Özet:

In this study, the aim is to make a meta-analysis of the prevalence of Cronobacter sakazakii found in various foods offered for consumption in Turkey. The C. sakazakii prevalence, which was determined in independent studies, was combined and the common prevalence shortening for Turkey was provided and inter-study heterogeneities were investigated. The study material was made by 22 studies in which the prevalence of C. sakazakii was determined in Turkey between 2008-2019 and 2463 food samples studied in these studies. As a result of the meta-analysis, the common prevalence value of C. sakazakii was 0.033 (95% confidence range; 0.021-0.044) In the reviewed studies, baby food, raw materials used in the production of baby food, milk and dairy products and meat and meat products were identified as subgroups because there were sufficient prevalence data and the meta-regression analysis between subgroups was applied. According to the findings of the study, the prevalence of C. sakazakii in Turkey; baby food, baby food raw materials, milk and dairy products and meat and meat products, respectively, 0.01 (0.00-0.01), 0.11 (0.04-0.18), 0.05 (0.02-0.08) and 0.03 (0.00-0.06). The heterogeneity they have shown depending on the sample size of the studies on the presence of C. sakazakii in foods offered for consumption in Turkey has been eliminated and the common prevalence of the pathogen in Turkey has been calculated. The study concluded that the factor was epidemically important and that the effective implementation of food safety management systems in the production chain was necessary for public health.

In this study, it is aimed to make meta-analysis of the prevalence of Cronobacter sakazakii in various foods consumed in Turkey. The prevalences of C. sakazakii detected in the different independent studies were combined to provide a common prevalence estimate and heterogeneities between studies were investigated. The study material consisted of 22 studies investigating C. sakazakii prevalence in a total of 2463 food samples included infant formula, infant formula ingredients, milk and dairy products and meat and meat products between the years 1997-2019 was carried out in Turkey. As a result of the meta-analysis, the common prevalence of C. sakazakii was detected as (%95 Confidence Interval; 0.021-0.044) for all studies. In the evaluated studies, infant formula, infant formula ingredients, milk and dairy products and meat and meat products were identified as sub-groups due to sufficient prevalence data and meta-regression analysis was applied between sub-groups. Accordingly, the prevalence of C. sakazakii in infant formula, infant formula ingredients, milk and dairy products and meat and meat products were determined as 0.01 (0.00-0.01), 0.11 (0.04-0.18), 0.05 (0.02-0.08) and 0.03 (0.00-0.06) in Turkey, respectively. Heterogeneities due to sampling size of studies on the presence of C. sakazakii in foods consumed in Turkey were corrected and main prevalence of the pathogen in Turkey is calculated. The study concluded that the pathogen is epidemiologically important and effective implementation of food safety management systems in the food production chain is necessary for public health.
