Avoluntary inspection program by the usda is required for all of these animals except

The USDA is not required to inspect the Wild game meat. The meat which is specifically from the cattle, only that is to be inspected and not the other meat.

Explanation:

The United States Department of Agriculture has inspect the meat which is specifically from the cattle. This includes the meat from sheep, swine or goats. It is mandatory for the department of agriculture to inspect these kind of meat and if there is no sign of inspection on these, then it can not be served.

But the meat that the department of agriculture does not have to inspect is the wild game meat. It is not actually considered as meat by the USDA. These are considered as the non amenable and the USDA is not obligated to inspect these kind.
