Lead Ammunition, Wildlife Poisoning, and Public Health: Science and Policy at a Crossroads | Episode 87

In this episode of the Animal Wellness Podcast, host Joseph Grove examines the mounting scientific and policy concerns surrounding lead ammunition — a persistent environmental toxin with consequences that extend far beyond the hunt.

Each year, tons of lead from spent bullets and shotgun pellets are discharged into America’s landscapes. On impact, that lead fragments into carcasses and gut piles, where scavenging wildlife — including bald eagles, golden eagles, condors, hawks, ravens, and foxes — ingest toxic shards. The results are often acute poisoning, neurological impairment, reproductive failure, and death.

But this is not solely a wildlife conservation issue. Lead is a potent neurotoxin with no safe level of exposure. It does not biodegrade, and it can contaminate meat intended for human consumption while persisting in soil and ecosystems for decades.

Joseph is joined by two leading voices at the intersection of science and policy.

Wayne Pacelle, president of Animal Wellness Action and the Center for a Humane Economy, discusses the documented toll of lead poisoning on raptors and other wildlife, federal policy debates surrounding National Wildlife Refuges, and the proposed LEAD Act — legislation aimed at reducing toxic ammunition on public lands.

Dr. Aisha S. Dickerson, Assistant Professor of Epidemiology at the Johns Hopkins Bloomberg School of Public Health, brings critical scientific insight into how lead behaves biologically, why even low-level exposure can cause lasting neurological harm, and what environmental neuroepidemiology tells us about risks to both wildlife and humans.

Together, they explore:

• The biological mechanisms of lead toxicity
• Why there is no safe level of exposure
• The documented scope of wildlife mortality linked to ammunition fragments
• Public health implications for communities and families
• Policy pathways and practical alternatives available to hunters

This episode challenges listeners to consider tradition, science, and stewardship — and the responsibility we share in protecting both wildlife and public health.
