A Toxic Combination: Forever Chemicals Are Adding to the Health Risks of Pesticides

Two recent studies, one conducted by Consumer Reports and published in May 2024, and another published in Environmental Health Perspectives in July 2024, suggest that exposure to toxic synthetic pesticides continues to be a serious issue and a growing threat to human, animal and environmental health.
Now, add forever chemicals into the mix, as environmental advocacy groups found that 66 active ingredients currently approved for use in pesticides qualify as PFAS, also known as “forever chemicals.”
In addition, according to the study, “Forever Pesticides: A Growing Source of PFAS Contamination in the Environment,” eight approved “inert” ingredients – added to pesticides to help chemicals disperse and stick to the plants, for example – also qualify as PFAS. The research was conducted by the Center for Biological Diversity, Public Employees for Environmental Responsibility and the Environmental Working Group, and was published in the journal Environmental Health Perspectives.
Most Comprehensive Pesticide Review Ever
According to the Consumer Reports study published in May, the advocacy group conducted “our most comprehensive review ever of pesticides in food,” looking at 59 common fruits and vegetables (fresh versions, and in some cases, also canned, dried and frozen fruits and vegetables) and analyzing seven years of data from the U.S. Department of Agriculture. USDA annually tests a selection of conventional and organic produce grown in or imported to the U.S. for pesticide residues.
“Our new results continue to raise red flags,” said Catherine Roberts on behalf of Consumer Reports. “Pesticides posed significant risks in 20% of the foods we examined, including popular choices such as bell peppers, blueberries, green beans, potatoes, and strawberries. One food, green beans, had residues of a pesticide that hasn’t been allowed to be used on the vegetable in the U.S. for over a decade. And imported produce, especially some from Mexico, was particularly likely to carry risky levels of pesticide residues.”
Added Roberts, “When it comes to healthy eating, fruits and vegetables reign supreme. But along with all their vitamins, minerals and other nutrients can come something else: an unhealthy dose of dangerous pesticides.” Science has strongly linked pesticide exposure to increased risks of cancer, diabetes, neurological and childhood development issues, and many other health problems.
PFAS: Compounding the Concern
Compounding the concern of pesticide pollution is the discovery that PFAS chemicals are being used in many of the toxic, synthetic pesticide formulations approved for use on farms across the U.S., raising questions about the long-term consequences of such pernicious substances enduring for decades in our soil and water. According to the Environmental Protection Agency, these chemicals “break down very slowly and can build up in people, animals, and the environment over time.”
PFAS have been linked to cancer, reproductive issues and developmental delays in children, among other adverse health effects. To make matters worse, the researchers who published the Environmental Health Perspectives report found that a process called fluorination, which can create PFAS chemicals, is being used increasingly in the manufacture of pesticides to make them stick around for longer, Civil Eats reported.
“This is truly frightening news, because pesticides are some of the most widely dispersed pollutants in the world,” said Nathan Donley, Environmental Health Science Director for the Center for Biological Diversity and one of the study’s authors. “Lacing pesticides with forever chemicals is likely burdening the next generation with more chronic diseases and impossible cleanup responsibilities. The Environmental Protection Agency needs to get a grasp on this fast-emerging threat right away.”
“Toxic PFAS have no place in our food, water or homes, posing a serious threat to our health and environment,” said David Andrews, Ph.D., Deputy Director of Investigations and a Senior Scientist with the Environmental Working Group, a co-author of the study. “The increasing use of PFAS pesticides will lead to increasing levels of PFAS in the environment. PFAS not only endanger agricultural workers and communities but also jeopardize downstream water sources, where pesticide runoff can contaminate drinking supplies. From home gardens to pet care, the use of these pesticide products further illustrates why we must end all non-essential uses of these persistent forever chemicals,” Andrews added.
Choose Organic
Based on Consumer Reports’ research, the largest risks of dietary exposure to pesticide residues are caused by just a few pesticides concentrated in a handful of fruits and vegetables. Their findings also indicated that nearly all of the organically produced fruits and vegetables tested presented little to no risk.
To help educate consumers, Consumer Reports produced a printable guide showing the risk in produce from pesticides in both their conventional and organically produced counterparts, as well as whether they are grown domestically or imported.
Consumer Reports advised, “A proven way to reduce pesticide exposure is to eat organic fruits and vegetables, especially for the highest-risk foods. We had information about organically grown versions for 45 of the 59 foods in our analysis. Nearly all had low or very low pesticide risk, and only two domestically grown varieties—fresh spinach and potatoes—posed even a moderate risk. Organic foods’ low-risk ratings indicate that the USDA’s organic certification program, for the most part, is working,” Consumer Reports said.
“Less pesticide on food means less in our bodies: Multiple studies have shown that switching to an organic diet quickly reduces dietary exposure. Organic farming protects health in other ways, too, especially for farmworkers and rural residents, because pesticides are less likely to drift into the areas where they live or to contaminate drinking water,” Consumer Reports added.
However, of concern to advocates of organic agriculture, the report also showed that imported organic green beans had a very high pesticide risk – “the exact same rating as imported conventional green beans,” said Max Goldberg, Publisher of Organic Insider, in commenting on the study. Additionally, Consumer Reports findings indicated that U.S. grown organic spinach presented a “moderate” pesticide risk – “the exact same rating as both U.S.-grown and imported conventional Spinach,” Goldberg noted. U.S.-grown organic potatoes also presented a moderate risk, as did imported organic kale, according to USDA data analyzed by Consumer Reports.
While organic agriculture does allow for certain pesticides to be used, they are low-risk and derived from natural mineral or biological sources that have been approved by the USDA’s National Organic Program, said Goldberg, a renowned advocate for organic food and agriculture. Additionally, he noted, chemicals linked to human health and environmental issues, such as glyphosate or neonicotinoids, are prohibited in organic.
“The organic system is not fool-proof, and organic farmers may have persistent pesticides in their soil that have not degraded after the three-year transition period. Or, they may be the victim of pesticide drift from neighboring conventional farms. That being said, any fruit or vegetable that has a moderate, high or very high pesticide risk is a very serious red flag and should call for an immediate investigation. The fact that Consumer Reports looked at nearly 30,000 fruit and vegetable samples would invalidate an ‘isolated incident’ excuse,” Goldberg asserted.
“One of the primary reasons that we are paying extra to buy organic is specifically to avoid these chemicals. And yet, not only do imported organic green beans pose a very high pesticide risk, but they, along with U.S.-grown organic spinach, pose the exact same pesticide risk as their conventional counterparts,” he said.
“In the interim, retailers and brands must demand that their suppliers conduct third-party pesticide testing for all organic fruits and vegetables, or at a bare minimum, for all imported organic green beans and organic kale, and U.S.-grown organic spinach and organic potatoes. This will help identify who the bad actors are, so they can be removed from the system. We have no choice but to be unrelenting when it comes to pesticide contamination of organic fruits and vegetables,” said Goldberg.
