Reckitt Benckiser's Mead Johnson Nutrition is recalling approximately 675,000 cans of Nutramigen Powder due to potential contamination with Cronobacter sakazakii bacteria. No illnesses have been reported, and tests for Cronobacter in the suspected batches were negative. The FDA has stated that mandatory testing does not guarantee the absence of bacteria due to potential uneven distribution of low-level contamination. The recall is not expected to significantly affect the U.S. supply of powdered infant formulas.
