How to Sell a Poison

The story of an infamous poison that left toxic bodies and decimated wildlife in its wake is also a cautionary tale about how corporations stoke the flames of science denialism for profit.

The chemical compound DDT first earned fame during World War II by wiping out insects that caused disease and boosting Allied forces to victory. Americans granted it a hero’s homecoming, spraying it on everything from crops and livestock to cupboards and curtains. Then, in 1972, it was banned in the US. But decades after that, a cry arose to demand its return. 

This is the sweeping narrative of generations of Americans who struggled to make sense of the notorious chemical’s risks and benefits. Historian Elena Conis follows DDT from postwar farms, factories, and suburban enclaves to the floors of Congress and tony social clubs, where industry barons met with Madison Avenue brain trusts to figure out how to sell the idea that a little poison in our food and bodies was nothing to worry about.

In an age of spreading misinformation on issues including pesticides, vaccines, and climate change, Conis shows that we need new ways of communicating about science—as a constantly evolving discipline, not an immutable collection of facts—before it’s too late.

• “The phrase ‘trust the science’ should be replaced with ‘understand how the science gets made.’ This deeply researched, beautifully written, and well-argued explanation of how DDT was sold, misregulated, and resold should scare everyone from the ardent scientist to the fearful conspiracy theorist into rethinking.”
  Susan M. Reverby, author of Examining Tuskegee
• “What Merchants of Doubt did for earlier campaigns of corporate disinformation, How to Sell a Poison does, superbly, for a toxin I thought we’d gotten rid of. Elena Conis’s fast-paced account is all the more important in an era when powerful forces are trying to discredit science.”
  Adam Hochschild, author of King Leopold's Ghost
• “Elena Conis is a historian who writes nonfiction like a fiction writer. In elegant prose, she reveals the often forgotten and captivating history of how ordinary people discovered the dangers of DDT—and persisted in having it banned against all odds and despite false assurances of its safety from public health officials.”
  Sheldon Krimsky, author of GMOs Decoded
• "Why do we still talk about DDT? In this provocative and richly detailed retelling of the DDT story, Elena Conis deftly explores why a pesticide banned since 1972 remains so politically divisive. For Conis, the answer lies in the intersection of science and politics, revealing a story rooted in the past, but framed by contemporary political and ecological debates. It is a fascinating story that will resonate with readers trying to make sense of the uncertainty of scientific knowledge in our highly politicized world.” 
  David Kinkela, author of DDT and the American Century
• "Science is often thought to be the antonym of politics. Yet the human side of innovation, along with fierce competition, can create the conditions for behavior that is anything but apolitical. How to Sell a Poison brilliantly retells the story of the rise, fall, and reemergence of DDT to highlight how context shapes what we think we know about science and health policy. Rigorously researched and delightfully written, this book sets a new standard for science journalism."
  Osagie Obasogie, author of Blinded by Sight
• “In How to Sell a Poison, Elena Conis skillfully narrates the complex, toxic history of DDT, among the world’s most popular and dangerous chemical pesticides.  Initially heralded, ultimately banned, still widely used, the vagaries of the production, sale, and regulation of DDT opens up the most fundamental questions of corporate greed, the role of government, and scientific practice.  Anyone interested in the problem of scientific authority in our toxic world should read this important, essential book."
  Allan M. Brandt, author of The Cigarette Century
• "Elena Conis has rendered a frightening and thoroughly researched account of the poisoning of our environment and ourselves. With great precision and keen analysis, she plainly lays out the case for how one of the twentieth century’s most large-scale toxic exposure events was the direct result of corporate greed and manufactured doubt of science. The story always has been urgent, but no more so than now.”
