The FDA and CDC continue to investigate four cases, one each in Illinois, Missouri, Oklahoma and Florida. Unfortunately, the babies infected in Missouri and Florida died. It is still unclear where exactly the bacteria came from in each of the separate cases.
There are normally 4-6 cases each year of Cronobacter infection in babies, reported eFoodAlert. In 2011, the CDC noted 12 cases, likely because of an increased awareness of the bacteria.
The CDC said it is testing other formulas that the babies consumed but isnâ€™t releasing names at this time.
