Abstract

During 2003-2009, we identified 544 cases of Cronobacter spp. infection from 6 US states. The highest percentage of invasive infections occurred among children <5 years of age; urine isolates predominated among adults. Rates of invasive infections among infants approximate earlier estimates. Overall incidence of 0.66 cases/100,000 population was higher than anticipated.

Isolations of Cronobacter spp., by specimen source and patient age group, Foodborne Diseases Active Surveillance Network (FoodNet), 2003–2009. Data are based on a sample from laboratories in 6 states (California, Colorado, Maryland, Minnesota, New Mexico, and Tennessee) in the FoodNet catchment area and are reported for 535 of 544 patients (age information missing for 9 patients). Width of the column is proportional to the number of isolations. CSF, cerebrospinal fluid.
