A study of Microbial Contamination and drug sensitivity in Broilers in Modern Slaughter House in Khartoum State

Abstract

This study was planned to investigate presence of bacterial contamination of broilers breast, back, leg and neck during slaughtering process. A total of 154 swab samples were taken after hanging in slaughter area, after bleeding, after scalding, after defeathering, after evisceration, after washing, after chilling, from slaughtering knives, scalding water, packing machine and hands of the workers. Total viable counts (TVCs) and isolation and identification of bacteria were used. All isolates were tested for some antibiotics ( gentamyin, amoxicillin, ciprofloxacin, vancomycin, erythromycin, penicillin, chloranphenicol). The results revealed no statistical difference (P >0.05) between sites of the carcasses and critical points during slaughtering process. The isolated bacteria were E.coli, Salmonella spp. , Proteous spp. , Pseudomonas spp. and Staphylococcus spp. The poultry carcasses can be contaminated at any stage of slaughtering process. Therefore, hygienic measures must be managed to safe broiler meat for human consumption
