Bu çalışmada Şanlıurfa'da satışa sunulan yoğurtlarda Listeria spp. varlığını ve sıklığını belirlemek ve real-time PCR kullanılarak identifikasyonu amaçlanmıştır. Semt pazarları ve marketlerden toplanan, toplam 62 adet yoğurt örne-ğinde Listeria spp. varlığını belirlemek için ISO 11290-1/A1-2004 tarafından önerilen iki aşamalı bir seçici zenginleştir-me kullanılmıştır. Listeria spp. olarak izole edilen kolonilerden elde edilen DNA’lar kullanılarak yapılan real-time PCR yöntemi ile Listeria monocytogenes identifikasyonu gerçekleştirilmiştir. İncelenen yoğurt örneklerinde Listeria spp. pre-valansı %3.2 (2 örnek) olarak bulunmuştur. Şüpheli kolonilerin ön zenginleştirme broth’tan izole edilen DNA’larla yapı-lan real-time PCR çalışmasında, bu iki Listeria spp. izolatı L. monocytogenes olarak identifiye edilmiştir. Yoğurt örnek-leri 4oC’de 10 gün süreyle muhafaza edilmiş ve pozitif örnekler inkübasyonun birinci, üçüncü ve onuncu günlerinde pH, izolasyon ve real-time PCR ile identifikasyon tekrarlanmıştır. Çalışmamız; Şanlıurfa ilindeki semt marketleri ve pazar-larda satılan yoğurtlarda Listeria spp. türlerinin yaygınlığını göstermesinin yanında, Listeria spp. türleri moleküler yön-temle daha hızlı identifiye edilmiş ve insan sağlığı açısından çok tehlikeli olan L. monocytogenes’in yoğurtta varlığını ve bu yolla insanlarda ciddi gıda kaynaklı hastalıklara neden olabileceği gerçeğini göstermiştir.
