Certainly is, and that's exactly why I'm steadily moving into a bare-bones approach to my and my dogs' food. I won't feed them kibble any more - and the ready-made treats are on the way out too, and will be completely when I've managed to bake a successful batch of dog biscuits :p - because I feel there's very little way to know exactly what's gone into that food. That, and the volume of uncecessary fillers (such as grains) that my dogs don't need.
The one thing that was the kicker, the thing that finally made me switch them onto raw, was the dilemma with additives - that manufacturers aren't required to declare additives that their suppliers put in the ingredients, if they are aware of them to start with. Having seen a lot of hyped up, podgy dogs being fed terrible foods I have been somewhat put off kibble.
Personally I'm moving towards using only home prepared meals from raw ingredients, in a bid to get away from additives and preservatives in my own food - and I also buy free range meat (with the exception of lamb and beef, though I almost never buy the latter). I'll only buy farmed seafood from decent sources, and that's only because often the species are overfished in the wild (I don't eat cod at all). I also don't have issues with eating the less desirable parts of animals - though rectums and eyelids would perhaps have to be minced :D
