Baby Food Autism Lawsuit Ruling: Judge Ends Autism and ADHD Claims in MDL 3101, IQ Claims Survive

The baby food autism lawsuit ruling came down on Wednesday, October 14, 2026, when U.S. District Judge Jacqueline Scott Corley granted partial summary judgment to Gerber, Walmart, Beech-Nut and the other manufacturers in MDL No. 3101 on every claim that lead and arsenic in their products caused autism or ADHD. The reason is a single missing element: after her February 2026 order excluding the plaintiffs' causation experts, the court held that plaintiffs "have presented no admissible evidence supporting the general causation element of their claims," so the core injury theory of a roughly 500-case federal mass tort is over unless an appellate court revives it.

The order is short, eight pages by the accounts of those who have read it, but it is not the end of the litigation. Claims alleging other injuries, such as IQ loss and learning disabilities, survive for now because the court's general causation phase never tested them, and the ruling does not reach claims arising from infant formula. On the same day, Texas Attorney General Ken Paxton announced a consumer-protection suit against Gerber and Nestlé USA that does not depend on proving that anyone was injured at all. Practitioners now have a federal MDL with its headline theory gone, a residual docket of narrower claims, and a parallel state enforcement track pointed at the same products.

This article explains what the court decided and why, which defendants benefit, what remains pending, how and when plaintiffs can appeal, how the result compares with the Tylenol autism litigation, and what the ruling means for claimants' counsel, defendants, litigation funders and state-court venues.

What the judge decided in the baby food autism lawsuit ruling

The motion before Judge Corley asked a narrow question. The defendants, a group that includes Gerber Products Co., Beech-Nut Nutrition Co., Walmart Inc., Hain Celestial Group (maker of Earth's Best), and, per a June 2026 brief, Amazon, Whole Foods and Campbell's, argued that every plaintiff alleging autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD) must prove General Causation as an element of each product liability theory, and that after the court's Rule 702 order there was no admissible evidence left to carry that burden.

The court agreed. Summary judgment under Federal Rule of Civil Procedure 56 is proper when there is no genuine dispute of material fact and the movant is entitled to judgment as a matter of law. Where general causation is an element plaintiffs must prove with expert testimony, and the expert testimony has been excluded, there is no fact for a jury to resolve. That is the whole syllogism, and it is why the order could be so brief.

The plaintiffs had tried to avoid that outcome. In opposition papers reported in mid-2026, they argued that a factual dispute still existed over how much exposure children actually had to specific products, and they leaned on the one expert who survived the February order. The court was not persuaded that either point supplied admissible proof that lead or arsenic at baby food exposure levels can cause autism or ADHD in the general population, which is what general causation asks.

Judge Corley previewed the result. At an August 13, 2026 hearing, she signaled that she was likely to grant the motion as to a significant portion of the claims, while questioning whether neurological injuries other than ASD and ADHD were even within the motion's scope. She also told plaintiffs that if they intended to pursue injuries beyond autism and ADHD, those injuries had to be identified in their complaints; it was not the court's job to infer which symptoms might be related to the two named conditions. The October 14 order tracks those remarks closely.

Why the court ruled against the baby food autism plaintiffs

The summary judgment ruling is the second half of a two-step sequence that began with a Daubert Challenge. Over five days of hearings from December 8 to 12, 2025, the court heard the defendants' motions to exclude the plaintiffs' general causation experts under Federal Rule of Evidence 702, which since its December 2023 amendment requires the proponent to show by a preponderance of the evidence that an expert's opinion reflects a reliable application of reliable methods.

On February 27, 2026, Judge Corley excluded all but one of the plaintiffs' general causation opinions. Secondary accounts differ on the arithmetic (five of six experts, seven of eight opinions), but they agree on the result and on the survivor: Dr. Kevin Shapiro, whose testimony was permitted only on biological plausibility, the proposition that lead and arsenic are capable of affecting neurodevelopment. Biological plausibility is a necessary building block of a causation case, but it is not a general causation opinion; it does not say that the exposure at issue causes the disease at issue.

Three lines of reasoning drove the exclusions, according to the order's reported text and published analyses of it:

• The exposure estimates rested on hypothetical menus. To estimate how much lead and arsenic a child would ingest, a dietitian expert used model baby food "menus." The court found that plaintiffs' counsel, not the expert, had built those menus, and that the expert could not explain how the products were chosen. Commentators described the court's view as treating the menus as a black box.
• The consumption assumptions were a poor fit. The expert's report treated a consumption pattern as plausible if it applied to at least one child in the United States. The court found that standard a poor fit for general causation, which asks whether exposure at levels people realistically experience can cause the disease.
• The literature did not bridge the gap. The experts relied heavily on studies of lead and arsenic exposure from all sources, not on studies linking baby food consumption to ASD or ADHD. The court noted that no published study ties baby food consumption directly to either condition, and found that the cited studies did not show a significant association at the relevant exposure levels.

Once those opinions were out, summary judgment followed almost mechanically. The defendants filed their motion in May 2026, arguing that plaintiffs' failure to offer admissible general causation testimony sank every autism and ADHD claim regardless of the legal theory pleaded: design defect, manufacturing defect, negligence or Failure to Warn. The October 14 order accepted that framing.

Which baby food companies won the ruling?

The ruling benefits every defendant that joined the motion as to every autism and ADHD claim pending against it in the MDL. Reporting on the order identifies Gerber and Walmart by name; the moving group, as described in mid-2026 briefing, also includes Beech-Nut, Hain Celestial, Whole Foods, Amazon and Campbell's. Earlier rulings had already narrowed the defendant list: an October 2025 order dismissed Danone North America, Sun-Maid Growers of California and two of Nestlé's international subsidiaries on pleading grounds.

The companies have consistently denied the allegations. Gerber's public position is that its products undergo rigorous testing and meet U.S. Food and Drug Administration limits for heavy metals, and it has cited the MDL record for the point that no peer-reviewed study supports a link between baby food and autism or ADHD. Hain Celestial has described its baby foods in securities filings as safe and properly labeled.

It is worth being precise about what the defendants did not win. The order does not find that their products were free of heavy metals, that their testing practices were adequate, or that they made no misleading statements. It decides only that, on this record, the plaintiffs cannot prove the scientific link the autism and ADHD claims require.

What baby food claims are still pending after the ruling?

Three categories survive the October 14 order, at least for now:

1. Other neurodevelopmental injuries. Claims alleging IQ loss, learning disabilities and similar harms remain. The court's reasoning was procedural rather than a merits endorsement: the general causation phase was organized around ASD and ADHD, so the defendants' motion and the expert record did not squarely address those injuries. Defendants can be expected to seek a second general causation phase, and the August hearing suggests the court will hold plaintiffs to injuries actually pleaded in their complaints.
2. Infant formula claims. The order does not apply to claims involving the consumption of infant formula, which present different products, different exposure data and, in some cases, different defendants.
3. Cases outside the MDL. State-court cases are not bound by a federal Rule 702 ruling. That includes the Texas case at the center of Hain Celestial Group, Inc. v. Palmquist, in which the Supreme Court unanimously held, in an opinion by Justice Sonia Sotomayor, that a federal judgment for Hain had to be vacated because the district court wrongly dismissed the nondiverse retailer, Whole Foods, after removal. That family's case returns to Texas state court. In California, by contrast, a Los Angeles Superior Court judge has already granted summary judgment to Hain Celestial and other makers in an autism case after excluding the plaintiffs' toxicology expert under California's Sargon standard, a result the plaintiffs have said they will appeal.

Within the MDL, the practical effect is triage. The MDL had grown steadily through 2026: 473 cases on July 1, 478 on August 3, 483 in September and 497 as of October 7, according to the tracker maintained by co-lead counsel's firm. Most of those cases, by the plaintiffs' own descriptions, allege autism or ADHD. Each case now has to be sorted into one of three buckets: autism or ADHD only (subject to judgment), additional pleaded injuries (live, but facing a likely second causation fight), or formula exposure (outside this order).

Can the baby food plaintiffs appeal the ruling?

Yes, but not immediately as of right. An order granting partial summary judgment in an MDL is interlocutory: it disposes of some claims but leaves others pending, so it is not a "final decision" appealable under 28 U.S.C. § 1291. Plaintiffs have three realistic paths to the Ninth Circuit.

• Rule 54(b) certification. The district court may direct entry of final judgment on fewer than all claims or parties if it expressly determines that there is no just reason for delay. In an MDL, the cleanest candidate is an individual case that pleads only autism or ADHD; judgment in that case resolves every claim in it and can be appealed. Many MDL courts enter judgment in such cases precisely so that the circuit can review the Rule 702 ruling while the rest of the docket waits.
• Final judgments case by case. Even without certification, a plaintiff whose complaint alleges only ASD or ADHD will eventually face a final judgment, which is appealable on its own.
• Interlocutory certification under 28 U.S.C. § 1292(b). The court may certify a controlling question of law on which there is substantial ground for difference of opinion. This is a harder fit, because Rule 702 rulings are reviewed for abuse of discretion and are usually treated as fact-bound rather than as pure questions of law.

On appeal, the Ninth Circuit would review the February exclusion order for abuse of discretion, a deferential standard, and the summary judgment order de novo. In practice, the summary judgment ruling rises or falls with the expert ruling.

No appeal had been reported as of October 17, 2026, and none could be noticed until a judgment is entered.

How the baby food ruling compares with the Tylenol autism MDL

The closest template for an appeal is the acetaminophen (Tylenol) litigation, where a district court excluded all of plaintiffs' autism and ADHD causation experts and the Second Circuit, on July 13, 2026, reinstated three of the five. The comparison is instructive, not predictive: the cases arise in different circuits, involve different science, and turned on different methodological flaws.

Feature	Baby food MDL No. 3101	Acetaminophen MDL No. 3043
Court	N.D. Cal. (Corley, J.); appeal to Ninth Circuit	S.D.N.Y. (Cote, J.); appeal to Second Circuit
Alleged exposure	Lead and arsenic in baby food (infancy)	Acetaminophen use in pregnancy (prenatal)
Injuries at issue	ASD and ADHD	ASD and ADHD
Expert outcome in trial court	All but one general causation opinion excluded (Feb. 27, 2026); surviving expert limited to biological plausibility	All plaintiffs' general causation experts excluded (December 2023)
Central flaw identified	Exposure estimates built on counsel-designed hypothetical menus; literature on lead and arsenic generally, not baby food	Methodology for weighing epidemiology under Bradford Hill factors
Dispositive ruling	Partial summary judgment, Oct. 14, 2026	Summary judgment and dismissal of more than 500 cases
Appellate status	No appeal yet; order is interlocutory	Second Circuit reinstated three of five experts (July 13, 2026); rehearing petition pending

The difference that may matter most is the nature of the flaw. The Second Circuit's acetaminophen opinion treated the district court's critique of how experts weighed published epidemiology as something closer to a dispute for the jury. The baby food court's central objection is more foundational: that the exposure inputs themselves, the amounts of lead and arsenic children supposedly ingested, were not reliably derived. Appellate courts tend to be more comfortable affirming exclusions grounded in unreliable data inputs than exclusions grounded in disagreement over how to read a body of studies.

What is the Texas lawsuit against Gerber and Nestlé about?

Texas sued Gerber Products Co. and Nestlé USA, Inc. under the Texas Deceptive Trade Practices Act (DTPA) in the district court of Collin County, alleging that the companies misled parents about heavy metals in Gerber baby food. Several outlets report the petition was filed on October 9, 2026; the Attorney General's office announced it on October 14, the same day the MDL order issued.

According to the Attorney General's announcement, Gerber's own testing showed that from 2017 through 2019 it used 67 batches of rice flour containing more than nine times the arsenic the federal government allows in bottled water, along with carrots and sweet potatoes that exceeded cadmium and lead benchmarks by wide margins. The state contrasts Gerber's conduct with Beech-Nut's 2021 recall of its infant rice cereal after arsenic testing, alleging that Gerber issued no recall or warning and kept selling. It also targets labeling: Gerber now discloses test results behind a QR code, but the state says the front-of-package safety messaging did not change. The suit seeks civil penalties of up to $10,000 per violation, which the petition says could exceed $10 million in total, plus restitution and costs. The case grows out of civil investigative demands the office served on Gerber and Plum Organics in August 2025.

The legal significance for MDL watchers is that a DTPA enforcement action does not require proof that the products caused autism, ADHD or any injury. The state must prove a false, misleading or deceptive act or practice, and civil penalties do not depend on individual harm. The federal Rule 702 ruling therefore has little direct bearing on Texas's case, although Gerber can be expected to cite the MDL record on the absence of a proven health effect when arguing materiality and penalties.

A separate private suit reported on October 16, 2026, filed in a Florida federal court against Gerber and Nestlé USA on behalf of a child with ASD, alleges that the companies knowingly sold contaminated products. Absent a tag-along transfer into MDL No. 3101, such a case would face the same general causation problem in front of a different judge, with the February order as persuasive authority.

Does the ruling mean baby food heavy metals are safe?

No. The baby food autism lawsuit ruling decides a narrower question: whether these plaintiffs offered admissible scientific evidence that lead and arsenic, at the levels found in baby food, can cause autism or ADHD. The court held they did not. It did not find that heavy metals in baby food are harmless, and lead in particular has no known safe exposure level for children according to public health authorities.

Regulators are working on the exposure question on a separate track. In January 2025, the FDA issued final guidance setting voluntary action levels for lead in processed foods intended for babies and young children, at 10 parts per billion for most products and 20 parts per billion for single-ingredient root vegetables and dry infant cereals, as part of its "Closer to Zero" program. California's AB 899 requires baby food makers selling in the state to test for arsenic, cadmium, lead and mercury and, since January 1, 2025, to make results available to consumers, which is why QR-code disclosures now appear on many labels. Those regimes concern exposure reduction and disclosure, not proof of disease causation in a courtroom.

What the baby food autism lawsuit ruling means for claimants' counsel, defendants and funders

For claimants' counsel. Inventory triage is the immediate task. Cases pleading only ASD or ADHD face judgment; counsel should expect the court to enter it and should consider whether to request Rule 54(b) judgment in representative cases to get the February order before the Ninth Circuit quickly. Cases with independently pleaded IQ-loss or learning-disability injuries remain live, but the August 13 hearing signals that unpleaded injuries will not be rescued, and that any second general causation phase will scrutinize exposure methodology at least as hard as the first. Firms carrying formula cases should map which defendants and products are actually at issue. Intake of new autism-only claims in federal court now carries an obvious risk; a client who can show an injury other than ASD or ADHD presents a different case. Attention to the Statute of Limitations for children's claims, often tolled during minority, will affect how long counsel can wait for appellate clarity.

For defendants. The result validates a phased MDL structure that front-loads general causation before case-specific discovery, the same sequencing that ended the Zantac MDL. The next priorities are likely to be a motion to apply the same reasoning to non-ASD neurological injuries, a request for orders requiring each plaintiff to specify injuries in a Plaintiff Fact Sheet (PFS) or amended short-form complaint, and coordination with state-court defense teams so that the February order can be offered as persuasive authority in parallel cases. Consumer-protection exposure is a separate risk: the Texas DTPA case shows that state enforcers can pursue the same testing documents without any causation burden.

For litigation funders. Portfolios built on autism and ADHD baby food claims have been marked down by this ruling in all but name. The value that remains sits in appellate optionality, the residual injury categories, and any state-court cases that can survive under state evidence rules. Funders will want to know how much of a firm's inventory is autism-only, and whether a Third-Party Litigation Funding agreement allows the firm to drop cases that no longer meet its own screening criteria.

For state courts and state enforcers. State-court plaintiffs are not bound by MDL No. 3101, but defendants will press the February and October orders as persuasive authority, especially in jurisdictions that follow the federal Rule 702 standard. States like Texas, by contrast, have a path that does not require causation proof and that targets testing and labeling conduct directly.

What the baby food autism lawsuit ruling signals for other autism and ADHD mass torts

The baby food autism lawsuit ruling joins a run of federal Multidistrict Litigation (MDL) proceedings in which the outcome turned on general causation rather than on liability facts. Courts have increasingly used Rule 702, as amended in 2023, to require that causation experts show reliable exposure data and a reliable bridge from the literature to the specific product, rather than relying on general toxicity. For a Mass Tort built on a neurodevelopmental injury with many contributing factors, that bridge is hard to build, and the cost of building it is borne before any Bellwether Trial is set.

The counter-current is appellate. The Second Circuit's acetaminophen decision showed that circuit courts will reverse exclusions they view as weighing the evidence rather than policing methodology. Whether the Ninth Circuit sees the baby food menus problem as methodology or as weight is likely to decide whether the autism and ADHD claims come back.

FAQ

What did the judge decide in the baby food autism lawsuit?

On October 14, 2026, Judge Jacqueline Scott Corley granted partial summary judgment to the baby food manufacturers in MDL No. 3101 on all claims that lead and arsenic in their products caused autism or ADHD, holding that plaintiffs presented no admissible evidence of general causation.

Is the baby food autism lawsuit over?

The autism and ADHD claims in the federal MDL are over unless reversed on appeal, but the MDL itself continues: claims for IQ loss, learning disabilities and other pleaded injuries survive for now, infant formula claims are unaffected, and state-court cases and the new Texas enforcement action proceed separately.

Why did the court rule against the plaintiffs?

Because the court had already excluded all but one of the plaintiffs' general causation opinions in February 2026, finding the exposure estimates relied on hypothetical menus designed by counsel and on studies of lead and arsenic generally rather than baby food, there was no admissible evidence left on an element plaintiffs must prove.

Which baby food companies won the ruling?

The moving defendants, a group reported to include Gerber, Walmart, Beech-Nut, Hain Celestial (Earth's Best), Whole Foods, Amazon and Campbell's, won judgment on the autism and ADHD claims pending against them in the MDL.

Can the baby food plaintiffs appeal?

Yes, once a final judgment is entered, either in individual autism-only cases or through Rule 54(b) certification; the Ninth Circuit would review the February expert ruling for abuse of discretion, the standard under which the Second Circuit reinstated experts in the Tylenol autism MDL in July 2026.

What is the Texas lawsuit against Gerber and Nestlé about?

Texas alleges under its Deceptive Trade Practices Act that Gerber and Nestlé USA misled parents about heavy metals, citing 67 rice-flour batches from 2017 to 2019 with more than nine times the bottled-water arsenic limit, and seeks up to $10,000 per violation; it does not need to prove that anyone was injured.
