In regard to their connection with NEC, no, Enfamil and Similac have not been recalled.  In early 2022, Abbott Nutrition did voluntarily recall a few lots of their formulas manufactured in their Sturgis, MI, after four babies suffered Cronobacter sakazakii infections and one baby became infected with Salmonella Newport. Two of the babies died, and the FDA and Abbott are still investigating. Currently, The FDA is advising consumers to not use Similac, Alimentum, or EleCare powdered infant formulas if: The first two digits of the code on the container are 22 through 37 The code contains K8, SH or Z2 The expiration date is April 1, 2022 or later
