Cross - Contamination with Salmonella on Broiler Slaughterhouse during Processing in Khartoum State.

Abstract

A broiler slaughterhouse was investigated for the presence of Salmonella spp. Two hundred and sixteen (216) samples were collected from broiler carcasses for identification of the isolate and bacterial viable count of Khartoum state, during June2012 to July 2012. The obtained results showed that the concerned bacteria were determined in different operation (six CCPs) and sites (leg, breast and back) respectively. There were at significance differences between these operations and site (P-value 0.05). The mean total viable count of bacteria after chilling at leg, breast and back sites were 3.90±0.53, 4.35±1.06 and 3.10±0.12 log10 CFU/cm2, in after evisceration at leg, breast and back were 3.42±0.51, 4.33±0.52 and 3.27±0.16 log10CFU/cm2, respectively, with statically significant different (P < 0.05). Also there were statically significant different (P< 0.05) after bleeding and hands of worker. In addition the highest average prevalence was after chilling 94.4%, after evisceration 91.7 %, after defeathering 86.1%.
