What the 2026 Dirty Dozen's 'Forever Chemical' Finding Means for Your Health
The Environmental Working Group’s 2026 Dirty Dozen list has a new concern this year beyond traditional pesticides: PFAS “forever chemicals” detected in pesticide residues on fruits and vegetables Americans eat regularly.
PFAS compounds do not break down easily in the environment or the body, and their presence in the food supply adds a new layer to grocery decisions — especially for anyone already paying attention to cumulative chemical exposure over time.
That said, experts and the USDA are consistent on this point: all conventionally grown produce sold in the U.S. meets federal safety standards. The Dirty Dozen is a smarter shopping tool, not a reason to eat fewer fruits and vegetables.
The 2026 Dirty Dozen
Ranked by pesticide residue levels, this year’s list:
- Spinach (most residue by weight, avg. 4+ types per sample)
- Kale, collard and mustard greens
- Strawberries
- Grapes
- Nectarines
- Blackberries (newly added, avg. 4+ pesticides per sample)
- Peaches
- Cherries
- Apples
- Pears
- Potatoes
- Blueberries
The PFAS finding is broad: 63% of Dirty Dozen samples contained PFAS pesticide residues. The most common was fludioxonil, a fungicide found in nearly 90% of peach and plum samples. On potatoes specifically, chlorpropham (a sprout inhibitor already banned in the European Union) turned up in 90% of U.S. samples. Organic certification prohibits PFAS pesticides, so the USDA Organic seal on Dirty Dozen items is the most direct way to avoid them.
Where You Can Buy Conventional
The Clean Fifteen offers real relief for budget-conscious shoppers. This year’s list: pineapple, sweet corn, avocados, papaya, onions, frozen sweet peas, asparagus, cabbage, cauliflower, watermelon, mangoes, bananas, carrots, mushrooms and kiwi. Nearly 60% of samples from these items had zero detectable pesticide residues. Buying conventional here is a safe, practical call.
Seasonal Shopping Is Worth the Effort
In-season produce is picked at peak ripeness, which means higher vitamin and mineral content, better flavor and lower prices driven by seasonal abundance. The shorter the farm-to-table distance, the less nutrient loss in transit.
Spring 2026 picks include asparagus, artichokes, peas, spring onions, radishes and bok choy — several of which appear on the Clean Fifteen. New potatoes are also in season this spring; since potatoes land on the Dirty Dozen, organic is worth choosing here.
At the store, checking the country or region of origin on labels takes seconds and matters: local sourcing generally means shorter transit time and less time for pesticide absorption to deepen. Farmers markets let you ask growers directly about their practices. And frozen organic is a legitimate budget alternative: EWG’s own science analyst flagged it in 2026 coverage as a practical swap for fresh organic.
How to Wash Produce Effectively
Washing makes a measurable difference, and the method matters. Consumer Reports and FDA guidance both point to running water for at least 20 seconds with gentle rubbing as the most effective everyday approach. For firm produce like potatoes and carrots, use a clean vegetable brush.
For leafy greens, rinse under low-pressure warm water, spin dry in a colander and wash the colander after. For a more thorough clean, a baking soda soak (1 teaspoon per 2 cups of water for 12 to 15 minutes) outperforms plain water for surface pesticide removal, per University of Massachusetts research.
Skip soap, produce washes, bleach and detergents entirely. The FDA and USDA advise against them because produce is porous and can absorb those chemicals. Always wash before peeling to avoid dragging surface residue into the flesh. One exception: “triple-washed” bagged greens do not need an additional rinse, per the FDA.
Choosing organic on the 12 highest-residue items, leaning into seasonal buying and washing produce correctly are small, actionable shifts — ones that reduce exposure without cutting back on the produce your body benefits from every day.
