Potatoes, one of the world's staple crops, were included in the Environmental Working Group's (EWG) "Dirty Dozen" list for 2025, stirring concern in the potato sector. The EWG annually maps fruits and vegetables with the highest pesticide residues, drawing on data from the USDA's Pesticide Data Program (PDP). However, prominent voices in science, such as immunologist Dr. Andrea Love, contest the list's methodology as flawed.
Dr. Love analyzed EWG's tactics via her ImmunoLogic newsletter, also shared by the Genetic Literacy Project. She notes EWG omits toxicological context, focusing merely on residue presence without considering EPA safety limits. Love states that detectable pesticide levels don't inherently mean risk, likening it to finding a drop of water in an Olympic pool and deeming it unsafe.
Most concerning for industry experts and nutritionists is the list's influence on consumer behavior, potentially deterring produce consumption. Health organizations, like the CDC and WHO, advocate for increased produce intake to combat chronic diseases. The stated worry is that EWG's portrayal might discourage those without access to organic options.
Particularly for the potato industry, such messaging could mislead public perception, especially when misconceptions about potatoes' nutritional content persist. Critics argue the list accentuates residues, disregarding the health benefits and safety of conventional produce.
Dr. Love remarks on the implied safety superiority of organic over conventional farming in the Dirty Dozen list. She notes organic farms do utilize pesticides though from natural origins. This perceived gap fuels misinterpretation as natural does not equate to safer. USDA programs seldom test organic residues, contributing to a skewed view of "clean" food.
Studies highlight that pesticide residues in both organic and conventional produce remain well below safety thresholds. Dr. Love stresses the need for affordable access to produce regardless of farming methods to bridge nutritional inequities.
The focus on potatoes in the Dirty Dozen is critiqued as their residues are minimal, and cooking further reduces potential exposure. Potatoes contain vital nutrients like potassium and vitamin C. As essentials for food security, vilification of such crops overlooks their dietary contributions.
Dr. Love and others argue for scientifically grounded communication over fear-driven narratives. She asserts that produce safety shouldn't be simplified to binary distinctions, advocating for increased fruit and vegetable consumption.
For the potato industry and supporters, this annual debate over the EWG list is seen as a chance to correct misconceptions and inform the public about data-backed realities.
