The Environmental Protection Agency (EPA) has recently approved the use of ten pesticide products containing isocycloseram, a type of per- and polyfluoroalkyl substance (PFAS), on a wide range of crops including potatoes, citrus, tomatoes, and leafy greens. This decision has sparked alarm among scientists and health advocates, who warn of potential long-term health and environmental risks.
What Are PFAS and Why Are They Dangerous?
PFAS, often called “forever chemicals,” are synthetic compounds known for their extreme stability. This means they don’t break down in the environment or the human body, accumulating over time in soil, water, and living tissues. Exposure to PFAS has been linked to immune suppression, hormone disruption, and increased cancer risks. The approval of isocycloseram brings these risks directly into the food supply.
The EPA’s Rationale vs. Scientific Findings
The EPA maintains that when used as directed, the benefits of pest control outweigh potential risks. However, internal EPA studies identified concerning effects in animal tests, including reduced fertility and liver damage. Scientists also warn that isocycloseram doesn’t just remain as one compound; it breaks down into 40 smaller PFAS chemicals, amplifying its environmental presence.
The Threat to Pollinators and Human Development
Beyond direct human health impacts, isocycloseram poses a significant threat to pollinators like bees. Studies show exposure levels near treated fields can exceed lethal doses by 1,500 times, further jeopardizing already declining pollinator populations. Moreover, PFAS accumulate in human tissues, including the brain, lungs, and even breast milk. This means exposure can begin in utero, impacting developmental health in critical windows. The EPA did not include child-safety buffers in the approval, despite children’s higher vulnerability to chemical exposure.
How to Mitigate Your Exposure
Consumers concerned about PFAS contamination can take steps to reduce their risk:
- Prioritize organic produce: Organic certification prohibits synthetic PFAS pesticides.
- Shop local: Farmers’ markets allow direct questioning of pest management practices.
- Wash produce thoroughly: Though washing won’t remove systemic contamination, it reduces surface residues.
- Filter water: Certified water filters can remove PFAS from drinking water.
- Advocate for policy change: Contacting representatives can push for stronger regulations.
The approval of PFAS pesticides highlights a growing conflict between short-term agricultural gains and long-term public health. Informed consumer choices and policy advocacy remain critical tools to address this emerging threat.
