Dondurularak Satılan Kalamarların (Todarodes pacificus) Mikrobiyel Kalitesi

Bu çalışmada, temizlenmiş ve dondurulmuş kalamar (Todarodes pacificus) örnekleri E. coli, Pseudomonas spp., L. monocytogenes ve koagülaz (+) S. aureus açısından incelenmiştir. Halka şekli verilip strafor tabaklarda dondurularak satılan 100 adet kalamar örneği farklı satış noktalarından toplanarak, soğuk zincir altında laboratuara getirilmiştir. Yaklaşık olarak 500 g ağırlığında ve içerisinde 6-8 cm çapında halka kalamar bulunan her bir strafor tabak bir örnek olarak değerlendirilmiştir. Çalışmada incelenen örneklerin 7’sinde (%7) E. coli, 10’unda (%10) Pseudomonas spp., 8’inde (%8) koagülaz (+) S. aureus ve 5’inde (%5) L. monocytogenes tespit edilmiştir. Kalamar örneklerinde en yüksek E. coli, Pseudomonas spp. ve koagülaz (+) S. aureus sayısı sırasıyla, 4.7x103 KOB/g, 7.0x102 KOB/g ve 8.9x102 KOB/g olarak tespit edilmiştir. Yapılan incelemeler sonucunda, kalamar örneklerinin bir kısmının halk sağlığını tehlikeye sokacak bakterilerle kontamine olduğu belirlenmiştir. Piyasada satılan kalamarların mikrobiyolojik kontrollerinin sıklıkla yapılması ve üretim sırasında kontaminasyonun önüne geçecek tedbirlerin alınması gerektiği ortaya konulmuştur.

Microbial Quality of Frozen Retail Squid (Todarodes pacificus)

In this study, cleaned and frozen squid (Todarodes pacificus) samples were examined for E. coli, Pseudomonas spp., L. monocytogenes and coagulase (+) S. aureus. One hundred squid samples, which were in ring shaped and frozen in styrofoam plates, were collected from different sale points and brought to the laboratory under the cold chain. Each styrofoam dish containing 6-8 cm diameter ring squid with 500 g of weight was regarded as one sample. In the study, 7 samples of E. coli (7%), 10 samples of Pseudomonas spp. (10%), 8 samples of coagulase (+) S. aureus (8%) and 5 samples of L. monocytogenes (5%) were determined in all samples examined. The highest numbers of E. coli Pseudomonas spp. and coagulase (+) S. aureus counts in squid samples, were 4.7x103 KOB/g, 7.0x102 KOB/g and 8.9x102 KOB/g, respectively. Findings indicate that, some of the squid samples were contaminated with bacteria that would endanger public health. It has been showed that microbiological controls of squid sold in the market should be performed frequently and precautions should be taken to prevent contamination during production.
