Latest NEC Infant Formula Lawsuit Updates

(Necrotizing Enterocolitis Claims, May 2026)

Our attorneys are reviewing claims from parents whose premature infants developed necrotizing enterocolitis (NEC) after being fed cow-milk-based Similac or Enfamil products in the NICU.

Claims are consolidated in MDL 3026, In re: Abbott Laboratories, et al., Preterm Infant Nutrition Products Liability Litigation, in the U.S. District Court for the Northern District of Illinois before Judge Rebecca R. Pallmeyer.

To qualify, the infant must have been born premature (typically before 37 weeks gestation, with most claims involving infants born before 33 weeks), fed Similac or Enfamil cow-milk-based formulas or fortifiers in a NICU, and diagnosed with NEC.

Fill out the form to check eligibility for a free case review.

The litigation alleges that Abbott Laboratories (Similac) and Mead Johnson (Enfamil, owned by Reckitt) marketed cow-milk-based formulas for use in premature infants without adequately warning that NEC risk is significantly higher with cow-milk formulas than with human milk.

Bellwether Track Update: The MDL has produced split bellwether outcomes. The Watson v. Abbott trial in St. Louis state court returned a $495 million verdict for the plaintiff in March 2024 (later reduced post-trial). A subsequent federal bellwether returned a defense verdict. The trial split has shaped ongoing settlement negotiations.

FDA Update: The FDA convened multiple advisory meetings on infant formula safety following the litigation. Labeling and clinical-trial standards remain under review.

"Premature infants fed cow-milk formula develop NEC at substantially higher rates than those fed human milk."

What Is Necrotizing Enterocolitis

Necrotizing enterocolitis is a devastating intestinal disease that primarily affects premature infants in Level III and Level IV NICUs. The intestinal tissue dies, the gut wall can perforate, and bacteria leak into the abdominal cavity. Without rapid surgical intervention (typically bowel resection with ileostomy or colostomy, sometimes with later ileocolic anastomosis), NEC is often fatal. Survivors frequently lose substantial portions of their small or large intestine and live with lifelong complications.

NEC affects roughly 7 percent of very low birth weight infants (under 1,500 grams) in U.S. NICUs. Mortality runs between 15 percent and 40 percent depending on Bell stage at diagnosis. Survivors who undergo bowel resection face short-bowel syndrome (also called short gut syndrome), intestinal stricture, parenteral nutrition dependence, central line complications, cholestatic liver disease, developmental delays, and frequent hospital readmissions.

The medical literature has documented for decades that NEC risk is dose-dependent on cow-milk-based feeds. The Cochrane Reviews, the American Academy of Pediatrics, and the World Health Organization all recommend exclusive human milk feeding for premature infants whenever possible. Donor human milk is recommended when the mother's own milk is unavailable.

The plaintiffs' theory: Abbott and Mead Johnson knew that cow-milk-based formulas elevated NEC risk in premature infants and continued to market and sell those products to NICUs without adequate warnings.

Why this litigation is unusual:

Plaintiffs are infants and their families, with damages including lifelong medical care
Bellwether outcomes have split (large plaintiff verdict and defense verdict in 2026 alone)
The medical evidence on cow-milk vs. human milk is decades old
Damages are catastrophic when proven (multi-million-dollar care needs over a child's lifetime)

The Science: Cow-Milk Formula vs. Human Milk

The Cochrane Database of Systematic Reviews has examined NEC and feeding type repeatedly. The findings are consistent: human milk feeding reduces NEC incidence in premature infants. Donor human milk shows similar benefits when mother's own milk is unavailable.

The Lucas and Cole 1990 Lancet Study

Hard Truth: The seminal Lucas and Cole study, published in The Lancet in 1990, found premature infants fed exclusively cow-milk formula had 6 to 10 times the NEC incidence compared to those fed exclusively human milk. The study has been replicated and refined many times since. The fundamental finding has not been overturned.

The Cochrane Review

Hard Truth: Cochrane's 2019 review on formula vs. donor breast milk for preterm infants confirmed that formula feeding increased NEC risk. The review was based on multiple randomized controlled trials. The evidence base is among the strongest in neonatal nutrition.

What the Manufacturers Knew

Hard Truth: Internal Abbott and Mead Johnson documents produced in MDL 3026 show that the companies knew about the elevated NEC risk in cow-milk formulas. Plaintiffs allege the products were marketed to NICUs and to mothers as a safe and convenient alternative without disclosing the risk that the medical literature had documented for decades.

Named Defendants and Products at Issue

Two corporate parents and a defined list of products dominate the litigation:

Defendants and Their NICU Products

The MDL names two main corporate defendants and their full product lines marketed for premature and low-birth-weight infants.

Abbott Laboratories (Similac product line)
Similac Special Care, Similac NeoSure, Similac Human Milk Fortifier, Similac Alimentum, Similac Sensitive (premature infant variants). Abbott manufactures these products in Sturgis, Michigan. The same Sturgis facility was the subject of the unrelated 2022 Cronobacter recall, which compounds public attention on Abbott's preterm-infant nutrition line.
Mead Johnson / Reckitt (Enfamil product line)
Enfamil Premature, Enfamil EnfaCare, Enfamil Human Milk Fortifier, Enfamil NeuroPro EnfaCare. Mead Johnson is owned by Reckitt Benckiser. The Enfamil preterm formulas have been marketed to NICUs for decades and appear in plaintiff fact sheets at frequencies similar to Similac.
Hospitals as additional defendants
Some plaintiffs name hospitals or NICU systems as additional defendants under negligent-failure-to-warn or informed-consent theories. Whether a hospital remains in the case depends on jurisdiction-specific defenses (charitable immunity, the learned intermediary doctrine, and similar issues). Most claims focus on the manufacturers.

Pediatric formula in retail stores
Standard infant formulas sold at retail (Similac Advance, Enfamil NeuroPro Infant) are not the focus. The litigation centers on premature-infant nutrition products administered in NICUs. If your child was a healthy term newborn fed standard formula, the MDL 3026 claims do not apply.

Bellwether Outcomes So Far

Mixed verdicts have shaped negotiations

The Watson v. Abbott trial in St. Louis Circuit Court (a parallel state-court case, not technically a federal MDL bellwether) returned a $495 million verdict for the plaintiff in March 2024. The award was reduced after post-trial motions but remained substantial. The trial demonstrated that juries can find for plaintiffs on both general causation and specific causation when the medical evidence is presented effectively.

A subsequent federal bellwether returned a defense verdict. That outcome reflected the difficulty of proving specific causation in cases where multiple risk factors (extreme prematurity, antibiotic exposure, sepsis) compete with the formula as the cause of NEC.

The split outcomes have driven both sides toward serious settlement discussions. Whether a global settlement matrix emerges depends on additional bellwether outcomes and discovery developments.

Statute of Limitations and Tolling

Time limits in pediatric cases

Most states toll the SOL during a child's minority. The clock typically begins when the child reaches age 18 or when the parents discovered the link between formula and NEC, whichever applies under state law. This means many parents whose children were diagnosed years ago still have valid claims.

Some states have shorter tolling rules. Confirm your state's specific rules through a free case review before assuming the window has closed.

Wrongful Death Track

When NEC was fatal

NEC mortality runs between 15 percent and 40 percent. When an infant dies from NEC, the wrongful death claim is governed by state law and typically has its own SOL clock starting from the date of death. See our overview of wrongful death claims.

Surviving parents may recover under both wrongful death statutes and survival actions, depending on jurisdiction. The damages calculus differs from non-fatal cases.

Who Qualifies to File an NEC Lawsuit

Eligibility centers on three things: a premature birth, NICU formula feeding, and an NEC diagnosis.

Premature birth: Born before 37 weeks gestation, with most qualifying claims involving very preterm (before 32 weeks) or extremely preterm (before 28 weeks) births
Low birth weight: Many qualifying cases involve very low birth weight (under 1,500 grams) or extremely low birth weight (under 1,000 grams)
NICU formula: Fed Abbott Similac or Mead Johnson Enfamil cow-milk-based formula or human milk fortifier during NICU stay
NEC diagnosis: Bell stage II or III NEC documented in NICU medical records, with imaging or pathology confirmation
Outcome: Surgical intervention, bowel resection, short-bowel syndrome, developmental delays, or death

Documentation That Strengthens a Claim

"NICU records and discharge summaries are the backbone of an NEC claim. Pull them early."

Records to gather:

NICU admission and discharge summaries; daily nursing notes; feeding logs showing the specific formula brand and date of introduction; abdominal radiographs and imaging reports; surgical operative notes if bowel resection was performed; pathology reports; pediatric gastroenterology and developmental follow-up records; and any photographs or NICU communications documenting the feeding choice.

Even if your records are incomplete, share what you have. The intake team can request missing records from hospitals.

Compensation Available in NEC Claims

NEC cases involve some of the highest compensable damages in any active mass tort because the victim is typically a child with lifetime needs.

Economic damages: NICU and follow-up medical costs, surgical bills, parenteral nutrition expenses, lost parental wages during prolonged hospitalization, future medical care including likely revision surgeries, life-care plan costs, special education, and assistive technology.

Non-economic damages: the child's pain and suffering, emotional distress, loss of normal childhood experiences, loss of consortium for parents.

Wrongful death damages: in fatal cases, funeral costs, loss of the parent-child relationship, and survival-action damages for the infant's pre-death pain.

Punitive damages: available where the evidence supports a finding that the manufacturers knew about the NEC risk and continued to market the products without warning. The internal documents discovered in MDL 3026 form the foundation for punitive arguments.

The Watson v. Abbott $495 million verdict reflects what juries can do when the case is presented effectively. Settlement matrices, when they emerge, will tier values by NEC severity, surgical history, ongoing medical needs, and survival vs. fatal outcome. Catastrophic-injury settlement values in NEC cases are evaluated against benchmarks from other active mass tort cases our firm represents.

Frequently Asked Questions

What does an NEC formula attorney cost?

NEC cases are handled on contingency. You pay no out-of-pocket fees. Attorney fees come from money recovered in your case. If we do not recover, you owe nothing.

Does breastfeeding history hurt my claim?

No. Many qualifying claims involve infants who received some breast milk in addition to cow-milk formula. The litigation focuses on cow-milk-based product exposure during NICU stay. Mixed feeding history does not disqualify a case as long as cow-milk formula was used and NEC was diagnosed.

How long does an NEC case take?

Mass tort cases typically run several years from filing to resolution. Settlement timelines depend on bellwether outcomes and global negotiations. Individual cases that proceed through trial can take longer. Be prepared for a multi-year process.

What if my child died from NEC?

You may have a wrongful death claim in addition to a survival action. The SOL typically runs from date of death rather than diagnosis. Damages reflect the loss of the parent-child relationship, funeral expenses, and the infant's pre-death pain and suffering.

Is there a class action settlement to join?

No. NEC cases are individual claims, not a class action. Each case is filed separately and proceeds individually within MDL 3026. Many will eventually resolve through a global settlement matrix; until then, individual filings are required.

Similac and Enfamil NEC Lawsuit: Additional Questions

Q: My child got NEC from Similac. Can I sue Abbott?: A: Yes, if your premature infant received Similac Special Care, NeoSure, Human Milk Fortifier, Alimentum, or Sensitive cow-milk-based formula in a NICU and was diagnosed with Bell stage II or III necrotizing enterocolitis, a Similac NEC lawsuit against Abbott Laboratories may be filed in MDL 3026. NICU records, feeding logs, and pathology reports anchor the case. Speak with a Similac NEC attorney to confirm eligibility.
Q: My child got NEC from Enfamil. Can I sue Mead Johnson?: A: Yes. Enfamil Premature, EnfaCare, Human Milk Fortifier, and NeuroPro EnfaCare cow-milk-based products are part of MDL 3026 alongside the Similac products. Mead Johnson is owned by Reckitt Benckiser. An Enfamil NEC lawyer evaluates the same eligibility criteria as Similac claims (premature birth, NICU formula feeding, Bell stage II or III NEC diagnosis).
Q: What is the average NEC settlement amount?: A: A global settlement matrix has not been finalized. The Watson v. Abbott $495 million state-court verdict in March 2024 (later reduced post-trial) anchors the high end of what is possible. Federal bellwether outcomes have been mixed. Settlement values turn on NEC severity (Bell stage II vs. III), surgical intervention (bowel resection, ileostomy, hysterectomy of NICU outcomes), short-bowel syndrome diagnosis, lifetime care needs, and survival vs. fatal outcome. Catastrophic cases with lifetime parenteral nutrition or significant developmental delay sit highest.
Q: My child needed an ileostomy or colostomy. Does that strengthen my claim?: A: Yes. Surgical intervention (bowel resection with creation of an ileostomy or colostomy, later takedown with ileocolic anastomosis, or in severe cases, total or near-total bowel resection) is documented evidence of Bell stage III NEC. The surgical course is among the strongest evidence in any NEC case and typically places the case in a higher tier of any settlement matrix that emerges. Operative reports and pathology of resected bowel should be preserved.
Q: How do I find an NEC formula attorney near me?: A: Most NEC formula cases are filed directly in MDL 3026 in the Northern District of Illinois under the court's direct-filing order. Local attorneys are not required. You want an NEC formula law firm with MDL experience, the resources to fund medical-record collection and life-care planning, and a documented relationship with the plaintiffs' steering committee. The case review is free and runs by phone.
Q: Was donor breast milk available when my child was in the NICU?: A: HMBANA-accredited donor human milk banks have served NICUs since the 1980s. Whether donor milk was offered, declined, or unavailable at your hospital is a fact-development point in the case. Either way, the litigation theory targets the manufacturers' failure to warn about the elevated NEC risk of cow-milk products, not the hospital's individual feeding decisions (with limited exceptions for specific informed-consent claims).

How to File an NEC Formula Lawsuit

The intake process is straightforward and costs nothing to start.

Step 1: Free case review. Share your child's birth history, NICU stay, NEC diagnosis, and current condition.
Step 2: Records request. We request NICU records, feeding logs, surgical notes, and follow-up care records from the hospitals.
Step 3: Eligibility confirmation. The intake team confirms whether your case fits the MDL 3026 criteria and your state's filing window.
Step 4: Direct filing. Most cases are filed in the N.D. Ill. directly under the MDL's direct-filing order, preserving home-state-law advantages.
Step 5: Plaintiff fact sheet and discovery. Detailed fact sheet documents NICU stay and current condition. Discovery proceeds at the MDL level.
Step 6: Resolution. Through bellwether-driven settlement matrix, individual settlement, or remand for trial.

Defenses and Hurdles in NEC Cases

The defendants will challenge two things hardest. First, specific causation. NEC has multiple risk factors (prematurity itself, sepsis, antibiotic exposure, asphyxia). The defense will argue that the formula was not the cause of any individual infant's NEC.

Second, learned-intermediary doctrine. Defendants argue that warnings to NICU physicians, not directly to parents, are sufficient. The strength of this defense depends on jurisdiction and on what the manufacturers actually told NICU staff.

Plaintiffs counter with the strength of the cohort and trial evidence (Lucas/Cole, Cochrane, randomized controlled trials), with internal corporate documents on what the manufacturers knew, and with expert testimony from neonatologists.

The Watson verdict shows that juries can be persuaded. The defense bellwether shows that the case must be presented carefully.

The medical-device parallel for the learned-intermediary fight is the Paragard IUD breakage litigation, where the same doctrine is being tested. For another active mass tort centered on harm to minors and the duty to warn parents directly, see the social media adolescent mental health litigation.

Time Pressure: Why Sooner Is Better Than Later

Most states toll the SOL during a child's minority, but not all do. Some states have caps on the tolling period. Records are easier to retrieve closer to the NICU stay. Memory of feeding decisions fades. Witnesses move and hospitals change records systems.

If your premature child was fed cow-milk formula in a NICU and developed NEC, the case review is free, confidential, and time-protective. Waiting can cost the case.
