chlorpropham

Nearly all potato samples contain pesticide not approved for use in the EU    (EWG,  June 11, 2025)    'Potatoes – the most consumed vegetable in the U.S. – join this year’s Dirty Dozen™ in twelfth place. The reason: high concentrations of chlorpropham, a plant growth regulator banned in the European Union due to health concerns.    From 2022 to 2023, the Department of Agriculture collected and tested more than 1,000 samples of potatoes. They washed and scrubbed the samples, then tested for pesticide residues. Ninety percent of the samples contained residues of chlorpropham.  The average concentration across all samples was nearly three parts per million – high concentrations relative to most other pesticides detected across produce. And the concentrations are twice the level that the Environmental Protection Agency used in its most recent assessment of chlorpropham from 2017.     The chemical was detected on 90% of U.S. potato samples. Since 1990, chlorpropham has mostly been used on potatoes in the U.S. to prevent them from sprouting during storage.   SNAP Comment: I have seen Canadian potaotes in US stores before. There are 26 chlorpropham containing pesticides currently regeistered in Canada so it is very likely found on non-organic potatoes sold in Canada.
