There are risks associated with anything you feed; feed soft pliable bones (no weight bearing bones) and feed size appropriate (a turkey neck for an aggressive large breed chewer can be a serious hazard.)
As far as meat (quality), I do feel there’s a difference between organic and non-organic. I also feel there’s a difference between organic and grass fed. However, feeding organic pastured meats can become very expensive; source human-grade, clean meat from reliable sources and you should be just fine.
I have a lot of respect for any vegetarian or vegan who realizes that feeding their diet to a carnivore is not the best idea. Kudos to you, and best of luck!
