Results of investigations supported by the Centers for Disease Control and Prevention for 54 cases of invasive Cronobacter infections among infants, United States, 1989–2018*

Sample type Sample type tested Sample yielded Cronobacter Sample isolate indistinguishable from clinical isolate†
PIF from opened containers 46/52 (87) 10/46 (22)‡ 6/7 (86)
Breast pump collection kit/pump-expressed breastmilk 5/52 (9) 2/5 (40) 1/2(50)
Water from opened bottle 16/52 (27) 2/16 (13) 1/1 (100)
Environmental surfaces 17/52 (31) 6/17 (35)§ 4/6 (67)

*Values are no. positive/no. tested (%). Results from first source investigation in the United States was reported in 1989 (8).
†Comparison made using pulsed-field gel electrophoresis.
‡Cronobacter contamination was identified in powdered infant formula during investigations conducted during 1989–2017.
§Of 6 cases that yielded an isolate from an environmental surface, 4 were from kitchen sink surfaces, 1 from a pacifier, and 1 from a bottle nipple.
