His Substack is Prime Factors and he is a 2026-2027 Knight-Wallace Fellow. Jun 5, 2025 3:42 PM UTC Various chemicals, from those in plastics to food additives, have made headlines lately for their potential roles in triggering diseases. Pesticides are unique among chemicals, though, says Melissa Perry, an environmental epidemiologist and dean of George Mason’s College of Public Health. “They’re deliberately manufactured to kill things.” By poisoning weeds, pesticides clear the way for farmers’ crops to thrive. But their deadly design may undermine human health, too. A recent [report](https://time.com/7288175/make-america-healthy-again-commission-report-childrens-health/) by a new federal advisory board, the Make America Healthy Again (MAHA) Commission chaired by Health Secretary Robert F. Kennedy Jr., calls for further investigation of pesticides’ effects to determine if their use should be limited. Some evidence does suggest that long-term exposure could lead to cancer and several other serious health problems. More research is needed to better understand these risks, but in the meantime, experts recommend simple, practical steps to reduce intake. Here’s what we know about the risks of pesticides and how to lower your exposure. ## Research on pesticide risks The MAHA report assesses “root causes” of poor health in U.S. children. It describes pesticides as one of eight types of chemicals giving rise to chronic diseases. The report specifically takes issue with two weed killers, glyphosate and atrazine. They’re the [most commonly used](https://investigatemidwest.org/2019/05/26/breaking-down-the-use-of-glyphosate-in-the-u-s-2/) pesticides by American farmers, and research has focused on them in [lab experiments](https://www.nature.com/articles/srep39328) on animals, with several concerning [findings](https://www.nature.com/articles/srep39328). Other studies have drawn links between glyphosate exposure—mainly by consuming trace amounts in food—and health problems, including [earlier death](https://www.sciencedirect.com/science/article/pii/S0147651325004324). In 2019, a large research review [identified](https://www.sciencedirect.com/science/article/abs/pii/S1383574218300887) a “compelling link” between glyphosate intake and non-Hodgkin lymphoma in humans, though in 2024 a federal judge [criticized ](https://cand.uscourts.gov/wp-content/uploads/cases-of-interest/in-re-roundup-mdl/18661-PTO-293.pdf)this study’s design and approach. Additional research [points](https://www.atsdr.cdc.gov/toxprofiles/tp214-c2.pdf) to a range of diseases potentially related to glyphosate, but a recent [review](https://www.frontiersin.org/journals/toxicology/articles/10.3389/ftox.2024.1474792/full) by Italian researchers on glyphosate was inconclusive and called for further research. **Read More**: [_Seed Oils Don't Deserve Their Bad Reputation_](https://time.com/7269715/are-seed-oils-unhealthy/) Based on the evidence, the World Health Organization (WHO) has described glyphosate as “probably carcinogenic to humans,” whereas the U.S. Environmental Protection Agency (EPA) [found](https://www.epa.gov/ingredients-used-pesticide-products/glyphosate) “no evidence that glyphosate causes cancer in humans,” citing a dataset the agency considered more thorough than WHO’s. The second [widespread](https://web.archive.org/web/20120316130312/http://www.epa.gov/teach/chem%5Fsumm/Atrazine%5Fsummary.pdf) pesticide highlighted by the MAHA report is atrazine. Like glyphosate, it’s been used by farmers since the 1960s, but research on animals in the 1990s began to show it could disrupt reproductive health and hormone regulation. Tyrone B. Hayes, a biologist at the University of California, Berkeley, found that atrazine [interfered](https://pubmed.ncbi.nlm.nih.gov/11960004/) with the sexual development of frogs. Subsequent studies showed similar effects, as well as weight gain, in [mice](https://www.publish.csiro.au/RD/RD18505). Researchers have also observed that women in certain agricultural communities experience [higher rates](https://www.sciencedirect.com/science/article/abs/pii/S0013935111002349?via%3Dihub) of abnormal menstrual cycles, compared to places with fewer farms. Other human [studies](https://www.sciencedirect.com/science/article/abs/pii/S0013935116308738?via%3Dihub) show [increases](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222984/) in [several](https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2818361) kinds of [birth defects](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4105141/). Still more [research](https://ehp.niehs.nih.gov/doi/epdf/10.1289/ehp.971051222) links atrazine to [breast](https://ehp.niehs.nih.gov/doi/10.1289/ehp.9758) cancer, but researchers at the National Institutes of Health have [concluded](https://pmc.ncbi.nlm.nih.gov/articles/PMC3230407/#:~:text=Results:%20Overall%2C%2036%2C357%20%2868%%29%20of%20applicators%20reported,higher%20exposure%20categories%20compared%20with%20the%20lowest.) “no evidence of an association” with cancer. The EPA [estimated](https://www.epa.gov/pesticides/epa-releases-draft-biological-evaluations-atrazine-simazine-and-propazine) that atrazine adversely affects 54% of all species and 50% of all critical habitats. “I don’t know how an Environmental Protection Agency can make a statement like that and then re-register the chemical,” Hayes says. In 2023, U.S. Department of Agriculture (USDA) data showed that 99% of food samples tested below the EPA’s safety limit for pesticides. However, U.S. limits are considerably higher than what’s allowed in the European Union, where atrazine has been [effectively banned](https://pubmed.ncbi.nlm.nih.gov/16967834/). **Read More**: [_The Best Longevity Habit You're Not Thinking About_](https://time.com/7265427/how-to-improve-balance-exercise/) Pesticides called organophosphates have been [studied](https://www.epa.gov/pesticides/epa-releases-updates-organophosphate-pesticides-dicrotophos-dimethoate-and#:~:text=For%20OPs%2C%20neurotoxicity%20occurring%20through%20interaction%20with,for%20its%20OP%20human%20health%20risk%20assessments.&text=Potential%20risks%20of%20concern%20for%20neurotoxicity%20were,during%20treatment%20of%20livestock%20and%20livestock%20premises.) by the EPA and others for links to [neurological disorders](https://pmc.ncbi.nlm.nih.gov/articles/PMC4458051/) such as ADHD. “Research clearly shows that children exposed to higher levels did have more neurobehavioral problems,” says Jason Richardson, professor of physiology and pharmacology at the University of Georgia’s Isakson Center for Neurological Disease Research. Overall, uncertainty and debate about pesticides continues partly due to research challenges. People are typically exposed to multiple types of chemicals, so it’s “hard to attribute disease to one pesticide or pinpoint the definitive dose or exposure time” that makes people sick, Perry says. “Just because a chemical is present doesn’t mean it’s doing anything bad, but in combination with other chemicals, it may be,” Richardson says. “Efforts are underway to measure these combinations.” “The country’s agricultural policy follows science, not fear, speculation, and fringe narratives,” says Becky Langer-Curry, director of innovation at the National Corn Growers Association. The Corn Growers were “perplexed” by the MAHA report, she adds. “We need faith in the EPA’s regulatory system to review the science. They’re ensuring our food is safe, well below human risk.” In an email to TIME.com, EPA spokesperson Mike Bastasch said the EPA“typically regulates pesticides at least 100 times lower than where no adverse effects are seen in safety studies.” The agency is “confident that the fruits and vegetables our children are eating are safer than ever,” Bastasch wrote. However, he added that the EPA is updating its evaluation of glyphosate’s cancer-causing potential, and it’s currently working on an [Updated Mitigation Proposal](https://www.epa.gov/pesticides/epa-releases-updated-mitigation-proposal-atrazine) for atrazine. In the meantime, researchers including Perry, Richardson, and Hayes think pesticides are dangerous enough that people should take precautions—but especially young kids, people who are pregnant, those who live close to farms, agricultural workers, and [seniors](https://npic.orst.edu/factsheets/olderadults.html). ## How to learn more about your exposure The first step is to become aware of pesticides in your environment. They’re more common than people think, Perry says. “Exposures happen routinely for most members of the American public.” Experts recommend contacting the environmental office of your county or city to learn whether you’re close to a food production facility that uses pesticides. In 2017, kids and teachers at a Hawaii middle school reported unusual throat irritation and dizziness. They suspected the symptoms were caused by pesticides applied in nearby fields, and researchers [found residues](https://pubmed.ncbi.nlm.nih.gov/28934654/) in the school’s indoor and outdoor air samples. **Read More**: [_What to Do If Fluoride Is Removed From Your Water_](https://time.com/7285568/what-to-do-fluoride-removed-from-water/) The detected levels were deemed below concerning thresholds. Bastasch says that, for communities near farms, the EPA studies potential exposure through the air and other pathways to make sure safety levels are based on sound science. Still, Hayes worries about the long-term effects of pesticide contact and absorption. “For someone living in a farming community that’s constantly exposed to estrogen mimics like atrazine, you’re more likely to develop adverse effects,” he says. People take in atrazine mainly through their drinking water, after farm runoff carries the pesticide into local water systems. But some utilities are more effective than others at removing pesticide residues. The [Environmental Working Group rates](https://www.ewg.org/tapwater/) local water utilities. For people on well water, the federal government provides [guidelines](https://www.cdc.gov/drinking-water/safety/guidelines-for-testing-well-water.html) for testing it. ## Use a water filter Pesticide use is widespread enough—and disperses at such distances—that everyone should probably use a high-quality water filter, experts say. Atrazine can travel as far as 600 miles, Hayes says. As far back as 1999, USGS [noticed](https://water.usgs.gov/nawqa/pnsp/pubs/wrir984245/text.html) that pesticides, including atrazine, were detected in places where farmers hadn’t applied them. Even for residents of areas where a water treatment plant removes the chemicals, buying a filter certified to the [NSF/ANSI Standards 42 and 53](https://www.nrdc.org/sites/default/files/atrazine10.pdf) provides some additional assurance of water safety. Look for filters in refrigerators and [water pitchers](https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwixsufW7sGNAxXRcEcBHRgbLswYABAIGgJxdQ&co=1&gclid=Cj0KCQjwotDBBhCQARIsAG5pinMwWR6UiXDx0rwr4IHpAn%5F8HMl8W9padTOgb5jHSmmbvo0nsVKXq6UaAg85EALw%5FwcB&ohost=www.google.com&cid=CAESV-D2TrkfFyI19VcuIJe923K7nF3euguaU0gNoH4s9vL6RySxmBy3pVCuBq6sO0JsKXOsOjsFJqqZLXHuJ7AxSCnh9aoeQYocPEsYX42ztIdY2fskSJNdKQ&category=acrcp%5Fv1%5F1&sig=AOD64%5F3t404v%5Fh1YdIPwqL295OJqwLmu-g&q&adurl&ved=2ahUKEwj7ouLW7sGNAxVXMlkFHbbUNj4Q0Qx6BAgKEAE) that meet this certification. ## Buy organic Eating organic foods can also help to reduce intake of pesticides, especially glyphosate. About 90% of pregnant women have detectable amounts of glyphosate in their bodies, according to one [study](https://ehjournal.biomedcentral.com/articles/10.1186/s12940-018-0367-0). “But when you put people on organic diets, you start to see that they no longer have pesticides in their urine,” Perry says. [Research in 2020](https://www.organic-center.org/can-organic-diet-reduce-exposure-glyphosate) found that eating an organic diet dropped glyphosate levels by 70% in children and their parents. In 2023, researchers put pregnant women on an organic diet for one week. Those who went all-organic [decreased](https://ehp.niehs.nih.gov/doi/pdf/10.1289/EHP12155) glyphosate in their urine by 43%. A [2019 study](https://www.sciencedirect.com/science/article/pii/S0013935119300246) found a 95% reduction in organophosphates. ## Wash and peel Richardson calls these studies on organic foods “intriguing” while noting that natural compounds used in organic farming may also be [toxic](https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/rotenone#:~:text=Rotenone%20toxicity%20has%20been%20studied,referred%20to%20Gupta%20%282012%29.) beyond certain thresholds. Even when eating organic, “make sure you wash your fruits and vegetables very well,” he says. **Read More**: [_Dermatologists Have a Dirty Little Secret_](https://time.com/7262592/best-soap-shower-dermatologists/) One [study](https://pubmed.ncbi.nlm.nih.gov/29067814/) found that soaking apples in baking soda mixed with water for 12-15 minutes eliminated more residue than water alone. However, according to another [study](https://pmc.ncbi.nlm.nih.gov/articles/PMC9498324/), washing produce with running water is superior to baking soda, sitting water, and vinegar. Other research shows a gentle [rubbing action](https://www.epa.gov/safepestcontrol/pesticides-and-food-healthy-sensible-food-practices) during washing is [effective](https://pmc.ncbi.nlm.nih.gov/articles/PMC11643934/). Aim for [20-30 seconds](https://middletownct.gov/DocumentCenter/View/23556/GMAHEC-Washing-Fruits-and-Veggies) or [longer if you have time](https://pmc.ncbi.nlm.nih.gov/articles/PMC4688301/). Peeling the skin and outer pulp will get rid of additional residue that penetrates into some produce. There’s a major downside, though: you lose a portion of the beneficial nutrients and compounds, like fiber and vitamins, that help protect against pesticide toxicity. Some research suggests that replacing [processed foods](https://www.organic-center.org/can-organic-diet-reduce-exposure-glyphosate) with [diverse whole foods](https://www.sciencedirect.com/science/article/abs/pii/S004896972207036X) can reduce how many pesticides you ingest (but some research suggests there may be [fewer benefits](https://ajcn.nutrition.org/article/S0002-9165%2822%2900146-0/pdf) if they’re not organic). ## Exercise and manage stress Aside from nutrition, other lifestyle behaviors such as exercise, stress management, and good sleep may build a baseline of health that helps thwart the cumulative effects of pesticides and other pollutants. Overall, they influence how someone’s body responds to their “[exposome](https://factor.niehs.nih.gov/2023/3/community-impact/niehs-council-meeting),” Richardson explains—your total environmental exposures and how they interact with lifestyle behaviors and risk factors like age and [genetics](https://www.uclahealth.org/news/release/genetic-variations-may-predispose-people-parkinsons-disease#:~:text=Neurology-,Genetic%20variations%20may%20predispose%20people%20to%20Parkinson's%20disease%20following,term%20pesticide%20exposure%2C%20study%20finds&text=A%20new%20UCLA%20Health%20study,the%20risk%20of%20Parkinson's%20disease.). Bastasch says the EPA assesses the combined risks of groups of pesticides that affect the body in similar ways, adding that the agency is continuing to advance research in this area. The exposome probably matters more than any one chemical type, but “we’re really just breaking the surface of understanding these interactions,” Richardson says. Until more definitive science emerges, maintain smart practices like scrubbing produce and striving for a healthy lifestyle. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/7291075/are-pesticides-dangerous-maha-glyphosate-atrazine/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/7291075/are-pesticides-dangerous-maha-glyphosate-atrazine/"},"headline":"Are Pesticides in Your Food Harmful?","datePublished":"2025-06-05T15:42:48.000Z","dateModified":"2026-03-11T00:46:06.550Z","description":"Here’s what we know about the risks of glyphosate, atrazine, and other pesticides—and how to lower your exposure.","url":"https://time.com/7291075/are-pesticides-dangerous-maha-glyphosate-atrazine/","keywords":["Public Health","freelance","healthscienceclimate"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt3109e227f7c2aaf9/6998c7227323af96392bc90a/tractor-pesticides.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Matt Fuchs","jobTitle":"Matt Fuchs writes about science, health, aging, and well-being.
