A 181-page amended shareholder derivative lawsuit has been filed in federal court against Abbott Laboratories by court-appointed lead plaintiffs after the company closed a Michigan infant formula manufacturing facility due to FDA concerns over contamination.

On Feb. 15, 2022, Abbott closed its Sturgis, Michigan, plant, and two days later, issued a voluntary recall of contaminated infant formula products. The shutdown and recall were the results of FDA inspections that found multiple regulatory violations and the deaths of several infants who consumed tainted baby formula, according to the opinion.
