does have Ethoxyquin in it......If it has fish meal in it......
Risk Ingredients Not Listed on Pet Food Labels
Fish meal suppliers add ethoxyquin prior to ingredient delivery at the pet food manufacturing plant. And guess what? That ethoxyquin added to the fish meal, because it wasn’t added by the pet food manufacturer, is not required to be listed within the ingredients on the label! This is a

Of types of dog food, the “premium” brands of dry dog foods are most often incriminated. However, no correlation of adverse effects with age, gender or breed of dog is apparent.
The reported signs include liver, kidney, thyroid and reproductive dysfunction, teratogenic and carcinogenic effects, allergic reactions and a host of skin and hair abnormalities. There have been anecdotal reports that some of these conditions have resolved after replacement of the ETQ-containing diet with a diet thought to be free of ETQ.
Going by this information I would have to say that if your pets eats this food they are at great risk for the above mentioned effects which would indicate that it is still in a toxic state after processing. The author states her 8 year old dog now has cancer from this ingredient.... I say why risk it....
