The lead doesn't get into the hams or backstraps.
Almost all of the lead was found in burger. The commercial butchers have enormous grinders, and in their sloppy processing they throw the bloodshot meat right into the grinder, thus getting some lead fragments in there.
Then, they combine the meat from dozens of deer into one huge batch of burger.
So the deer that took a pass through shot in the lungs, and the bullet didn't fragment, and there is absolutely no lead in the meat, is tossed in the giant grinder with some contaminated meat, and the pristine meat gets contaminated also.
Another thing, the initial study by Dr. Cornatzer was done with his son, who was in med school. They got a bunch of packages of meat for the homeless and ran them through an MRI machine.
I doubt that the MRI can discern lead from copper, so a lot of what popped up on the scan was, no doubt copper, not lead.
Dr. Cornatzer may not be aware that bullets are composed of lead and copper.
One of the Yankee states is doing a big study right now that will be informative.
They are taking blood samples from 800 residents. Half are not hunters and eat only store bought meat.
The other half are hunters, or members of hunting families and they eat lots of wild game.
They will test these people and see if one group has higher lead levels.
