Litigation status reviewed: August 18, 2026

What is necrotizing enterocolitis (NEC)?

Necrotizing enterocolitis, commonly called NEC, is a serious intestinal disease that primarily affects premature and very low birth weight infants.

NEC involves inflammation and injury to the intestinal tissue. In severe cases, portions of the intestine can become damaged or die.

The condition may require:

• Intensive medical treatment
• Antibiotics
• Stopping enteral feeding
• Feeding through an IV
• Surgery
• Removal of damaged intestine
• Long-term nutritional support

Severe NEC can cause lasting complications or death.

The federal government's NEC working group describes prematurity as the primary risk factor for developing NEC. (NICHD)

What is the NEC baby formula lawsuit about?

The litigation involves families who allege that premature infants developed NEC after receiving certain cow’s-milk-based premature infant formulas or fortifiers.

Plaintiffs generally allege that manufacturers:

• Knew or should have known about research showing different NEC rates among premature infants fed human milk versus formula.
• Failed to adequately warn physicians, hospitals, or parents about alleged risks.
• Marketed cow’s-milk-based premature infant nutrition products without sufficient warnings.
• Designed or sold products that plaintiffs allege created an unreasonable risk for vulnerable premature infants.

The manufacturers dispute those allegations.

Abbott and Mead Johnson maintain that their products do not cause NEC and that specialized premature infant nutrition products play an important role when a mother’s own milk or donor human milk is unavailable or insufficient.

That disagreement over causation, warnings, product design, and available feeding alternatives is central to the litigation.

Which baby formula companies are involved?

The principal defendants in MDL 3026 are associated with two major premature-infant nutrition brands:

Abbott Laboratories

Abbott manufactures Similac products, including specialized formulas used for premature or low birth weight infants.

Mead Johnson

Mead Johnson, part of Reckitt, manufactures Enfamil products, including premature-infant formulas and fortification products.

The litigation concerns specific premature infant nutrition products and should not be confused with ordinary retail infant formula generally used by healthy full-term infants.

Is this the same as the Abbott infant formula recall litigation?

No.

This distinction is important.

MDL 3026 concerns allegations that certain premature infant nutrition products contributed to NEC.

A separate federal proceeding, MDL 3037, In re: Recalled Abbott Infant Formula Products Liability Litigation, concerns allegations arising from recalled infant formula associated with Abbott’s Sturgis, Michigan manufacturing facility.

The JPML lists the two as separate proceedings. As of August 3, 2026, MDL 3037 had 14 pending actions, while MDL 3026 had 825 pending actions. (JPML)

The NEC litigation does not depend on allegations that the premature infant formulas were contaminated.

Is there an NEC baby formula MDL?

Yes.

Federal cases are centralized in:

In re: Abbott Laboratories, et al., Preterm Infant Nutrition Products Liability Litigation

MDL No. 3026

U.S. District Court for the Northern District of Illinois

The proceeding is overseen by U.S. District Judge Rebecca R. Pallmeyer. (Northern District Court IL)

As of August 3, 2026, the Judicial Panel on Multidistrict Litigation reported:

• 825 pending actions
• 1,035 total actions historically

in MDL 3026. (JPML)

Is the NEC baby formula lawsuit a class action?

No.

MDL 3026 is a multidistrict litigation, not a class action.

In an MDL:

• Individual lawsuits remain separate claims.
• Similar federal cases are coordinated before one judge.
• Common discovery and expert issues can be handled together.
• Bellwether cases may test particular legal and factual issues.
• Individual cases may settle, be dismissed, go to trial, or return to their original courts.

Each infant’s case may involve different:

• Gestational age
• Birth weight
• Feeding history
• Formula or fortifier
• Amount of human milk received
• Medical condition
• NEC severity
• Treatment
• Long-term complications
• Applicable state law

There is no automatic equal outcome for every family in the MDL.

What does the federal government say about formula and NEC?

This is the most important scientific nuance on the page.

In 2024, an NIH-convened NEC Working Group completed an extensive review of the evidence involving premature infants, feeding practices, and NEC.

FDA, CDC, and NIH later issued a consensus statement highlighting two key conclusions:

1. There is no conclusive evidence that preterm infant formula causes NEC.
2. There is strong evidence that human milk is protective against NEC. (U.S. Food and Drug Administration)

The agencies also emphasized that preterm birth itself is the primary risk factor for NEC and that important scientific gaps remain. (U.S. Food and Drug Administration)

That distinction matters.

A lower NEC rate among human-milk-fed infants does not automatically prove that formula itself is a toxic cause of NEC.

Does human milk reduce the risk of NEC?

Yes.

The evidence that human milk is protective against NEC is substantially stronger than the evidence that formula independently causes the disease.

The NIH NEC Working Group concluded that, as the proportion of mother’s milk in a premature infant’s diet increases, NEC risk generally decreases. It also reviewed evidence showing lower NEC rates among premature infants receiving donor human milk compared with preterm formula when the mother’s own milk was unavailable. (NICHD)

In one randomized trial reviewed by the working group, NEC developed in:

• 4.2% of infants assigned to donor human milk
• 9% of infants assigned to formula

The infants were extremely premature, and some in both groups also received limited amounts of their own mother’s milk. (NICHD)

The working group concluded that human milk significantly reduced—but did not eliminate—the risk of NEC. (NICHD)

Does formula cause NEC?

There is no conclusive scientific answer establishing that preterm infant formula itself causes NEC.

The NIH working group stated that available research supports the conclusion that human milk is protective, while the data regarding whether preterm formula itself causes NEC remain inconclusive. (NICHD)

That is different from saying feeding choice does not matter.

Studies consistently show different NEC rates among premature infants receiving different diets.

The unresolved scientific question is why those rates differ.

Possible explanations include protective components in human milk, differences in the premature gut microbiome, immune development, feeding practices, underlying prematurity, cow’s-milk protein exposure, or combinations of factors.

Research continues.

What did the NIH NEC Working Group find about cow’s-milk-based fortifiers?

The evidence regarding cow’s-milk-derived fortifiers is less certain than the evidence supporting human milk generally.

Very low birth weight infants often need additional calories, protein, minerals, and other nutrients beyond what unfortified human milk provides.

That means human milk may be fortified with either:

• A human-milk-derived fortifier, or
• A bovine/cow’s-milk-derived fortifier.

The NIH Working Group concluded that relatively few rigorous studies have directly compared these fortifiers and that available studies have often been too small to draw definitive conclusions about NEC risk. (NICHD)

Some studies have found lower NEC rates with human-milk-derived fortifiers, while others have not found a statistically significant difference.

Why do premature infants sometimes need formula or fortifier?

Premature infants have unusually high nutritional needs.

They may require additional:

• Calories
• Protein
• Minerals
• Vitamins
• Other nutrients

to support rapid growth and development outside the womb.

A mother may also be unable to produce enough breast milk to fully meet the infant’s nutritional needs.

The NIH Working Group states that when sufficient mother’s milk is unavailable, pasteurized donor human milk is generally preferred, followed by premature infant formula. Human milk itself often still requires fortification for very low birth weight infants. (NICHD)

FDA also recognizes specialized premature formulas designed with additional calories and nutrients for premature infants. (U.S. Food and Drug Administration)

These products therefore exist because premature infants can face serious risks from inadequate nutrition as well as from NEC.

What are Similac and Enfamil NEC lawsuits alleging?

Claims generally involve premature infants who received products associated with Similac or Enfamil and later developed NEC.

Depending on the case, plaintiffs may allege:

• Failure to warn
• Defective design
• Negligence
• Product liability
• Breach of warranty
• Other state-law claims

Some cases focus heavily on whether manufacturers should have warned physicians about observed differences in NEC risk between human-milk diets and cow’s-milk-based premature infant products.

The defendants argue that healthcare professionals have long understood the protective benefits of human milk and that current evidence does not establish that their formulas cause NEC.

What happened to the first federal bellwether cases?

The first group of federal bellwether cases produced important defense rulings before reaching a jury.

For example, in Mar v. Abbott Laboratories, the district court granted summary judgment to Abbott in a case involving a premature infant who developed NEC after receiving Similac Special Care 24.

On July 24, 2026, the U.S. Court of Appeals for the Seventh Circuit affirmed that judgment.

The appellate court concluded that the plaintiff had not shown that the warning she argued Abbott should have provided would have prevented the infant’s death. (Seventh Circuit Court)

That decision did not determine whether every other NEC claim succeeds or fails. It turned on the evidence and legal requirements applicable to that individual case.

Is a federal NEC bellwether trial happening now?

Yes.

As of this page’s litigation review on August 18, 2026, the Northern District of Illinois’ official calendar shows:

Inman v. Mead Johnson & Company, LLC

Case No. 1:22-cv-03737

Jury Trial — August 18, 2026

before Judge Rebecca Pallmeyer. (Northern District Court IL)

Because the trial is underway as this page is being reviewed, BenefitKarma should not speculate about its outcome.

This status should be updated after the court records a verdict or other resolution.

Have state-court NEC cases gone to trial?

Yes.

NEC litigation has also proceeded separately in state courts, producing mixed results.

For example:

• In 2024, a Missouri jury returned a substantial verdict against Abbott in a case involving an infant who developed NEC.
• In June 2026, an Illinois appellate court reversed an earlier $60 million verdict against Mead Johnson and ordered a new trial because of an error in the jury instructions. (Reuters)
• In July 2026, a Missouri jury returned a defense verdict for Mead Johnson in another NEC case. (Reuters)
• In April 2026, a Chicago jury awarded $70 million to four families in a separate trial involving Abbott. Abbott said it would appeal. (Reuters)

These differing results demonstrate why a verdict in one NEC case does not determine the outcome of another.

What happened to the $495 million Abbott verdict?

In 2024, a Missouri jury awarded approximately $495 million in compensatory and punitive damages in a case involving allegations that Abbott’s premature infant formula contributed to NEC.

The litigation continued through appeal.

In 2026, the Missouri Court of Appeals left the verdict in place, and Abbott indicated that it intended to seek further review from the Missouri Supreme Court. (Reuters)

A large jury verdict should not be treated as an “average NEC settlement.”

Verdicts can be appealed, reduced, reversed, or resolved differently after trial.

Has the NEC baby formula litigation settled?

There is no single global settlement resolving MDL 3026 as of August 18, 2026.

The JPML still reported 825 pending federal cases as of August 3, and a federal bellwether jury trial is underway in Chicago. (JPML)

Individual cases may settle, be dismissed, reach verdicts, or resolve on appeal.

That does not create a universal settlement for all families.

How much is an NEC baby formula lawsuit worth?

There is no established universal payout.

The value of an individual claim can depend on factors such as:

• Severity of NEC
• Whether surgery was required
• Amount of intestine removed
• Short bowel syndrome
• Long-term nutritional support
• Developmental complications
• Medical expenses
• Future care
• Wrongful death
• Strength of feeding-history evidence
• Strength of causation evidence
• Applicable state law
• Outcome of litigation or settlement

Large jury verdicts from individual cases should not be divided by the number of pending claims to estimate an individual settlement.

That would not reflect how personal-injury compensation works.

Who may be affected by the NEC litigation?

Potential claims generally involve infants who:

• Were born prematurely or at very low birth weight.
• Received a cow’s-milk-based premature infant formula or fortifier.
• Later developed NEC.
• Experienced serious injury, surgery, long-term complications, or death.
• Have medical records documenting feeding history and NEC.
• Meet applicable filing deadlines and legal requirements.

Formula exposure alone does not establish a claim.

Likewise, an NEC diagnosis alone does not establish that formula caused the disease.

What evidence may matter in an NEC case?

Because these claims involve medically fragile newborns receiving complex NICU care, the medical record can be especially important.

Potential evidence includes:

Feeding records

• NICU feeding orders
• Nursing records
• Nutrition records
• Formula administration records
• Human milk intake
• Donor milk records
• Fortifier records
• Product name and formulation

Medical records

• Gestational age
• Birth weight
• NEC diagnosis
• Imaging
• Laboratory testing
• Surgical records
• Pathology
• Antibiotic treatment
• Hospital course
• Discharge records

Long-term records

• Short bowel syndrome treatment
• Feeding-tube records
• Developmental treatment
• Nutritional care
• Additional surgeries
• Rehabilitation
• Long-term medical expenses

In wrongful-death claims, records documenting the infant’s complete hospitalization and cause of death may also be important.

Do parents need receipts for formula used in the NICU?

Usually, the most important product-use evidence may come from hospital and NICU records, not retail receipts.

Many products at issue were administered in hospital settings.

Medical and nutritional records may identify:

• Manufacturer
• Product
• Feeding dates
• Amounts
• Fortifiers
• Other nutritional sources

That can make hospital records particularly valuable in establishing the infant’s feeding history.

Is NEC always caused by formula?

No.

NEC can occur in premature infants who receive human milk as well as those who receive formula.

The NIH Working Group specifically states that human milk substantially reduces NEC risk but does not eliminate it. (NICHD)

Prematurity itself is the primary known risk factor.

NEC is considered a multifactorial disease, meaning several biological and environmental factors may contribute to its development.

Should parents avoid infant formula because of these lawsuits?

Parents and caregivers should not make feeding decisions for a premature infant based on litigation advertising or a glossary article.

FDA, CDC, and NIH state that while human milk is preferred and protective against NEC, all infants should be fed as soon as medically feasible using an appropriate nutritious food source that is available. (U.S. Food and Drug Administration)

Premature infants have specialized nutritional needs.

Feeding decisions in a NICU should be made with neonatologists and other qualified healthcare professionals who understand the infant’s individual medical needs.

Is there a deadline to file an NEC baby formula lawsuit?

Yes.

Product-liability, personal-injury, and wrongful-death claims are subject to statutes of limitation.

Deadlines can depend on:

• State law
• Child’s age
• Date of injury
• Date of death
• When parents discovered or reasonably could have discovered the alleged claim
• Which defendants are involved
• Other case-specific circumstances

Some states apply special rules to claims involving minors.

Parents should not assume that the child’s age automatically extends every potential claim indefinitely.

Common misconceptions

Myth: The federal government has determined that cow’s-milk-based premature infant formula causes NEC.

Reality: FDA, CDC, and NIH have expressly stated that there is no conclusive evidence that preterm infant formula causes NEC. The evidence does strongly show that human milk is protective against NEC. Prematurity remains the primary risk factor, and researchers continue studying why feeding type affects risk. (U.S. Food and Drug Administration)

Why this matters

NEC baby formula litigation involves an unusually difficult intersection of law, medicine, nutrition, and parental decision-making.

The easiest story would be:

“Formula causes NEC.”

But the scientific evidence does not support presenting the issue that simply.

A more accurate picture is:

• NEC is a serious disease primarily affecting premature infants.
• Prematurity itself is the primary risk factor.
• Human milk has a well-supported protective effect.
• Formula-fed premature infants have experienced higher NEC rates in multiple studies.
• Scientists do not yet have conclusive evidence that formula itself independently causes NEC.
• Families are asking courts to determine whether manufacturers had legal duties to warn about the evidence that did exist.
• Courts and juries have reached different results in individual cases.

That complexity is exactly why families deserve an explanation grounded in current science and court records rather than litigation advertising.
