Until long-term clinical trials are completed, the published observational studies provide the best evidence in support of eating organic. All categories are weighted equally, since they convey different but equally relevant information about pesticide levels on produce. That means a lot of harmful chemicals have been used in the process of growth. One study of olives and olive oils using organic pesticides found increased levels of the biopesticides rotenone, azadirachtin, pyrethrin and copper fungicides ( 24 ). According to the US Environmental Protection Agency (EPA), a pesticide is a broad term that includes insecticides, fungicides, herbicides, and any other (biological or chemical) substance that is used to control pests, which may include insects, weeds, plants, rodents, and microorganisms. Vigar, V., et al., A Systematic Review of Organic Versus Conventional Food Consumption: Is There a Measurable Benefit on Human Health? Notably, it does not analyze glyphosate, or Roundup, the most heavily used pesticide in the U.S., but high levels can be found in several grains and beans, such as oats and chickpeas, due to its increasing use as a pre-harvest drying agent. Spinach: 97% of … Plus, with the assistance of natural wind, pesticides also contaminate the air and water. Journal of Exposure Science and Environmental Epidemiology, 2018; 28, 31-39. Downie, David (2003). “Global POPs Policy: The 2001 Stockholm Convention on Persistent Organic Pollutants”, in D. Downie and T. Fenge (ed.) Beef, Pork and Poultry The EPA reports that meat is contaminated with higher levels of pesticides than any plant food. Toxicology letters,127(1), 29-41. Almost 70 percent of Clean Fifteen fruit and vegetable samples had no pesticide residues. Before testing, the USDA processes each fruit or vegetable in the same way that people tend to do at home. Key findings: These 15 items had the lowest amounts of pesticide residues, according to EWG’s analysis of the most recent USDA data.1 Key findings: Eating organic food reduces pesticide exposure and is linked to a variety of health benefits, according to an article published this year in the peer-reviewed journal Nutrients.2 In four separate clinical trials, people who switched from conventional to organic foods saw a rapid and dramatic reduction in their urinary pesticide concentrations, a marker of pesticide exposure. Almost 70% of these samples had no pesticide residues whatsoever: Avocados Sweet corn Pineapple Onions Papaya Sweet Peas (Frozen) Eggplant Asparagus Cauliflower Cantaloupes Broccoli Mushrooms Cabbage Honeydew Melon Kiwi Kale samples detected 18 different pesticides. EWG’s standard criteria do not rank peppers among the Dirty Dozen, but because they test positive for pesticides known to be toxic to the brain, we’ve included them in the Dirty Dozen Plus™ list. Ratings for more than 120,000 food and personal care products, now at your fingertips. Five Lesser Known Foods High in Pesticides: The Answer May Surprise You 1. Latest News. Whether organic or conventionally grown, fruits and vegetables are critical components of a healthy diet. Nearly 70 percent of the fresh produce sold in the U.S. contains residues of potentially harmful chemical pesticides, according to EWG’s analysis of the latest test data from the federal Department of Agriculture. Learn which foods are the highest in pesticide residues. More than 90 percent of samples of strawberries, apples, cherries, spinach, nectarines, and kale tested positive for residues of two or more pesticides. Currently, biological pesticides that are based on natural substances or pheromone-based pesticides are preferred over conventional chemical pesticides, as these natural pesticides are considered safer and more environmentally-friendly. Dietary pesticides (99.99% all natural). To compare foods, EWG looked at six measures of pesticide contamination: Within each of these categories, we ranked the 47 fruits and vegetables and then normalized the ranks on a scale of 1 to 100, with 100 being the highest. As with last year’s Shopper’s Guide, kale ranks third on the 2020 Dirty Dozen list. Moreover, it is advisable to have a variety of food items on your menu, especially organic food and vegetables, which come from diverse sources. Ratings for more than 120,000 food and personal care products, now at your fingertips. According to the Environmental Working Group (EWG), the twelve foods that contain the most pesticides include Apples, Strawberries, Grapes, Celery, Peaches, Spinach, Sweet bell peppers, Nectarines (imported), Cucumbers, Cherry tomatoes, Snap peas (imported), and Potatoes. Environmental Working Group is a 501(c)(3) nonprofit corporation, EIN 52-2148600. Proceedings of the National Academy of Sciences, 87(19), 7777-7781. Corn syrup and corn oil, produced from predominantly GMO starchy field corn, are commonly found in processed foods. The FQPA safety standard isn’t the only reason why EPA has been able to take so many steps to reduce children’s exposure to pesticides in recent years. EWG provides several resources – including EWG’s Shopper’s Guide To Avoiding GMO Food, the Food Scores database and EWG’s Healthy Living app – to help consumers identify foods likely to contain genetically engineered ingredients. Food Research International, 2009; 42:26-40. Maximum number of pesticides found on a single sample. But because the USDA tested raisins last year for the first time since 2007, we decided to see how they would fare on the Dirty Dozen™, our annual ranking of the fruits and vegetables with the most pesticides. However, based on the final rule, released in 2018 by the Trump Administration, these labels may be difficult to interpret, with confusing terms like “bioengineered.” Until the law takes effect, consumers who want to avoid GMOs may choose organic zucchini, yellow squash, sweet corn, papaya, apples and potatoes. Legal Disclaimer | Ranked from highest pesticide contamination to lowest, here were the top fruits and vegetables: Green, yellow and red peppers (6) Spinach (6) Strawberries (6) Spinach. Copyright © 2020. Researchers from Harvard University used USDA test data and methods similar to ours to classify produce as having high or low pesticides.4 Remarkably, their lists of high and low pesticide crops largely overlap with our Dirty Dozen and Clean Fifteen. According to the Environmental Working Group (EWG), the twelve foods that contain the most pesticides include Apples, Strawberries, Grapes, Celery, Peaches, Spinach, Sweet bell peppers, Nectarines (imported), Cucumbers, Cherry tomatoes, Snap peas (imported), and Potatoes. Therefore, the USDA test results are a good indication of consumers’ likely exposure. The chief responsibility of deciding which pesticides are approved for use in the U.S., including deciding what conditions are placed on their approval and setting the pesticide residue levels on foods and crops, falls to the EPA. They are commonly used to protect plants, including the fruits and vegetables that we eat. EWG recommends that consumers choose organic peppers in lieu of conventionally grown. DOI: https://doi.org/10.1038/jes.2017.22. The California Department of Pesticide Regulation (DPR) states that only about 1 in 100 sample foods tested in California were found to have pesticide levels that were considered illegal or over the maximum permissible values. Despite testing foods for more than … Organic vs. conventional agriculture: knowledge, power and innovation in the food chain. DOI: 10.1001/amainternmed.2017.5038. Download EWG’s Healthy Living App Today! 6 Disgusting Things That Will Make You Switch to Organic Produce Each year the USDA selects a subset of these fruits and vegetables to test, rather than testing each crop each year. Available at: https://www.nature.com/articles/jes201722, Gaskins A.J., et al. On average, kale and spinach samples had 1.1 to 1.8 times as much pesticide residue by weight than any other crop tested. Average number of pesticides found on a single sample. Pesticides are not directly used on these foods, but the grains that the animals eat are often sprayed with pesticides. Since pesticide contamination varies by crop, it is important to understand which items are most or least contaminated. Most effects from pesticides are felt at high exposure levels, and are no reason to give up on fruits and vegetables completely. Agricultural Marketing Service. In these cases, we displayed domestic and imported items separately to help you select the option with the lowest pesticide levels. Available at https://pediatrics.aappublications.org/content/130/5/e1406, Kaushik, G., et al., Food processing a tool to pesticide residue dissipation – A review. But the dirtiest produce commodity, according to the USDA’s Pesticide Data Program, is not a fresh fruit or vegetable but a dried one – raisins. This article was adapted and updated from the 2019 Shopper’s Guide. An EWG investigation published this year found that for most pesticides, the Environmental Protection Agency does not apply additional restrictions to safeguard children’s health. Doi: 10.1016/j.ajog.2019.02.004, American Academy of Pediatrics, Organic Foods: Health and Environmental Advantages and Disadvantages. Sweet Corn. December 8, 2020. The Environmental Working Group (EWG - an organization of scientists, researchers and policymakers), based on research conducted by USDA, has compiled a list of popular 50 plant foods that rate them based on the amount of pesticides, from high to low. Donate $10 today and EWG will send you our Shopper's Guide to Pesticides in Produce™ wallet guide FREE to say thank you. EWG’s Shopper’s Guide To Avoiding GMO Food, Health Benefits of Reducing Dietary Pesticide Exposure, Apples, apple sauces, blueberries, grapes, green beans, leafy greens, pears, peaches, potatoes, plums, spinach, strawberries, raisins, sweet peppers, tomatoes, winter squashes, Apple juice, avocados, bananas, beans, broccoli, cabbages, cantaloupes, carrots, cauliflower, celery, corn, eggplants, grapefruits, lentils, lettuce, onions, oranges, orange juices, peas, prunes, summer squashes, sweet potatoes, tofu, tomato sauces, zucchini. The application of pesticides (insecticides, herbicides, fungicides etc.) From these studies, it is unclear whether the positive effects associated with organic foods are directly and exclusively caused by lower pesticide exposures. For example, items with inedible peels are peeled, and those with edible peels are rinsed under cold water and drained before testing. These are examples of the potential undermining of marketplace safety, since products with harmful health concerns can remain on the market. However, low levels of pesticide residues may still remain on some foods… Less than 2% of sampled sweet corn … However, you may find genetically modified zucchini, yellow squash, sweet corn, papaya and apples in U.S. markets, though only papayas are predominantly GMO. Dietary intake estimations of organohalogen contaminants (dioxins, PCB, PBDE and chlorinated pesticides, eg DDT) based on Swedish market basket data. Apart from the EPA that regulates pesticide levels in foods, each state has departments that control such contamination parameters. In an ideal world, we would all buy certified organic food 100% of the time. DOI: https://doi.org/10.3390/nu12010007. Although the use of pesticides allows farmers to grow these foods more efficiently, these chemicals have been shown to cause health problems in humans, including disruption of the endocrine system and reproductive health (1), respiratory symptoms (2), cancer (3), and neuro-degeneration leading to Alz… JAMA Internal Medicine, 2018. Unprocessed produce tends to have higher concentrations of pesticides, as shown by testing by the California Department of Pesticide Regulation. Genetically engineered crops, or GMOs, are most commonly found in processed foods rather than in fresh produce. Natural does not mean safe. Northern Lights against POPs: Combating Toxic Threats in the Arctic, Montreal: McGill-Queens University Press. USDA, Pesticide Data Program. Cherry tomatoes are among the highest pesticide-containing foods unless you grow your own crop; buy from an organic-certified farmer, or an organic-certified grocery store. 2. People who consume higher amounts of organic produce tend to be more health-conscious in general, making it difficult to determine the exact cause of an observed health outcome. Pesticide applications to crops result in varying levels of residues remaining in, or on, our food. Only 7 percent of Clean Fifteen fruit and vegetable samples had two or more pesticides. NOTE: As all Americans struggle to adapt to the reality of daily life during the spread of the coronavirus pandemic, it is important to know that there is no evidence people can be exposed through food. Also important to note is that the USDA does not test for all pesticides used in crop production. That is why, even though the risks of COVID-19 are serious, consumers should continue to eat plenty of healthy fruits and vegetables, whether they are conventional or organic. However, all food and food products sold in US are bound by the same set of laws, rules, and safety standards. While the 2019 list doesn't differ much from last year's, there is a new and popular addition that cracks the top three: kale. Privacy Policy | The Shopper's Guide full list shows how fruits and vegetables rank based on these total scores. "We were surprised kale had so many pesticides on it, but the test results were unequivocal," EWG Toxicologist Alexis Temkin, PhD, stated in a press release. The EWG released their annual report of the "dirty dozen," which is a list of which produce you commonly eat that's loaded down with the most pesticides. These researchers also found that people who consumed greater quantities of crops high in pesticides had higher levels of urinary pesticides and lower fertility.4,5 Alternatively, people who consumed a pro-fertility diet, which included the low pesticide crops, among other foods and nutrients, like whole grains and folic acid, were more likely to have a successful pregnancy.6. The Dirty Dozen PLUS™ list includes sweet bell peppers and hot peppers, both of which can... 2. Available at: https://www.mdpi.com/2072-6643/12/1/7/htm. Darnerud, P. O., Atuma, S., Aune, M., Bjerselius, R., Glynn, A., Grawé, K. P., & Becker, W. (2006). Pesticides play an important role in making sure there is enough food for everyone, by protecting food and crops from pests. [1] All foods contain pesticides, and 99.99% of the pesticides you are exposed to are all natural. All pesticides are weighted equally, and we do not factor in the levels deemed acceptable by the EPA. While pesticides help protect our food supply, many people are concerned about pesticides on the food they eat. All Rights Reserved. There were found to be pesticide residues in over 90% of apple samples. When the USDA tested 360 ... 2. EWG designed this method to capture this uncertainty and enable consumers to reduce their overall pesticide load. Fewer than 2 percent of samples showed any detectable pesticides. More than 90 percent of samples of strawberries, apples, cherries, spinach, nectarines, and kale tested positive for residues of two or more pesticides. With the exception of cabbage, all other products on the Clean Fifteen tested positive for four or fewer pesticides. In 1991 the USDA initiated the Pesticide Data Program and began testing commodities annually for pesticide residues, but we continue to be concerned about pesticide regulation in the U.S. Strawberries. In nature, pesticides are impossible to limit to specific areas, since sprays often venture into unintentional areas. Pesticides are chemicals that destroy pests. The international environmental treaty ‘Stockholm Convention on Persistent Organic Pollutants’, that is in implementation since 2004, aims to restrict, phase out, and completely eliminate the use of persistent organic pollutants (POPs). In the U.S, pesticide regulation, monitoring and enforcement is scattered across multiple federal and state agencies. The Environmental Protection Agency classifies DCPA as a possible human carcinogen, and in 2009 the European Union banned it. The Shopper’s Guide ranks pesticide contamination on 47 popular fruits and vegetables based on an analysis of more than 43,700 samples taken by the USDA and the FDA. American Journal of Obstetrics and Gynecology, 2019; 220:567.e1-18. Of the 47 items included in our analysis, these Dirty Dozen foods were contaminated with more pesticides than other crops, according to our analysis of USDA data.1 (The rankings are based not only on the percentage of samples with pesticides but also on the number and amount of pesticides on all samples and on individual samples. Despite testing foods for more than 500 pesticides, the USDA tests do not include glyphosate, the most widely used pesticide in the U.S. Research by EWG and other advocacy groups has highlighted the pervasive contamination of our food supply with glyphosate, a chemical associated with … This healthy, fatty fruit scored the number one spot for the least pesticide-contaminated produce item ( 6 ). Fish and seafood may also contain traces of pesticides if they are farmed or grown in areas where the water is contaminated by pesticides. The primary pesticide law – the Federal Insecticide, Fungicide, and Rodenticide Act, or FIFRA – is far less health protective than the laws that protect the safety of our air, food, water and environment. But primary enforcement authority for pesticide use on farms is left to states, and the responsibility of testing foods to determine dietary exposures to pesticides is divided between the USDA and the Food and Drug Administration. Multiple pesticide residues are extremely rare on Clean Fifteen vegetables. The 2019 report shows that over 90 percent of strawberry samples tested positive for residues of two or more pesticides. Between 2010 and 2012, USDA tests found peppers contained acephate, chlorpyrifos and oxamyl – toxic insecticides that are banned from use on some crops but still permitted on hot peppers. However, the EPA does not conduct its own independent testing of pesticides. Yet, as the EWG study found, this tenfold margin of safety was not included in the EPA’s allowable limits for almost 90 percent of the most common pesticides. Morgan, K., & Murdoch, J. Five Foods High in Pesticides. Environmental Health Perspectives, 2019; 127(10). Besides, it is not always true that consuming the dirty dozen foods that have above permitted pesticide levels (or maximum residual limits) may imply severe health risk, since there is a margin of safety included. Papadopoulou, E., et al., Diet as a Source of Exposure to Environmental Contaminants for Pregnant Women and Children from Six European Countries. However, many crops contain potentially harmful pesticides, even after washing, peeling or scrubbing, which the USDA does before testing each item. Pesticides in our Food. There are many reasons EWG fights for pesticide regulation and reform: registration loopholes, limited public participation, outdated registration and pesticide registration backlogs, to name a few. Also, the amount of chemicals you may be exposed to through pesticides may be contained to a greater degree if all fruits and vegetables consumed are washed thoroughly and then peeled and trimmed. Environmental Working Group. Food and chemical toxicology, 44(9), 1597-1606. According to the EWG, the following conventional fruits and vegetables have the highest levels of pesticide residues ( 5 ): Strawberries: Conventional strawberries consistently top the Dirty Dozen list. "By the time food reaches your grocery store, pesticide residues are generally far below the legal limits. Comparison of questionnaire-based estimation of pesticide residue intake from fruits and vegetables with urinary concentrations of pesticide biomarkers. Not all pesticides registered under FIFRA adequately protect human health and the environment, and federal food tolerance residue levels often allow for higher exposure levels than public health advocates, including EWG, consider to be safe. Since the USDA doesn’t test honeydew melons, EWG uses the FDA’s pesticide monitoring data for this crop. The pesticide registration process requires companies to submit safety data, proposed uses and product labels to be approved by the EPA. Yet there are some commodities that are not tested annually, including baby food (last tested in 2013), oats (last tested in 2014), and baby formula (last tested in 2014). In the US, the EPA controls, regulates, and sets limits on pesticide tolerances on food and food products. There are few dishes that aren't enhanced by the sweet bell pepper, but even fewer foods that have as high a probability of carrying pesticides. Since its inception in 1991, the annual PDP report has tested 109 items for pesticide levels, including produce, grains, meat and poultry products. In 2012, the American Academy of Pediatrics issued an important report that said children have “unique susceptibilities to [pesticide residues’] potential toxicity.” The academy cited research that linked pesticide exposures in early life to pediatric cancers, decreased cognitive function and behavioral problems. The biggest problem with these types of products is that they can be high in pesticides. Percent of samples with two or more detectable pesticides. Eliminating high-histamine foods from your diet and then adding them back one at a time will give you an idea of what foods your body can tolerate and which foods … Alternatively, if organic peppers are unavailable or too expensive, EWG suggests that you cook conventionally grown peppers before eating them, as heating food can reduce pesticide levels.8. Among the 12 most dangerous POPs listed, 9 of them are pesticides. But so far, the clinical trials for organic foods have been short-term studies spanning days to months, although health benefits from eating organic foods may take much longer to become evident. Clinical trials – in which participants are monitored before and after switching to an organic diet – may be better able to identify cause-and-effect links between diet and outcomes. Available at: www.ams.usda.gov/datasets/pdp. This is concerning, because scientists have found that the combination of two or more pesticides can be more potent than the use of the pesticides individually. Percent of samples tested with detectable pesticides. More than 90 percent of samples of strawberries, apples, cherries, spinach, nectarines, and kale tested positive for residues of two or more pesticides. Spinach. Nutrients, 2020; 12(1), 7. Hot and sweet bell peppers. Food contamination by metals and pesticides in the European Union. Shopper’s Guide to Pesticides in Produce™, increasing use as a pre-harvest drying agent. Should we worry?. Updated: Strawberries. The landmark 1996 Food Quality Protection Act required the EPA to protect children’s health by applying an extra margin of safety to legal limits for pesticides in food. Available at: http://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2659557, Chiu, Y.H., et al. Continuous and chronic exposure to pesticides may result in several cancer types (affecting the skin, blood, kidney, liver, prostate, pancreas, and brain), birth defects and stillbirths, infertility, neurological disorders, and neurological developmental issues. Study: Nitrate in Wisconsin’s Drinking Water Linked to Cancer, Preterm Births and Up To $74 Million in Yearly Healthcare Costs. Total number of pesticides found on the crop. 1. However, neither the USDA nor the FDA regularly test all commodities for pesticide residues, nor do the programs test for all pesticides commonly used in agriculture. This 24th Pesticide Data Program summary presents results for samples collected in 2014. Geoforum, 31(2), 159-173. The USDA test program includes both domestically grown and imported produce, and sometimes ranks differ on the basis of origin. EWG helps protect your family from pesticides! Almost every sample of non-organic raisins tested – 99 percent – had residues of at least two pesticides. Ames, B. N., Profet, M., & Gold, L. S. (1990).
