Americans’ toxin – From formaldehyde exposures after Hurricane Katrina to today’s worry about food, packaging, and kids’ products, Americans’ fixation on toxins is fueled by real harms—then amplified by distrust, politics, and a gap between consumer choices and environmental pol
In the months leading up to the 2024 election, Robert F. Kennedy Jr. framed the modern world in stark biological terms—toxins “permeat[ing] every cell of our bodies. ” with an “unrelenting” assault on “our children’s cells and hormones.” He warned that “they are swimming around in a toxic soup. ” and that “We are mass poisoning all of our children and all of our adults.”.
The language was dramatic. But it landed in a culture already primed to listen.
More than 70 percent of US adults. according to a Pew Charitable Trusts survey earlier this year. say they worry about exposure to harmful chemicals in food and drinking water. More than half say they have the same concerns about food packaging and kids’ products. The vast majority want the government and businesses to do something about it.
That’s not just political talk or a one-off fad. The fixation has seeped into everyday life and even pop music—Olivia Rodrigo’s “The Cure,” from her new album, includes the chorus line, “I’ve got toxins in my bloodstream.”
To understand why the fear feels so widespread. I spoke earlier this month with four experts: two anthropologists. a biologist. and an environmental researcher. Their accounts share a single through-line—Americans are anxious about toxins because the idea of chemical harm is rooted in evidence. but the way that fear turns into action often collides with mistrust. ideology. and how regulation is actually built.
At the center of the obsession is distrust—stitched together by catastrophe and data
Part of the reason Americans keep returning to toxins is that there is “strong scientific evidence that some chemicals can cause harm to human health. ” said Kim Fortun. an anthropologist at University of California Irvine. Fortun’s career began with research into the 1984 Union Carbide India Limited pesticide plant disaster—one of the worst industrial disasters in history. Hundreds of thousands of people were exposed to toxic chemicals and thousands died.
She described that kind of harm as searing in a way that’s hard to shake. Nicholas Shapiro. an environmental researcher at UCLA. traced another kind of public injury: the large formaldehyde exposure experienced by thousands of Americans when they were put up in provisional housing following Hurricane Katrina in New Orleans. “The largest formaldehyde exposure in our species’ history” is how Shapiro described it.
Those disasters are not constant, though. As the experts discussed it, one-off catastrophes have become mercifully more rare. At the same time. attention has shifted toward long-term. low-grade exposures—everyday substances that don’t always dominate headlines. but that research increasingly suggests can harm people over time.
In that setting, the Pew survey reads less like a weird obsession and more like a response to a world where the risks feel both real and persistent.
Fortun said, “The science is in.” Shapiro described how his work moved from the acute formaldehyde exposures after Hurricane Katrina to the more mundane exposure many people face living in housing built with formaldehyde-laden materials.
For many Americans, the conclusion is straightforward: the world is inherently toxic. The survey reflects that belief—and the experts say broader social and political trends help make it louder.
Alex Nading. a medical and environmental anthropologist at Cornell University. pointed to how the Make America Healthy Again movement—often called MAHA—can pull people from across the political spectrum. One shared feature. Nading said. is “a…suspicion of corporate power.” He added that the movement also carries “a nostalgia or at least a veneration of a pure environment that doesn’t really have. necessarily. always a party attached.”.
Fortun put the distrust in historical terms. “I don’t think distrust of institutions is at all a natural phenomena. It’s historically produced.” And she described a narrative that taps into that history: the feeling that no one was watching while chemicals moved into people’s bodies.
“No one was minding the store when they’re chemically exposing us,” Fortun said.
That worldview can be politically useful because it simplifies blame—corporations are poisoning people, and the government is failing to stop it. The experts didn’t argue that the concerns are imaginary. They argued that the story people tell themselves can end up flattening a messier reality.
The left and right don’t just disagree on policies—they start from different ideas about “purity” and “control”
Even if the alarm is shared, the response is not.
One sharp divide runs through how pollution is understood. Environmentalists have long treated pollution as a racial and social justice issue, Nading explained. “The choice to pollute and where you pollute is really saying something about race relations.” Those concerns start with humans—how pollution affects people. and which people bear the cost.
Other people begin with a different instinct. They see chemicals as an attack on the body and look for purity or for a remedy that feels like personal sovereignty.
Fortun described it this way: the right tends to be driven by “a desire for purity, the integrity of the body.” She also said another difference between the left and right is that the right is “really driven” by that impulse.
Nading framed it with two competing instincts: “There’s that ‘regulate’ impulse. And then the other side of it is: Gain control. Assert sovereignty.”
In the MAHA moment, the latter outlook seems to be more dominant. Kennedy’s warning that toxins “permeat[ing]] every cell” reinforces an image of harm that can feel total—something that lives inside you rather than something that concentrates where policy and enforcement decide.
That mindset can pull people toward individual consumption choices first and foremost—shopping for the “right” products. scanning labels. and worrying about what goes into a body. Shapiro said government regulations have evolved to focus more on consumer products than on the built environments where people live.
So the anxiety ends up routed through commodities: sunscreen, foods people eat, and microplastics in children’s toys and diapers.
At the same time, Shapiro noted that foundational environmental laws meant to clean up the air and water have been undermined in recent years, without the same collective fixation or uproar.
“The regulation is tricky,” in essence, is what Shapiro’s description points toward—especially because air is treated differently than food and water in how exposure is understood.
“Air is the primary source of exchange between our bodies and the environment. We inhale much more by weight…than we do food or water,” Shapiro said. “So it’s interesting that we really understand our exposure through commodities as opposed to the substance of life, which is air.”
Americans need a way to talk about toxins that doesn’t trap them in either panic or consumer blame
There’s a particular kind of hopelessness that comes from seeing long lists of scientific-sounding chemical names. The experts described that emotional trap as predictable—especially when microplastics and nanoplastics feel everywhere and their health impacts feel uncertain.
Gerald LeBlanc. a biologist at North Carolina State University and author of Everyday Chemicals: Understanding the Risks. said people can confuse hazard with harm. “There is a difference between a substance being hazardous (meaning it could potentially cause harmful health effects) and it actually doing harm. ” he explained.
Both LeBlanc and Nading emphasized one principle: “The dose makes the poison.”
LeBlanc said people are often drawn only to hazard—the idea of what a chemical can do—without considering exposure.
“People are prone to think only about hazard. What can this chemical do to me with no consideration of exposure?” he said. “People think about the mere presence of a chemical as being problematic. You really need to think about the dose that an individual is receiving along with the hazard or the toxicity of that material.”.
But that framework comes with a warning of its own. It can place heavy responsibility on individuals: you have to learn not just whether a substance is risky, but how much exposure you might actually be getting.
It’s also easy for misinformation to flourish when “presence” becomes confused with “danger.” The experts pointed to MAHA and Kennedy’s obsession with aluminum in vaccines as an example of how intuitive reactions can break down when safety data is examined. Kennedy’s focus makes it sound like metals in a vaccine must be bad; only by looking into safety data. the discussion went. can you learn it has been proven to be safe.
In that sense, the experts described modern medicine as increasingly DIY. That requires a sharper ability to evaluate medical data and research.
If people want to advocate for themselves. LeBlanc’s concerns—reinforced by what Nading and Shapiro discussed—suggest they should not simply trust confident content creators from TikTok reels. The conversations stressed learning the difference between peer-reviewed research and preprints, and the gap between animal-based research and human studies.
And if people are wary of the CDC or FDA, the experts pointed readers to local or state health departments as a more trusted source for some communities in the post-pandemic era.
But “smarter consumers” shouldn’t become a substitute for government action. The experts were clear that the long game requires structural change.
A productive path forward means organizing now—before the fear burns out
For Shapiro, the fear itself may not last forever in its current form. He told me he believes the nostalgia many people feel—an idealized past free from chemicals—is “going to run out of gas.” We are not going to “roll back the Industrial Revolution,” he said.
So the question becomes what happens after the alarm.
The experts described community organizing as a way to redirect fear into action that doesn’t stop at product labels. The practical starting point is building relationships with neighbors who share the concern and learning what is happening in a city or state.
States have their own rules around pesticides and clean air. People were urged to get up to speed on laws and policy changes moving through local government—and to identify which organizations and advocacy groups are working toward policy reforms aligned with their goals.
Shapiro specifically urged concerned public health workers to connect now with MAHA-curious people in their lives and communities. He pointed to a Bible study model where small groups meet. talk through evidence. and brainstorm solutions aimed at the structural sources of toxins—not only in consumer products. but in the air people breathe and the water people drink.
In the end. the experts’ message is less about treating toxin fear like a punchline and more about acknowledging the emotional reason it spreads: real harms happened. evidence exists. and trust is hard to rebuild. The hard part is translating that into action that reaches beyond the individual—before the conversation loses its urgency to outrage. uncertainty. or exhaustion.
