Champion Petfoods | ACANA | Our Focus is Fresh in the descriptions of the fish they clearly state that the
Salmon, Flounder, and Herring are delivered fresh never frozen and w/o preservatives.
But the walleye, whitefish, and pike
do not say they are delivered fresh w/o preservatives.
When I hear back from Acana I will post what they have to say about this.
FYI: The Acana Pacifica, we can safely conclude that it DOES NOT contain ethoxyquin because it contains only salmon, flounder, and herring.
