Cronobacter multispecies complex (Cronobacter) is a member of the Enterobacteriaceae family that was described as a new genus in 2007 [ 1]. Consumption of contaminated powdered infant formula (PIF) has been associated with invasive Cronobacter infection in infants [ 1, 2]. The Food and Agricultural Organization and World Health Organization expert consultations in 2004 and 2006 concluded that Cronobacter contamination of PIF did cause infection and disease in infants [ 2]. Although the presence of Cronobacter in PIF is well documented, the nature of this organism may lead to exposure through other sources [ 1, 3]. Our case illustrates a rare example of Cronobacter bacteremia in an exclusively breastfed infant of a healthcare worker.
