Salmonella is commonly found in a variety of food products and is a major cause of bacterial foodborne illness throughout the world. In this study, we investigated the prevalence and diversity of Salmonella in eight different food types: sheep ground meat, cow ground meat, chicken meat, cow offal, traditional Sanliurfa cheese, unripened feta cheese, pistachios, and isot (a spice blend of dried red peppers specific to Sanliurfa), traditionally and commonly consumed in Turkey. Among 192 food samples, Salmonella was detected in 59 samples, with the highest prevalence in raw poultry parts (58%) and offal (58%) samples, while Salmonella was not detected in pistachios and dried red pepper. Resultant Salmonella isolates were characterized by serotyping, multilocus sequence typing (MLST), and pulsed-field gel electrophoresis (PFGE). Ten different serotypes represented 10 MLST sequence types (STs) with 1 novel ST and 17 PFGE types. Antimicrobial resistance profiling revealed that 30.5% of the isolates were resistant to two or more antimicrobials. Salmonella enterica subsp. enterica serotype Telaviv, which is rare throughout the world, was the second most common serotype isolated from food samples in this study, suggesting that this serotype might be one of the subtypes that is endemic to Turkey.

Molecular evaluation and antimicrobial susceptibility testing of Escherichia coli isolates from food products in Turkey Kyere, Emmanuel Owusu; Bulut, Ece; AVŞAROĞLU ERKAN, MÜRŞİDE DİLEK; Soyer, Yeşim (Springer Science and Business Media LLC, 2015-06-01) Some strains of Escherichia coli can be important food borne pathogens. Characterization and antimicrobial resistance testing of 28 E. coli isolates from random food samples obtained in Van, Turkey were performed. Primers for 6 indicator genes (fliC, stx1, stx2, eae, hlyA, and rfbE) for shiga toxin-producing E. coli and 5 indicator genes for each pathogroup (bfpA, aggR, ipaH, daaD, st, and lt) were used. E. coli isolates were also typed using pulsed field gel electrophoresis with the XbaI restriction enzyme...
Effect of controlled athmosphere storage,modified athmosphere packaging and gaseous ozone treatment on the survival characteristics of Salmonella enteritidis ay cherry tomatoes Daş, Elif; Gürakan, Candan; Department of Food Engineering (2004) In recent years, outbreaks of infections associated with raw and minimally processed fruits and vegetables have been reported. Possible sources for contamination are irrigation water, manure, wash water, handling by workers and contact with contaminated surfaces. Pathogens can occur on raw and minimally processed produce at populations ranging from 103 to 109 CFU/g and able to survive and sometimes grow under various storage conditions. The objective of this study was to analyse the growth/survival of Salmo...
Emergence, Distribution, and Molecular and Phenotypic Characteristics of Salmonella enterica Serotype 4,5,12:i:- Switt, Andrea I. Moreno; Soyer, Yeşim; Warnick, Lorin D.; Wiedmann, Martin (Mary Ann Liebert Inc, 2009-05-01) Salmonella spp. represent one of the most common causes of bacterial foodborne illnesses around the world. The species Salmonella enterica contains more than 2500 serotypes, and emergence of new human pathogenic Salmonella strains and serotypes represents a major public health issue. Salmonella enterica subsp. enterica serotype 4,5,12:i:- represents a monophasic variant of Salmonella Typhimurium, which has rarely been identified before the mid-1990s. The prevalence of this serotype among human salmonellosis...
Interactions of high hydrostatic pressure, pressurization temperature and pH on death and injury of pressure-resistant and pressure-sensitive strains of foodborne pathogens Alpas, Hami; BOZOGLU, F; RAY, B (Elsevier BV, 2000-09-15) The objective of this: study is to determine the interactions between high hydrostatic pressure, pressurization temperature, time and pH during pressurization on death and injury of pressure-resistant and pressure-sensitive strains of four foodborne pathogens: Staphylococcus aureus 485 and 765, Listeria monocytogenes CA and OH2, Escherichia coli O157:H7 933 and 931, Salmonella enteritidis FDA and Salmonella typhimurium E21274. Among these strains S. aureus 485, L. monocytogenes CA, E, coli O157:H7 933 and S...
Subtyping of salmonella isolated from human clinical and animal non-clinical cases, as well as different food samples using pulsed field gel electrophoresis (PFGE) / Bulut, Ece; Soyer, Yeşim; Özcengiz, Gülay; Department of Biotechnology (2014) Salmonella is one of the most reported pathogens in foodborne outbreaks worldwide. In order to ensure safety of foods, farm-to-fork surveillance and control systems must be utilized. Development of numerous typing methods have improved the ability to detect salmonellosis outbreaks, enabling to trace the contaminated source from farm to fork. Facilitating prevention and regulation of techniques, knowledge of the epidemiology, genetics and ecology of Salmonella infections depend on the information provided by...
