Abstract

Verocytotoxin-producing Escherichia coli (VTEC) are important pathogens that cause serious publichealth risks such as food poisoning. Raw milk and cheeses made from raw or inadequately pasteurizedmilk remain a potential vehicle for VTEC serotype O157 infections. In this study, the occurrence of E.coli serotype O157 was investigated in a total of 245 Turkish homemade white cheeses, produced inrural areas, which were collected from various open public bazaars. Twenty-one non-sorbitol fermentingcolonies were detected as suspicious E. coli O157 isolates on the sorbitol MacConkey Agar supplementedwith cefxime and tellurite (CT-SMAC). Presumptive E. coli O157 isolates were tested for agglutinationaccording to the manufacturers instructions with a commercial E. coli O157 latex test. E. coli O157 wasnot detected in any of the 245 Turkish homemade white cheeses, popular food consumed by Turkish people.In conclusion, it is pleasing to note the absence of E. coli O157 in all of this popular food. However, itmay be advisable to carry out a careful surveillance in such food in view of consumers health and thepossible presence of E. coli O157:H7, an important foodborne pathogen.

Özet

Verositotoksin üreten Escherichia coli (VTEC) gıda zehirlenmeleri gibi ciddi halk sağlığı risklerine nedenolan önemli patojendir. Çiğ süt ile çiğ sütten ya da yeterli derecede pastörize edilmemiş sütten yapılanpeynirler VTEC serotip E. coli O157 enfeksiyonları için potansiyel bir kaynak teşkil etmektedir. Buçalışmada, kırsal kesimde üretilen toplam 245 adet Türk ev yapımı beyaz peynir örneği çeşitli açık halkpazarlarından toplanmıştır. Toplanan örnekler E. coli serotip O157nin varlığı açısıdan araştırılmıştır.Sefksim-tellürite (CT) ihtiva eden sorbitol MacConkey (CT-SMAC) besiyerinden sorbitolü fermenteetmeyen toplam 21 koloni E. coli O157 varlığı açısından şüpheli izolat olarak tespit edildi. E. coli O157varlığı açısından şüpheli izolatlar ticari E. coli O157 lateks aglütinasyon test kitine üreticinin talimatlarıdoğrultusunda tabi tutuldu. Türk halkı tarafından sevilerek tüketilen toplam 245 Türk ev yapımı beyazpeynirin hiçbirinde E. coli O157 varlığı tayin edilmedi. Sonuç olarak, bu sevilen gıdada E. coli O157ninyokluğu sevindirici bir tespittir. Bununla beraber, gıdalarda tüketici sağlığı için önemli bir gıda kaynaklıpatojen olan E. coli O157:H7nin varlığına yönelik titiz incelemenin gerçekleştirilmesi tavsiye edilir.
