If your premature baby developed necrotizing enterocolitis after being fed Enfamil or Similac, here is who may qualify, where MDL 3026 stands, and how to find a lawyer on your own.
Allegations Only · No Settlement Yet
This article describes ongoing product-liability litigation. The statements below are unproven allegations. Abbott Laboratories (Similac) and Mead Johnson/Reckitt (Enfamil) have not been found liable in the federal MDL, there is no certified class, and there is no settlement or claim form at this time. This page is general information, not legal or medical advice.
What Are the Enfamil and Similac NEC Lawsuits?
Families of premature or low-birth-weight babies who developed necrotizing enterocolitis (NEC) after being fed Enfamil, Similac, or other cow's-milk-based formulas and fortifiers have filed product-liability lawsuits against the manufacturers. The lawsuits allege that these cow's-milk-based products can increase the risk of NEC in premature infants and that the companies did not adequately warn parents and medical providers. These are unproven allegations, and the manufacturers deny wrongdoing.The federal cases are consolidated for pretrial purposes in a multidistrict litigation (MDL): In re: Abbott Laboratories, et al., Preterm Infant Nutrition Products Liability Litigation, MDL No. 3026, in the U.S. District Court for the Northern District of Illinois before Chief Judge Rebecca Pallmeyer.

NEC Litigation Status — July 2026
As of mid-2026, roughly 800 NEC baby formula cases were pending in MDL 3026 against Abbott (Similac) and Mead Johnson, now part of Reckitt (Enfamil).• July 2026 federal bellwether: A fourth MDL bellwether trial, Inman v. Mead Johnson, went to trial beginning July 6, 2026 before Judge Pallmeyer — reported as the first Enfamil case to clear summary judgment and the Daubert expert challenge in the federal MDL. A verdict had not been reported as of this update. Bellwether trials are test cases that help both sides gauge how juries respond; they do not decide every case, but their outcomes often shape later settlement talks.
• Earlier federal bellwethers: In 2025, the court entered judgment for the defense in the first three federal test cases, largely after excluding plaintiffs' causation experts under Daubert. Plaintiffs' attorneys continued to litigate expert and causation issues heading into the 2026 trial.
• $495M Abbott verdict — affirmed, further appeal sought: A St. Louis jury's reported $495 million verdict against Abbott (Similac) was affirmed by the Missouri Court of Appeals on May 5, 2026; the court later declined to transfer the case to the Missouri Supreme Court, and Abbott has said it will seek review there, so the verdict is not yet final.
• $60M Mead Johnson verdict — reversed on appeal: A reported $60 million verdict against Mead Johnson (Enfamil) was reversed by an Illinois appeals court on June 16, 2026 over a jury-instruction issue and sent back for further proceedings — a defense win on appeal.
• April 2026 Illinois verdict: A Cook County, Illinois jury returned about $70 million against Abbott (roughly $53 million compensatory plus $17 million punitive) for several families.
• July 2, 2026 defense verdict: A St. Louis jury returned a defense verdict for Mead Johnson in a separate NEC case. These verdicts are specific to individual cases, may be reduced, reversed, or appealed, and do not guarantee any result in other cases.
There is no global settlement and no class-wide claim form. Each NEC case proceeds individually. For background on how these proceedings are organized, see our explainers on MDLs and the Judicial Panel on Multidistrict Litigation.
What Are Enfamil and Similac?
Enfamil and Similac are two of the best-known infant formula brands in the United States. Enfamil is produced by Mead Johnson, now part of Reckitt; Similac is produced by Abbott Laboratories. Both sell cow's-milk-based formulas and human-milk fortifiers that are frequently used in hospitals, NICUs, and at home when breast milk is unavailable or needs to be supplemented.These companies have also faced separate baby-formula class actions, including the Similac baby formula false advertising settlement and the Enfamil serving size class action settlement. The NEC lawsuits are different: they focus specifically on premature babies who developed necrotizing enterocolitis after receiving certain cow's-milk-based formulas and fortifiers.
Who May Be Affected by a NEC Baby Formula Lawsuit?
Attorneys reviewing potential NEC cases generally look at a few key facts:• A confirmed diagnosis of necrotizing enterocolitis (NEC)
• Premature birth before 37 weeks or low birth weight under 5.5 pounds
• Use of cow's-milk-based formula or human-milk fortifier such as Enfamil or Similac
• Records showing these products were given before NEC developed
Families in these cases often describe a NICU stay for a premature or medically fragile baby, feeding protocols that included Enfamil or Similac formulas or fortifiers, sudden symptoms such as abdominal swelling or bloody stool, imaging showing intestinal damage, and in severe cases surgery to remove damaged intestine. Only a licensed attorney can evaluate whether a specific situation may support a claim.
What Is Necrotizing Enterocolitis (NEC)?
Necrotizing enterocolitis is a serious intestinal disease that mostly affects premature infants. It causes inflammation in the intestine and can lead to tissue death. If not treated quickly, NEC can cause perforations in the bowel, severe infection, and life-threatening complications. NEC is significantly more common in premature babies and in infants who receive formula derived from cow's milk instead of exclusive human milk. Because it can progress rapidly, early recognition and immediate medical care are critical.Warning Signs and Symptoms of NEC in Babies
Parents and caregivers are often told to watch for:• A swollen, puffy, or tender belly
• Feeding difficulties or sudden refusal to eat
• Vomiting, especially if it looks green or yellow
• Bloody stool
• Lethargy or a sudden drop in energy
• Trouble gaining weight or unexplained weight loss
• Unstable body temperature
• Changes in breathing, heart rate, or blood pressure
Any of these signs require immediate medical attention. Only a doctor can diagnose NEC and decide whether antibiotics, bowel rest, surgery, or other interventions are needed.
What Increases a Baby's Risk of NEC?
Several factors are known to raise NEC risk, especially in premature infants: premature birth before 37 weeks; low birth weight under 5.5 pounds; feeding with cow's-milk-based formula or fortifier instead of exclusive human milk; serious illness or infections in the NICU; blood transfusions in fragile newborns; and low oxygen levels around the time of birth. Feeding premature babies with mother's milk or donor human milk can significantly reduce NEC risk, which is part of why cow's-milk-based products are being examined in these lawsuits.Have Enfamil or Similac Formulas Been Recalled?
Several baby formulas have been recalled in recent years for safety reasons. In February 2022, Abbott recalled certain Similac, Alimentum, and EleCare products after reports of Cronobacter sakazakii infections linked to its Sturgis, Michigan plant. In October 2022, Abbott recalled some ready-to-feed liquid formulas over improperly sealed bottles. Those recalls focused on contamination and packaging issues rather than NEC, but they increased public scrutiny of how infant formulas are produced and monitored.Is There a Deadline to File a NEC Lawsuit?
There is no single nationwide deadline. Each state has its own statute of limitations and, in some cases, a statute of repose. These laws can limit how long a family has to file a product-liability or wrongful-death claim, and the clock often starts around the time of diagnosis, treatment, or discovery that formula may have contributed to the child's NEC. Because these deadlines can be strict and vary by state, many families consult a lawyer promptly rather than waiting.How to Find a NEC Baby Formula Lawyer on Your Own
OpenClassActions.com is a consumer news site. We do not refer cases, we are not a law firm, and we do not recommend any specific firm. If you want legal advice about a NEC case, you can find a qualified attorney on your own:• Start with your state bar. Most state bar associations run a lawyer referral service and an online directory you can use to find attorneys licensed in your state and confirm they are in good standing.
• Look for relevant experience. NEC cases are product-liability and personal-injury matters, many tied to MDL 3026. Ask whether a firm has handled NEC or pharmaceutical/medical product-liability litigation.
• Ask how fees work. Most product-liability firms work on a contingency-fee basis, meaning no upfront legal fees and the lawyer is paid a percentage only if there is a recovery. Always get the fee agreement in writing and read it carefully.
• Bring your records. Gather NICU and hospital records, NEC diagnosis and surgery reports, documentation of which formulas were used, and related bills so an attorney can evaluate the case.
• Mind the deadline. Confirm your state's statute of limitations early, since waiting can jeopardize a claim.

What is the Enfamil and Similac NEC lawsuit about?
NEC baby formula lawsuits allege that cow's-milk-based products such as Enfamil and Similac can increase the risk of necrotizing enterocolitis in premature babies and that manufacturers did not provide adequate warnings. These are unproven allegations; Abbott and Mead Johnson deny wrongdoing. The federal cases are consolidated in MDL 3026 in the Northern District of Illinois.
Who may qualify for a NEC baby formula claim?
A family may have a potential claim if a child was born premature or with low birth weight, received Enfamil, Similac, or other cow's-milk-based formula or fortifier (often in a NICU), and later developed necrotizing enterocolitis that required treatment or surgery. Only a licensed attorney can evaluate whether a specific case qualifies.
Is there a settlement or claim form for the NEC baby formula lawsuits?
No. There is no global settlement and no class-wide claim form. NEC cases proceed as individual lawsuits, many of them consolidated in MDL 3026 for pretrial purposes. A fourth federal bellwether, Inman v. Mead Johnson, went to trial beginning July 6, 2026.
Is there a deadline to file an NEC baby formula lawsuit?
Yes. Each state has its own statute of limitations and sometimes a statute of repose. The deadline often runs from the time of diagnosis, treatment, or when a family learned that formula may have contributed to the child's NEC. Because these deadlines can be strict, families typically consult a lawyer promptly.
How do I find a lawyer for a NEC baby formula case?
OpenClassActions.com does not refer cases or recommend a specific firm. You can find an attorney on your own through your state bar association's lawyer referral service, by searching for firms experienced in product-liability or MDL 3026 litigation, and by confirming the lawyer's standing and fee terms before signing anything. Most product-liability firms work on contingency, meaning no upfront fees.
