Regulatory Uncertainty and Neurotoxic Residues in U.S. Foods: QuEChERS Analysis

Overview

Since 1966, the organophosphate chemical Chlorpyrifos has occupied a controversial role in US agricultural production as a pesticide. With mounting pressure for the chemical’s ban, however, a 2017 ruling found chlorpyrifos neurotoxic and imposed a zero -tolerance on the compound. Later policy then overturned this ban in 2023, creating widespread panic among industry professionals about the chemical’s use. While the policy has since been revised to support the earlier restrictions, a nearly year -long gap in e nforcement remains, making the neurotoxic chemical a potential threat to US public health. This study seeks to establish whether or not legal precedent as a means of controlling current use deterred the industry from Chlorpyrifos, measuring the chemical’s content in ten historically saturated crops from various jurisdictions. To accomplish this task, the researcher coordinated with the CVUA Stuttgart Laboratory to conduct a QuEChERS test of the collected samples, lending in high-accuracy results. Contrary to expectations, chlorpyrifos residues were largely undetected. However, high concentrations of chlorates and other hazardous chemicals were observed during a multi-residue analysis, raising questions about the future of American food safety. The absence of chlorpyrifos, too, suggests several potential vectors for precedent -based regulatory processes, as well as a cautious approach to future governmental administrations. The researcher aims to use this data to advocate for further stability in regulatory frameworks, as well as caution against similarly dangerous and uninformed policy reversals. DoDEA Pacific
