What if we told you that a chemical that is commonly sprayed on apples, wheat, and citrus fruits could permanently damage your child’s brain before they’re even born?
That’s exactly what a groundbreaking study from Columbia University has confirmed: prenatal exposure to chlorpyrifos, a widely used pesticide, causes lasting brain damage that persists into adolescence.
The study, published in JAMA Neurology, tracked 270 children from birth through age 14, using advanced brain imaging to document the devastating effects of chlorpyrifos exposure. The findings are alarming: higher pesticide exposure led to thicker brain tissue, reduced blood flow, altered white matter, and worse motor skills in changes so severe that researchers could predict exposure levels just by looking at brain scans.
This isn’t just about subtle differences; it’s about permanent neurological harm that affects how these children think, move, and function for life.
Chlorpyrifos is an organophosphate pesticide, a class of chemicals originally derived from nerve gas used in warfare. Despite being banned for household use in 2001, it’s still sprayed on apples, cherries, peaches, citrus fruits, and wheat, which means pregnant women and children are exposed through food, air, and dust.
The study found that chlorpyrifos crosses the placenta and concentrates in fetal blood at four times the mother’s levels, attacking developing brain cells. The result? Oxidative stress, inflammation, and mitochondrial damage that disrupt normal brain development.
Dr. Bradley Peterson, lead author of the study, warned: “With more exposure, we saw more brain effects, but there is no level below which you don’t see impacts.” That means even low-level exposure is dangerous, yet regulators continue to allow its use.
The EPA first proposed banning chlorpyrifos in 2015, but political interference and industry lobbying have delayed action for nearly a decade. Under Trump, the EPA rejected a ban entirely. Even after a federal court ordered a ban in 2021, another court reversed it in 2023, allowing continued use on 11 major crops.
This regulatory whiplash isn’t just frustrating; it’s deadly. As Patti Goldman, a senior attorney for Earthjustice put it: “We do not believe they should keep any uses because there is no safe level that would protect children from the kind of harm observed in the study.”
Yet the EPA’s current proposal still allows chlorpyrifos on 55% of its previous uses, including staples like apples and wheat. Meanwhile, the European Union banned it entirely in 2020 because they prioritize children’s health over corporate profits.
Since regulators won’t act, families must take matters into their own hands:
Pesticides are rewiring our children’s brains, and the fact that chlorpyrifos is still legal despite decades of evidence shows how deeply corporate greed has corrupted our regulatory system.
As Dr. Virginia Rauh, senior author of the study, warned: “Current widespread exposures continue to place farmworkers, pregnant women, and unborn children in harm’s way.”
How much longer will we let this happen? The time for action is now, before another generation of children pays the price.
