These 12 Fruits and Vegetables Have the Most Pesticides — Does Your Family Eat Them?
The advocacy and watchdog organization Environmental Working Group has released its annual 'Dirty Dozen' list of the produce items with the highest levels of pesticides
Topping the list is spinach, which EWG says includes a pesticide that's banned in Europe
Potatoes were also found to have a pesticide that's banned in EuropeAn annual list of of produce items with high levels of pesticides says leafy greens and fruit are loaded with toxins — including some that are banned in Europe.
Dubbed the 'Dirty Dozen,' twelve popular produce items were found to contain high levels of pesticides and fungicides, according to a new report from nonprofit activist and watchdog group, Environmental Working Group. Topping the list was spinach; EWG's report says they found an average of seven pesticides on the leafy greens sampled, and 76% of the samples contained permethrin, which was banned in Europe in 2002.
As the U.S. Environmental Protection Agency says, it's 'classified permethrin as 'Likely to be Carcinogenic to Humans' by the oral route' and is restricted to use on crops and farms only.
Rounding out the list were strawberries, kale (and mustard greens and collards), grapes, peaches, cherries, nectarines, pears, apples, blackberries, blueberries and potatoes.
The spuds also include a pesticide that's banned in Europe, chlorpropham, which the EPA says is used to 'inhibit sprouting in stored potatoes.'
The research was conducted using data from the 53,692 samples of 47 fruits and vegetables from the USDA, and found that 75% of the non-organic samples contained pesticides. Blackberries made the list for the first time, with EWG saying one sample had 14 different pesticide residues.
The advocacy group's vice president of science, Alexis Temkin, told CNN, 'The guide is there to help consumers eat a lot of fruits and vegetables while trying to reduce pesticide exposure … One of the things that a lot of peer-reviewed studies have shown over and over again [is] that when people switch to an organic diet from a conventional diet, you can really see measurable levels in the reduction of pesticide levels in the urine.'
The group also releases a list of the 'Clean Fifteen' — aka, the produce items with the lowest amount of pesticides. These include pineapples, sweet corn (both fresh and frozen), avocados, papaya, onions, frozen sweet peas, asparagus, cabbage, watermelon, cauliflower, bananas, mangos, carrots, mushrooms and kiwis.
Most of these produce items do not have an edible skin, which is a common thread with the fruit and vegetables that the group says have high pesticide levels.
The Alliance for Food and Farming's executive director, Teresa Thorne, told CNN, 'consumers should be reassured by decades of toxicology studies, government data and nutrition research which underscores the importance of a diet rich in fruits and vegetables on health and the safety of both organic and conventionally grown produce.'

RFK Jr.'s new vaccine advisers include ER doctor who posted Islamophobic commentary online, expert witnesses against vaccines
Among the eight people who Robert F. Kennedy Jr. announced would make up his new group of outside vaccine advisers to the US Centers for Disease Control and Prevention are an emergency physician who posted Islamophobic commentary on social media and two doctors who were paid to provide expert testimony in trials against a vaccine maker. Kennedy, who was himself an influential anti-vaccine advocate before taking the helm at the US Department of Health and Human Services this year, dismissed the previous 17-member Advisory Committee on Immunization Practices, or ACIP, saying the group was 'plagued with conflicts of interest.' He pledged that their replacements wouldn't be 'ideological anti-vaxxers.' Some, though, have been accused of spreading false or misleading information about the safety of vaccines. Among the new members is Dr. Vicky Pebsworth, who holds a Ph.D. in nursing and public health, and who serves as volunteer director of research and patient safety for the National Vaccine Information Center, which advocates for vaccine exemptions and has argued that mRNA Covid-19 vaccines should not be recommended for anyone. Dr. Retsef Levi, a professor of operations research at MIT, has a 2023 post pinned to the top of his account on X that says, 'The evidence is mounting and indisputable that MRNA vaccines cause serious harm including death, especially among young people. We have to stop giving them immediately!' despite studies showing that they are safe and effective and research showing that they have saved millions of lives. Dr. Robert Malone, an early researcher of mRNA technology, has suggested that Covid-19 vaccines may cause cancer, something regulatory agencies say is not the case. Malone also served as a paid expert witness in an antitrust lawsuit over Merck's measles, mumps and rubella vaccine, testifying that plaintiffs compensated him at a rate of $350 per hour. Malone noted at the time that his compensation did 'not depend on the outcome of this litigation or my conclusions.' Fellow new ACIP member Dr. Martin Kulldorff, who has called vaccines 'vital,' served as a paid witness in a vaccine trial against Merck over the safety of its HPV vaccine, Gardasil. The committee's conflict-of-interest policy says members of its work groups 'should agree that they will not serve as a paid litigation consultant or expert witness in litigation involving a vaccine or manufacturer under the purview of the [work group].' Dorit Reiss, a professor of law at UC Law San Francisco, noted that 'past expert witness work may not be a bar, but that's true of the [conflicts of interest] Kennedy used to justify dismissing' the previous members. Kulldorff did not respond to requests for comment about his testimony and whether he would recuse himself from discussions related to Gardasil. Malone also didn't respond to CNN's request for comment. An HHS spokesperson told CNN that the agency 'takes conflicts of interest very seriously' and will 'make sure anyone participating in the meetings do not have any conflicts of interest in the agenda they'll be meeting on.' Several of the new appointees have been in Kennedy's orbit for years. He dedicated his 2021 book, 'The Real Anthony Fauci,' to the 'battle-hardened cadre of heroic scientists and physicians' who fought Fauci's pandemic strategies, including Kulldorff and Malone. He also listed Pebsworth on a 'heroic healers honor roll.' Others are less well-known. Emergency physician Dr. James Pagano doesn't appear to have shared his vaccine views publicly. An X account bearing his name most recently includes supportive replies to posts about President Donald Trump, Elon Musk and Kennedy. About 10 years ago, Pagano posted on the account, 'What's wrong with being an islamophobe? There's so much there not to like.' Pagano didn't respond to CNN's request for comment. A spokesperson for HHS told CNN, 'This was a tongue-in-cheek post made ten years ago that was a reference to the news cycle at the time. It has nothing to do with his qualifications' to serve on ACIP. Pagano is a 'highly qualified medical doctor that will take these issues very seriously.' Caleb Kieffer, a senior research analyst for the Intelligence Project at the Southern Poverty Law Center, called the post 'concerning and problematic, whether it's kind of a one-off or not. … Islamophobia is a recognized form of bigotry. It was a recognized form of bigotry when this was posted in 2015, and it remains a recognized form of bigotry and problem today.' The committee is scheduled to meet June 25 to discuss vaccines for Covid-19, cytomegalovirus, HPV, flu and other diseases. According to the Federal Register, recommendation votes are scheduled for multiple vaccines, including for the Vaccines for Children program, which provides vaccines at no cost to those whose parents or guardians may not be able to afford them. An HHS spokesperson said the new members' ethics agreements will be made public before they start. 'Every ACIP member will be vetted in accordance with their ethics agreement before they are permitted to participate in each meeting agenda item,' HHS Director of Communications Andrew Nixon said in a statement. 'Secretary Kennedy has replaced vaccine groupthink with a diversity of viewpoints on ACIP.' Here's a look at all the new committee members. Hibbeln is a former NIH researcher focused on nutrition and psychiatry, with a particular interest in seafood: He is an unpaid adviser to Positively Groundfish, a nonprofit trade association supporting the fishing industry. Though his vaccine views haven't been made clear, a paper he co-authored in 2018 notes that a connection between a form of mercury in vaccines, thimerosal, and autism 'has been largely repudiated.' Kennedy noted in his X post that, while at the NIH, Hibbeln 'led research on immune regulation, neurodevelopment, and mental health' and that his work has 'informed US public health guidelines, particularly in maternal and child health.' Hibbeln declined to comment when reached by email. Kulldorff was a prominent early critic of the US government's coronavirus response, namely broad shutdowns and school closures, and later the Covid-19 vaccines and what he has argued was federal collusion with social media companies to censor his and others' views. The Swedish epidemiologist and biostatistician teamed up with Oxford professor Dr. Sunetra Gupta and Stanford professor Dr. Jay Bhattacharya, now director of the National Institutes of Health, to write the October 2020 'Great Barrington Declaration,' which argued for fewer social distancing requirements for young, healthy people rather than broad lockdowns. That alliance carried on as Bhattacharya assumed his federal role. Kulldorff's name swirled in the early days of the second Trump administration as HHS officials discussed potential hires around the agencies and appointments to advisory panels, according to a personal familiar with the discussions who asked to remain anonymous because they were not authorized to speak with CNN. Kennedy also seemed to suggest in April that Kulldorff was part of the agency's effort to research the causes of autism. 'This is all being run by Jay Bhattacharya and by, I think, Martin Kulldorff, maybe also working on this, on designing the grant proposals,' Kennedy said April 16. Asked by reporters a few days later about Kulldorff's level of involvement in the autism initiative, Bhattacharya declined to discuss 'any personnel decisions specifically' but added that 'this is public knowledge. I'm very close friends with Martin, and we talk all the time.' Kulldorff wrote in a commentary in the urban policy magazine City Journal that 'vaccines are a vital medical invention' but that clinical trials for Covid-19 shots were not properly designed. He also said he has 'spent decades studying drug and vaccine adverse reactions without taking any money from pharmaceutical companies.' Levi is a professor of operations management at MIT and trained as a mathematician. His bio on the MIT website says he studies food supply chains. He also spent nearly 12 years as an intelligence officer in the Israeli Defense Forces. In an email to CNN, Levi said that he has nearly '19 years of extensive work with healthcare systems and health data,' including 'work on quality and safety of manufacturing of biologic drugs, post marketing safety signal detection, epidemiological models and more generally data driven and statistical/AI enabled frameworks and decision support tools to manage and optimize risk-benefit tradeoffs.' 'I also have been conducting research specifically on the COVID-19 vaccines,' he wrote. In 2022, Levi co-authored a study that looked at the relationship between Covid-19 vaccination rates in Israel and emergency calls for heart problems in teens and young adults. Levi and his co-authors reported a 25% increase in these heart-related emergencies in the early months of 2021 compared with 2019 through 2020. They concluded that this increase was not due to a wave of Covid-19 illnesses — which can cause heart problems — but instead was associated with the timing of the first and second doses of mRNA vaccines in this age group. Observational studies like this one can be misleading because while they may show that two things happen at the same time, they can't prove that one caused the other. In order to prove that vaccines caused an increase in heart-related emergencies in Israel, the researchers would have needed to know the vaccination status of patients in the study and to show that heart-related emergencies increased in vaccinated compared with unvaccinated individuals. The study authors didn't have that information, according to an independent fact check of the study's claims. More recently, Levi has co-authored a study with Florida's surgeon general, Dr. Joseph Ladapo, who in 2024 called for a halt in the use of the Covid-19 vaccine in the state, even for adults over age 65. This new study, which was posted as a preprint — meaning it hadn't been scrutinized by outside experts or published in medical journal — compared death risks in 1.4 million Florida adults who received either the Pfizer or Moderna Covid vaccines in the year after vaccination. The study authors say that they found a higher risk of dying from any cause, and from heart-related causes, in Floridians who received Pfizer's Covid-19 vaccines than in those who received shots from Moderna and that this indicates the vaccines have different 'non-specific' effects. In an email, Levi said that nonspecific effects relate to 'health outcomes broader than and beyond the target virus,' such as deaths from any cause or heart-related deaths. But the study didn't compare death rates in the vaccinated groups with those in people who were unvaccinated. Other studies have found that Covid-19 contributed to excess deaths during the years of the pandemic and to heart-related deaths specifically. The study also didn't account for different dosages in the Pfizer and Moderna vaccines, noted Dr. Peter Hotez, a pediatrician and infectious disease expert who is co-director of the Center for Vaccine Development at Texas Children's Hospital. Moderna's shots had a higher dose of mRNA than Pfizer's: 100 micrograms vs. about 30 micrograms. If the excess deaths were caused by Covid, greater protection from the Moderna vaccines might explain the higher death risk in the Pfizer-vaccinated group, Hotez said. When asked whether the different dosing of mRNA in the vaccines might account for the findings, Levi wrote, 'I think that the hypothesis that Moderna has protective effects against non-COVID deaths and even against cardiovascular deaths, while cannot be fully dismissed, is highly implausible, and not supported by evidence.' In fact, Hotez said, it is supported by evidence. Hotez said in an email that this kind of messaging 'cherry picks a weakly supported factoid, and blows it up until it defies reality but supports their false narrative, while simultaneously ignoring a mountain of counter evidence.' The study authors used the findings to try to sow doubt about the vaccines. In a social media post, Ladapo wrote, 'Did your doctor tell you that you might be more likely to die if you took Pfizer instead of Moderna? That's what we found in Florida, and other studies have shown similar results. The system is rotten and we need more honest scientists.' Although Malone made some key early innovations in mRNA and its potential use in drug therapies, the biochemist has argued in recent years that mRNA-based Covid-19 vaccines are risky and that drug regulators too rapidly authorized their use. In 2023, Malone told House representatives during an event on Covid-19 vaccine injury led by Georgia Republican Marjorie Taylor Greene that he believes mRNA shots can cause cancer, a claim that is not backed by peer-reviewed scientific literature and the FDAand the National Cancer Institute say there is no evidence of a link. Malone's criticisms extend beyond mRNA immunizations. In April, he suggested that a number of measles cases in the current outbreak were caused by the vaccines themselves – although the CDC says they are rare breakthrough cases due to community spread, not cases from shots. In December, he wrote that early polio shots caused cancer because of contamination with the simian 40 virus. The CDC has said that although that virus has caused cancer in some animals, there is no evidence that it caused human cancers. More recently, Malone served as a senior medical adviser to Independent Medical Alliance, formerly known as the Frontline COVID-19 Critical Care Alliance, a nonprofit that pushed back on vaccine requirements and touted unproven coronavirus treatments such as ivermectin. The group celebrated Malone's appointment to the panel Wednesday. Asked whether it had any input with HHS on the new ACIP members, IMA President and Chief Medical Officer Dr. Joseph Varon said in an email that the group 'regularly communicates with HHS on public health issues, including vaccine policy. While specifics aren't disclosed, it's part of their mission to guide such processes.' Of all the new appointees, Dr. Cody Meissner has the most vaccine expertise. He is a pediatric infectious disease expert at Dartmouth University who also has a long history of government service. He previously served on ACIP from 2008 to 2012 and served on the group of independent experts who advised the FDA on its vaccine decisions during the pandemic. He's also been a member of vaccine advisory boards, including for the American Academy of Pediatrics, and was the chair of the National Vaccine Injury Compensation Program. He has co-authored dozens of studies and position statements on vaccines. During the pandemic, he co-authored an editorial in The Wall Street Journal with Dr. Marty Makary, who is now commissioner of the FDA, arguing against the use of masks for kids. He recently told Reuters that he supports Kennedy's decision not to recommend Covid-19 vaccines for pregnant women and healthy children. In a social media post, infectious disease expert Dr. Michael Mina called Meissner a 'rigorous scientist and has defended vaccines' and a 'terrific choice.' Meissner did not respond to CNN's request for comment for this story. Kennedy's post about Pagano notes that he's a board-certified emergency medicine physician with more than 40 years of experience, including service on hospital committees, and is a strong advocate for evidence-based medicine. He appears to be licensed in both California and Florida. In posts on a blog linked to the X account with his name, Pagano wrote in 2017 that it was a 'disappointment' that Republicans failed to repeal and replace Obamacare, and he advocated for 'transparent, cost-based pricing' in health care. Pebsworth is a registered nurse and has a doctorate in health services organization and policy. She has worked in health care for more than 45 years, according to a brief bio that Kennedy posted to X. She's a regional director for the National Association of Catholic Nurses. She has served as a consumer representative to the FDA's Vaccines and Related Biological Products Advisory Committee, or VRBPAC, and on subcommittees for HHS's National Vaccine Advisory Committee, along with other federal and congressional appointments. She has been a board member of the National Vaccine Information Center, a group that says it 'is dedicated to preventing vaccine injuries and deaths through public education and advocating for informed consent protections in medical policies and public health laws.' Articles and videos on its website say that vaccine injuries are common while the benefits of immunizations are questionable, call for more study of vaccines on the childhood schedule and promote the false idea that vaccines cause autism. As part of that group, Pebsworth made 'Ask Nurse Vicky' videos talking about vaccine injuries and informed consent. In one of the videos, she shared that she believes her son was injured by vaccines he received during a routine doctor's visit when he was 15 months old. In 2009, disgraced British physician Andrew Wakefield introduced Pebsworth's son before he sang and played keyboards at an autism dinner. Wakefield helped cause a worldwide panic in 1998 after he published a study suggesting that vaccines cause autism, but many subsequent studies have disproven the link. He was stripped of his medical license in 2010. Wakefield called Pebsworth 'my great friend.' Pebsworth did not respond to CNN's request for comment. Kennedy listed Dr. Michael Ross as a clinical professor at George Washington University and Virginia Commonwealth University, although Ross is not currently employed at either institution. A VCU spokesperson told CNN that Ross was an affiliate faculty member with the School of Medicine's Inova Campus from 2006 to 2021, when the VCU and Inova partnership ended. A spokesperson for GWU said Ross began working at the university in 1979, but he has not had a faculty appointment there since 2017. His LinkedIn lists his work there ending in May 2025. The Virginia-based obstetrics and gynecology physician announced a month ago that he had joined Manta Pharma, a Maryland biotech firm focused on AI-based delivery of therapies for autoimmune diseases, diabetes, drug addiction and HIV/AIDS. Ross' other current employer, private equity group Havencrest Capital Management, describes him as a 'serial CEO' who has served on the boards of multiple private health care companies. On his LinkedIn page, Ross says that while CEO of a generic pharmaceutical company, he engineered the acquisition of a stem cell company 'and an investment in a vaccine company.' Ross previously served as president of CPL Inc., the North American division of Indian generic drugmaker Cadila Pharmaceutical, and was a board member of the Generic Pharmaceutical Association. Ross did not respond to a request for comment on the vaccine company investment and potential recusals while serving on ACIP. CNN's Andrew Kaczynski and Em Steck contributed to this report.

The Most Consumed Veggie in the U.S. Is Full of Pesticides
You've probably heard of the "Dirty Dozen" list. Each year, the Environmental Working Group (EWG) uses data from the USDA to pinpoint the produce with the most pesticides. Last year, strawberries have took the lead. But in the new Shopper's Guide to Pesticides in Produce, which was released on June 12, strawberries have been knocked out of their number one spot. And there are two newcomers to the list. So what's the "dirtiest" fruit or veggie? In this year's list, spinach swapped places with strawberries for the number one spot. The leafy green was found to have "more pesticide residues by weight than any other type of produce," according to the site. And the samples contained more pesticides by weight than any other produce. 75% of non-organic samples contained permethrin, a neurotoxic insecticide banned in Europe. New to the list are blackberries, which were tested by the USDA for the first time in 2023. And, potatoes, the most-consumed vegetable in the country, also made it to the Dirty Dozen. 90% of potato samples tested positive for chlorpropham, a chemical that prevents sprout growth—and a chemical that's banned in the European Union. "EWG's Shopper's Guide is a tool to inform consumers and help them with their produce shopping choices, with the goal of everyone eating more fruits and vegetables,' says Alexis Temkin, Ph.D., EWG Vice President for Science, in the press release. Other fruits and veggies that made it to the Dirty Dozen include dark leafy greens such as kale, collard greens, and mustard greens; grapes; peaches; cherries; nectarines; pears; and apples. Produce with the lowest amounts of pesticide residue made it to the "Clean Fifteen." The top five include pineapples, sweet corn, avocados, papayas, and onions. To determine the list, the EWG looks at pesticide residue from tests performed by the USDA. These tests included over 53,000 samples of 47 washed fruits and vegetables. This year's list used a new methodology to get a more accurate depiction of just how harmful dirty some fruits and veggies may be. In addition to the amount of pesticides, the study looked at toxicity, meaning how harmful the pesticides could be. 'Our research takes into account the potency of each chemical and can help shoppers reduce their overall pesticide burden," says Dayna de Montagnac, M.P.H., an associate scientist for the EWG.

Foodborne illnesses increase during the summer. A doctor explains how to keep safe
Get inspired by a weekly roundup on living well, made simple. Sign up for CNN's Life, But Better newsletter for information and tools designed to improve your well-being. As a salmonella outbreak linked to eggs has sickened 79 people across seven states as of June 5, a California-based company has recalled 1.7 million dozen eggs because of potential contamination, according to the US Food and Drug Administration. This rash of illnesses follows a separate outbreak of salmonella infections tied to recalled cucumbers and the US Department of Agriculture's Food Safety and Inspection Service issuing a public health alert for raw ground beef products that could be contaminated with E. coli. As summer approaches, I wanted to understand more about these foodborne infections. What are common causes and symptoms? What are possible consequences of salmonella and E. coli infections? Why are foodborne infections more common in the summer, and what are food safety practices that everyone should follow? To help me with these questions, I spoke with CNN wellness expert Dr. Leana Wen. Wen is an emergency physician and adjunct clinical associate professor at George Washington University. She previously served as health commissioner of Baltimore, where her responsibilities included overseeing food safety. CNN: What are the most common causes of foodborne infections? What symptoms do people experience? Dr. Leana Wen: Foodborne infections are caused by pathogens, including viruses, bacteria and parasites. Norovirus is the leading cause of foodborne illness in the United States. The virus is implicated in about half of all food-related illnesses, according to the US Centers for Disease Control and Prevention. The pathogen can spread through contaminated food and drink or from person to person when someone touches objects that have been handled by an infected individual and then touches their mouth, or through sharing cups, bowls and utensils. A number of bacteria can also cause foodborne illness. Infections can occur from eating raw or undercooked food. Other illnesses occur due to bacterial contamination in food. Common bacteria implicated in foodborne illness include campylobacter, listeria, salmonella and E. coli. Symptoms of foodborne infections include nausea, vomiting, diarrhea and abdominal cramping. Depending on the cause and on the health of the individual, other symptoms may develop such as fevers, bloody diarrhea and dehydration that worsens underlying health problems. CNN: What are possible consequences of salmonella and E. coli infections? How are they treated? Wen: Salmonella most often spreads to people through contaminated food. While most people who fall ill recover quickly with no long-term consequences, some can become very ill. In the current outbreak involving the California-based egg distributor, 21 people have been hospitalized out of the 79 people sickened, according to the CDC. The key to treatment is hydration. Individuals with diarrhea should keep up fluid intake to prevent dehydration. Those who are vomiting and unable to keep fluids down may need to take anti-nausea medications. Most people will get better without using antibiotics, but they may be needed for individuals at risk of severe illness. E. coli lives in the intestines of humans and many animals. A specific type of E. coli is known to cause a serious infection. This strain, called O157:H7, produces a toxin that can damage the intestinal wall and lead to bloody diarrhea. This is the strain implicated in the recent ground beef recall. The specific danger of O157:H7 is that some people who fall ill from it could develop a complication called hemolytic uremic syndrome, or HUS. This syndrome can lead to permanent health problems such as kidney failure, and in some cases, it is fatal. Individuals who develop an O157:H7 infection should also drink plenty of fluids to prevent dehydration from diarrhea. Antibiotics are specifically not given for these infections because they may increase the risk of developing HUS. Most foodborne infections can be treated at home. Reasons to contact your doctor include inability to keep down fluids, persistent diarrhea over three days, high fevers and bloody stools. Babies, older people and individuals with chronic medical conditions should have a lower threshold for seeking help. CNN: Why are foodborne infections more common in the summer? Wen: The risk of foodborne illness is higher during summer months because bacteria grow more quickly in warmer weather. In addition, people are more likely to have barbecues and outdoor events that involve food. Inadequate preparation or leaving out food for too long can lead to foodborne illnesses. CNN: What are food safety practices that everyone should follow? Wen: It's important to abide by recall notices. If you have purchased a product that is now recalled, do not consume it. Follow other instructions as directed by health authorities. Keep an eye on not only federal advisories but your local health department, which will inform you of possible foodborne illnesses associated with local stores and restaurants. Follow best practices in food preparation. That includes washing produce such as vegetables and fruits, even if they end up getting peeled. Make sure to cook meat and fish to the recommended temperature. Be aware of what utensils and plates you are using with raw meat and fish, and don't use them for other food items. Remember that bacteria multiply quickly at room temperature. Two hours is the limit for leaving food out before throwing it away or storing it in a refrigerator or freezer. If you are outdoors and the ambient temperature is very warm, reduce the limit to one hour. It's also a good idea to avoid unpasteurized or 'raw' milk and uncooked eggs. Of course, be sure to wash your hands often and well with soap and water. People who have diarrhea, vomiting and stomach cramps should not prepare food. Those most vulnerable to severe illness, including older adults, babies, and those who are pregnant or have serious underlying conditions, should be especially careful of foodborne illness as they are of other infections.
