=== Notable Ingredient Differences ===
One of the primary distinctions between the brands lies in their specific ingredient compositions. Enfamil's standard formulas typically use a combination of nonfat milk and whey protein concentrate, while many Similac formulas utilize milk protein isolate.<ref name="ref1" /> Both brands include lactose as a carbohydrate source, though some products may also contain corn syrup solids.<ref name="ref1" />

The type and number of prebiotics, which are intended to support gut health, also differ. Some Similac formulas, such as Similac 360, contain five types of Human Milk Oligosaccharides (HMOs), while Enfamil formulas often include a dual-prebiotic blend of galactooligosaccharides (GOS) and polydextrose. Another point of differentiation is the use of palm olein oil. Enfamil includes this ingredient in many of its formulas, whereas Similac has largely removed it from its products, which may help with softer stools in some infants.

=== Recalls and Legal Issues ===
Both Abbott Laboratories and Mead Johnson have faced recalls and legal challenges regarding their infant formulas. In February 2022, Abbott initiated a voluntary recall of some powdered Similac, Alimentum, and EleCare formulas produced at its Sturgis, Michigan facility due to potential contamination with *Cronobacter sakazakii*. This recall and the subsequent plant shutdown were contributing factors to a nationwide infant formula shortage in the United States.

Additionally, both companies have been named in lawsuits alleging that their cow's milk-based formulas contributed to an increased risk of necrotizing enterocolitis (NEC), a serious intestinal condition, in premature infants. In March 2024, a jury awarded $60 million in a lawsuit against Mead Johnson, finding that its Enfamil formula was a cause of NEC in a premature infant who died. As of early 2026, hundreds of lawsuits against both Mead Johnson and Abbott related to NEC were pending.
