Here are the two key quotes from the North Dakota study, in which blood was analyzed from 736 volunteer participants (80% of whom consumed wild game):

"Participants who consumed wild game had . . . higher blood lead levels in comparison with those who did not consume wild game."

"While this study suggests that consumption of wild game can adversely affect blood lead levels, no participant had a blood lead level higher than the CDC recommended threshold, the level at which CDC recommends case management; and the geometric mean blood lead level among this study population was lower than the overall population geometric mean blood lead level in the United States."
