Earth’s Best Baby Food Lawsuit: February 2026 Ruling and Next Steps

The Earth’s Best baby food lawsuit is part of a nationwide wave of cases claiming that heavy metals in commercial baby food caused autism and ADHD in children, but the litigation is on shaky ground after a federal judge in February 2026 excluded nearly all of the plaintiffs’ scientific experts. Thousands of families are still pursuing claims against Hain Celestial, the brand’s owner, though no case has yet reached a jury and no settlement has been announced.

What the Lawsuits Claim

Parents suing Earth’s Best allege that their children developed autism spectrum disorder or ADHD after eating baby food contaminated with arsenic, lead, cadmium, and mercury. The claims sit on several legal theories: that the products were defective, that Hain failed to warn parents about heavy metal content, that the company was negligent in its testing and quality practices, and that marketing the products as safe and organic misrepresented what was actually in the jars.¹

Much of the factual foundation comes from a February 2021 staff report by the U.S. House Subcommittee on Economic and Consumer Policy, which reviewed internal documents from major manufacturers including Hain. The report found that Earth’s Best finished products contained up to 129 parts per billion of inorganic arsenic, that ingredients tested as high as 309 ppb for total arsenic and 352 ppb for lead, that 102 ingredients exceeded 20 ppb of cadmium, and that Hain did not test for mercury at all. For comparison, the FDA allows just 10 ppb of arsenic, 5 ppb of lead, and 5 ppb of cadmium in bottled water.²

A follow-up report in September 2021 said Hain tested individual ingredients rather than finished products, a practice the subcommittee found underestimated actual heavy metal levels 100 percent of the time, with finished-product levels running 28 to 93 percent higher than ingredient testing predicted. The report also said Hain authorized “deviations” allowing use of ingredients that exceeded the company’s own 200 ppb internal thresholds for arsenic and lead.³

Earth’s Best is not the only defendant in the broader litigation. Beech-Nut, Gerber, Happy Family Organics, Plum Organics, Sprout Foods, and Walmart’s Parent’s Choice brand are also named across the various cases.⁴

Where the Cases Are Being Litigated

The bulk of the federal cases were consolidated in April 2024 into multidistrict litigation known as MDL 3101, In re: Baby Food Products Liability Litigation, before Judge Jacqueline Scott Corley in the U.S. District Court for the Northern District of California.⁵ Roughly 402 cases were pending in the MDL as of May 2026. The law firm Wisner Baum, which serves as co-lead trial counsel, says it represents over 8,000 families across the broader baby food litigation.⁶

Parallel state court cases are moving on their own tracks in California and elsewhere. There is also a separate standalone proceeding against Hain in the Eastern District of New York, In re Hain Celestial Heavy Metals Baby Food Litigation (Case No. 2:21-cv-00678), which remained active with filings as recent as April 2026.⁷

The February 2026 Ruling That Reshaped the Litigation

The federal cases hit a wall on February 27, 2026, when Judge Corley excluded seven of the eight expert witnesses the plaintiffs planned to use to prove that baby food can cause autism or ADHD. The ruling followed a four-day evidentiary hearing in December 2025 under the Daubert standard, which requires expert testimony to rest on reliable scientific principles.⁸

Judge Corley described the plaintiffs’ causation theory as “a series of extrapolations” built on a “hypothetical menu” of what a baby might eat, a model she found was “unduly results-driven” and had been constructed by plaintiffs’ counsel rather than drawn from real-world consumption data. “Plaintiffs have not identified any scientific studies of whether baby food, let alone defendants’ baby food, can cause ASD or ADHD,” she wrote.⁹

The lone survivor was neurologist Kevin Shapiro, who was allowed to testify only about the biological plausibility that heavy metals can cause autism and ADHD, a narrower question than whether specific baby food products actually do.⁹ Because product liability claims generally cannot go to a jury without expert testimony establishing that a product can cause the alleged harm, the exclusion put the MDL cases in serious jeopardy.

A week earlier, on February 20, 2026, Los Angeles Superior Court Judge Lawrence Riff granted summary judgment to Hain and other manufacturers in a separate state case involving similar autism and ADHD claims. Judge Riff excluded the plaintiffs’ key toxicology expert under California’s Sargon standard, finding the methodology could not isolate exposure attributable to any specific defendant as opposed to other manufacturers or environmental sources.¹⁰ Plaintiffs are expected to appeal.

The Underlying Causation Fight

Plaintiffs cite research linking heavy metal exposure to neurodevelopmental harm, including a 2017 Nature Communications study on early-life lead exposure and autism risk and work in Environmental International connecting arsenic exposure to ADHD risk and cadmium exposure to both conditions.¹¹ They also lean on the 2021 congressional reports and a May 2025 CDC report on lead exposure.¹²

Defendants and, so far, the federal court have identified what Judge Corley called an “analytical gap” between studies showing heavy metals are neurotoxic in general and the specific claim that baby food consumption causes autism or ADHD. Other exposure sources such as lead paint, contaminated water, and soil complicate any attempt to trace a child’s condition to a particular jar of food. A California Superior Court judge did approve expert testimony on the link in 2022, but the 2026 rulings moved sharply the other way.¹¹

The Supreme Court’s Palmquist Decision

One piece of good news for plaintiffs came from the U.S. Supreme Court. In The Hain Celestial Group, Inc. v. Palmquist, No. 24-724, decided February 24, 2026, the Court ruled unanimously that a federal district court had improperly kept jurisdiction over a baby food case after erroneously dismissing Whole Foods, a nondiverse defendant.¹³

Justice Sotomayor’s opinion held that when a court incorrectly dismisses a nondiverse party and that error is reversed on appeal, diversity jurisdiction is destroyed and the entire federal judgment must be vacated. The Court rejected Hain’s argument that Federal Rule of Civil Procedure 21 could be used to drop Whole Foods and preserve federal jurisdiction, calling the plaintiff the “master of the complaint” with the right to choose state court.¹³ Justice Thomas joined but wrote separately to question whether the broader “improper joinder” doctrine warrants re-examination.¹⁴

The practical effect is that some cases Hain had been litigating in federal court must return to state court, where evidentiary rules and jury pools may produce different outcomes than the federal MDL has so far.

Hain Celestial’s Position

Hain Celestial, headquartered in Hoboken, New Jersey and traded on NASDAQ under HAIN, describes Earth’s Best as a pioneer in organic baby food with more than 40 years on the market.¹⁵ The company has not settled the litigation and has continued to defend its safety practices.

Earth’s Best now publishes product testing information on its website, including a tool that lets parents look up heavy metal results for specific products. The company says it tests both raw ingredients and finished products for lead, arsenic, cadmium, and mercury, with finished-product samples sent to a third-party lab, and states that its internal limits comply with the FDA’s “Closer to Zero” action levels and European Union regulations.¹⁶ Consumer Reports has recognized Earth’s Best as a top-scoring company for transparency in disclosing heavy metal testing results.¹⁷

When Consumer Reports independently tested Earth’s Best Organic Sweet Potatoes, however, it reported “concerning levels of lead” and concluded the samples likely exceeded California’s Proposition 65 threshold of 0.5 micrograms of lead per daily serving. Hain responded that it believed its products complied with California law.¹⁸

What Happens Next

As of mid-2026, no settlement has been reached, no bellwether trial dates have been set in the federal MDL, and no plaintiff has won a verdict.¹⁰

Co-lead plaintiffs’ counsel R. Brent Wisner said his team was evaluating “appropriate next steps” and that an appeal “of some sort” would be pursued after the expert ruling. Judge Corley scheduled an April 2, 2026 hearing to discuss the path forward.⁸ Wisner Baum has indicated it is preparing to take the first toxic baby food case to trial in 2027, and a separate California state court trial is expected sometime in 2026.¹⁹

Whether the broader litigation survives will depend on the appeals and on whether plaintiffs can develop stronger expert testimony that ties specific baby food products, rather than heavy metal exposure in general, to autism and ADHD. State courts, particularly after Palmquist, may offer plaintiffs a more workable venue than the federal MDL where the causation theory has already been rejected.
