In February 2022, Abbott recalled several infant formula brands and shut its plant in Sturgis, Michigan, the largest formula plant in the United States. The FDA had received reports of infants infected with Cronobacter sakazakii, a bacterium that is dangerous to newborns. Two of those infants died, a tragedy for the families involved that sits over every other fact in this story. Inspectors subsequently found Cronobacter at several locations inside the plant, standing water on floors, and a long-standing crack in a spray dryer. A former employee had filed a complaint months earlier alleging sanitation failures and records that did not reflect reality.
In fairness to everyone involved, genome sequencing never conclusively matched the bacteria in the reported cases to the strains found in the plant. The operational lesson stands either way. The plant remained closed for roughly five months under an FDA consent decree, and because Sturgis supplied such a large share of the market, the shutdown contributed to a formula shortage severe enough that the government flew product in from Europe. A single plant's compliance failure became part of a national supply crisis.
