Niğde ve Kayseri’de Satışa Sunulan Köy ve Market Yumurtalarının Mikrobiyolojik Kalitesi

Year 2018, Volume: 15 Issue: 1, 51 - 57, 15.04.2018

Abstract

Bu çalışmada, market ve köy yumurtalarının mikrobiyolojik kalitelerinin araştırılması amaçlandı. Bu kapsamda,
Niğde ve Kayseri’deki çeşitli market ve açık pazarlardan alınan toplam 200 yumurta (100 market ve 100 köy) örneği
mikrobiyolojik analize tabi tutuldu. Her bir yumurta kabuğu ve içeriği koliform, Escherichia coli, Campylobacter spp.,
Staphylococcus aureus, Salmonella spp. ve maya- küf bakımından incelendi. İncelenen yumurta örneklerinin hiçbirinde
Campylobacter spp. ve S. aureus’a rastlanmazken, bir örnekte (yumurta kabuğu) Salmonella spp. belirlendi. Ayrıca 27
(%13.5) yumurta kabuğunun ve 6 (%3) içeriğinin koliform bakteriler ile sırasıyla 12 (%6) ve 31 (%15.5) yumurta kabuğunun
ise sırasıyla E. coli ve maya- küf ile kontamine olduğu tespit edildi. Koliform, E. coli ve maya- küf sayılarının
ortalama değerleri sırasıyla 3.69-5.62 log kob/mL, 3.35-3.55 log kob/mL, ve 6.80-6.97 log kob/mL olarak belirlendi.
Elde edilen veriler, incelenen yumurta kabuklarındaki mikrobiyel yükün, buzdolabı ve mutfak ortamlarını kontamine
edebileceğini; içerik kontaminasyonlarının ise az pişmiş yumurta tüketimi yoluyla halk sağlığı açısından risk teşkil edebileceğini
ortaya koymaktadır. Bu çalışmada elde edilen verilere dayanarak, marketlerde ve köy pazarlarında satışa
sunulan yumurtaların +8°C'nin altındaki sıcaklıklarda muhafaza edilmesi konusunda gerekli önlemlerin alınması, üretici
ve tüketicilerin yumurtanın soğukta muhafaza edilmesi gereken riskli bir gıda olduğu konusunda bilinçlendirilmesi gerektiği
sonucuna varıldı.

The Microbiological Quality of the Village and Market Eggs Sold at Retail in Nigde and Kayseri

Year 2018, Volume: 15 Issue: 1, 51 - 57, 15.04.2018

Abstract

In this study, it is aimed to investigate the microbiological quality of market and village eggs. A total of 200

eggs (100 market and 100 village) were randomly collected from different markets and village bazaars in Nigde and

Kayseri. Each egg shell and content were investigated for coliform, E. coli. Campylobacter spp., S. aureus, Salmonella

spp. and yeast- mold contaminations. None of the egg samples were contaminated with Campylobacter spp. and S.

aureus while Salmonella spp. was determined in one sample (eggshell). In addition, it was determined that 27 (13.5%)

egg shells and 6 (3%) egg contents were found contaminated with coliforms, where 12 (6%) and 31 (15.5%) of the egg

shells were found contaminated with E. coli and yeast and mold respectively. Total coliform, E. coli and yeast- mold

counts were detected to range from 3.69 to 5.62 log cfu/mL, 3.35 to 3.55 log cfu/mL and 6.80 to 6.97 log cfu/mL, respectively.

Obtained data revealed that the microbiological load on egg shells may lead to contaminations in refigerator

and kitchen environments while egg content contaminations may constitute a risk for public health through undercooked

egg consumption. In conclusion, preventive measures must be taken to keep both market and village eggs

under +8 °C during storage, besides, producers and consumer’s awareness should be raised about the fact that egg is

also a risky food that must be kept cold.
