What Produce Should You Be Buying Organic?

Food

All adults and children should eat more fruits and vegetables, whether they are organic or conventionally grown. With EWG's 2018 Shopper's Guide to Pesticides in Produce™, you can choose healthy produce while minimizing unwanted doses of multiple toxic pesticides.


Many shoppers don't realize that pesticide residues are common on conventionally grown produce, even after it is carefully washed or peeled. EWG's analysis of the most recent tests by the Department of Agriculture found that nearly 70 percent of samples of conventionally grown produce were contaminated with pesticide residues.

The USDA tests found a total of 230 different pesticides and pesticide breakdown products on the thousands of produce samples analyzed. EWG's analysis of the tests shows that there are stark differences among various types of produce. The Shopper's Guide lists the Dirty Dozen™ fruits and vegetables with the most pesticide residues, and the Clean Fifteen™, for which few, if any, residues were detected.

Key findings from this year's guide:

  • More than one-third of strawberry samples analyzed in 2016 contained 10 or more pesticide residues and breakdown products.
  • More than 98 percent of samples of strawberries, peaches, potatoes, nectarines, cherries and apples tested positive for residue of at least one pesticide.
  • Spinach samples had, on average, almost twice as much pesticide residue by weight compared to any other crop.
  • Avocados and sweet corn were the cleanest. Less than 1 percent of samples showed any detectable pesticides.
  • More than 80 percent of pineapples, papayas, asparagus, onions and cabbages had no pesticide residues.
  • No single fruit sample from the Clean Fifteen tested positive for more than four pesticides.

"It is vitally important that everyone eats plenty of produce, but it is also wise to avoid dietary exposure to toxic pesticides, from conception through childhood," said Sonya Lunder, senior analyst with EWG. "With EWG's guide, consumers can fill their fridges and fruit bowls with plenty of healthy conventional and organic produce that isn't contaminated with multiple pesticide residues."

Twenty-five years after the National Academy of Sciences issued a landmark report raising concerns about children's exposure to toxic pesticides through their diets, Americans still consume a mixture of pesticides every day. While vegetables and fruits are essential components of a healthy diet, research suggests that pesticides in produce may pose subtle health risks.

New Science Links High-Pesticide Produce to Poorer Fertility

Two recent studies from the Harvard T.H. Chan School of Public Health found a surprising association between consuming high-pesticide-residue produce and fertility problems among study participants.

Women who reported eating two or more servings per day of produce with higher pesticide residues were 26 percent less likely to have a successful pregnancy during the study than participants who ate fewer servings of these foods. Male participants who ate high-residue produce had poorer sperm quality. Both studies enrolled couples seeking treatment at a fertility clinic, and found that the frequency of eating low-residue fruits and vegetables was not associated with fertility problems.

The findings from the studies raise important questions about the safety of pesticide mixtures found on produce, and suggest that people should focus on eating the fruits and vegetables with the fewest pesticide residues. Importantly, the studies' definitions of higher- and lower-pesticide foods mirror those used for EWG's Dirty Dozen and Clean Fifteen lists.

Pesticide That Causes Brain Damage in Kids Detected on Some Produce

The neurotoxic insecticide chlorpyrifos, which can harm children's brains and nervous systems, is applied to apples, bell peppers, peaches, nectarines and other produce.

The U.S. Environmental Protection Agency was slated to ban all uses of chlorpyrifos on foods in early 2017. But EPA Administrator Scott Pruitt reversed course after Dow Chemical, which manufactures the chemical, complained. The American Academy of Pediatrics and EWG urged Pruitt to reconsider his decision, to no avail.

The Academy, which represents 66,000 of the nation's pediatricians, recommends that parents consult EWG's Shopper's Guide to help reduce their children's ingestion of pesticides.

"There is a reason pediatricians encourage parents to consult EWG's guide and take other steps to reduce their child's exposure pesticides," said Dr. Philip Landrigan of the Icahn School of Medicine at Mount Sinai in New York. "Pesticides can cause harm to infants, babies and young children at even low levels like those found on some foods."

Landrigan, dean of global health and director of the Children's Environmental Health Center at Mt. Sinai, was the principal author of the National Academy of Sciences study, Pesticides in the Diets of Infants and Children. The study led to enactment of the 1996 Food Quality Protection Act, which set safety standards for pesticides on foods.

The rallying cry to build it again and to build it better than before is inspiring after a natural disaster, but it may not be the best course of action, according to new research published in the journal Science.

"Faced with global warming, rising sea levels, and the climate-related extremes they intensify, the question is no longer whether some communities will retreat—moving people and assets out of harm's way—but why, where, when, and how they will retreat," the study begins.

The researchers suggest that it is time to rethink retreat, which is often seen as a last resort and a sign of weakness. Instead, it should be seen as the smart option and an opportunity to build new communities.

"We propose a reconceptualization of retreat as a suite of adaptation options that are both strategic and managed," the paper states. "Strategy integrates retreat into long-term development goals and identifies why retreat should occur and, in doing so, influences where and when."

The billions of dollars spent to rebuild the Jersey Shore and to create dunes to protect from future storms after Superstorm Sandy in 2012 may be a waste if sea level rise inundates the entire coastline.

"There's a definite rhetoric of, 'We're going to build it back better. We're going to win. We're going to beat this. Something technological is going to come and it's going to save us,'" said A.R. Siders, an assistant professor with the disaster research center at the University of Delaware and lead author of the paper, to the New York Times. "It's like, let's step back and think for a minute. You're in a fight with the ocean. You're fighting to hold the ocean in place. Maybe that's not the battle we want to pick."

Rethinking retreat could make it a strategic, efficient, and equitable way to adapt to the climate crisis, the study says.

Dr. Siders pointed out that it has happened before. She noted that in the 1970s, the small town of Soldiers Grove, Wisconsin moved itself out of the flood plain after one too many floods. The community found and reoriented the business district to take advantage of highway traffic and powered it entirely with solar energy, as the New York Times reported.

That's an important lesson now that rising sea levels pose a catastrophic risk around the world. Nearly 75 percent of the world's cities are along shorelines. In the U.S. alone coastline communities make up nearly 40 percent of the population— more than 123 million people, which is why Siders and her research team are so forthright about the urgency and the complexities of their findings, according to Harvard Magazine.

Some of those complexities include, coordinating moves across city, state or even international lines; cultural and social considerations like the importance of burial grounds or ancestral lands; reparations for losses or damage to historic practices; long-term social and psychological consequences; financial incentives that often contradict environmental imperatives; and the critical importance of managing retreat in a way that protects vulnerable and poor populations and that doesn't exacerbate past injustices, as Harvard Magazine reported.

If communities could practice strategic retreats, the study says, doing so would not only reduce the need for people to choose among bad options, but also improve their circumstances.

"It's a lot to think about," said Siders to Harvard Magazine. "And there are going to be hard choices. It will hurt—I mean, we have to get from here to some new future state, and that transition is going to be hard.…But the longer we put off making these decisions, the worse it will get, and the harder the decisions will become."

To help the transition, the paper recommends improved access to climate-hazard maps so communities can make informed choices about risk. And, the maps need to be improved and updated regularly, the paper said as the New York Times reported.


"It's not that everywhere should retreat," said Dr. Siders to the New York Times. "It's that retreat should be an option. It should be a real viable option on the table that some places will need to use."
