After the blood and organs were harvested, you could harvest the bacon and chops too...
In all seriousness... this is an area you'd want to avoid. Even though the bits wouldn't strictly speakign be carved from a human, and thus it wouldn't *exactly* be canibalism... you wouldn't want to give some chimera-bacon to someone, have them say, "Hey! This tastes a little different... but it's *really* *good*! Where can I get more?"
