Preterm infants fed cow’s milk-based baby formulas by Similac or Enfamil are more likely to develop necrotizing enterocolitis (NEC), a serious gastrointestinal illness that occurs mostly in premature babies.
Shouse Law Group is helping parents bring claims against the manufacturers Abbott and Mead Johnson for defective design and failing to warn doctors and parents about the increased risk of NEC in preemies.
We are pursuing the highest financial settlement allowable under the law.

1. Which formulas are linked to NEC in premature babies?
Cow’s milk-based formulas – such as Enfamil and Similac – make it more likely that premature babies (before 37 full weeks) will suffer from the bowel disease necrotizing enterocolitis (NEC). NEC typically develops in preemies being fed this formula when they are two-to-six weeks old.
Neonatal intensive care units (NICUs) often rely on cow-milk formula – which is high in calories – to provide preemies with nutrition and immune support and to help them gain weight. This formula is also used to supplement nutrition for breastfeeding preemies with difficulties latching.1
Similac products that contain cow’s milk ingredients are:
- Similac Alimentum
- Similac Alimentum Expert Care
- Similac Human Milk Fortifier
- Similac Human Milk Fortifier Concentrated Liquid
- Similac Human Milk Fortifier Hydrolyzed Protein- Concentrated Liquid
- Similac Human Milk Fortifier Powder
- Similac Liquid Protein Fortifier
- Similac NeoSure
- Similac Special Care
- Similac Special Care 20
- Similac Special Care 24
- Similac Special Care 24 High ProteinSimilac Special Care 30
Enfamil products that contain cow’s milk ingredients are:
- Enfamil 24 and DHA & ARA Supplement
- Enfamil Human Milk Fortifier Acidified Liquid
- Enfamil Human Milk Fortifier Powder
- Enfamil Human Milk Fortifier Liquid High Protein
- Enfamil Milk Fortifier Liquid Standard Protein
- Enfamil NeuroPro Enfacare
- Enfacare Powder
- Enfamil Premature 20 Cal
- Enfamil Premature 24 Cal
- Enfamil Premature 24 Cal/fl oz HP
- Enfamil Premature 30 Cal
The product name “Human Milk Fortifier” is very misleading. A reasonable person might presume it contains human milk, but it does not.
2. What is NEC?
NEC – short for necrotizing enterocolitis – is a gastrointestinal bacterial infection that largely affects premature babies.
This life-threatening illness causes inflammation, tissue death of the intestines, and perforation of the wall of the intestines. NEC begins in the intestinal wall’s inner lining, and it affects the intestines’ thickness.
- ceasing feedings (fasting),
- administering antibiotics and IV fluids and nutrition,
- draining abdominal fluids,
- nasogastric drainage,
- circulatory support, and
- possibly abdominal repair surgery.
NEC – if caught and treated quickly – can be curable with no complications.
Possible consequences of NEC – or the surgery to treat NEC – include:
- Sepsis (from intestinal bacteria draining out into the abdominal cavity)
- Peritonitis (an abdominal infection)
- Narrowing of the intestinal wall, called intestinal stricture
- Short bowel syndrome, which may cause malabsorption (and may require a bowel transplant)
- Holes in the intestines (causing waste to leak out)
- Neurodevelopmental problems
- Cerebral palsy
- Organ failure or damage caused by decreased oxygen supply
- Growth failure
- Liver failure (IFALD)
- Death (if the NEC is not treated quickly) up to 50% of the time
Potential symptoms of NEC are:
- Not gaining weight
- Trouble eating/feeding residuals
- Bloody diarrhea or dark stools
- Ileus (decreased sounds in the bowel)
- Yellow or green vomit
- Pain, redness, tenderness and/or swelling (distension) in the abdomen
- Low breathing, temperature, blood pressure (hypotension), and heart rate (bradycardia)
- Metabolic acidosis
- Green fluid in the abdominal wall
- Apnea (paused breathing)
- Lowered peripheral perfusion
Symptoms of advanced NEC include:
- Abdominal wall erythema
- Cardiovascular collapse
NEC is diagnosed through:
- blood tests and cultures
- abdominal imaging (CT scans, PET scans, ultrasounds)
- blood gas level tests
- a physician’s clinical observations
Of the 480,000 preterm infants born every year in the United States, about 9,000 come down with NEC. Ninety percent of those NEC cases occur in preterm infants.
The four types of NEC are 1) classic NEC; 2) transfusion-associated NEC; 3) Atypical NEC; and 4) Term infant NEC. Most of the bovine formula-related cases involve “classic NEC.”
NEC can also develop as a result of being born with underdeveloped intestines or from oxygen deprivation during labor and delivery.2
3. Does baby formula cause NEC?
Scientific studies indicate that cow’s milk-based (“bovine”) formulas trigger more incidents of NEC in preemies than donor breast milk. A study going back to 1990 that followed 926 preterm infants showed that:
- Formula-fed preemies were six to ten times more likely to get NEC than preemies who were fed breast milk.
- Formula-fed premies were three times more likely to get NEC than preemies who received both breast milk and formula.3
In 2011, several hospitals concluded that NEC was less of a risk for very premature babies fed human donor milk than for those fed cow milk.4
Also in 2011, The U.S. Surgeon General stated, “For vulnerable premature infants, formula feeding is associated with higher rates of necrotizing enterocolitis (NEC).”
In 2012, a policy statement by the American Academy of Pediatrics said that preemies should be given only human milk due to NEC risks from bovine milk formula.5
4. What is the current state of the litigation?
Several parents have brought lawsuits against makers of cow’s milk-based baby formulas including Abbott Laboratories, Inc. (maker of Similac) and Mead Johnson & Company, LLC (maker of Enfamil) for causing their preterm babies to get sick or die from NEC. Common causes of action include:
- Strict product liability for design defect (defective product) because there was a reasonable alternative design
- Strict liability for failure to warn
- Intentional misrepresentation
- Negligent misrepresentation
- Breach of warranty
- Wrongful death (if the infant died)
The strongest product liability lawsuit claim is design defect. This is because the academic scholarship is clear that human milk increases the risk of NEC in preemies, yet Abbott and Mead persisted in manufacturing and selling it.
Abbott and Mead are sure to argue that the design defect claim is “preempted” by the Infant Formula Act because the FDA approved the formula for sale. This is a losing argument according to past case law.
Plaintiffs’ attorneys are also pushing the “failure to warn” claim. These cow’s milk-based formulas have no warning labels revealing the NEC risks. Abbott and Mead Johnson knew – or should have known – about the risks of bovine-based formulas on preemies, and they deliberately omitted adequate warnings.
With all of the scientific evidence linking human milk to NEC in preemies, Abbott and Mead Abbott and Meadhad an obligation to warn about their products’ hazards and dangers. Had there been an adequate warning on the products’ labels, neonatologists and pediatricians may have instead chosen human donor milk.6
Abbott and Mead are expected to argue that the “failure to warn” claim is defeated by the “learned intermediary doctrine” – which puts the onus on doctors to warn patients of risks. Even still, this doctrine does not relieve Abbott and Mead of the duty to warn doctors themselves.
Furthermore, it was never an undue hardship for Abbott or Mead Johnson to add a warning label disclosing the NEC risks. Baby formula is regulated as a food rather than as a drug. So adding a warning would have been an easy process under the United States Federal Food, Drug, and Cosmetic Act (FDCA).
Multi-district litigations (MDL)
In 2022, all the infant formula lawsuits against Abbott and Mead are joining into an MDL, short for multi-district litigation, out of the Northern District of Illinois before Judge Rebecca Pallmeyer. The MDL number is 3026.
Consolidating similar cases into an MDL is a way to expedite litigation by having one federal judge make all the pretrial discovery decisions. Eventually a few cases will go to trial, where juries will determine liability and the extent of any compensatory- and punitive damages. How these bellwether trials pan out will then set the stage for out-of-court global settlement talks.
If the bellwether juries find for the plaintiffs and return large financial awards, then all the other plaintiffs in the MDL will have the upper hand in negotiations. In sum, the more successful the bellwether trials, the higher the settlements for the remaining MDL plaintiffs. Also, the defendants may be anxious to resolve these cases quickly to curb public relations damages.
Note that many parents are also choosing to sue their medical providers for medical malpractice for feeding their preterm infants cow’s milk-based formula. Several of these “med mal” verdicts and settlements have been in the low millions.
Since juries tend to be less sympathetic to multi-billion-dollar Big Pharma companies than to physicians and their staff, hopefully any verdicts and settlements from the anticipated MDLs will be even higher.
5. How much money can I get?
The baby formula lawsuits against Abbott and Mead for causing NEC seek compensatory damages to cover medical bills (including ongoing care), any other out-of-pocket costs, and pain and suffering.
No price can be put on a baby’s life and well-being – or on the emotional distress a child’s illness or death causes – so plaintiffs’ attorneys will be fighting for the largest settlement for financial compensation possible under the law.
Depending on the extent of the baby’s injuries, we will be pursuing six- and seven-figure settlements for economic- and non-economic damages.
6. What is the statute of limitations to sue?
The statute of limitations to file a NEC baby formula lawsuit turns on various factors, including:
- which state the injury occurred in (the time limit to sue can be as short as one year after the injury);
- who is filing the lawsuit (the parents, an estate, or the child – sometimes children have up to 21 years to sue);
- when the plaintiffs discovered the NEC (“discovery rule”); and
- any other facts that may pause (“toll”) the statute of limitations from running.
Therefore, anyone who believes they have grounds to sue should consult an attorney right away. A lawyer can determine the deadline to bring a legal action.
7. Has the baby formula been recalled?
No. No bovine-based baby formula products have been recalled for their connection to damaging intestinal tissues in pre-term infants.7
An alternative to cow milk formula is Prolacta, which includes
- a human milk-based fortifier that has been available for sale since 2006 and
- a ready-to-feed formula that has been available since 2014.
Pasteurized human donor milk can be bought through the Human Milk Banking Association of North America and the European Milk Bank Association.
An unrelated recall in 2021 involved the Able Group, which pulled its Kendamil, Bioland, Holle, and HiPP formulas for having insufficient iron. There was no warning to parents about the need to supplement with iron.
In 2018, CVS pulled its Enfamil products after a tampering incident where the powdered formula had been replaced with flour. Then in 2012, some babies came down with Cronobacter sakazakii after taking Enfamil, but the FDA said there was no connection.8
8. Other baby food-related lawsuits
There are an increasing number of individual lawsuits and traditional class action lawsuits against manufacturers of baby food products for selling food with dangerous levels of toxic elements. Parents are claiming that these baby food companies caused their child’s autism or brain damage. These lawsuits are largely out of the U.S. District federal court for the Eastern District of New York.
A congressional report released on February 4, 2021, revealed that certain baby foods have high levels of the toxic heavy metals:
- cadmium, and
This subcommittee report says that according to the U.S. Food and Drug Administration (FDA), these four toxic heavy metals are dangerous – particularly to babies. They can cause irreversible brain damage and other health problems.
The baby food manufacturers and baby food brand names listed in this congressional report include:
- Beech-Nut Nutrition Company,
- Earth’s Best Organic (Hain Celestial Group Inc.),
- HappyBABY (Nurture, Inc.),
- Happy Family Organics (Nurture, Inc.),
- Parent’s Choice (Perrigo),
- Plum Organics (Campbell Soup Company), and
- Sprout Organic Foods.
Baby food maker Beach-Nut issued a voluntary recall of some of its infant rice cereals because of arsenic problems.9
On February 17, 2022, Abbott recalled Similac baby formulas manufactured at a Michigan facility after reports of Cronobacter sakazakii bacteria and Salmonella. Abbott is also recalling Alimentum and EleCare baby formulas manufactured at its Sturgis plant.10

- There have recently been baby formula recalls unrelated to the bovine formula-NEC issues: On August 8, 2021, the Able Group (HiPP, Holle, Bioland, Kendamil) recalled various products for having low iron levels in violation of FDA requirements. Some affected products with insufficient amount of iron include Hipp Comfort Milk Formula, Combiotic First Infant Milk Formula, HiPP Dutch Stage 1 Combiotic Infant Milk Formula, HiPP German Stage 1 Combiotic Infant Milk Formula, Holle Bio Stage PRE Organic Infant Milk Formula, and more. Babies fed these recalled products risk developing insufficient iron levels and iron deficiency anemia and other negative functional development outcomes. All lot codes have been recalled. These products were imported from Europe and purchased through the littlebundle website, not at retail stores like Walmart or Costco. Parents who used these products are encouraged to consult with their doctors to test whether their babies have enough iron.
