Judge Dismisses Autism and ADHD Claims Against Major Baby Food Brands

A federal judge in California has granted partial summary judgment to major baby food manufacturers, rejecting claims that heavy metals in their products caused children to develop autism spectrum disorder and attention-deficit hyperactivity disorder. The ruling significantly narrows a sweeping multidistrict class action brought by parents across the country.

U.S. District Judge Jacqueline Corley determined that the families suing the companies failed to present acceptable proof showing a general scientific link between the foods and those developmental conditions. In an eight-page decision, Judge Corley noted that the plaintiffs lacked the proof needed to satisfy general causation, writing, “Plaintiffs have presented no admissible evidence supporting the general causation element of their claims.”

Why the Court Tossed the Autism and ADHD Allegations

The litigation centers on allegations that commercial baby foods made and sold by companies including Gerber, Whole Foods, Nestle, Walmart, and 10 other businesses contained toxic heavy metals such as lead, arsenic, mercury, cadmium, and aluminum. In a consolidated master complaint filed in 2024, parents alleged the companies knowingly sold contaminated products while aware that heavy metals can cause neurological harm and brain damage.

Judge Corley had previously permitted the lawsuit to proceed into general discovery. This phase was designed specifically to determine whether evidence could demonstrate, at least in theory, that the products were linked to neurodevelopmental disorders. After examining the evidence gathered by the plaintiffs, the court concluded that the legal threshold for general causation had not been met.

For their defense, the food companies maintained that their items are safe for children. They argued that heavy metals occur naturally in soil and water and insisted there is no evidence establishing that trace amounts of those substances cause autism or ADHD. The recent ruling follows an earlier 2025 decision in which Judge Corley dismissed claims against three companies and two Nestle subsidiaries because they were not involved in making or selling products in California.

Certain Heavy Metal Claims Are Still Moving Forward

Despite the setback regarding autism and ADHD, the litigation is not completely over for the manufacturers. Judge Corley pointed out that claims alleging other types of harm survive for the time being. Those allegations include cognitive damage such as IQ loss and learning disabilities, which were not the focus of the initial general discovery order.

Additionally, the summary judgment decision does not apply to legal claims involving infant formula. As a result, parents pursuing claims centered on formula or on cognitive injuries other than autism and ADHD can still continue their cases in court.

The plaintiffs had grounded many of their claims in a 2021 congressional report. That report concluded commercial baby foods had notable levels of heavy metals and warned that exposure could result in permanent decreases in IQ, long-term developmental harm, and other behavioral challenges.

What the Ruling Means for Affected Families

This decision directly affects parents who filed lawsuits claiming that store-bought baby food caused a child to develop autism or ADHD. Under this ruling, those specific claims cannot move forward against the named manufacturers in this federal proceeding.

However, families asserting that their children suffered from learning disabilities, decreased IQ, or complications stemming from infant formula are not barred by this order. These consumers should continue monitoring court developments as future proceedings examine evidence tied to those separate injuries.

When dealing with complex toxic exposure or product liability cases, consulting an attorney can help parents understand how evolving court rulings apply to their child’s specific diagnosis and legal options.
