Organophosphate pesticides (chlorpyrifos / malathion)
Toxins · Acetylcholinesterase inhibitor
High priority
Bottom line
Read Off Label rates Organophosphate pesticides (chlorpyrifos / malathion) a HIGH avoidance priority (8.0/10) based on strong evidence of high harm magnitude and high occupational/agricultural exposure prevalence.
Chlorpyrifos regulatory saga: EPA 2021 food use ban was vacated in court 2023, then EPA re-banned in 2024 for most uses.
The intervention here is reducing exposure, not adding a compound.
What this is
Chlorpyrifos regulatory saga: EPA 2021 food use ban was vacated in court 2023, then EPA re-banned in 2024 for most uses. Ongoing litigation. Developmental window is critical — prenatal/early childhood exposure drives the strongest evidence base. EWG Dirty Dozen/Clean Fifteen lists are a reasonable shopping heuristic.
Mechanism
Acetylcholinesterase inhibitors — same mechanism as nerve agents but lower potency; agricultural pesticides; chlorpyrifos banned on food crops by EPA 2021 after long fight; developmental neurotoxicity documented
Dose & route
Conventional produce rinse (reduces residue ~70%); EWG Dirty Dozen; organic for pregnant women/kids especially
