EPA action on nerve agent used in food applauded, but concerns persist
By Carey Gillam
A proposal by US regulators to issue a ban on most uses of a pesticide that acts as a nerve agent was applauded by health advocates this week, though some warned the proposal doesn’t go far enough.
The Environmental Protection Agency (EPA) proposal targets acephate, a widely used bug-killing chemical whose residues have been found in foods generally considered healthy, such as celery, green beans and tomatoes. The chemical is also found in drinking water.
The agency said it plans to end all uses of acephate on food because it had determined – after more than 50 years of use – that it cannot be certain that “no harm would result” from acephate exposure, particularly from acephate levels in drinking water.
Acephate is part of a class of nerve agent chemicals known as organophosphates that are popular with US farmers who use them to fight pests in their fields. But the chemicals have been linked to a range of adverse health effects, particularly in children, such as reduced IQ, attention deficit disorders, and autism spectrum disorders. Acephate, long banned in the European Union, has also been linked to cancer among other health problems.
“We are applauding this. It is long overdue,” said Patti Goldman, a lawyer with Earthjustice, one of several health and environmental advocacy organizations that have pushed the EPA for year to take action on acephate and other organophosphates. “We are really pleased that EPA is proposing to ban all food uses.”
Earthjustice, along with several other health, civil rights, farmworker, and learning disability groups, filed a petition in 2011 calling on the EPA to prohibit all organophosphates.
The EPA action came late last month, coinciding with a report by ProPublica, which revealed how the agency had in the past justified increasing the amount of acephate allowed on food by removing safety margins that are called for in federal law to protect children from pesticide residues in their diets.
The new EPA proposal reiterates that stance, saying that when using “new approach methods” for developmental neurodevelopmental toxicity (DNT NAMs), there was little scientific support for adding those protections for children.
Nonetheless, the EPA said its assessments show current uses of acephate pose both dietary and aggregate risks that are “inconsistent” with safety standards.

Despite ban, EPA grants ’emergency’ approval for bee-killing insecticide for 10th straight year
By Johnathan Hettinger
US regulators have approved the emergency use of clothianidin on Florida citrus trees for the tenth straight year, once again allowing farmers to use the insecticide despite its known risk to endangered species and pollinators critical to the health of the food supply.
Since 2015, the Environmental Protection Agency (EPA) has had a moratorium on new uses of neonicotinoid insecticides, including clothianidin, because of evidence that the class of pesticides is linked to pollinator decline. Neonics have been shown to be particularly harmful to bees, which help pollinate important crops, such as vegetables, nuts, cotton and more.
In a 2023 analysis, the EPA found that clothianidin and other neonics are driving hundreds of species protected under the Endangered Species Act toward extinction. Neonics are banned in Europe, and the EU has proposed essentially banning clothianidin on crops imported into the EU.
Despite the concerns, the EPA has continually allowed farmers in Florida to drench the soil surrounding citrus trees with clothianidin to help fight an insect called Asian citrus psyllid, which spreads a disease the industry calls “citrus greening.” The EPA renewed that exemption last week. Florida’s citrus production has seen a steep decline over the last 20 years due largely to the dreaded disease.
“It is the no. 1 issue in citrus, probably in the world,” said Lauren Diepenbrock, an assistant professor & citrus entomology extension specialist at the University of Florida. In the past 20 years, Florida citrus production declined from 300 million boxes in 2003-04 to under 20 million boxes in 2022-23.

Controversial California power plant set to stay online after court decision
By Shannon Kelleher
A federal court on Monday cleared the way for California’s last nuclear power plant to keep operating for five years after its licenses expire, rejecting arguments from environmental advocates that the facility poses ongoing risks that could prove catastrophic, including the potential for a “nuclear meltdown”.
The move by the 9th US Circuit Court of Appeals upholds a Nuclear Regulatory Commission (NRC) decision to exempt Pacific Gas & Electric (PG&E)’s Diablo Canyon Power Plant from a rule that would require its two reactors to shut down in 2024 and 2025. The court rejected the environmental groups’ claims that the NRC did not properly account for safety and environmental concerns.
“We filed our lawsuit because NRC was playing fast and loose with decisions that could quite literally lead to a nuclear meltdown,” Hallie Templeton, legal director for the nonprofit Friends of the Earth, said in a statement. “We will keep fighting to ensure that all involved officials properly and thoroughly apply pertinent laws to Diablo’s attempted extension.”
The NRC’s decision to grant an exemption for Diablo Canyon, which has been operational since 1985, was not “arbitrary, capricious, or contrary to law,” US Circuit Judge Consuelo Callahan wrote in his opinion. “NRC adequately explained why California’s changing energy needs constituted a special circumstance, and why the record supported its findings of no undue risk to the public health and safety.”
The court decision comes on the heels of a lawsuit Friends of the Earth filed earlier this month against the US Department of Energy (DOE) over a more than $1 billion award the agency is granting PG&E to help keep Diablo Canyon up and running. The group alleges that the DOE’s assessment of Diablo Canyon’s environmental impact relies on an outdated analysis that fails to incorporate a range of safety risks posed by the plant, including an outdated cooling mechanism, dangerous wear and tear, potentially catastrophic risks from earthquakes, and increased flooding risks due to climate change.
Critics of the plant also say it will be costly for Californians. A 2023 analysis by the Environmental Working Group suggested Diablo Canyon could cost the public nearly $45 billion if it stays open through 2045.

Postcard from California: State emits more of an obscure climate-heating gas than the entire rest of the US
By Bill Walker
Among US states, California is a leader in efforts to cut emissions of the greenhouse gases that fuel the climate crisis. But just three counties in Southern California emit far more of one little-known greenhouse gas than all other US states combined.
Blame termites – and the tragic, too-frequent mistake of replacing one environmentally harmful chemical with another that turns out to be just as bad.
Sulfuryl fluoride is a fumigant pesticide first made by Dow Chemical Co., marketed since 1959 as Vikane. To kill western drywood termites, pest control companies cover infested houses with tents and then pump in Vikane. Houses tented for fumigation are a common sight in Southern California, where warm, dry weather leaves wooden buildings highly susceptible to infestations of the hard-to-exterminate species.
The colorless, odorless, highly neurotoxic gas that kills termites is also a danger to humans. That’s why Vikane must be spiked with another toxic pesticide gas called chloropicrin, which has an intensely irritating smell that is meant to warn people against entering a house until the fumigant has dispersed in 24 to 72 hours.
California Department of Pesticide Regulation (DPR) records show that between 1992 and 2017, at least 16 Californians died from sulfuryl fluoride poisoning after going inside fumigated houses too soon. In the same period DPR recorded more than 200 cases of human exposure that caused breathing problems, dizziness, nausea, and other symptoms.
But the biggest problem with Vikane is that, when fumigation tents are removed and sulfuryl fluoride disperses into the atmosphere, it is a greenhouse gas much more powerful than carbon dioxide (CO2).

US health advocacy groups support Mexico in GMO trade dispute
By Johnathan Hettinger
More than a dozen North American organizations have weighed in to support Mexico in its trade dispute with the United States over Mexico’s ban of genetically modified (GM) corn, agreeing that the nation has the right to protect human health from food ingredients it considers hazardous.
“The burden of proof, so far generated for Mexico, [should] be reversed. It should be the United States that proves that there is no long-term risk to human health from the direct consumption of [genetically modified corn], in the particular case of the Mexican consumption pattern,” Mexico-based El Poder del Consumidor, a consumer rights association, wrote in comments filed earlier this month.
In the series of recent filings submitted to the United States-Mexico-Canada Agreement secretariat, only one group, the US-based Biotechnology Innovation Organization (BIO) defended the United States’ position that Mexico is violating trade agreements by banning the corn for foods for human consumption. Bayer AG, which bought GMO crop developer Monsanto in 2018, is a BIO member as are other companies that make and sell GMO seeds and agrochemicals.
The Canadian government also defended the US position. Both Canada and the US accuse Mexico of failing to base its decision on GMO corn on valid scientific research. The governments say science shows GMO corn is not a threat to human health. Mexico disagrees, and says that solid research does show risks to humans from foods made with genetically altered corn. Mexico also objects to GMO corn for environmental and cultural reasons.
“There is a basis in the Mexican legal framework that makes it necessary for the Mexican government to transition away from GM corn to protect its people,” Javier Zuñiga, an attorney with Mexico-based El Poder del Consumidor, said in a webinar held on Tuesday. “It guarantees the right to live in a healthy way.”
Mexico is also working to ban glyphosate, the active ingredient in Bayer’s Roundup weedkiller and other herbicides. Glyphosate is commonly used on genetically modified crops, including corn. The ban on glyphosate in Mexico was set to go into effect April 1, but was delayed indefinitely last month.

Not just Mexico – US worries over barriers to agricultural trade across the world
By Johnathan Hettinger
From Algeria to Vietnam, Norway to Nigeria, and the European Union to China, regulation of agriculture biotechnology by countries around the world is creating increasingly concerning barriers to US agriculture and technology trade, according to a recent report from the Office of the US Trade Representative (USTR).
The report shows the US government is highly concerned about what it sees as inconsistent and unscientific regulation of farm chemicals and genetically modified crops that are widely used in the United States but are subjects of concern abroad. Farmers in the United States annually spray millions of pounds of pesticides that are banned in other countries, including the EU, China and Brazil.
Among other concerns, the US cites “excessive” requests for data on certain products and expresses frustration that the EU seeks to ban pesticides until they are proven safe, instead of approving pesticides until they are proven unsafe.
In a 394-page report, the USTR detailed a range of concerns with specific countries, including those related to its ongoing bitter battle with Mexico over genetically modified crops (GMOs).
Mexico has not approved a new genetically modified cotton variety since at least 2018, the report notes, despite the cultivation of GMO cotton in Mexico for more than 25 years “with no evidence of adverse impact on the environment, biodiversity, or animal or plant health.” US officials are continuing to press the country on the issue, just as they are on Mexico’s restrictions on GMO corn. The US has also battled with Mexico over its efforts to ban glyphosate weed killer, developed by Monsanto.
In another example cited in the report, the US government complains that Taiwan’s decision to ban genetically modified food in school meal programs is not based on science.
Yet, the document makes it clear that the question of science is also a concern in the countries at odds with the US. Many other countries have expressed concern with what they see as the United States’ lax pesticide laws, driven not by science but by corporate influence.

EPA announces $7 billion to make solar more accessible
By Shannon Kelleher
The US Environmental Protection Agency (EPA) said on Monday that it will provide $7 billion to create or expand low-income residential solar programs across the country, a move the agency said will lower energy costs for roughly 900,000 households in communities that might otherwise struggle to access the alternative energy source.
The grants will be awarded to 60 recipients made up of the state agencies, Tribes and nonprofits selected through a grant competition funded by the Inflation Reduction Act. The program includes services to help communities overcome barriers to switching to solar, including assistance with siting and permitting solar projects and connecting to the grid. according to an EPA press release.
In at least 25 states and territories, the agency says the grants will launch new programs “where there has never been a substantial low-income solar program before.”
“The United States can and must lead the world in transforming our energy systems away from fossil fuels,” said US Sen. Bernie Sanders (D-VT) said in a statement.
The “Solar for All”, which Sanders introduced, “will not only combat the existential threat of climate change by making solar energy available to working class families, it will also substantially lower the electric bills of Americans and create thousands of good-paying jobs,” Sanders said.

EPA moves to make polluters foot the bill for PFAS cleanup
By Shannon Kelleher
US regulators on Friday finalized a rule designating two widespread PFAS chemicals as hazardous substances, a step they say will ensure polluters pay to clean up contamination and reduce Americans’ exposure to the toxic chemicals.
Under the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), or Superfund law, the rule will require leaks and spills of these per- and polyfluoroalkyl substances (PFAS) to be immediately reported and will enable investigation and cleanup of the chemicals.
The finalized rule “enables the agency to use one of its strongest enforcement tools to compel polluters to pay for or conduct investigations and cleanup, rather than taxpayers,” said the US Environmental Protection Agency (EPA) in a press release. “Designation is especially important as delay in addressing contamination allows PFOA and PFOS more time to migrate in water and soil, worsening existing contamination.”
“This is great news for the many communities grappling with PFAS contamination – many of which are also low income and communities of color,” said Tracey Woodruff, an environmental health researcher at the University of California, San Francisco and a former EPA senior scientist.
The move comes days after the EPA announced the nation’s first legally enforceable drinking water limits for the same chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), along with four other PFAS.
So-called “forever chemicals,” which do not break down naturally, have been used for decades in consumer products ranging from nonstick pans to waterproof clothes and stain resistant carpet. Exposure to PFAS has been linked to cancers, liver and heart problems, and immune and developmental damage in children, according to the EPA. The chemicals are found in the blood of almost all Americans.
“Sustainable” company behind POM juice among California’s top paraquat sprayers
By Shannon Kelleher
The Wonderful Company, which has been recognized for its sustainability initiatives and owns POM pomegranate juice, Fiji Water, and other popular brands, was among California’s top sprayers of the toxic weedkiller paraquat in 2021, according to a new analysis.
The major agricultural company, which grows pistachios, almonds, and pomegranates, was California’s second largest sprayer of paraquat, which has been linked to Parkinson’s disease. Wonderful accounted for over 13% of the state’s paraquat use, applying almost 57,000 lbs to its fields, according to the analysis published Thursday by the Environmental Working Group (EWG), which drew from data obtained from the California Department of Pesticide Regulation and county agriculture commissioners.
The company’s website states that “environmental sustainability is at the center of our work” and that the company, “in all its operations, must be a deeply responsible steward of the environment, and lead by example to create a sustainable future.” Wonderful has invested $400 million in sustainable agriculture, according to its website.
The Wonderful Company did not immediately respond to request for comment.
Just ten farms and companies in the top agricultural state sprayed 40% of all paraquat used in California in 2021, the analysis found. The biggest paraquat user in the state was the J.G. Boswell Company, a major producer of cotton, tomatoes for paste, and seed crops, which also accounted for over 13% of California’s paraquat use that year.
“Folks have known about paraquat for a while…but I think it’s clear the public doesn’t fully appreciate where these pesticides are being applied and how close it is to their communities,” said Geoff Horsfield, a policy director at the Environmental Working Group who works on pesticides and other agricultural issues.
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.”
