Lead information for hunters

View the DNR's Bullet Fragmentation StudyInformation discovered in spring 2008 indicates that small lead fragments often are present in hunter-harvested venison, particularly ground venison. As a result, the Minnesota DNR conducted the first-of-its-kind lead fragmentation study to simulate how different types of bullets commonly used for deer hunting might fragment.

To date, no illnesses have been linked to consumption of lead particles in hunter-harvested venison. But the DNR recognizes that the potential impacts of lead fragments ingested when eating hunter-harvested game are not well understood. Only now are state and federal health, wildlife and food safety agencies beginning to collect, study and analyze data to determine exactly what those impacts may be.

DNR Fish & Wildlife Division staff designed the study using firearms and ammunition commonly used by Minnesota deer hunters. The results are not exhaustive but they do show that all bullets fragment, some more than others, and make it clear that lead fragments travel much farther than expected.

Hunting is more than a Minnesota tradition. It's part of our heritage. It's part of our families. It's part of our future. Your DNR wants to keep it that way.
