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.

NEC Litigation Update — July 2026
The federal Enfamil and Similac NEC cases are consolidated in a multidistrict litigation, 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. As of mid-2026, roughly 800 NEC baby formula cases were pending in the MDL against Abbott (Similac) and Mead Johnson, now part of Reckitt (Enfamil).• July 2026 federal bellwether: A fourth federal bellwether case, Inman v. Mead Johnson, went to trial beginning July 6, 2026 before Judge Pallmeyer. Reporting describes it as the first Enfamil case to clear summary judgment and the Daubert expert challenge in the federal MDL, so it is the first time plaintiffs' causation experts are expected to reach a federal NEC jury. 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 resolve every case, but their outcomes often shape later settlement discussions.
• 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 appeals court later declined to transfer the case to the Missouri Supreme Court, and Abbott has said it will ask the Missouri Supreme Court to review it, so that 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, finding the company not liable.
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. The statements in these cases remain unproven allegations, and Abbott and Mead Johnson deny wrongdoing.

Did your premature baby develop NEC after formula feeding?
If your child was born premature, given Enfamil, Similac, or other cow's-milk-based formula or fortifier, and later diagnosed with necrotizing enterocolitis, families in this situation have filed product-liability lawsuits seeking compensation for NICU care, surgeries, long-term complications, and other losses. Many cases involve fragile newborns who received these products in the hospital before parents ever knew there could be a higher risk of NEC.This page explains what NEC is, the symptoms and risk factors, and which formulas the lawsuits focus on. For the current status of the litigation, the MDL 3026 bellwether schedule, and step-by-step help finding a lawyer on your own, see our Enfamil and Similac NEC baby formula lawsuit guide.
What are Similac and Enfamil
Similac and Enfamil are two of the most widely used infant formula brands in the United States.Similac is produced by Abbott Laboratories and Enfamil is produced by Mead Johnson, now part of Reckitt. Both offer cow's milk based formulas and fortifiers that are often used in hospitals, NICUs, and at home when breast milk is not available or needs to be supplemented.
These brands have also faced separate class action settlements in the past over serving size and false advertising issues, including the Similac baby formula false advertising settlement and the Enfamil serving size class action settlement.
Who may qualify for an Enfamil or Similac NEC lawsuit
Eligibility for a NEC baby formula lawsuit usually focuses on a few key facts:• A confirmed diagnosis of necrotizing enterocolitis (NEC)
• Premature birth or low birth weight
• Use of cow's milk based formula or human milk fortifier, often in the NICU
• Records showing these products were given before NEC developed
Parents pursuing these claims often report:
• A baby born before 37 weeks or weighing less than 5.5 pounds
• Enfamil or Similac formulas or fortifiers added to breast milk in the hospital
• Sudden symptoms such as abdominal swelling, bloody stool, vomiting, or feeding intolerance
• An NEC diagnosis confirmed by imaging, x rays, or surgical findings
• Emergency surgery to remove damaged or dead intestine in severe cases
If this sounds familiar, a product-liability attorney licensed in your state can review the medical records and explain whether your family may have a claim.
What is necrotizing enterocolitis (NEC)?
Necrotizing enterocolitis is a serious intestinal disease that mostly affects premature babies. It causes inflammation in the lining of the intestines. In severe cases parts of the intestine can become damaged or begin to die, which can lead to perforation, infection, and life threatening complications.NEC is far more common in premature infants and those who receive formula derived from cow's milk instead of exclusive human milk. The condition can progress quickly, which is why early recognition and emergency treatment are so important.
Which baby formulas are under scrutiny
Enfamil and Similac are two of the most widely used formula brands in the United States. Many premature babies receive these products in the hospital or NICU when breast milk is unavailable or when extra calories are needed.Lawsuits claim that cow's milk based formulas and fortifiers from companies such as Abbott Laboratories (Similac) and Mead Johnson (Enfamil) can significantly increase the risk of NEC in premature infants, yet parents and even some caregivers were not adequately warned about these risks.
Some hospital focused products have received special attention in research, including formulas intended for very small premature babies and fortifiers added to human milk. Studies suggest that certain cow's milk based products may be more likely to trigger intestinal problems than human milk or human milk based fortifiers.
Have baby formulas been recalled?
Several baby formulas have been recalled in recent years for safety reasons. In February 2022, Abbott recalled specific lots of Similac, Alimentum, and EleCare after reports of Cronobacter sakazakii infections and infant deaths linked to products produced at its Sturgis, Michigan plant. The plant temporarily shut down while the company and regulators investigated.In October 2022, Abbott announced another recall for certain ready to feed liquid formulas because some bottles may not have been sealed correctly, raising concerns about spoilage and stomach problems.
While these recalls dealt with contamination and packaging issues and not NEC directly, they highlighted broader questions about how infant formulas are manufactured, tested, and monitored for safety.
Warning signs and symptoms of NEC in babies
Recognizing NEC early can make a major difference in outcomes. Parents and caregivers are often told to watch for changes such as:• Abdominal pain or unusual fussiness that is hard to soothe
• A swollen, puffy, or tender belly
• Feeding difficulties or sudden refusal to eat
• Green or yellow vomiting
• 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
In more advanced or severe NEC cases, babies may also have:
• Generalized swelling or fluid retention
• Low sodium or other electrolyte problems
• Kidney issues and high potassium levels
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 the risk of necrotizing enterocolitis, especially in premature infants. These can include:• Premature birth before 37 weeks
• Low birth weight under 5.5 pounds
• Cow's milk based formula or fortifier instead of exclusive human milk
• Serious illness or infections in the NICU
• Hospital outbreaks of harmful bacteria
• Blood transfusions in fragile newborns
• Low oxygen levels around the time of birth
NEC is most common in premature babies in the hospital. It is relatively rare in full term infants. 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 formulas and fortifiers are under legal and medical scrutiny.
What proof helps in NEC baby formula cases
Strong documentation can make it easier for attorneys to review and process a potential NEC claim. Helpful records can include:• NICU and hospital records describing feeding protocol and formulas used
• Chart notes showing when Enfamil, Similac, or other formulas or fortifiers were started
• Medical records confirming the NEC diagnosis
• Imaging, x ray, and surgical reports documenting intestinal damage
• Discharge summaries and follow up notes about ongoing digestive problems or short bowel syndrome
• Bills and statements showing the cost of NICU stays, surgeries, and ongoing care
What types of compensation NEC lawsuits seek
NEC baby formula lawsuits seek compensation for a wide range of losses. Depending on the case, potential damages can include:• Medical expenses: NICU care, surgeries, hospital stays, medications, and specialist visits
• Future medical care: Treatment for long term digestive issues, short bowel syndrome, or other complications
• Pain and suffering: Physical pain, emotional distress, and trauma for both the child and family
• Loss of earnings and support: When a parent must miss work or leave a job to care for a child with serious health needs
• Wrongful death damages: For families who lost a child to NEC complications
Deadlines for NEC baby formula claims
There is no single nationwide deadline for NEC baby formula lawsuits. Each state has its own statutes of limitations and sometimes statutes of repose. These laws can limit how long parents have to file a claim after an NEC diagnosis, surgery or other major NEC treatment, or learning that formula or fortifier could be linked to their child's condition. Because these deadlines can be strict and complex, it is important to speak with an attorney as soon as possible if you believe baby formula may have harmed your child.

What is the Enfamil and Similac NEC lawsuit about?
These lawsuits claim that cow's-milk-based formulas and fortifiers such as Enfamil and Similac increase the risk of necrotizing enterocolitis in premature babies and that manufacturers did not adequately warn parents and providers. Families seek accountability and financial support for the intensive medical care and long-term challenges NEC can cause. These are unproven allegations, and the manufacturers deny wrongdoing.
Who may qualify for a NEC baby formula claim?
You may have a potential claim if your child was born premature, received Enfamil, Similac, or other cow's-milk-based products, and later developed NEC that required medical treatment or surgery. Attorneys look at gestational age, feeding records, the severity of NEC, and long-term outcomes.
What are common signs and symptoms of NEC in babies?
Warning signs of necrotizing enterocolitis can include abdominal swelling, feeding intolerance, vomiting, bloody stool, lethargy, unstable body temperature, breathing changes, and difficulty gaining weight. In severe cases babies may have low blood pressure, electrolyte problems, or require surgery to remove damaged intestine. Any of these signs require immediate medical attention.
Have Enfamil or Similac formulas been recalled for safety issues?
Several Similac products were recalled in 2022 after reports of Cronobacter infections and concerns about improperly sealed bottles. Those recalls focused on contamination and spoilage rather than NEC, but they increased scrutiny of infant formula safety and how these products are manufactured and marketed.
Is there a deadline to file an NEC baby formula lawsuit?
Yes. Statutes of limitations can limit how long you have to file a claim. In many states the clock starts around the time of diagnosis, treatment, or discovery that formula may have contributed to your child's condition. Talking with a lawyer quickly can help you avoid missing important deadlines.
