From the CDC..."Cronobacter multi-species complex (formerly Enterobacter sakazakii) is a group of gram-negative bacteria that exists in the environment and which can survive in very dry conditions. The natural habitat for Cronobacter is not known. It has been found in a variety of dry foods, including powdered infant formula, skimmed milk powder, herbal teas, and starches. It has also been found in wastewater. Cronobacter illnesses are rare [2 to 4 cases per year], but they are frequently lethal for infants and can be serious among people with immunocompromising conditions and the elderly."
Cronobacter can cause diarrhea and urinary tract infections in people of all ages, but infection can be very serious in infants (<12 months), especially during the first few weeks after birth. Although cases are rare, the organism can cause a dangerous blood infection (sepsis) or make the linings surrounding the brain and spinal cord swell (meningitis).
"Cronobacter infections have been associated with consumption of reconstituted powdered infant formula. In several outbreak investigations, Cronobacter has been found in powdered infant formula that had been contaminated in the factory. In other cases, Cronobacter might have contaminated the powdered infant formula after it was opened at home or elsewhere. Powdered infant formula is not sterile. Manufacturers report that, using current methods, it is not possible to produce sterile powdered infant formula. At the factory, Cronobacter could get into formula powder if contaminated raw materials are used to make the formula, or if the formula powder touches a contaminated surface in the manufacturing environment."
