Abstract
Fish meal is obtained by processing and drying fish that are not suitable for
human consumption or waste left over from the fishing industry. Fish meal
creates a suitable breeding environment for microorganisms due to both the
high level of nutrients they contain and the processes applied during
production. Aerobic Colony Count (Cob g-1) of fish meal obtained from four
different factories (A, B, C and D) producing fish meal in the Black Sea
region were determined as 4.9x105, 9.7x104, 2.76x105 and 9.8x102,
respectively. Enterobacteria Colony Count (Cfu g-1) and Coliform Bacteria
Count E. coli (Cob g-1) levels were similarly found to be <10. Both Listeria
monocytogenes and Salmonella spp. wasn’t detected in fish meals. While
Rhizopus spp. and Trichoderma spp. fungi were detected in fish meal
obtained from only one factory. Fusarium spp. and Penicillium spp. fungi
were detected in all fish meals. Total Organism Numbers vary between 7x103
and 5x104 Colonies/ml. According to macroscopic and microscopic
examinations, no material that should not be included in feed for animal
nutrition, especially mold, was found in fish meal. As a result, it is seen that
the fish meal produced in the Black Sea Region of Turkey is of extremely
high quality in terms of microbiological and macroscopik and is also suitable
for animal nutrition. Therefore, in this study was pointed out to the
microbiological content and quality of fish meal in the Black Sea Region,
where a significant portion of fish meal is produced in our country.
