The Environmental Working Group has released its 2026 Shopper’s Guide to Pesticides in Produce, renewing debate among food safety experts over the health implications of pesticide residues found on fruits and vegetables.
This year’s report introduces a new concern involving PFAS-based pesticides, commonly referred to as “forever chemicals” because of their persistence in the environment and human body.
The annual guide ranks produce items according to pesticide residue data collected by the United States Department of Agriculture through testing conducted on thousands of food samples.
What the “Dirty Dozen” Measures
The “Dirty Dozen” list identifies fruits and vegetables with the highest detected levels and variety of pesticide residues, while the “Clean Fifteen” highlights produce with the lowest detectable residue levels.
However, food safety scientists and toxicologists argue that the presence of pesticide residue does not necessarily mean the food poses a health risk.
Researchers note that regulatory agencies establish safety limits designed to remain well below levels considered harmful to human health.
Several experts have criticized the annual list for potentially creating unnecessary fear around conventionally grown produce, especially since many studies continue to show that fruit and vegetable consumption provides major health benefits.
Scientists Question Risk Interpretation
According to food safety researchers, recent scientific analyses found that estimated pesticide exposure levels from produce consumption remain significantly below health-based safety limits established by regulators.
Some analysts argue that consumers would need to consume extremely large quantities of certain produce items daily to approach existing safety thresholds.
Despite the criticism, the Environmental Working Group maintains that the guide is intended to help consumers make informed choices rather than discourage fruit and vegetable consumption.
The organization has also raised concerns that some current pesticide regulations may not fully account for long-term exposure, combined chemical effects, or newer environmental risks linked to PFAS compounds.
Produce Items Listed in the 2026 Dirty Dozen
The 2026 “Dirty Dozen” list includes:
- Spinach
- Kale, collard, and mustard greens
- Strawberries
- Grapes
- Nectarines
- Peaches
- Cherries
- Apples
- Blackberries
- Pears
- Potatoes
- Blueberries
The report stated that residues from 203 different pesticides were detected across samples included in the list.
The organization also identified green beans and bell peppers among produce items with relatively higher toxicity scores outside the main ranking.
“Clean Fifteen” Produce List
The guide’s Clean Fifteen list for 2026 includes produce with the lowest detectable pesticide residue levels, including:
- Pineapple
- Sweet corn
- Avocados
- Papaya
- Onions
- Frozen sweet peas
- Asparagus
- Cabbage
- Cauliflower
- Watermelon
- Mangoes
- Bananas
- Carrots
- Mushrooms
- Kiwi
Researchers reported that nearly 60 per cent of samples from these foods showed no detectable pesticide residue.
Growing Attention on PFAS Chemicals
A major focus of this year’s report is the detection of PFAS-related pesticides in produce samples.
PFAS chemicals are known for their resistance to breaking down naturally, raising environmental and health concerns among scientists.
The report identified residues of the PFAS pesticide fludioxonil in several produce samples, particularly peaches and plums. Other PFAS-related chemicals, including fluopyram and bifenthrin, were also frequently detected.
Health researchers say studies examining the long-term effects of PFAS pesticide exposure are still ongoing, and experts continue to call for further scientific investigation into their potential impact on public health.
Despite ongoing debate surrounding pesticide rankings, nutrition experts continue to encourage regular fruit and vegetable consumption as part of a balanced and healthy diet.
