Pesticide industry ‘immunity shield’ stripped from US appropriations bill

Democrats and the Make America Healthy Again movement pushed back on the rider in a funding bill led by BayerIn a setback for the pesticide industry, Democrats have succeeded in removing a rider from a congressional appropriations bill that would have helped protect pesticide makers from being sued and could have hindered state efforts to warn about pesticide risks.Chellie Pingree, a Democratic representative from Maine and ranking member of the House appropriations interior, environment, and related agencies subcommittee, said Monday that the controversial measure pushed by the agrochemical giant Bayer and industry allies has been stripped from the 2026 funding bill.

In a setback for the pesticide industry, Democrats have succeeded in removing a rider from a congressional appropriations bill that would have helped protect pesticide makers from being sued and could have hindered state efforts to warn about pesticide risks.Chellie Pingree, a Democratic representative from Maine and ranking member of the House appropriations interior, environment, and related agencies subcommittee, said Monday that the controversial measure pushed by the agrochemical giant Bayer and industry allies has been stripped from the 2026 funding bill.The move is final, as Senate Republican leaders have agreed not to revisit the issue, Pingree said.“I just drew a line in the sand and said this cannot stay in the bill,” Pingree told the Guardian. “There has been intensive lobbying by Bayer. This has been quite a hard fight.”The now-deleted language was part of a larger legislative effort that critics say is aimed at limiting litigation against pesticide industry leader Bayer, which sells the widely used Roundup herbicides.An industry alliance set up by Bayer has been pushing for both state and federal laws that would make it harder for consumers to sue over pesticide risks to human health and has successfully lobbied for the passing of such laws in Georgia and North Dakota so far.The specific proposed language added to the appropriations bill blocked federal funds from being used to “issue or adopt any guidance or any policy, take any regulatory action, or approve any labeling or change to such labeling” inconsistent with the conclusion of an Environmental Protection Agency (EPA) human health assessment.Critics said the language would have impeded states and local governments from warning about risks of pesticides even in the face of new scientific findings about health harms if such warnings were not consistent with outdated EPA assessments. The EPA itself would not be able to update warnings without finalizing a new assessment, the critics said.And because of the limits on warnings, critics of the rider said, consumers would have found it difficult, if not impossible, to sue pesticide makers for failing to warn them of health risks if the EPA assessments do not support such warnings.“This provision would have handed pesticide manufacturers exactly what they’ve been lobbying for: federal preemption that stops state and local governments from restricting the use of harmful, cancer-causing chemicals, adding health warnings, or holding companies accountable in court when people are harmed,” Pingree said in a statement. “It would have meant that only the federal government gets a say – even though we know federal reviews can take years, and are often subject to intense industry pressure.”Pingree tried but failed to overturn the language in a July appropriations committee hearing.Bayer, the key backer of the legislative efforts, has been struggling for years to put an end to thousands of lawsuits filed by people who allege they developed cancer from their use of Roundup and other glyphosate-based weed killers sold by Bayer. The company inherited the litigation when it bought Monsanto in 2018 and has paid out billions of dollars in settlements and jury verdicts but still faces several thousand ongoing lawsuits. Bayer maintains its glyphosate-based herbicides do not cause cancer and are safe when used as directed.When asked for comment on Monday, Bayer said that no company should have “blanket immunity” and it disputed that the appropriations bill language would have prevented anyone from suing pesticide manufacturers. The company said it supports state and federal legislation “because the future of American farming depends on reliable science-based regulation of important crop protection products – determined safe for use by the EPA”.The company additionally states on its website that without “legislative certainty”, lawsuits over its glyphosate-based Roundup and other weed killers can impact its research and product development and other “important investments”.Pingree said her efforts were aided by members of the Make America Healthy Again (Maha) movement who have spent the last few months meeting with congressional members and their staffers on this issue. She said her team reached out to Maha leadership in the last few days to pressure Republican lawmakers.“This is the first time that we’ve had a fairly significant advocacy group working on the Republican side,” she said.Last week, Zen Honeycutt, a Maha leader and founder of the group Moms Across America, posted a “call to action”, urging members to demand elected officials “Stop the Pesticide Immunity Shield”.“A lot of people helped make this happen,” Honeycutt said. “Many health advocates have been fervently expressing their requests to keep chemical companies accountable for safety … We are delighted that our elected officials listened to so many Americans who spoke up and are restoring trust in the American political system.”Pingree said the issue is not dead. Bayer has “made this a high priority”, and she expects to see continued efforts to get industry friendly language inserted into legislation, including into the new Farm Bill.“I don’t think this is over,” she said.This story is co-published with the New Lede, a journalism project of the Environmental Working Group

Forever Chemicals' Common in Cosmetics, but FDA Says Safety Data Are Scant

By Deanna Neff HealthDay ReporterSATURDAY, Jan. 3, 2026 (HealthDay News) — Federal regulators have released a mandated report regarding the presence of "forever chemicals" in makeup and skincare products. Forever chemicals — known as perfluoroalkyl and polyfluoroalkyl substances or PFAS — are manmade chemicals that don't break down and have built up in people’s bodies and the environment. They are sometimes added to beauty products intentionally, and sometimes they are contaminants. While the findings confirm that PFAS are widely used in the beauty industry, the U.S. Food and Drug Administration (FDA) admitted it lacks enough scientific evidence to determine if they are truly safe for consumers.The new report reveals that 51 forever chemicals — are used in 1,744 cosmetic formulations. These synthetic chemicals are favored by manufacturers because they make products waterproof, increase their durability and improve texture.FDA scientists focused their review on the 25 most frequently used PFAS, which account for roughly 96% of these chemicals found in beauty products. The results were largely unclear. While five were deemed to have low safety concerns, one was flagged for potential health risks, and safety of the rest could not be confirmed.FDA Commissioner Dr. Marty Makary expressed concern over the difficulty in accessing private research. “Our scientists found that toxicological data for most PFAS are incomplete or unavailable, leaving significant uncertainty about consumer safety,” Makary said in a news release, adding that “this lack of reliable data demands further research.”Despite growing concerns about their potential toxicity, no federal laws specifically ban their use in cosmetics.The FDA report focuses on chemicals that are added to products on purpose, rather than those that might show up as accidental contaminants. Moving forward, FDA plans to work closely with the U.S. Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) to update and strengthen recommendations on PFAS across the retail and food supply chain, Makary said. The agency has vowed to devote more resources to monitoring these chemicals and will take enforcement action if specific products are proven to be dangerous.The U.S. Food and Drug Administration provides updates and consumer guidance on the use of PFAS in cosmetics.SOURCE: U.S. Food and Drug Administration, news release, Dec. 29, 2025Copyright © 2026 HealthDay.

Lawsuit claims worker suffered ‘chemical exposure’ from sulfuric acid leak in Houston Ship Channel

According to the lawsuit filed Wednesday, Jeffery Lee Lawson claims he suffered from “burning lungs, shortness of breath, pain in his throat, nausea, dizziness and skin irritation” as a result of the chemical leak. 

Court According to the lawsuit filed Wednesday, Jeffery Lee Lawson claims he suffered from “burning lungs, shortness of breath, pain in his throat, nausea, dizziness and skin irritation” as a result of the chemical leak.  Kyle McClenagan | Posted on January 2, 2026, 10:13 AM (Last Updated: January 2, 2026, 11:01 AM) Gail Delaughter/Houston Public MediaPictured is an aerial view of activity on the Houston Ship Channel in May 2019.A worker who was on a tanker ship in the Houston Ship Channel during a sulfuric acid leak last week has filed a lawsuit accusing the owner of the facility where the leak occurred of being "grossly negligent." According to the lawsuit filed Wednesday, Jeffery Lee Lawson claims he suffered from "burning lungs, shortness of breath, pain in his throat, nausea, dizziness and skin irritation" as a result of the chemical leak. The leak occurred in the early morning of Saturday, Dec. 27, after an elevated walkway collapsed and ruptured a pipeline at the BWC Terminals facility in Channelview, east of Houston. According to Harris County Judge Lina Hidalgo, approximately 1 million gallons of sulfuric acid were released as a result.

At the time of the leak, Lawson was working as a tankerman on a ship about 500 feet from the BWC Terminals facility, according to the lawsuit. "At approximately 2 a.m., Mr. Lawson heard a loud crash and subsequently saw a large gas cloud being released from the terminal," the lawsuit claims. "No alarms, warnings, or notifications were provided by Defendants. Shortly thereafter, Mr. Lawson was enveloped by the toxic substance and began to suffer from immediate physical injuries." ProvidedA photo of the apparent sulfuric acid leak at the BWC Terminals facility near the Houston Ship Channel included in a lawsuit against the company.The lawsuit names BWC Terminals LLC and BWC Texas Terminals LLC as the defendants and accuses the company of over a dozen alleged "grossly negligent" acts, including several alleged safety failures and Occupational Safety and Health Administration (OSAH) violations. Sulfuric acid is a colorless, oily liquid that is highly corrosive. Exposure to it can cause skin burns and irritate the eyes, lungs and digestive system, according to the Centers for Disease Control and Prevention. It can also be fatal. In a statement to Houston Public Media on Friday, a BWC Terminals spokesperson declined to comment and said the company does not comment on pending litigation. "We remain committed to operating safely, responsibly, and in compliance with all applicable regulations," the spokesperson wrote in an email. The lawsuit is seeking damages for the alleged physical and mental harm caused by the leak, past and future medical expenses and lost wages. Lawson, a Harris County resident, is seeking over $1 million in damages, according to the lawsuit. Shortly after the leak, County Judge Hidalgo said during a news conference that two people were hospitalized and released, while 44 others were treated at the scene. Lawson was diagnosed with chemical exposure and inflammation of the lungs, according to the lawsuit. On Monday, BWC Terminals said in a statement that the majority of the sulfuric acid released went into a designated containment area, with an “unknown” amount entering the ship channel. The full extent of the possible environmental impact caused by the leak is currently unknown. No other lawsuits against BWC Terminals had been filed in Harris County as of Friday morning.

L.A. fire cleanups reports describe repeated violations, illegal dumping allegation

We reviewed thousands of pages of Army Corps of Engineering quality assurance reports for the January fire soil cleanup. The results were startling.

The primary federal contractor entrusted with purging fire debris from the Eaton and Palisades fires may have illegally dumped toxic ash and misused contaminated soil in breach of state policy, according to federal government reports recently obtained by The Times.The records depict harried disaster workers appearing to take dangerous shortcuts that could leave hazardous pollution and endanger thousands of survivors poised to return to these communities. The Federal Emergency Management Agency and the U.S. Army Corps of Engineers allocated $60 million to hire personnel to monitor daily cleanup operations and document any health and safety risks. The Times obtained thousands of government oversight reports that detail these federal efforts to rid fire-destroyed homes of toxic debris between February and mid-May. The records, which were obtained on a rolling basis over several months, include dozens of instances in which oversight personnel flagged workers for disregarding cleanup procedures in a way that likely spread toxic substances. The latest batch of reports — turned over to The Times on Dec. 1 — contained allegations of improper actions involving Environmental Chemical Corp., the primary federal contractor, and the dozens of debris-removal crews it supervised. For example, on April 30, federally hired workers were clearing fire debris from a burned-down home in the Palisades burn scar. According to the Army Corps of Engineers, after the last dump truck left, an official with Environmental Chemical Corp., a Burlingame, Calif., company hired to carry out the federal debris removal mission, ordered workers to move the remaining ash and debris to a neighboring property.The crew used construction equipment to move four or five “buckets” worth of fire debris onto the neighboring property. It’s unclear if that property was also destroyed in the Palisades fire, and, if so, whether it had been already remediated.“I questioned if this was allowable and then the crew dumped material into the excavator bucket and planned to move it on the lowboy with material in bucket,” a federal supervisor wrote in a report intended to track performance of contractors. “Don’t think this is allowed.” According to the report, the workers also left glass, ash and other fire debris on the property the crew had been clearing, because they “were in a rush to get to the next site.” Experts who reviewed the reports said the behavior described may amount to illegal dumping under California law. Other reports obtained by The Times describe federal cleanup workers, on multiple occasions, using ash-contaminated soil to backfill holes and smooth out uneven portions of fire-destroyed properties in the Palisades burn scar. If that were true, it would be a breach of state policy that says contaminated soil from areas undergoing environmental cleanup cannot be used in this way. The reports also cite multiple occasions where workers walked through already cleared properties with dirty boot covers, possibly re-contaminating them. The inspectors also reported crews spraying contaminated pool water onto neighboring properties and into storm drains, and excavator operators using toothed buckets that caused clean and contaminated soil to be commingled.“Obviously, there was some really good work done,” state Sen. Ben Allen (D-Pacific Palisades) said about the federal cleanup. “But it appears that we’ve got some folks who are knowingly breaking the law and cutting corners in their cleanup protocol. “We’ve got to figure out how widespread this was, and anybody who was responsible for having broken a law in this area needs to be held accountable.” The Army Corps did not respond to requests for comment. An ECC executive said that without information such as the properties’ addresses or parcel numbers, he could not verify whether the accusations made in the oversight reports were substantiated by the companies’ own investigations or if any issues raised by the inspectors were resolved. Such specifics were redacted in the version of the reports sent to The Times. “At a high level, ECC does not authorize the placement of wildfire debris or ash on neighboring properties, does not permit the use of contaminated material as fill, and operates under continuous [Army Corps] oversight,” said Glenn Sweatt, ECC’s vice president of contracts and compliance.Between February and September, the Army Corps responded to nearly 1,100 public complaints or other inquiries related to the federal fire cleanup. Over 20% of grievances were related to quality of work, according to the Army Corps assessment of complaints. Some of these complaints point to the same concerns raised by the inspectors. For example, a resident in the Eaton burn scar filed a complaint on June 19 that “crews working on adjacent properties moved fire debris and ash onto his property after he specifically asked them not to.” Other property owners in Altadena filed complaints that crews had left all sorts of fire debris on their property — in some cases, buried in the ground. The Army Corps or ECC ordered crews to go back and finish up the debris removal for some properties. Other times, the officials left the work and costs to disaster victims. A Palisades property owner complained on May 7 that after the Army Corps supposedly completed cleaning his property, he found “parts of broken foundation [that] were buried to avoid full removal.” He said it cost him $40,000 to hire a private contractor to gather up and dispose of several dumpsters of busted-up concrete. James Mayfield, a hazardous materials specialist and owner of Mayfield Environmental Engineering, was hired by more than 200 homeowners affected by the fires to remove debris and contaminated soil — including, in some cases, from properties already cleared by Army Corps contractors. When Mayfield and his workers excavated additional soil from Army Corps-cleared properties, he said they occasionally uncovered ash, slabs of burned stucco, and other debris. “All you have to do is scoop and you can see the rest of the house underneath the ground,” Mayfield said. “It was never cleared at all.” After January’s wildfires, local health authorities warned the soil could be riddled with harmful pollutants from burned-down homes and cars, including lead, a heavy metal that can cause irreversible brain damage when inhaled or ingested by young children.Soil testing has been standard practice after major wildfires in California since 2007. Typically, after work crews clear away fire debris and several inches of topsoil from burned-down homes, federal or state disaster officials arrange for the same contractors to test the soil for lingering contamination. If they find contamination above state benchmarks, they are required to excavate another layer of that soil and conduct additional rounds of testing.But the aftermath of the Eaton and Palisades fires has been different. The Federal Emergency Management Agency has repeatedly refused to pay for soil testing in California, insisting the practice is not necessary to remove any immediate threats after the fires. The Newsom administration unsuccessfully petitioned FEMA to reconsider conducting soil testing to protect returning residents and workers. But as pressure mounted on the state to fund soil testing, the California Environmental Protection Agency secretary downplayed public health risks from fire contamination.Indeed, the vast majority of wildfire cleanups in California are managed by state agencies. Since the January wildfires, California officials have been noticeably guarded when questioned about how the state will respond when the next major wildfire inevitably strikes.Asked whether the state will continue to adhere to its long-standing post-fire soil sampling protocols, the California Governor’s Office of Emergency Services wouldn’t directly answer whether it would pay for soil testing after future wildfires. Its director, Nancy Ward, declined to be interviewed.“California has the most advanced testing systems in the nation, and we remain committed to advocating for the safe, timely removal of debris after a wildfire,” an agency spokesperson said in a statement. “Protecting public health and the well-being of impacted communities remains the state’s foremost priority.”Some environmental experts and lawmakers worry that abandoning long-established wildfire protocols, like soil testing, may set a precedent where disaster victims will assume more costs and work to ensure that their properties are safe to return to and rebuild upon.U.S. Rep. Brad Sherman (D–Los Angeles) called for the Army Corps to review the results of large-scale soil testing initiatives, including data from USC, to determine which contractors were assigned to clean properties where heavy contamination persists. Such an analysis, he said, might help the federal government figure out which contractors performed poor work, so that they they aren’t hired in future disasters. “I’m going to press the Army Corps to look at where the testing indicates there was still contaminants and who is the contractor for that, to see whether there are certain contractors that had a high failure rate,” Sherman said.“I want to make sure they’re ... evaluating these contractors vis-à-vis the next disaster,” he added. “And, ultimately it’s in the testing.”Throughout much of Altadena and Pacific Palisades, thousands of empty lots are awaiting permits to rebuild. But many property owners fear the possibility of contamination. The Department of Angels, a community-led nonprofit formed after the January wildfires, surveyed 2,300 residents whose homes were damaged or destroyed by the Eaton and Palisades blazes. About one-third of respondents said they wanted testing but had not received it.“The government abandoned testing and left us on our own,” one victim wrote. “We have each had to find out what is the best route to test and remediate, but without standardization and consistency, we are a giant experiment.”
