Lead Bullet Fragments in Venison from Rifle-Killed Deer: Potential for Human Dietary Exposure
This article presents findings showing that 10 million hunters, their families, and low-income beneficiaries of venison donations face exposure risk to lead from venison killed with standard lead-based rifle bullets. This study used pigs to test the effect of lead content in blood when fed fragment-containing venison. The authors also note that subsistence hunter populations have been found to have higher concentrations of lead in their blood than average, as well as studies showing evidence of health problems associated with human lead body burdens once considered safe.
