Campylobacter jejuni Carriage of Broiler Carcasses at Slaughter-house As “An Important Parameter of food Hygiene”

Abstract

The aim of the study is to evaluate the contamination of poultry meat with Campylobacter jejuni during slaughtering. The study was performed from February to August 2011, at Brno –Czech Republic. Two hundred eighty slaughtered broiler carcasses were examined from 20 farms (at different time intervals), five different samples were collected from each carcass. Swab samples were collected from different parts of the carcass as follows: from outer surfaces of carcass (after defeathering); from inner surfaces after evisceration; from ileum; liver and Bile as well.
A total of 139 carcasses were positive from bacteriological isolation of C. jejuni of total carcasses examined. Particularly, the percentage of isolation from different organ samples were as follows: 7.85% of isolates were from the outer surface, 8.21% from internal surface, 28.57% from ileum, 21.07% from liver, and 14.28% from bile.
Also the frequency of isolation was varied according to different months and showed maximum level in May (63%), while the minimum isolation rate was reported in August (40%). The present date was indicated a high level of contamination of broiler carcasses with C. jejuni and give us an alarming signal about and preventive measures
