Bu çalışmada Elazığ piyasasında satılan konvansiyonel (ticari çiftlik) ve köy yumurtalarının mikrobiyolojik kalitesi, yıl boyunca incelenmiştir. Elazığ ilinde yumurtaların satışa sunulduğu halk pazarlarından, bakkal ve marketlerden her ay 12’şer adet olmak üzere bir yılda toplam 144 market ve 144 köy yumurtası toplanmıştır. Konvansiyonel ve köy yumurtalarının kabuk ve içlerindeki Toplam Mezofilik Aerofilik Bakteri (TMAB), Enterobacteriaceae sayısı ve Salmonella spp. varlığı incelenmiştir. Yıl boyunca incelenen 144 konvansiyonel yumurtanın kabuğunda ortalama TMAB sayısı 4,47 log10/kabuk, köy yumurtası kabuğunda ise 5,15 log10/kabuk bulunmuştur. Yumurta içlerinde ise TMAB sayısı sırasıyla 1,29 log10 kob/ml ve 1,14 log10 kob/ml bulunmuştur. Enterobacteriaceae sayıları konvansiyonel yumurta kabuğunda 1,23 log10/kabuk iken köy yumurtası kabuğunda 1,30 log10/kabuk bulunmuş, yumurta içeriklerinde ise sırasıyla 0,71 ve 0,70 log10 kob/ml olarak tespit edilmiştir. Tüm yıl bulgularında konvansiyonel ve köy yumurtalarında TMAB ortalaması kabuklar için anlamlı farklı bulunmuştur (p<0,05). Enterobacteriaceae sayıları bakımından konvansiyonel ve köy yumurtaları arasında fark bulunmamıştır (p>0,05). Salmonella spp. prevalansı konvansiyonel yumurta kabuğunda %0,69, köy yumurtası kabuklarında %1,39’unda, köy yumurtası içeriklerinde ise %0,69 olarak tespit edilmiştir. Konvansiyonel yumurta içeriklerinde Salmonella spp. bulunmamıştır. Köy yumurtalarında Salmonella spp. prevalansı konvansiyonel yumurtalara göre daha fazla bulunmuştur. Sonuç olarak, konvansiyonel yumurtaların ve yumurta kabuklarının mikrobiyolojik kalite açısından köy yumurtalarına kıyasla daha iyi olduğu ve Salmonella riskinin konvansiyonel yumurtalarda daha az olduğu görülmüştür.
In this study, microbiological quality of conventional (commercial farm egg) and village eggs sold in Elazıg were examined during a year (between January 2018 and December 2018). Each month, 12 village eggs and 12 conventional eggs were collected from public bazar, grocery stores and markets. In total, 144 conventional and 144 village eggs were collected during a year. Total number of Mesophilic Aerobic Bacteria (TMAB), Enterobacteriaceae and Salmonella spp. They were investigated on the eggshells and in the content of eggs. While the average number of TMAB on the eggshells of the conventional eggs was 4.47 log10/eggshell, 5.15 log10/eggshell were found for the village eggs. The number of TMAB was 1.29 log10/ml and 1.14 log10/ml in the content of the eggs, respectively. The number of Enterobacteriaceae was 1.23 and 1.30 log10/eggshell on the conventional and village eggs, respectively. In the egg contents, these numbers were 0.71 and 0.70 log10/ml for the conventional and village eggs, respectively. The significant difference was found in TMAB numbers between the conventional and village eggshells, in point of the entire year results (p<0.05). There was no difference between the conventional and village eggshells in terms of the number of Enterobacteriaceae (p>0.05). In terms of Salmonella spp., statistical difference was not detected both eggshells and egg contents between conventional and village eggs (p>0.05). No salmonella was detected in the egg contents of the conventional eggs. In conclusion, the results revealed that the microbiological quality of the conventional eggs and eggshells were better when compared with the village egg and eggshells, and the Salmonella risk was lower in conventional eggs compared to the village eggs.
