Other interesting points here:

While those that ate meat shot with lead had higher lead levels (higher by a whole 3% of the CDC's "recommended threshold") than those that didn't, the average level for participants in the ND study was 30% LOWER than the national average! And given the fact that nearly half the people tested were 55 or older (older people typically have higher lead levels) and that over 80% of them ate meat shot with lead (also a much higher % than nationally), you might have expected the test group to have a HIGHER lead level than the national average. Came out just the opposite.

Spoke with the Iowa DNR "point man" on the lead issue. The view of the Iowa DNR and Iowa Dept of Health is that the CDC study raises more questions than it answers.
