On July 2, 2026, a jury in St. Louis returned a verdict in favor of Mead Johnson — the maker of Enfamil — in a necrotizing enterocolitis (NEC) baby formula trial. It was a complete defense verdict, meaning the jury did not hold the company liable. For families following this litigation, and especially for families with a case of their own, a headline like that can be frightening. If a jury sided with the formula maker, does that mean the science has fallen apart? Does it mean other families no longer have a claim?
The short answer is no — but the reasons why are worth understanding, because they go to the heart of how every one of these cases is actually decided. The St. Louis jury did not rule that cow’s-milk formula is safe. According to the jury foreperson, the panel decided the case on something called specific causation. That single phrase explains both what happened in that courtroom and why a loss in one family’s trial says almost nothing about the next family’s case. This article breaks down what a defense verdict is, what general and specific causation mean, and why an NEC case rises or falls on one child’s medical records.
The one-sentence version. Every NEC formula case has to answer two separate questions — can cow’s-milk formula cause NEC (general causation), and did it cause this baby’s NEC (specific causation) — and the July 2 St. Louis defense verdict turned on the second question, for one child, not on whether the formula is dangerous.
What happened in St. Louis on July 2, 2026
The case was brought on behalf of a child identified in court records as K.H., who was born at 25 weeks and 3 days of gestation in 2021 — an extremely premature birth. The family alleged that the baby developed NEC, required surgery, and suffered lasting injuries after being fed Enfamil Premature 24, a cow’s-milk-based product, in the neonatal intensive care unit. After trial in the Circuit Court of the City of St. Louis, the jury returned a verdict for Mead Johnson.
What makes the verdict instructive is the reason behind it. In a post-verdict account, the jury’s foreperson said the panel found against the plaintiff on specific causation — the primary defense the company had put forward at trial. In plain terms, the jury was not persuaded that this particular baby’s NEC was caused by the formula, as opposed to some other cause. That is a different conclusion than deciding that formula can never cause NEC. Understanding the difference is the whole point of this post.
The two questions every NEC case has to answer
In a product-injury case like this, a plaintiff generally has to prove causation on two levels, and courts treat them as separate hurdles. General causation asks whether the product is capable of causing the injury at all. Specific causation asks whether the product in fact caused this individual plaintiff’s injury. A family can satisfy the first and still lose on the second — which is exactly what the St. Louis foreperson described.
General causation: can cow’s-milk formula cause NEC?
General causation is the population-level question: does the body of medical and scientific evidence show that cow’s-milk-based formula can cause necrotizing enterocolitis in premature infants? This is the terrain of neonatology research — the studies and reviews finding that preterm babies fed cow’s-milk formula develop NEC at higher rates than those fed human milk, and the American Academy of Pediatrics’ recommendation of human milk for preterm infants in part to reduce NEC risk. We cover that evidence in depth in the science linking cow’s-milk formula to NEC.
In federal court, general causation has been the gate that plaintiffs first had to clear. Under the Daubert standard, which governs expert testimony in federal cases, the judge screens whether an expert’s causation opinion is reliable enough to reach a jury. In the federal NEC MDL (multidistrict litigation) before Judge Rebecca Pallmeyer in the Northern District of Illinois, that gate proved decisive early on: Abbott, the maker of Similac, won its first three federal bellwether trials on summary judgment in 2025 after the court excluded the plaintiffs’ general-causation experts. More recently, the court allowed an epidemiologist to testify for the plaintiff in the first Mead Johnson federal bellwether, Inman v. Mead Johnson, which went before a jury beginning in early July 2026 — the first federal NEC case in which a plaintiff’s causation expert survived Daubert and testified. That federal trial is a separate proceeding from the St. Louis state-court case and was still underway as of this writing.
Specific causation: did the formula cause this baby’s NEC?
Specific causation is the individual question, and it is where a case like the St. Louis trial is won or lost. Even accepting that cow’s-milk formula can cause NEC, the defense will argue that a particular baby’s injury came from something else. In an extremely premature infant, there are competing explanations a defense will raise: prematurity itself, spontaneous intestinal perforation (SIP) rather than NEC, infection or sepsis, or other factors present in a fragile newborn’s course. Specific causation is the jury’s judgment about which explanation the evidence best supports for that one child.
Because it is individual, specific causation lives entirely in the record: the baby’s gestational age, exactly what was fed and when, the abdominal X-rays, the operative note, the surgical pathology, and the medication history. That is why two cases with similar-sounding facts can end differently — the documents are different.
General vs. specific causation at a glance
| Question | General Causation | Specific Causation |
|---|---|---|
| What it asks | Can cow’s-milk formula cause NEC at all? | Did the formula cause this baby’s NEC? |
| Level | Population / scientific evidence | The individual child |
| Proof relies on | Epidemiology, neonatology studies, AAP guidance | That child’s records: feeding, timing, imaging, pathology |
| Common defense move | Challenge the expert’s methodology (Daubert) | Point to a competing cause (prematurity, SIP, infection) |
| If plaintiff loses here | The claim usually cannot proceed at all | That one case fails, but others are unaffected |
This describes the general structure of causation in these cases. The precise legal standard varies by jurisdiction, and only an attorney can apply it to a specific set of facts.
Why the St. Louis finding matters — and what it does not mean
A defense verdict on specific causation is a narrow event. It resolves one family’s case, on that child’s facts, in front of one jury. It is not an appellate ruling, it does not create a precedent that binds other cases, and — critically — it is not a finding that cow’s-milk formula is safe. Other juries in this litigation have reached plaintiff verdicts in earlier trials, and at least one large plaintiff verdict was later reversed on appeal and sent back for a new trial, which we explain in what a new-trial order actually means for families. Taken together, the pattern is not “the science won” or “the science lost.” It is that individual cases are going both ways, because they are supposed to be decided one at a time.
“A defense verdict on specific causation tells you the jury wasn’t convinced about that one child — it doesn’t tell you anything about the next family’s baby,” says Alex Alvarez, Managing Partner of The Alvarez Law Firm and a Board Certified Civil Trial Lawyer. “These cases don’t rise and fall on a slogan. They rise and fall on whether, for this specific infant, the records line the formula up with the injury and rule out the alternatives. Win or lose, that work is done chart by chart.”
How specific causation is actually proven
Because specific causation is a records question, the analysis is not about arguing over the diagnosis line someone typed — it is about reconstructing the individual timeline from primary documents and confronting the competing causes directly.
“When I read one of these files, I’m testing the alternative explanations, not just the formula theory,” says Herb Borroto, M.D., J.D., the firm’s Medical-Legal Expert. “What was the gestational age? What product was ordered, and when did the feeds start relative to the first signs? Did the films show pneumatosis pointing to NEC, or a focal picture that looks more like SIP? Was there a positive blood culture suggesting sepsis? Line the objective findings up against the timeline, and specific causation stops being an argument and starts being a document trail.”
That is the same records-first discipline we describe in our guides to reading a NICU progress note and to surgical NEC versus medical NEC. The building blocks are the feeding orders and the specific product used, the abdominal imaging reports, the operative and pathology notes, the medication administration record, and the gestational age and timeline.
What families should take from a defense verdict
A few practical points if a headline like the St. Louis verdict has you worried.
First, one family’s loss does not close the door on yours. Because specific causation is decided child by child, a defense verdict in one case is not a ruling about your child. The broader litigation is ongoing, with more than 800 cases still consolidated in the federal MDL and additional trials scheduled.
Second, your case turns on your child’s records, not on the last verdict. The facts that decide specific causation — gestational age, what was fed and when, the imaging, the pathology, and whether competing causes can be ruled out — live in the NICU chart. If you kept feeding logs, photos of the whiteboard, or notes from rounds, hold onto them.
Third, the deadline runs regardless of what any jury just did. The statute of limitations that governs a potential claim depends on your child’s dates and your state’s law, and those deadlines are often shorter than parents expect. A verdict in another case does not pause your clock. You can start with whether your family qualifies for an NEC lawsuit.
This is general information, not legal or medical advice. Every premature infant’s course is different, and whether a specific child’s NEC can be tied to cow’s-milk formula requires review of that child’s complete medical record by qualified professionals. Past results do not guarantee future outcomes; each case is evaluated on its own facts.
How The Alvarez Law Firm approaches causation
When a family comes to us after a scary headline, we start where the case is actually decided: the records. Our team, led by Board Certified Civil Trial Lawyer Alex Alvarez and supported by Medical-Legal Expert Herb Borroto, M.D., J.D., obtains and reviews the full NICU record — feeding orders, imaging, operative and pathology reports, and medication histories — to assess both whether the science supports the claim and whether, for this child, the formula can be tied to the injury while the alternatives are ruled out. We do this for families nationwide, at no cost.

Frequently asked questions
What does a defense verdict mean in an NEC baby formula lawsuit?
A defense verdict means the jury decided that particular case in favor of the defendant, so no liability and no damages were awarded to that plaintiff. It resolves one family’s case on its own facts. It is not a ruling that cow’s-milk formula is safe, and it does not bind other families’ cases, which are decided one at a time on their own records. In the July 2, 2026 St. Louis trial the jury foreperson reported that the panel found against the plaintiff on specific causation.
What is the difference between general causation and specific causation?
General causation asks whether a product is capable of causing a type of injury at all — here, whether cow’s-milk-based formula can cause necrotizing enterocolitis in premature infants. Specific causation asks a narrower question: whether the product actually caused this particular baby’s NEC, as opposed to some other cause such as extreme prematurity, spontaneous intestinal perforation, infection, or another factor. A plaintiff generally has to establish both. A case can clear the general-causation question and still be lost on specific causation, which is what the foreperson described in the July 2, 2026 St. Louis defense verdict.
Does the Mead Johnson defense verdict mean the NEC formula lawsuits are over?
No. A single defense verdict resolves one case. The broader litigation is ongoing: more than 800 cases remain consolidated in the federal MDL before Judge Rebecca Pallmeyer in the Northern District of Illinois, and other juries have found for plaintiffs in earlier trials. Individual cases have gone both ways, because each turns on that child’s medical records, feeding history, and competing explanations rather than on a single prior result.
If another family lost their NEC trial, can my family still have a claim?
Possibly. One family’s trial loss does not decide another family’s case. NEC formula claims are evaluated individually on the specific baby’s gestational age, what product was fed and when, the radiology, operative and pathology findings, and whether competing causes can be ruled out. Because these cases are fact-specific and filing deadlines vary by state and are often shorter than parents expect, the only way to know is to have the complete record reviewed by an attorney.
