Outbreak of Salmonella Enteritidis Infection Linked to Tiramisu Cakes Contaminated by Liquid Eggs in Taiwan, 2014

Taiwan CDC identified a cluster of Salmonella enterica serovar Enteritidis in northern Taiwan on May 15, 2014, which had an indistinguishable, novel pulsed-field gel electrophoresis (PFGE) subtyping pattern. We conducted a case-control study using structured hypothesis-generating interviews, and environmental and trace-back investigations. We defined confirmed cases as patients with culture-confirmed of S. Enteritidis (SEX.238) infection and whose illness onset were during April–May, 2014. The presumptive control cases were recruited from a pilot survey in September 2013 to February 2014 for locally-acquired hepatitis A patients using the similar questionnaire.
