The point of this product is to serve as a replacement for factory farmed chicken, not the whole chickens you buy at your local farmers market raised in somewhat sustainable conditions, so your point of comparison is moot. If you compare the ingredients of this fake meat to what you find in factory farmed chicken this clearly wins out (no antibiotics or hormones, no cholesterol, higher proetin and carbs, etc).
To counter Botulinum toxins, frozen meat contains Sodium nitrate, a known carcinogen(http://en.wikipedia.org/wiki/Sodium_nitrate#Health_concerns).
