NEC Baby Formula Lawsuit 2026: MDL 3026, Similac & Enfamil Claims
NEC baby formula lawsuit claims allege that certain cow’s-milk-based preterm infant formulas and fortifiers—including products sold under Similac and Enfamil brands—contributed to necrotizing enterocolitis in premature infants and that manufacturers failed to provide adequate warnings. Federal cases are centralized in MDL 3026 in the Northern District of Illinois before Judge Rebecca R. Pallmeyer, and Abbott and Mead Johnson dispute liability and individualized causation.

What Is the NEC Baby Formula Lawsuit About?
MDL 3026 coordinates federal product-liability cases alleging that cow’s-milk-based preterm infant nutrition products marketed principally under Similac and Enfamil brands contributed to NEC in premature infants and that manufacturers failed to adequately warn parents and healthcare providers. The defendants deny that their products are legally responsible for individual infants’ injuries.
Failure to Warn
Families allege manufacturers did not adequately communicate the claimed NEC risk associated with certain cow’s-milk-based preterm nutrition products.
Necrotizing Enterocolitis
NEC can involve intestinal inflammation, tissue necrosis, perforation, sepsis, bowel resection, long-term complications or death.
Causation Is Disputed
Federal health agencies say current evidence does not conclusively establish that preterm formula itself causes NEC, while human milk has a strong protective association.
Who May Qualify for an NEC Formula Lawsuit?
There is no single public rule that automatically determines eligibility. A claim-specific review generally considers prematurity, the exact formula or fortifier used, timing of feeds, NEC diagnosis and severity, medical history, alternative risk factors, damages and filing deadlines.
Premature Birth & NICU Feeding
- Infant born prematurely or with very low birth weight.
- NICU or hospital records documenting enteral feeding.
- Records identifying Similac, Enfamil or another relevant cow’s-milk-based preterm nutrition product.
Confirmed NEC Diagnosis
- Medical documentation of necrotizing enterocolitis.
- Imaging, surgery, pathology, operative findings or documented treatment.
- Timeline showing feeding exposure before NEC was identified.
Serious Complications
Bowel perforation, sepsis, surgery, bowel resection, short bowel syndrome, feeding support, developmental impact, prolonged hospitalization or wrongful death can materially affect damages.
Product & Legal Proof
Manufacturers, product names, hospital feeding logs, applicable state law, limitations periods, alternative causes and defendant-specific evidence can affect whether a claim may proceed.
NEC Formula MDL 3026 Status in August 2026
In re: Abbott Laboratories, et al., Preterm Infant Nutrition Products Liability Litigation, MDL No. 3026, is centralized in the Northern District of Illinois before Judge Rebecca R. Pallmeyer. JPML’s August 3, 2026 report lists 825 pending actions and 1,035 historical actions.
April 8, 2022 — MDL 3026 Centralized
JPML centralized federal cases involving allegations that cow’s-milk-based Similac and Enfamil preterm nutrition products are associated with NEC in premature infants.
May 2, 2025 — First Abbott Bellwether Summary Judgment
In the Mar bellwether case, the court granted Abbott summary judgment on the specific state-law claims presented there. That ruling did not resolve every NEC case in the MDL.
2025 — Additional Abbott Bellwether Rulings
The district court later granted summary judgment in the Diggs and Brown bellwether cases for case-specific evidentiary and state-law reasons.
May 8, 2026 — Inman Claims Against Mead Johnson Survive
The court denied Mead Johnson & Company’s motion for summary judgment in the Inman bellwether, allowing failure-to-warn and design claims to proceed beyond that stage. The court granted summary judgment to a separate Mead Johnson Nutrition Company entity on the record before it.
July 28, 2026 — Seventh Circuit Reversal and Remand
In five Pennsylvania-origin cases, the Seventh Circuit rejected the district court’s “no real intent” fraudulent-joinder theory and remanded for further proceedings. The ruling concerns federal jurisdiction, not the scientific merits of NEC causation.
August 3, 2026 — 825 Actions Pending
JPML’s monthly report lists 825 pending and 1,035 historical actions in MDL 3026.
What Does Current Research Say About Formula, Human Milk and NEC?
The strongest current federal summary does not say that preterm infant formula has been conclusively proven to cause NEC. A 2024 federal working-group report and subsequent FDA/CDC/NIH consensus emphasized two points: there is no conclusive evidence that preterm infant formula causes NEC, and there is strong evidence that human milk is protective against NEC.
The NICHD working-group report stated that available evidence supports the hypothesis that the absence of human milk—rather than formula exposure by itself—is associated with increased NEC risk. The report also noted that among premature infants, pasteurized donor milk used as a supplement from the start of feeding is associated with about a 50% reduction in NEC risk compared with preterm formula.
No Conclusive Formula-Causation Finding
FDA, CDC and NIH have said current evidence does not conclusively establish that preterm formula itself causes NEC.
Human Milk Is Protective
Multiple federal sources recognize a lower NEC risk among preterm infants receiving human milk.
4.2% vs. 9%
In an NIH-funded trial of extremely preterm infants receiving no maternal milk, NEC occurred in 4.2% of the donor-milk group versus 9% of the formula group.
What Is Necrotizing Enterocolitis?
Necrotizing enterocolitis is a serious gastrointestinal disease that primarily affects premature infants. It involves intestinal inflammation and can progress to tissue death, perforation, infection and systemic illness. NICHD notes that the cause is not well understood and that prematurity and an immature digestive system are central risk factors.
Possible Signs
Abdominal distension, feeding intolerance, vomiting, blood in stool, lethargy, temperature instability or changes in breathing can occur with NEC.
Hospital Treatment
Care may include stopping enteral feeds, gastric decompression, antibiotics, IV nutrition, respiratory support and close monitoring.
Surgery
Perforation or severely damaged bowel may require surgery, bowel resection or other procedures.
Long-Term Effects
Severe NEC can contribute to short bowel syndrome, feeding problems, growth issues, developmental impairment, future care needs or death.
Similac, Enfamil and Preterm Nutrition Products in NEC Claims
JPML describes MDL 3026 as involving allegations about cow’s-milk-based infant formula products marketed under Similac by Abbott and Enfamil by Mead Johnson. Current FDA listings show multiple premature formulas and human-milk fortifiers sold by both manufacturers. The specific product administered to an infant should be verified from hospital feeding records rather than inferred from brand name alone.
| Manufacturer / Brand | Examples in Current FDA Listings | Claim-Relevant Proof |
|---|---|---|
| Abbott / Similac | Similac Special Care premature formulas; Similac human milk fortifiers | NICU feeding administration records, hospital orders, labels, lot/product data and timing. |
| Mead Johnson / Enfamil | Enfamil Premature formulas; Enfamil human milk fortifiers | NICU feeding administration records, hospital orders, labels, lot/product data and timing. |
| Other nutrition products | The FDA lists additional preterm and specialty nutrition products from other manufacturers. | Do not assume every cow’s-milk-based or specialty formula is automatically within MDL 3026; defendant and product scope require legal review. |
