Misled on lead: The campaign to keep toxic lead in hunting ammo and fishing tackle

Hunting and fishing have a science denial problem.

EHN investigated hundreds of claims from webpages, documents, and testimony, and found that groups including the Congressional Sportsmen’s Foundation (CSF), the National Shooting Sports Foundation (NSSF), and the National Rifle Association (NRA) spread misinformation and engage in science denialism most of the time they communicate about lead ammunition or fishing tackle.


Lead poisoning “is killing large numbers of animals in a manner that is often prolonged, painful, and cruel. Whether it causes heart, kidney, reproductive, or nervous system problems, there is strong scientific evidence to show that any quantity of lead can be harmful," said Mark Pokras, a wildlife veterinarian and Associate Professor Emeritus at Tufts Cummings School of Veterinary Medicine.

What we found

  • Similar to Big Tobacco and climate change denial, groups are using the five categories of denialist techniques— fake experts, cherry picking, impossible expectations, conspiracy theories, and logical fallacies—to keep lead in ammo and fishing tackle.
  • Hunting and fishing—including the purchase of ammunition and fishing tackle—are crucial components of U.S. conservation funding, which leaves state wildlife agencies hesitant to address the lead issue.
  • Proponents of nonlead alternatives are divided on the path forward, fearful to address misinformation.

What needs to happen

Lead contamination from ammunition and fishing tackle sickens and kills wildlife. And we previously reported that lead contamination in hunted meat has the potential to impact the health of millions of people in the U.S., including low-income recipients of venison donations.

This means majestic bald eagles are being poisoned, as well as children who eat hunted meat. This needs to change.

Ammunition and fishing tackle manufacturers, and retailers that carry their products, need to acknowledge the toxic nature of lead ammo and fishing tackle.

State wildlife agencies need to be transparent about the toll lead has on wildlife health.

Lawmakers need to use science—not propaganda—in setting regulations.
