Van'da tüketime sunulan dondurmalarda bazı patojenlerin varlığının araştırılması

Bu çalışmada, Van'da perakende satılan hazır kıymalarda Escherichia coli O157'nin varlığı araştırılmıştır. Bunun için, kasap ve marketlerden sağlanan 150 adeti dana ve 150 adeti koyun olmak üzere toplam 300 adet kıyma örneği incelenmiştir. Örneklerin analizinde, Novobiocin katkılı Tryptone Soy Broth ile Cefimixe-Tellurit Supplement içeren Sorbitol MacKonkey Agar ve methyl-umbellipherylglucorunidase ilave edilmiş Violet Red Bile Agar kullanılmıştır. İndol pozitif, sorbitol ve fi-glukoronidaze negatif (366 nm) ve O157 lateks aglütinasyon test kiti ile aglütinasyon oluşturan koloniler E. coli O157 olarak identifiye edilmiştir. E. coli O157 dana kıyma örneklerinde % 4,66 (7/150) oranında, koyun kıymalarında ise % 2 (3/150) oranında belirlenmiştir. Sonuçlar, hazır kıymaların Escherichia coli 0157 ile kontaminasyon oranın azımsanmayacak düzeyde olduğunu ve halk sağlığı açısından risk taşıdığını göstermiştir.

An investigation on the presence of some pathogens in ice cream consumed in Van

In this study, the prevalence of Escherichia coli O157 was investigated in 150 calf minced meat and 150 lamb minced meat samples obtained from retail markets and butcheries in Van. Tryptone Soy Broth added with Novobiocin, Sorbitol MacKonkey Agar with Cefimixe-Tellurit Supplement and Violet Red Bile Agar with methyl-umbellipherylglucorunidase were used for the analysis of the samples. The colonies that were indol (+), sorbitol (-) and fi-glukoronidase (-; 366 nm) and made agglutination with O157 lateks agglutination test kit were identified as E. coli O157. E. coli O157 (4,66 %) was found in calf minced meat samples. In lamb minced meat samples E. coli O157 (2 %) was found. These results clearly reveal that contamination of minced meat by E. coli O157 is quite high and pose the health risks for consumers.
