Most parents of a premature baby remember the sounds before they remember anything else: the soft alarm of a monitor, the rhythm of a ventilator, a nurse reading numbers aloud in the dark. Somewhere in those first days, a feeding plan was written into a chart, and a bottle or syringe of preterm formula came from the hospital’s own supply. If your baby later developed necrotizing enterocolitis, you may have spent a long time turning that memory over. So let us say this plainly. Following the feeding plan your NICU put in place was not a failure of parenting. It was trust placed where trust is supposed to go.

This article explains what necrotizing enterocolitis is, what the research does and does not support, where the lawsuits against formula manufacturers actually stand, and which records tend to matter. It will not tell you what your family’s situation is worth, because no honest article could.

What Necrotizing Enterocolitis Is

Necrotizing enterocolitis, usually shortened to NEC, is a serious condition in which the tissue lining a baby’s intestine becomes inflamed and can begin to die, sometimes within hours, and it is one of the most common surgical emergencies in newborn intensive care. It occurs overwhelmingly in babies born too early, with published research placing incidence at roughly 5 to 10 percent of very low birth weight infants (under 1,500 grams), higher among those under 1,000 grams. Overall mortality among infants with confirmed NEC runs around 23.5 percent, rising to roughly 34.5 percent for those requiring surgery and above 50 percent for the smallest infants who need surgery. Federal health agencies have noted that one baby dies every day in the United States from NEC; CDC data recorded 356 infant deaths attributed to it in 2022.

Children who survive NEC, particularly where a portion of intestine was removed, may face short bowel syndrome, long-term intravenous nutrition, slow growth, or developmental delay, though outcomes vary enormously and many children go on to do well.

What the Research Shows, and What It Does Not

This is the part most pages on this subject get wrong. Human milk appears to protect against NEC, and that conclusion is not seriously in dispute. In October 2024, the FDA, CDC, and NIH issued a joint consensus statement finding strong evidence that human milk is protective, with mother’s own milk preferred and pasteurized donor milk the next alternative.

Whether cow’s milk-based preterm formula itself causes NEC is a different, unsettled question. The same federal statement said there is no conclusive evidence that preterm formula causes NEC, and that available evidence supports the hypothesis that it is the absence of human milk, rather than exposure to formula, that is associated with increased risk. A Congressional Research Service review of the litigation reached the same summary. This distinction carries enormous weight: if the mechanism is the absence of human milk, a manufacturer can argue its product was part of the standard of care when human milk was unavailable; if the mechanism is something about the formula itself, a failure-to-warn claim becomes considerably stronger. Nearly every contested ruling in this litigation traces back to that fault line, and both the federal statement and independent reviews have called for further research into the remaining gaps.

What the Lawsuits Allege

The two principal defendants are Abbott Laboratories, maker of the Similac preterm line, and Mead Johnson & Company, LLC, maker of the Enfamil preterm line and a Reckitt Benckiser subsidiary. Families have generally advanced three theories: failure to warn of a known or knowable risk, design and formulation defects, and ordinary negligence. Both companies deny these allegations and have appealed adverse verdicts. Our article on chemical hair relaxer litigation [LINK TBD] covers how mass tort claims work more generally, in a different context.

Where the Litigation Stands

Federal cases are consolidated as Multidistrict Litigation 3026, In re Abbott Laboratories, et al., Preterm Infant Nutrition Products Liability Litigation, before Chief Judge Rebecca R. Pallmeyer in the Northern District of Illinois, with roughly 800 cases pending there and more in state courts. Consolidation coordinates pretrial work; it does not merge the claims, and each family’s case keeps its own facts.

Case	Court	Outcome	Where It Stands
Watson v. Mead Johnson	St. Clair County, IL	$60 million for plaintiff, March 2024	Reversed and remanded June 12, 2026; new trial available
Gill v. Abbott	St. Louis, MO	$495 million for plaintiff, July 2024 ($95M compensatory, $400M punitive)	Affirmed on appeal May 2026
St. Louis trial, Oct. 2024	St. Louis, MO	Defense verdict	Vacated; new trial ordered for errors and misconduct, on appeal
Cook County multi-family trial	Cook County, IL	$70 million for four families against Abbott, April 2026 ($53M compensatory, $17M punitive)	Abbott has indicated it will appeal
Collins v. Mead Johnson	St. Louis, MO	Defense verdict, July 2026	Jury reportedly found against plaintiff on specific causation
Federal bellwethers 1–3	MDL 3026	Resolved for the defense on summary judgment, 2025	One ruling argued on appeal before the Seventh Circuit
Inman v. Mead Johnson	MDL 3026	First federal case cleared for a jury	Trial date has shifted repeatedly; confirm current status before publication
Kelton v. Abbott	MDL 3026	Second federal bellwether	Trial scheduled for August 2026

State court juries have returned large verdicts while federal plaintiffs spent 2025 unable to reach a jury at all, since the court excluded their causation experts before trial in the first three bellwether cases. That changed when Judge Pallmeyer denied Mead Johnson’s summary judgment motion in Inman, clearing the first case where plaintiffs’ epidemiology testimony survived pretrial challenge. Outcomes have genuinely gone both ways: in July 2026, a St. Louis jury returned a defense verdict for Mead Johnson, reportedly finding against the plaintiff on whether the product caused that particular child’s illness. Any page presenting this litigation as a straight line of plaintiff wins is not describing it accurately, and trial dates have been reset more than once.

Update as of late August 2026 – Abbott has announced agreements to resolve the Gill case and claims involving roughly 2,000 additional infants, for an aggregate of approximately $670 million. This is a private settlement reached with three plaintiff firms rather than a court-administered global settlement program, so it does not resolve the litigation as a whole, and Mead Johnson is not a party to it. It should be confirmed and reflected before this article is published, since it materially changes the picture for any family evaluating an Abbott-related claim.

The Warning Question Parents Should Understand

In Watson v. Mead Johnson, the Illinois Fifth District Appellate Court reversed the $60 million verdict in June 2026 and held that the Learned Intermediary Doctrine applies to cow’s milk-based preterm formula administered in a hospital under physician orders – reportedly the first appellate decision anywhere to reach that conclusion for infant formula. The doctrine treats a manufacturer’s duty to warn as running to the treating clinician rather than directly to the parent, since the clinician has the training and full clinical picture. The court reasoned that a preterm formula selected by neonatologists after weighing a specific infant’s gestational age and condition functions much like a prescription product, even though it is not regulated as one, and sent the case back for a new trial.

This does not mean these claims are barred, and it does not automatically apply outside Illinois, since each state decides the doctrine’s reach for itself. What it does is reframe the question: rather than asking whether a parent was warned, the inquiry becomes whether the manufacturer gave the NICU’s clinicians warnings adequate to the risk, and whether a proper warning could have changed the feeding decision made for that baby. That shifts attention toward the hospital’s own documents, which is why the records below carry so much weight.

Who May Be Able to Bring a Claim, and What Records Matter

No checklist decides a case, but the factors that tend to matter are reasonably consistent: birth before 37 weeks, low birth weight often under 1,500 grams, feeding with a cow’s milk-based preterm formula or human milk fortifier during a hospital admission, a documented NEC diagnosis or related diagnosis, and records sufficient to identify which product was given. Eligibility ultimately turns on the records and the law of the state where a claim would be brought.

• Complete NICU admission and discharge records
• Feeding orders and nursing feeding logs, usually where a specific product is named
• Birth records confirming gestational age and birth weight
• Abdominal imaging, operative reports, and pathology reports if surgery was performed
• Consultation notes from neonatology, surgery, and gastroenterology
• Lactation records, including documentation about donor human milk availability

Hospitals are generally required to provide records on request, and feeding logs are sometimes stored separately from the main chart, so it helps to ask for them by name. Gaps are common in these files, particularly in older records, and a missing document is not by itself the end of an inquiry.

Damages and Deadlines

What a family may recover depends on the state and the facts, but generally falls into three categories: economic damages, including past and future medical care and lost earnings; non-economic damages, including a child’s pain and suffering or, where an infant has died, a family’s grief and loss of companionship; and, in some jurisdictions, punitive damages, which made up the larger share of both the Missouri and Cook County awards described above.

Filing deadlines are set state by state and differ in ways that surprise people. Many states pause or extend a child’s deadline until they reach adulthood, which is why some families learn years later that a claim may still be available. Deadlines in cases involving a child’s death are typically shorter and often not extended the same way, making those situations the most time-sensitive. Because the analysis depends on the state and the specific claim, it is worth having someone check rather than assuming in either direction.

A Note About Your Child’s Care Right Now

Nothing here is a reason to change a feeding plan, decline a recommended formula, or delay nutrition for a premature baby. Federal agencies have been explicit that preterm formulas are part of the standard of care when human milk is unavailable or insufficient, and every infant should be fed as soon as medically feasible. Feeding decisions belong with your baby’s clinicians; a legal question about the past is a separate matter from a clinical decision being made today.

Frequently Asked Questions

Does this mean the formula caused my baby’s NEC? – No article can answer that. Whether a specific product caused a specific child’s illness is decided on that child’s medical records, and it is precisely the question juries have split on.

The NICU chose the formula, not me. Does that hurt my case? – Generally no. After the Illinois ruling, clinician decision-making sits closer to the center of these claims. The question is what the manufacturer told those clinicians, not what a parent knew.

My child survived and is doing well. Is there still a claim? – Possibly. Some of the largest awards in this litigation involved children who survived NEC and live with lasting effects. Severity affects a case; survival does not end it.

How long do these cases usually take? – Longer than families want. There is no announced global settlement program covering the full litigation, and any firm offering a firm timeline is offering a guess.
