A new report on food safety is raising fresh concerns about what may be lingering on everyday fruits and vegetables. The annual “Dirty Dozen” list, released by the Environmental Working Group, found that nearly all tested samples of certain produce contained pesticide residues, including chemicals that can remain in the environment for years.
The findings are based on data from the United States Department of Agriculture, which tested tens of thousands of produce samples after washing and preparing them in ways that reflect typical consumer habits. Even after those steps, traces of hundreds of pesticides were still detected.
Leafy greens and berries top the list
At the top of the 2026 list is spinach, which showed the highest levels of pesticide residue by weight. According to the report, samples of spinach often contained multiple types of pesticides, making it one of the most heavily treated items.
Other commonly consumed foods also ranked high. Strawberries, grapes and several other fruits and vegetables were found to carry notable levels of pesticide residues. These items are widely popular, especially among children, which has added to the concern raised by researchers.
Each type of produce on the list was found to contain multiple pesticide traces on average, pointing to repeated exposure from different chemicals rather than just a single source.
The full Dirty Dozen list
The report identifies 12 fruits and vegetables with the highest pesticide levels. These include spinach, strawberries, grapes, nectarines, peaches, cherries, apples, blackberries, pears, potatoes and blueberries.
The consistent presence of multiple pesticide residues across these foods has sparked discussions about cumulative exposure. Experts suggest that consuming produce with several different chemicals may increase potential health risks over time.
While washing and peeling can reduce some residues, they may not remove all traces, especially when pesticides are absorbed into the food itself.
Concerns over long-lasting chemicals
One of the most notable findings in this year’s report is the presence of substances known as PFAS, often referred to as “forever chemicals.” These compounds are known for their durability and can persist in the environment for extended periods without breaking down.
The report found that a significant portion of tested samples contained pesticides linked to these chemicals. Because of their persistence, PFAS have been associated with a range of health concerns in past studies, including effects on the immune system and other long-term health risks.
Their presence in food has drawn increased attention from researchers and public health advocates.
Potential health risks highlighted
Past research has linked pesticide exposure to several health issues, including complications during pregnancy, developmental concerns in children and increased risk of certain chronic conditions.
Children are often considered more vulnerable due to their developing bodies and higher sensitivity to environmental toxins. Exposure during pregnancy and early life has been associated with a range of outcomes, including lower birth weight and developmental challenges.
While the levels found in produce are typically regulated, the combined effect of multiple chemicals remains an area of ongoing study.
Industry groups push back
Not everyone agrees with the interpretation of the findings. Groups representing farmers and the agricultural industry emphasize that pesticide use is strictly regulated and monitored.
They point out that the presence of residue does not necessarily mean the food is unsafe, noting that safety limits are set with wide margins to protect consumers. According to these groups, the majority of tested produce falls within acceptable safety thresholds.
This ongoing debate highlights the complexity of balancing food safety, farming practices and public health concerns.
Ways to reduce exposure
Experts continue to stress that fruits and vegetables remain essential to a healthy diet. Rather than avoiding produce altogether, they recommend making informed choices.
The report also includes a “Clean Fifteen” list, which identifies produce with the lowest levels of pesticide residue. Items like pineapple, sweet corn and avocados were among those found to have minimal contamination.
Washing produce thoroughly, peeling when appropriate and choosing organic options for higher-risk items are some of the steps that may help reduce exposure. Eating a wide variety of fruits and vegetables is also encouraged to balance potential risks.
Why it still matters
The latest findings underscore an ongoing conversation about food safety and environmental health. While produce continues to play a vital role in nutrition, understanding what may be present on these foods allows consumers to make more informed decisions.
As research continues, the focus remains on finding ways to maintain both safety and accessibility in the food supply.
