ABSTRACT

This study aimed to evaluate the hygienic biosecurity practices of salmonella contamination in primary production and processing. A total of 32 samples from two broiler farms and their slaughterhouses were randomly collected in Bahri locality, Sudan. Of these, 8 samples from broiler farms (4 feacal, 2 composite litter, 2 boots sock) and 24 samples from slaughterhouses (12 pre-chill carcasses and 12 post-chill carcasses). Salmonella load was carried out in selective media (XLD) after enrichment in Rapapport vasilidus broth. The percentage of Salmonella load from the total number of samples was (34.38%). The result represented 5 (62.5%) Salmonella enumerate from farms samples, 1 (20%) from feacal, 2 (40%) from composite litter and 2(40%) from boot sock. Six (25%) Salmonella enumerate were obtained from slaughterhouses of which 4 (66.7%) from pre-chill carcass and 2 (33.3%) from post-chill carcasses. With respect to farms samples, boot socks and litter yielded the highest percentage of positive results for Salmonella load when compared with feacal samples. In contrast pre-chill carcasses samples were slightly higher in load than post-chill carcasses. There was a significant relationship of Salmonella load in farm and slaughterhouse. Also, the results revealed that the load of Salmonella decreased during different stages of processing plant.
