Healthy or high risk? New analysis warns of pesticide residues on some fruits and veggies

By Carey Gillam

Several types of fruits and vegetables generally considered to be healthy can contain levels of pesticide residues potentially unsafe for consumption, according to an analysis conducted by Consumer Reports (CR) released on Thursday.

The report, which is based on seven years of data gathered by the US Department of Agriculture (USDA) as part of its annual pesticide residue reporting program, concluded that 20% of 59 different fruit and vegetable categories included in the analysis carried residue levels that posed “significant risks” to consumers of those foods.

Those high-risk foods included bell peppers, blueberries, green beans, potatoes and strawberries, according to CR. The group found that some green beans even had residues of an insecticide called acephate, which has been banned for use on green beans by US regulators since 2011. In one sample from 2022, levels of methamidophos (a breakdown product of acephate), were more
than 100 times the level CR scientists consider safe. In another sample, acephate levels were 7 times higher than CR considers safe.

Overall, out of the nearly 30,000 total fruit and vegetable samples for which CR examined data, about 8% percent were deemed to have residues at “high risk or very high risk”. Imported produce was more likely to carry high levels of pesticide residues than domestically supplied foods, the report said, noting that residue levels can vary widely from sample to sample.

The results “raise red flags,” according to CR. The report advises that children and pregnant women should consume less than a serving a day of high-risk fruits and vegetables, and less than half a serving per day of “very high-risk ones.”

“People need to be concerned because we see that the more data we gather on pesticides, the more we realize the levels that we previously thought to be safe turn out not to be,” said Michael Hansen, a senior scientist at CR who was recently appointed to a USDA food safety advisory committee.

The organization said the “good news” is that the data showed residues in most of the foods sampled, including 16 of 25 fruit categories and 21 of 34 vegetable types, presented “little to worry about.” Nearly all organic samples showed no concerning levels of pesticide residues.

The report suggests consumers “try snap peas instead of green beans, cantaloupe in place of watermelon, cabbage or dark green lettuces for kale, and the occasional sweet potato instead of a white one.”

EPA called to address “long-ignored health crisis” in Iowa drinking water

By Carey Gillam

US regulators must take immediate action to address a “long-ignored health crisis” stemming from dangerously contaminated drinking water in Iowa, according to a legal petition filed by environmental and health advocacy groups this week.

The Iowa Environmental Council (IEC) and 12 other organizations are calling for the Environmental Protection Agency (EPA) to take a series of steps to reduce harmful nitrate pollution found in water supplies in Northeast Iowa.

The petition highlights the fact that for many years, nitrate concentrations found in thousands of private wells and some public water sources have exceeded the federal limit of 10 milligrams per liter for drinking water.

State agencies have documented the contamination, but have “failed to do what is needed to correct the pervasive threat to human health,” the petition states.

“For decades, Northeast Iowa residents have been exposed to dangerous levels of nitrate contaminated water,” Food & Water Watch attorney Dani Replogle said in a press release. “As the state reckons with high cancer levels and ongoing pollution regulation rollbacks, federal action is needed to safeguard the right to clean water. EPA must exercise emergency authority to hold polluters accountable and deliver safe drinking water in Iowa.”

Food & Water Watch is among the groups joining IEC in its petition. Others include the Environmental Working Group, the Center for Food Safety, the Environmental Law & Policy Center, and several state organizations.

All signs indicate that “dangerous contamination levels will continue or worsen, absent EPA action,” the petition states.

Farm operations are largely to blame for the contamination, both from the runoff of fertilizer applied to fields of corn and other crops, and the runoff of liquified manure generated by large livestock operations that is also often spread on farm fields. The runoff carries nitrates and phosphorus into surface and groundwaters, and ultimately drinking water.

Iowa is one of the nation’s largest farm states for crops and livestock, and Northeast Iowa is particularly vulnerable to farm pollutants because of its “karst” terrain, which features porous limestone that allows surface pollutants to more quickly move into groundwater. All of the drinking water in the karst region of northeast Iowa depends on groundwater aquifers.

Despite these facts, only a small fraction of private wells are tested regularly for nitrates, which are known to cause health problems at high levels, especially for infants. Cancer is a specific concern with nitrate exposure. Still, more than 1,200 wells in the 12-county karst region tested above the federal threshold for safety from 2016 to 2023, the petition states.

Dire threats seen for America’s ‘most endangered’ rivers

By Johnathan Hettinger

Rivers from Arizona to Alaska, Mississippi to Connecticut, and California to the Carolinas face dire threats from climate change, overdevelopment, pollution and water scarcity, according to a new report released by American Rivers this week.

But this year, the most endangered river isn’t a single one — it’s all of the streams in the entire state of New Mexico, according to the report.

The environmental nonprofit, which focuses on river health and publishes an annual list of most endangered waterways in the US, found that New Mexico is the state most likely to be impacted by a US Supreme Court ruling issued last year in the case of Sackett v. EPA, which stripped federal clean water protections for small streams and wetlands across the country.

The Sackett ruling found that the Clean Water Act only applies to continuous and permanent surface waters, meaning that seasonal rivers and wetlands that aren’t directly connected to rivers aren’t covered by the federal law. Instead, it’s up to states to regulate these bodies of water, which account for more than half of all wetlands and streams in the US.

“These streams and wetlands are the beginning of all of our rivers. And all of that water is connected, so when we lose the protections in our headwaters, those wetlands and streams, our rivers are threatened and the long-term quality of your drinking water will likely be harmed,” Tom Kiernan, president and CEO of American Rivers, said in a video released about the list.

In New Mexico, that means the majority of streams are left unprotected because the state does not have a permitting process in place. That could mean dire downstream consequences for rivers, including the Gila, San Juan, Pecos and Upper Rio Grande.

“People depend on this water. We have depended on this water for hundreds of years. This is our tradition, this is our culture. We don’t want to be a people that loses its traditions because we haven’t taken the right steps to protect our rivers,” Vicente Fernandez, acequia mayordomo and community leader, said in a press release.

“It’s getting worse” – US failing to stem tide of harmful farm pollutants

By Keith Schneider

VENICE, LA. Kindra Arnesen is a 46-year-old commercial fishing boat operator who has spent most of her life among the pelicans and bayous of southern Louisiana, near the juncture where the 2,350-mile-long Mississippi River ends at the Gulf of Mexico.

Clark Porter is a 62-year-old farmer who lives in north-central Iowa where he spends part of his day working as an environmental specialist for the state and the other part raising corn and soybeans on hundreds of acres that his family has owned for over a century.

Though they’ve never met, and live 1,100 miles apart, Arnesen and Porter share a troubling kinship – both of their communities are tied to a deepening water pollution crisis that is fouling the environment and putting public health in peril across multiple US states.

Arnesen’s home lies near an oxygen-depleted expanse of the northern Gulf known as the “dead zone,” where dying algae blooms triggered by contaminants flowing out of the Mississippi River choke off oxygen, suffocating shrimp and other marine life.

Porter’s farm is positioned at the center of the Upper Mississippi River Basin where streams and other surface waters saturated with farm wastes flood into the big river, and contaminated groundwater permeates drinking water wells. Cancer incidence in Iowa is among the nation’s highest, and is rising.

The culprit at the center of it all is a colossal tide of fertilizer and animal manure that runs off fields in Iowa and other farm states to find its way into the Mississippi River. The same agricultural pollution problems are plaguing other iconic US waterways, including Chesapeake Bay and Lake Erie.

US farmers use more fertilizer and spread more manure than in most other countries, accounting for roughly 10% of global fertilizer use, behind China and India. But while the nutrients contained in animal manure and fertilizer are known to nourish crop growth, the resulting nitrogen and phosphorous that end up in waterways are known to create severe health problems for people.

A grand government plan to address the problem has cost taxpayers billions of dollars with minimal results so far, and nowhere is the problem more pronounced than in the Mississippi River Basin.

The reasons for the persistent pollution problem are multi-fold, including strong industry opposition to regulations to control the farm contaminants, and a perverse system in which some government programs incentivize farming practices that add to the pollution even as other government programs try to induce farmers to reduce the pollution.

“You’re talking about systemic dysfunction,” said Matt Liebman, professor emeritus of agronomy and sustainable agriculture at Iowa State University.

“A huge victory for public health”: EPA set limits on PFAS toxins in drinking water

By Shannon Kelleher

US regulators on Wednesday put in place the nation’s first legally enforceable limits for levels of six toxic PFAS chemicals in drinking water, saying the moves should prevent thousands of deaths and reduce serious illnesses in people across the country.

The rule is designed to reduce exposure to these per-and polyfluoroalkyl substances (PFAS) – also called “forever chemicals” – for about 100 million people nationwide, according to the US Environmental Protection Agency (EPA). Exposure to PFAS has been linked to “deadly cancers, impacts to the liver and heart, and immune and developmental damage to infants and children, the EPA said.

“Today we can celebrate a huge victory for public health in this country,” Rob Bilott, a lawyer who has become famous for his work against PFAS, said in a statement. Bilott has spent decades pushing for PFAS regulations and to hold PFAS manufacturers accountable for releasing the dangerous chemicals into the marketplace.

“It should never have taken this long to address such serious threats to public health and our environment,” Bilott said, noting that he first alerted the EPA to the presence of PFAS in US drinking water more than twenty-three years ago.

The new rule sets a limit of four parts per trillion (ppt) for two types of PFAS – perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), which are both known to be particularly hazardous.

The EPA acknowledged that there is “no level of exposure to these contaminants without risk of health impacts, including certain cancers,” and said it was setting a “non-enforceable health-based goal,” at zero for PFOA and PFOS.

In “crucial step”, EPA finalizes rule to reduce cancerous chemical plant emissions

By Carey Gillam

More than 200 US chemical plants face new requirements that should slash toxic air pollution and reduce cancer risks for hundreds of thousands of people living near the facilities, officials said on Tuesday.

The action formalizes a hotly debated proposal by the Environmental Protection Agency (EPA) to cut out over 6,000 tons of toxic air pollution annually. The agency is taking specific aim at emissions of ethylene oxide (EtO), which is used in the production of many products and for sterilization of medical equipment, and chloroprene, used to make synthetic rubber.

Most of the impact would be seen in plants in Texas and Louisiana, as well as in the Ohio River Valley, in communities that have become notorious for high rates of cancer. People living near a chloroprene plant in St. John the Baptist Parish, Louisiana, face a cancer risk 50 times higher than the national average, for instance. The community has been dubbed “Cancer Alley.”

“This final rule delivers on EPA’s commitment to protecting public health for all, especially communities historically overburdened by pollution,” EPA Administrator Michael Regan said in a press conference.

An EPA analysis shows that once the final rule is implemented, “no one will again face elevated cancer risks from EtO or chloroprene emissions from the equipment and processes covered by this rule,” Regan said. He said agency actions would cut the cancer risk for people living near the plants by 96%.

The move is part of a “government-wide commitment to ending cancer as we know it,” he said.

Concerned about developing babies, EPA warns about danger of weed killer used on farms, golf courses

By Johnathan Hettinger

The US Environmental Protection Agency (EPA) on Monday took the rare step of issuing a warning about “serious, permanent, and irreversible health risks” associated with a chemical used to kill weeds on farms and golf courses and athletic fields.

Citing “significant health risks to pregnant individuals and their developing babies,” the agency said farmworkers and others handling dimethyl tetrachloroterephthalate, more commonly known as DCPA, were at risk, as are people who might play on courses or fields recently sprayed with the pesticide.

The most serious risks extend to the developing babies of pregnant women, especially those handling DCPA products. The agency said pregnant women exposed to DCPA could experience changes to fetal thyroid hormone levels, which are linked to low birth weight, impaired brain development, decreased IQ, and impaired motor skills later in life. Though product labels say people should stay out of fields for 12 hours after they are sprayed with DCPA, the EPA said evidence indicates that in many cases, sprayed fields would be unsafe for 25 days or more. The agency additionally said that mothers and their developing babies could be at risk if they live near areas where DCPA is used because the pesticide can drift.

“EPA has determined that currently registered products containing the herbicide DCPA likely cannot be used under current label directions without posing serious risks of concern in humans,” Ed Messina, director of the Office of Pesticide Programs, stated in a letter to AMVAC, a California-based company that is the sole manufacturer of the pesticide.

The product is primarily used to control weeds on crops such as broccoli, Brussels sprouts, cabbage and onions, though it is also used in some non-agricultural settings. Last year, AMVAC agreed to end its use on turf, citing health concerns.

The EPA is currently reviewing whether to reapprove DCPA. Though the agency rarely takes the step of canceling a pesticide, it is considering that route, including suspending DCPA during review process, the agency said.

“Due to the serious potential risks posed by DCPA use, EPA will be pursuing these regulatory options as soon as practicable,” Messina wrote in the communication to AMVAC.

Mexico delays planned April 1 glyphosate ban

By Carey Gillam and Johnathan Hettinger

After standing firm for more than three years on plans to enact a ban on the weed killer glyphosate starting today, Mexican officials said they were delaying the ban.

Mexico is currently embroiled in a trade dispute with the United States over its unwillingness to accept genetically modified (GM) corn, typically altered to tolerate being sprayed with glyphosate and to manufacture toxins that repel pests, and Mexican officials have repeatedly stated that they consider both GM corn and glyphosate as threats to the health of the Mexican population as well as to the health of the environment.

But in a surprising reversal, less than a week before the ban was to kick in on April 1, government officials announced that glyphosate use could continue until other options for weed control are found. The move came amid reported heavy lobbying from powerful global agrochemical companies and pressure from US trade officials. Similarly, in 2019, Thailand backed down from a planned glyphosate ban after pressure from US officials and industry actors.

Fernando Bejarano, of the Pesticide Action Network in Mexico, said that the move comes after pressure from industry and US officials.

Postcard from California: The global plastics crisis is a threat to human health

By Bill Walker

Last April, an annual assessment of the clarity of Lake Tahoe found it was the clearest it had been since the 1980s. But just months later, scientists reported that the iconic alpine lake straddling the California-Nevada border had alarming levels of a nearly invisible form of pollution: microplastics.

Microplastics are particles of plastic measuring less than 5 millimeters – roughly the size of a pencil eraser – generated largely from the breakdown of discarded plastic bottles and other plastic items. The US is the world’s largest generator of plastic waste, as people throw away more than 27 million tons of plastic annually.

In a study released last July, an international team of researchers found that Lake Tahoe had the third-highest concentration of microplastics out of 38 large lakes in 23 countries. Tahoe’s crystal blue waters held higher concentrations of microplastics than the floating garbage patches littering the world’s oceans, the study determined.

The researchers measured only relatively large microplastics – the width of a few human hairs or larger – not the “nanoplastics” that can be hundreds of times smaller. The Tahoe Basin has some of the most stringent environmental regulations in the US, suggesting that the probable source is airborne plastic particles from afar contaminating the snow that melts into the lake.

Microplastics’ threat to fish, marine mammals and other wildlife is well documented. Now there’s growing evidence that they’re also hazardous to people.

Last year, a report from the California State Policy Evidence Consortium, commissioned by state legislators, raised concerns about microplastics’ suspected human health effects, including reproductive harm, respiratory problems and biological changes that could lead to intestinal cancer.

‘We are defending your products:’ Emails reveal coordination between US government, industry in foreign trade disputes

By Johnathan Hettinger and Carey Gillam

Against the backdrop of a fierce battle between the United States and Mexico over the safety of certain farming products, newly obtained government communications provide fresh evidence of how powerful corporate interests often drive US officials to meddle in foreign affairs.

The records are the latest to emerge that show how tightly the US government works with global crop and chemical companies to try to block other governments around the world from placing restrictions on pesticides and, as in the case of Mexico, on certain genetically modified crops.

The US is currently embroiled in a bitter trade battle with Mexico, but also has waged war against Thailand and the European Union over efforts to ban pesticides that are key to the corporate profits of companies such as Bayer and Syngenta.

The newly obtained emails add to earlier revelations, also found in government records, by providing greater detail about how the Office of the US Trade Representative (USTR), the federal agency responsible for American trade policy, works to benefit agrochemical companies while shrugging off evidence presented by foreign governments that pesticides are posing dire risks to the safety of their environment and their citizens.

Similarly, the US Department of Agriculture (USDA) and the US Environmental Protection Agency (EPA) are shown in the emails helping push back against countries that try to ban pesticides linked to human health issues and the demise of crucial species.

The latest batch documents were obtained through Freedom of Information Act requests by the nonprofit Center for Biological Diversity and provided to The New Lede (TNL).

“Trade now poses one of the biggest barriers to keeping pesticides in wide use in the US, and pesticide companies are taking notice,” said Nathan Donley, a senior scientist at the Center for Biological Diversity. “The US can’t keep using pesticides at this rate if other countries won’t buy our contaminated food, so the focus has now turned to quashing any attempt by smaller countries to protect their citizens and their food supply.”

“The push is coming from the US government but it’s at the behest of pesticide companies,” he said. “It’s basically soft imperialism with our government as the puppet and large corporations pulling the strings.”
