Afyonkarahisar'da tüketime sunulan çiğ süt ve peynirlerde E.coli 0157:H7 varlığının belirlenmesi

Bu çalışmada, Afyonkarahisar il merkezinde bulunan çeşitli bakkal ile marketlerden satın alınan 100 adet çiğ süt ve semt pazarlarından satın alınan 100 adet beyaz peynir örneğinde E. coli 0157:H7 varlığı ve yaygınlığı araştırılmıştır. E. coli O157:H7’nin izolasyon ve identifikasyonu’nda İmmuno Manyetik Separasyon (İMS) metodu ile Amerikan Gıda ve İlaç Dairesinin (Food and Drug Administiration/FDA) önerdiği metot kullanılmıştır. Analize alınan 100 adet çiğ süt örneğinden 3’ünde (%3) ve 100 adet peynir örneğinden 1’inde (%1) E. coli O157:H7 tespit edilmiştir. Sonuç olarak, çiğ süt ile beyaz peynirlerin E. coli O157:H7 ile bulaşmada kaynak olabileceği ve halk sağlığı açısından potansiyel bir tehdit oluşturabileceği kanaatine varılmıştır.

Anahtar Kelimeler:

peynir, çiğ süt, Escherichia coli, perakende pazarlama, sokak satıcılığı, Afyon

The prevalance of E.coli 0157:H7 in raw milks cheases sold in Afyonkarahisar province,Turkey

The purpose of this study was to identify the presence of E.coli 0157:H7 and its prevalence in raw milk and white cheese for which 100 units of raw milk were bought from the shops and markets of Afyonkarahisar provincial center and 100 white cheese samples were bought from neighborhood and villages markets. E. coli O157:H7 isolation and identification was carried out using the Immunomagnetic Separation (IMS) method and the method recommended by the American Food and Drug Administration (FDA). Out of the 100 raw milk samples, 3 (3%) samples and 1 (1%) of the cheese samples out of 100 were identified with having E. coli O157:H7. It is concluded that the presence of E.coli 0157:H7 in raw milk and white cheeses can be a source of contamination and is a potential public health hazard.
