Abstract: Cronobacter spp. involves a group of opportunistic pathogens that cause meningitis in newborns, immunosuppressed individuals with a mortality rate of 50-80%. Seven species like C. sakazakii, C. malonaticus, C. muytjensii, C. turicensis, C. dublinensis, C. universalis, C. condimenti are included in this genus which has been a subject of research especially in the bacteriologic analysis of baby foods. However, since these species were detected also in prepared foodstuffs. The objective of this study was to assert the presence of Cronobacter spp. in foodstuff offered for sale in Turkey. A total of 151 prepared foodstuffs including a variety of spice, flour, instant soup were purchased from different sales points. The presence of Cronobacter spp. were investigated in these samples. Cronobacter suspected isolates which were obtained by microbiological analyses were confirmed by PCR targeted to gyrB gene and were then identified by multiplex PCR. Prevalence of Cronobacter spp was estimated to be 17.88%. Out of 27 Cronobacter spp. isolates obtained, 13(48.1%), 6(22.2%), 5(18.5%), 3(11.1%) belonged to C. sakazakii, C. muytjensii, C. turicensis, C. malonaticus species, respectively. Consequently, the presence of the bacteria in widely consumed foodstuff revealed that Cronobacter spp. is subject to monitoring due to its opportunistic nature in terms of public health concern.
