The Research of Listeria Monocytogenes in the Fresh Meat of the Broilers in Poultry Abattoir Konsoni in Kosova

Abstract

This study is initiated to define the level of contamination and possible contaminant factors of broiler's fresh meat with Listeria monocytogenes in poultry's abattoir Konsoni and realized from November 2013 to march 2014, where 72 samples of the fresh meat were tested. These samples were taken from carcasses of the broilers in abattoir during the process of slaughter in different phases. The analytical procedure is realized by using the norm horizontal method ISO 11290. From 72 samples analyzed, 18 samples resulted positive for Listeria spp. Biochemical test and CAMP-test confirmed 7 samples positive for Listeria monocytogenes. From all the samples analyzed, when expressing them in a percentage 25% resulted positive for Listeria spp, whereas 9.72% are positive with Listeria monocytogenes. The data taken tell that from 18 positive samples,16 of them were taken after the phase of eviscerating or as it is called ―cold part of the abattoir. The presence of the Listeria monocytogenes in the ―cold parts of the abattoir is related to the psychrophile nature of listeria. From the data gained we can conclude that the main origin of Listeria monocytogenes are the broilers itself, which they carry this bacterium in their viscera and after the evisceration it contaminates the carcasses and the premises of the abattoir.
