Strictly speaking, one should aim for high-quality raw meat since they contain higher, better nutrients. So grassfed raw meats are better, raw wild game/raw wildcaught seafood is best of all. AV said to avoid the raw organs from factory-farmed raw meats. Otherwise fine. Prefrozen meat is less worse but better than cooked, factory-farmed raw meats. You might get parasites(highly, highly unlikely) but there are many drugs which easily kill parasites.
