and all you need to do is contact the company that makes your dog food and ask, like aprilb and mindi's mom did:
Here is a quote taken from the article linked in post #1. I did not put the bolded type in. It is part of the original article:
"The food/treat label will NOT indicate Amflora potato starch/protein. The ONLY way to know if your pet's food or treats contain risky (ok, down right dangerous) amflora potato starch/protein is to ask your pet food/treat manufacturer for a guarantee in writing. Ask them specifically: "Does XXXX (pet product) contain any potato products or protein products that come from amflora potatoes; or any starch with the same properties as amflora?" Get your response in writing! Do not accept a verbal 'yes' or 'no'. If the manufacturer is not willing to put in writing the guarantee amflora potato starch/protein is not used in their pet foods and/or treats, there's your sign.
While 'regular' potato protein sourced from the U.S. or other safe country of origin would not be of concern, Amflora potato protein/starch would be."
