Identification of bacterial isolates in poultry portioning operations in khartoum state, Sudan

This study aimed to identify the bacterial isolates in poultry portioning operations from February 2018 to August 2020 in Khartoum State. Twelve operations of which 6 were chosen from the traditional and 6 from modern sectors to cover the three localities of Khartoum State. A total of 468 swab samples were collected randomly, of which 288 swab samples for isolation of Salmonella and E coli and 180 swab samples for isolation of campylobacter spp. The results revealed high contamination of work surfaces with Salmonella Spp. after portioning in the traditional sector compared to modern sector 6 (100.0%) and 3 (50.0%), respectively. Prevalence of suspected isolated Salmonella taken from chicken samples before thawing in the traditional sector was found 10 (27.8%), while it increased to 20 (55.5%) after thawing and to 22 (61.1%) after portioning. Prevalence of suspected isolated Salmonella in chicken samples in the modern sector after portioning was found 23 (63.9%). The result also disclosed that prevalence of isolated E. coli from samples in frozen chicken before portioning was14 (38.9%), decreased to 13 (36.1%) in thawed chicken before portioning and increased to 18 (50.0%) after portioning in the traditional sector. While the prevalence in modern sector for chicken after portioning was found 16 (44.4%). No campylobacter was isolated from samples in both traditional and modern sectors. This study concluded that poultry portioning meat in different processes in Khartoum State was contaminated with E. coli and suspected Salmonella.
