Microbiological hazard evaluation represented by the psychrotrophic germs from the level of avian carcasses.

Abstract

The aim of this study was to evaluate the psychrotr ophic germ contamination level from the level of refrigerated broiler carcasses. The research materi al was represented by 24 broiler carcass samples co llected in November 2006 - May 2008 period, from a slaughterhouse in Cluj County. Following the statistic interp retation of gathered data we found that the psychrotrophic l oad was sitauated between 2.88±0.32 log ufc/g and 4 .32±0.42 log ufc/g. From the psychrotrophic bacteria group w e found that the pseudomonads are predominant, the level of contamination is relatively low, comprised between 2.92±0.27 log ufc/g and 4.24±0.31 log ufc/g. Regard ing the bacterial configuration at the surface of broiler c arcasses, we found that Gram negative germs are pre dominant - 70.26 %, while Gram positive species wer of a perce nt of 29.44 %. From the Gram positive group, 7.01 % are staphilococcs, 3.44% streptococcs, 8.77% micrococcs and 10.52% acid-lactic bacteria.
