ÇANAKKALE BÖLGESİNDEN ALINAN MİDYE VE DENİZ SUYU ÖRNEKLERİNİN MİKROBİYOLOJİK KALİTELERİNİN BELİRLENMESİ

Bu çalışmada Çanakkale bölgesinde belirlenen 9 farklı istasyondan toplanan 536 midye örneğinin ve her istasyondan alınan deniz suyunun mikrobiyolojik kalitesi belirlenmiştir. Midye örneklerinin toplam mezofilik aerobik bakteri yükünün en yüksek Merkez İskele istasyonunda (3.56 log kob/g) olduğu belirlenmiştir. En yüksek E. coli varlığı ise Gelibolu istasyonunda (1.99 log kob/g) saptanmıştır. Midyelerin mikrobiyel yüklerinin toplandıkları istasyonlar arasında istatistiksel anlamda farklı olmadığı (P>0.05) görülmüştür. Midyelerin toplam mezofilik aerobik bakteri sayısı ile toplandıkları deniz suyunun toplam mezofilik aerobik bakteri sayısı arasında pozitif yönde korelasyon tespit edilmiştir (P<0.05). Gelibolu ve Lapseki istasyonlarındaki mikrobiyel yükün diğer istasyonlara göre daha yüksek olduğu saptanmıştır. Genel olarak değerlendirildiğinde Gelibolu ve Lapseki bölgesi haricinde Çanakkale boğazının farklı noktalarından alınan midyelerin mikrobiyel kalitesinin yasal sınırlar içerisinde olduğu belirlenmiştir.

DETERMINATION OF THE MICROBIOLOGICAL QUALITY OF MUSSELS AND SEAWATER SAMPLES RECEIVED FROM ÇANAKKALE REGION

In this study, the microbiological quality of 536 mussel samples collected from 9 different stations in Çanakkale region and the sea water taken from each station were determined. It was determined that the highest total aerobic mesophilic bacterial count of mussel samples was at the Merkez İskele station (3.56 log cfu/g). However the highest E. coli presence was detected at Gelibolu station (1.99 log cfu/g). It was determined that the microbial loads of mussels were not statistically different between the stations where they were collected (P>0.05). A positive correlation was found between the total bacterial count of mussels and the total bacterial count of seawater they were collected (P<0.05). It was observed that the microbial load at Gelibolu and Lapseki stations was higher than other stations. In general, it was determined that mussels taken from different points of Hellespont, Çanakkale except Gelibolu and Lapseki region was within the legal limits.
