The nec lawsuit has shaped product liability law in 2024 and 2025. Parents sued formula makers over necrotizing enterocolitis in premature infants. The litigation spans federal and state courts. Juries have issued massive verdicts. Federal bellwethers have faced dismissals. Settlement talks depend on what happens next.
Courts are weighing science, warnings, and the concept of causation. Judges are testing experts under strict standards. Outcomes will influence many families and two major companies. This guide explains every crucial point in clear language.
What “NEC” Means in this Litigation
NEC means necrotizing enterocolitis. The disease strikes many preterm and very low birth weight infants. Doctors fear it because it can destroy bowel tissue. The condition may require surgery. Some infants die despite care. Studies cited in filings describe severe risks for formula-fed preemies.
Parents allege that milk formulas increase the risk of NEC in preemies. Suits target formulas sold under the Similac and Enfamil brands. Plaintiffs say companies failed to warn hospitals and families. Defendants deny those claims and challenge causation.
Who the Defendants Are
Two corporate groups face the core claims. Abbott Laboratories sells Similac. Mead Johnson, a Reckitt business, sells Enfamil. Both companies contest liability. They argue their products meet standards. They also say that NEC arises from a complex set of factors.
Where the Federal Cases Sit Today
Hundreds of cases are consolidated in MDL 3026. The court sits in the Northern District of Illinois. Chief Judge Rebecca R. Pallmeyer oversees pretrial steps. The docket features bellwether selections and Daubert motions. Plaintiffs and defendants fight expert battles there.
Plaintiffs also press claims in state courts. Missouri and Illinois trials set the early tone. Those results still shape strategy. Federal rulings now add new pressure points.
Headline Results So Far
Two state juries reached blockbuster outcomes in 2024. An Illinois jury awarded 60 million dollars in March 2024. A St. Louis jury awarded 495 million in July 2024. Those verdicts fueled filings nationwide.
A later Missouri defense verdict was overturned. A judge vacated it and ordered a new trial in March 2025. The court cited defense misconduct in that case. That ruling restored momentum for plaintiffs in state venues.
Federal bellwethers have gone differently. Judge Pallmeyer granted summary judgment to Abbott in Mar v. Abbott on May 2, 2025. The case never reached a jury. The court emphasized the narrow reach of that ruling.
A second bellwether fell on July 29, 2025. The court excluded a key causation expert and dismissed the Diggs case. Analysts flagged serious challenges for MDL plaintiffs.
What Those Federal Rulings Mean
Summary judgment blocks juries when proof falls short. The first ruling focused on warnings evidence in a specific case. The second ruling turned on expert causation for that infant. Plaintiffs insist those facts are narrow. The judge also noted limits on the decisions. Yet defense wins in bellwethers raise settlement hurdles.
State juries may still value evidence differently. Plaintiffs rely on those earlier verdicts to keep pressure high. The retrial order bolsters that argument. Ongoing appeals and new trials will set the stage for the next phase.
How Many Cases Remain
More than 700 federal cases remain active. One tracker listed 759 pending as of August 2025. New filings continue in state courts as well. The numbers shift as cases resolve or move.
The court has also refined case management. A July 2025 amended order required MDL census forms from new Abbott plaintiffs. That step helps organize claims and medical proof. Scheduling orders continue to evolve.
The Science Plaintiffs Rely On
Plaintiffs present epidemiology and clinical studies. Many focus on preterm infants fed milk formulas. Several studies report higher NEC rates versus human milk. Hospital practice trends reflect these concerns. Plaintiffs argue companies knew the risk and failed to warn.
Defendants counter with other science. They cite multifactorial causation for NEC. They stress infection, gestational age, and comorbidities. Defense experts argue that human milk availability drives outcomes. Both sides press complex biology and statistics. The judge must screen that science before juries hear it.
The Law That Controls Expert Testimony
Federal courts follow Daubert standards. Judges act as gatekeepers for expert opinions. Experts must use reliable methods that are tied to the case facts. The court excluded a plaintiff expert in Diggs on those grounds. That led to summary judgment.
General causation and specific causation differ. General causation asks if a product can cause an injury. Specific causation asks if it did so in this child. Judges may admit one and exclude the other. That split can decide a case.
The Claims at Issue
Parents bring failure-to-warn claims. Some plead design defect and negligence. Others raise breach of warranty theories. Defense teams assert federal preemption and causation gaps. Courts handle those defense cases on a case-by-case basis. Preemption has not ended the MDL. Causation fights remain central.
The State Court Playbook
State trials set early expectations. Plaintiffs point to the 60 million and 495 million dollar verdicts. Those juries credited warnings and risk evidence. Hospitals and experts testified about feeding practices. Those results show how juries might react outside the MDL.
The vacated defense verdict also matters. That order accused defense counsel of misconduct. A new jury will hear the case again. Litigants study that opinion for future boundaries.
Where Trials May Go Next
Calendars continue to shift after the July dismissal. Several trackers previously listed an August 2025 trial window. The Diggs dismissal removed one trial from that schedule. Other trials appear set for late 2025. Parties now reframe strategies around those dates.
State venues may move faster. Plaintiffs often prefer those courts after federal setbacks. Defense teams may remove or consolidate when possible. Both sides watch each ruling for leverage.
What Settlement Could Look Like
Public sources project broad ranges. Some firms suggest six-figure averages for moderate injuries. Severe surgical injuries could reach seven figures. Recent verdicts show higher upside in extreme cases. Bellwether outcomes will drive any grid or tier plan. No global deal exists yet.
Plaintiffs need jury momentum to increase their value. Defendants now point to two federal dismissals. Those rulings put lower pressure on settling quickly. The retrial order offsets that effect in part. Ongoing trials will decide which force prevails.
What Families Should Document
Medical records matter most. NICU feeding logs can prove product exposure. Growth charts, imaging, and surgical notes also provide valuable assistance. Families should preserve packaging and receipts when available. Lawyers use those records to prove elements and damages.
Statutes of limitation still apply. Time limits vary across states. Tolling may apply in some situations. Only a licensed attorney can calculate the deadline. Parents should consult counsel fast.
Hospital Practice and Policy Shifts
Hospitals now examine feeding protocols for preemies. Many units emphasize the use of human milk and donor milk. Human-milk fortifiers from human sources are expanding. Professional guidance continues to evolve. Litigation has amplified those trends.
Manufacturers stress that their products meet regulations. They also note the absence of NEC-specific recalls. Regulators have acted on separate contamination issues. Those events are distinct from the NEC theory. Public confusion often blends them. Courts separate those threads.
Corporate Statements and Investor Angles
Companies issue updates after major rulings. Reckitt confirmed the Missouri retrial order in March 2025. The statement emphasized ongoing defenses. Investors monitor these releases for risk signals. Legal spend and reserves may change over time.
Analysts now model divergent scenarios. Federal dismissals reduce near-term exposure. State retrials and verdicts still pose tail risk. The final mix will depend on the upcoming trials. Markets react to each ruling.
How Plaintiffs Frame Causation
Plaintiffs connect cow’s milk proteins to gut injury pathways. They cite inflammatory cascades in fragile intestines. Medical literature supports associations in preterm infants. They argue that warnings should have directed different feeding choices. Jurors heard that framing in 2024 trials.
How Defendants Frame Causation
Defendants challenge both general and specific causation. They argue that NEC arises from infection and prematurity. They cite studies downplaying direct causation from the formula alone. Defense experts stress confounders and selection bias. Courts must decide which experts jurors hear. Recent MDL rulings favored those defense positions.
What the Gatekeeping Rulings Teach
Expert opinions must fit each infant’s facts. The court scrutinized gestational age and weight. Causation opinions must match those details reliably. Any mismatch risks exclusion. That lesson drove the Diggs dismissal. Litigants now tailor reports more narrowly.
Case Management After the Dismissals
The MDL continues despite those losses. The court is organizing new bellwethers and schedules. A recent census order tightened reporting for new cases. That step promotes data completeness. It also signals long-term administration.
Practical Guidance for Affected Families
Parents should ask hospitals for complete NICU records. Pharmacy logs and nurse notes help track exposure. Discharge summaries and follow-ups are also important. Families should keep journals about feeding and symptoms. Those details support damage proof.
Doctors should lead medical decisions. Lawsuits cannot substitute for care. Parents should seek a second opinion when they are unsure. Support groups and care teams can help with stress. Legal counsel can manage case steps in parallel.
Practical Guidance for Health Systems
Hospitals can audit feeding protocols for preemies. Multidisciplinary teams should review outcomes and NEC rates. Documentation should improve across NICUs. Family education materials should clarify risks and alternatives. Compliance teams should monitor labeling changes and advisories.
What Lawyers on Both Sides Should Watch
Appellate activity may reshape expert rulings. New epidemiology could alter general causation views. Additional state verdicts could swing bargaining power. MDL scheduling orders will set the pace. Parties should track census compliance and discovery.

Detailed Timeline
March 2024: An Illinois jury awarded 60 million dollars against Mead Johnson. The case involved an infant’s death after NEC. The verdict energized filings nationwide.
July 2024: A Missouri jury returned 495 million dollars against Abbott. The award included punitive damages. The case highlighted warnings and NICU evidence.
October 2024: Defendants won a Missouri trial. That verdict later fell. The judge ordered a retrial after finding that misconduct had occurred. Plaintiffs regained momentum in that venue.
May 2, 2025: Judge Pallmeyer granted summary judgment in Mar. The first federal bellwether ended before trial. The court narrowed its holding to that record.
July 29, 2025: The court excluded a plaintiff expert in Diggs. The second bellwether was dismissed. Analysts warned of MDL headwinds.
August–November 2025: Additional trial settings remain. Schedules shifted after Diggs. Late-2025 dates remain important. Parties prepare for renewed Daubert battles.
Reading the Mixed Results
State juries have favored plaintiffs so far. Those verdicts demonstrate a strong sympathy when the facts align. Federal screens have favored defendants recently. Two bellwethers failed before juries heard evidence. That split creates uncertainty for talks.
Plaintiffs will emphasize real-world NICU practice. Defense teams will emphasize method flaws and confounders. Each side has wins to cite. Future verdicts will pull values up or down.
Damages and Valuation Factors
Severity drives value in these cases. Surgical resections increase damage sharply. Long-term nutrition support increases costs. Fatal cases carry the highest exposure. Jurors also weigh warning evidence and corporate conduct. Recent state awards show the range.
Economic experts model lifetime care needs. Non-economic damages address pain and loss. Punitive damages require additional proof. Counsel on both sides tailor those models to the child.
Risk Signals for the Parties
Defendants gained leverage from the federal dismissals. Those opinions highlight causation hurdles. Plaintiffs gained leverage from state verdicts and the retrial order. Those events increase tail risk for defendants. Negotiations reflect both forces.
Investors monitor each order and verdict. Corporate statements frame expectations. The Reckitt release acknowledged the retrial ruling. That message balanced legal risk and business continuity.
What to Watch in Late 2025
Watch new Daubert rulings on expert methods and how judges handle infant-specific variables. Watch whether state juries repeat 2024 patterns. Appeals may also reshape earlier results. A significant plaintiff verdict could reignite settlement momentum.
Administrative orders will continue to refine the MDL. Census and profile forms will sharpen data. Discovery rulings will affect trial readiness. Both sides need clean proof chains.
Practical Checklist for Affected Parents
Collect hospital records and NICU feeding logs—secure product packaging when possible. Keep a diary of symptoms and treatments. Ask doctors to explain the staging and outcomes of NEC. Seek legal advice on deadlines and venue choices.
Families should separate medical care from litigation choices. Treating teams should guide medical decisions. Legal teams should handle filings and evidence. Support networks can help cope with stress.
Practical Checklist for Employers and Insurers
Hospitals should update neonatal feeding policies. Risk teams should document protocol changes. Insurers should model verdict-driven scenarios. Claims teams should track bellwether outcomes. Stakeholders should plan for a long timeline.
Ethical and Public Health Considerations
Premature infants face fragile beginnings. Feeding decisions must strike a balance between growth and risk. Donor milk access remains uneven across systems. Policy makers continue to examine coverage and supply. Litigation highlights those gaps in real time.
Editorial Take: What This Means
These cases test the warning duties in complex medical situations. Courts must weigh evolving science and product labels. Early state verdicts suggested high exposure. Two federal dismissals now complicate that view. The path forward remains uncertain.
Future juries will likely decide the signal question. Did these products materially increase the risk of NEC in specific infants? Answers will turn on medical facts and expert fit. The next trials will provide further insight.
Conclusion
The nec lawsuit continues to evolve quickly. State courts produced two huge plaintiff verdicts in 2024. A Missouri defense win later vanished after a retrial order. Federal bellwethers then shifted momentum toward the defense in 2025. Two cases ended before juries under expert and warning rulings. More than 700 suits still sit in the MDL. New state trials will shape leverage again. Families should secure their records and consult with counsel. Hospitals should tighten protocols and documentation. Everyone should watch late-2025 rulings and verdicts. The NEC lawsuit remains a high-stakes fight that turns on science, warnings, and precise proof.
