BELLEVILLE, Ill. (AP) — The families of a three babies sickened by a rare bacterial infection, including a 10-day-old Missouri infant who died, filed a lawsuit Tuesday against the Illinois-based manufacturer of a powdered baby formula that they believe is responsible.

The lawsuit contends the babies were sickened by Cronobacter sakazakii bacteria, which has sometimes been associated with tainted powdered infant formula. The suit alleges that the infants fell ill after consuming different kinds of Enfamil-brand powdered baby formula late last year.
