I am guessing you are talking about the risk of trchinellosis due to the freeze for 30 days before consumption question. This will probably answer some of your questions...
How can I prevent trichinellosis?
Cook meat products until the juices run clear or to an internal temperature of 170 o F.
Freeze pork less than 6 inches thick for 20 days at 5 o F to kill any worms.
Cook wild game meat thoroughly. Freezing wild game meats, unlike freezing pork products, even for long periods of time, may not effectively kill all worms.
Cook all meat fed to pigs or other wild animals.
Do not allow hogs to eat uncooked carcasses of other animals, including rats, which may be infected with trichinellosis.
Clean meat grinders thoroughly if you prepare your own ground meats.
Curing (salting), drying, smoking, or microwaving meat does not consistently kill infective worms.
I would remove as much fat as possible if I was preping for the freezer.
