The Poison Squad: One Chemist's Single-Minded Crusade for Food Safety at the Turn of the Twentieth Century

At the dawn of the twentieth century, American food production was unregulated and often lethal. Deborah Blum documents the work of Harvey Washington Wiley, a government chemist who challenged the powerful food industry to expose the widespread use of toxic preservatives like formaldehyde, borax, and salicylic acid. Wiley conducted human experiments—the titular Poison Squad—where volunteers consumed these additives to prove their harmful effects. The narrative follows Wiley’s decades-long political battle against corporate lobbyists and corrupt bureaucrats to pass the 1906 Pure Food and Drug Act and establish the foundations of the FDA.

Readers interested in the intersection of chemistry, public policy, and industrial history will find this a detailed account of how consumer protections are built. Those who study the Gilded Age or the origins of government oversight read this to understand the specific chemical maneuvers once used to disguise rotting meat and adulterated milk. The reader finishes with a clear view of the scientific methods used to identify toxins and the legislative friction required to remove them from the American diet.
