Similac NEC Lawsuits: Judge Orders Retrial After Defense Misconduct, Bellwether Trials Looming 2025
A Troubling Trend: NEC in Premature Infants
Necrotizing enterocolitis (NEC), a severe gastrointestinal disease primarily affecting premature infants, is under intense legal scrutiny. Studies have shown that premature babies fed cow’s milk-based formula have an increased risk of developing NEC. This has led to a wave of lawsuits against formula manufacturers, alleging they failed to warn about this deadly risk. As of August 2025, 759 Similac and Enfamil lawsuits are pending multidistrict litigation (MDL).
The Similac NEC Lawsuit Landscape
Parents and caregivers are filing Similac lawsuits against Abbott Laboratories, claiming the company failed to warn that its cow’s milk products could increase the risk of NEC in premature infants. These lawsuits allege that Abbott knew about the risk of necrotizing enterocolitis and failed to warn the public. Plaintiffs seek compensation for medical bills, their child’s loss of quality of life, funeral expenses, and other damages.
Judge Orders Retrial Due to Defense Misconduct
In a significant development, a judge has ordered a retrial in a key Similac NEC lawsuit, erasing the only trial win for formula manufacturers. The judge cited misconduct by the defense team that could have influenced the jury’s decision. This ruling underscores the importance of fair trials and ethical conduct in complex litigation. The judge determined that “misconduct” committed by the defense team could have influenced the jury’s final decision. Abbott and Mead Johnson are appealing the order.
Bellwether Trials on the Horizon
The legal battle is far from over. Bellwether trials, which serve as test cases for the wider litigation, are looming in 2025. These trials will provide insights into how juries might react to evidence presented in all related lawsuits. The outcomes of these bellwether trials could influence potential settlements or further individual trials.
Key Bellwether Trials to Watch:
- Mar v. Abbott Laboratories (Case No. 1:22-cv-00232): Claims premature infant RaiLee Mar died after being fed Similac in the NICU and developing NEC.
- Diggs v. Abbott Laboratories (Case No. 1:22-cv-05356): Involves a Maryland child who allegedly suffered NEC after being fed Similac and Enfamil products, resulting in severe life-long injuries.
- Etienne & Brown v. Abbott Laboratories (Case No. 1:22-cv-02001)
- Inman v. Mead Johnson & Co. (Case No. 1:22-cv-03737)
Recent Developments in the Similac NEC Litigation:
- July 2025: The judge overseeing the baby formula lawsuits in federal court has once again granted summary judgment to Abbot in the second bellwether case.
- March 2025: The only trial win for baby formula manufacturers in the NEC litigation has been erased.
- February 2025: The defendants in the baby formula MDL have filed for summary judgment.
The Science Behind the Lawsuits
The lawsuits are rooted in medical research linking cow milk-based infant formulas like Similac and Enfamil to NEC. Studies have shown that NEC is more common in preterm infants who consume formula versus breast milk. One study said it was six to 10 times more common in exclusively formula-fed babies than in babies who were breastfed. Another study put that number at a 20 times greater risk for preemies fed formula versus breast milk.
What This Means for Families
If your premature baby was diagnosed with NEC after being fed Similac, you may be able to file a lawsuit against Abbott Laboratories. Parents and caregivers are seeking compensation for medical bills, their child’s loss of quality of life, funeral expenses for infants who died from NEC complications, and other damages.
The Importance of Legal Representation
Navigating the complexities of the Similac NEC lawsuits requires experienced legal representation. An attorney can help you understand your rights, gather evidence, and pursue the compensation you deserve.
