Earlier this year, Mead Johnson was hit with a $60 million verdict and Abbott Laboratories with an even larger $495 million verdict in trials linking the milk-based infant formula the companies make with necrotizing enterocolitis, or NEC—a life-threatening intestinal disease that affects premature infants.

This week, in a third trial bringing similar claims against both companies, a lawyer for the plaintiff asked state court jurors in St. Louis, Missouri, for $6.2 billion in punitive damages in closing arguments. But, after four hours of deliberations last week, jurors returned a complete defense verdict for the companies.
