Özet
Araştırmada, 41 kıyma numunesi, farklı firmalara ait 7 soğutulmuş, 25 dondurulmuş toplam 32 hamburger köfte ve 29 soğutulmuş, 17 dondurulmuş toplam 46 İnegöl köfte numunesi E coli 0157:H7 kontaminasyonu ile toplam mezofilik aerobik bakteri ve koliform bakterisi yönünden incelendi. Kıyma numunelerinin 1 tanesinde (%2,43), soğutulmuş İnegöl köftelerin 3 tanesinde (%10,34), dondurulmuş inegöl köftelerin % 1 tanesinde (%5.88), dondurulmuş hamburger köftelerin 3 tanesinde (%12) E coli 0157 serotipi tespit edildi. E coli 0157 pozitif numunelerin hiçbirisinin H7 serotipi olmadığı belirlendi. Araştırmada İnegöl köfte numunelerinin soğutulmuş olarak tüketime sunulanlarında tespit edilen toplam mezofilik aerobik bakteri ortalama sayısı (1.57 x107) gerek dondurulmuş inegöl köftelerden (7.4 x106) gerekse dondurulmuş (3.1 x106) ve soğutulmuş (3.3. x106) olarak tüketime sunulan hamburger köftelerden fazla bulundu. Koliform bakterisi ortalama sayısı ile koliform bakterisi ile kontamine numune sayısı, soğutulmuş olarak muhafaza edilen İnegöl köftelerde kıyma ve hamburger köfte numunelerine göre oldukça yüksek bulundu. Sonuç olarak, incelenen numunelerde E coli 0157:H7 serotipine rastlanmamasına rağmen, E. coli 0157 serotipinin inegöl köfteler (% 8.69) ile hamburger köftelerde (% 9.37) bir hammadde olan kıyma numunelerine (%2.43) göre yüksek oranda bulunması ve soğutulmuş İnegöl köftelerdeki mikrobiyolojik yükün fazlalığı, bu ürünlerin hijyenik koşullar altında üretilmediğini göstermektedir.
In this study, totally 41 minced meat, 32 hamburger balls (7 refrigerated, 25 frozen) and 46 Inegol meat balls (29 refrigerated, 17 frozen) were investigated for contamination of E coli 0157:H7, total mesophilic aerobic and coliform bacteria. One sample of minced meat (2.43%), 3 samples of refrigerated Inegol meat balls (10.34%), 1 samp­le of frozen Inegol meat balls (5.88%) and 3 samples of frozen hamburger balls (12%) were positive for E coli O157 serotype. E coli 0157 serotype was not detected in refrigerated hamburger balls. And also H7 serotype was not de­tected in all E coli 0157 positive samples. TMA counts of Inegol meat balls were 1.57x107 for refrigerated samples and 7.4x106 cfu/g for frozen samples. TMA counts of hamburger balls were found as 3.1x106 for frozen samples and 3.3x106 for refrigerated samples. Counts of coliform bacteria and coliform contaminated samples in Inegol meat balls were found higher than minced meat and hamburger ball samples. As a result, although E coli 0157:H7 was not de­tected in all samples, E coli 0157 serotype was found as 8.69% for Inegol meat balls, 9.37% for hamburger balls and 2.43% for minced meat samples. Higher coliform bacteria contamination of Inegol meat balls and hamburger samples than minced meat and highest microbiological counts in Inegol meat balls show that hygienic conditions were low in the production of these meat products.
