Abstract
|
|
|
|
Pathogenic Escherichia coli (PEc) is a leadingcause of both foodborne and waterborne illness. In September2012, a major foodborne outbreak with PEc occurred,affecting approximately 1,200 students and food handlersfrom 7 schools in Gyeonggi province, South Korea causedby contaminated kimchi. For detection of PEc in kimchi,real-time polymerase chain reaction (RT-PCR) and traditionalculture methods were used. EAEC and ETEC genotypeswere identified in samples from individuals with the illnessand in kimchi using conventional PCR. Bacteria in stoolsamples were genetically similar to bacteria from kimchi(98% homology). PEc from kimchi was identified as thecausative agent of a foodborne outbreak in South Korea. Asignificant link between kimchi and individuals with foodborneillnesses after consuming kimchi was demonstrated.
