Bu çalışmada, Türkiye’nin Adana ilinde perakende satışı yapılan 65 adet taze ürün örneğinde (yapraklı sebzeler, hazır karışık salatalar ve meyveler), Gram- negatif bakteri varlığı araştırılmıştır. Salmonella spp. hiç bir örnekte bulunmamıştır. Ancak, Klebsiella pneumoniae (%22), Stenotrophomonas maltophilia (%15), Citrobacter freundii (%11), E. coli (%11), Klebsiella oxytoca (%11), Acinetobacter spp. [A. baumannii, A. pittii, (%7)], Pseudomonas putida (%7) baskın mikroorganizmalar olup, örneklerin (19/65) %29.2’sinde MALDI-TOF sistemi ile tespit edilmiştir. Bakteri sayıları 3.6 ile 8.3 log CFU/g arasında bulunmuştur. Enterobacter ludwigii (%4), Delftia lacustris (%4), Burkholderia cenocepacia (%4) ve Burkholderia vietnamiensis (%4) suşları ise daha az oranda tespit edilmiştir. Sonuçlarımız Adana ilinde üretilen meyve ve sebzelerin, Salmonella spp. açısından Türk Gıda Kodeksi mikrobiyolojik kriterlerine genel olarak uygun olduğunu, ancak E. coli sayısının daha yüksek olduğunu (5.8 ile 6.3 log CFU/g arasında) ortaya koymuştur. Ayrıca, Escherichia coli, Acinetobacter spp., Klebsiella pneumoniae, Citrobacter freundii ve Stenotrophomonas maltophilia türleri, insan sağlığı için riskli olabilir.

In this study, 65 samples of fresh products (leafy vegetables, ready-to-eat mixed salads, and fruits) retailed in Adana province of Turkiye were investigated for presence of Gram-negative bacteria. Salmonella spp. was undetected in any samples. However, Klebsiella pneumoniae (22%), Stenotrophomonas maltophilia (15%), Citrobacter freundii (11%), E. coli (11%), Klebsiella oxytoca (11%), Acinetobacter spp. [A. baumannii, A. pittii, (7%)], Pseudomonas putida (7%), were the predominant microorganisms and were detected in (19/65) 29.2% of samples by MALDI-TOF system. Their bacterial counts were between 3.6 and 8.3 log CFU/g. Strains of Enterobacter ludwigii (4%), Delftia lacustris (4%), Burkholderia cenocepacia (4%), and Burkholderia vietnamiensis (4%) were less detected. Our results revealed the fruits and vegetables produced in Adana province generally comply with microbiological criteria of the Turkish Food Codex interms of Salmonella spp., but higher bacterial counst of E. coli (between 5.8 and 6.3 log CFU/g) was found. Besides, Escherichia coli, Acinetobacter spp., Klebsiella pneumoniae, Citrobacter freundii, and Stenotrophomonas maltophilia species could be risky to human health.
