A total of 40 New Zealand white rabbits, 20 freshly slaughtered rabbits from an experimental farm and 20 processed rabbit carcases from grocery stores in Beni-Suef city, were examined bacteriologically. The mean values of aerobic plate counts at 37 degrees C and 1 degrees C, Enterobacteriaceae counts, Pseudomonas counts and Staphylococcus counts of freshly slaughtered rabbits were 10(4) +/- 2 x 10(3), 8 x 10(2) +/- 10(2), 6 x 10(2) +/- 10(2), 3 x 10(2) +/- 10(2), and 10(2) +/- 60 organisms per gram respectively, whereas the equivalent values were 8 x 10(5) +/- 3 x 10(4), 2 x 10(5) +/- 10(4), 4 x 10(4) +/- 8 x 10(3), 2 x 10(4) +/- 6 x 10(3), and 4 x 10(3) +/- 4 x 10(2) organisms per gram of processed rabbit carcases from grocery stores, respectively. The freshly slaughtered rabbits showed a low bacterial load compared with processed rabbit carcases from grocery stores. Escherichia coli and Listeria monocytogenes could be isolated from the rabbit carcases examined in addition to Salmonella typhimurium, Pseudomonas aeruginosa and Staphylococcus aureus from processed rabbit carcases. Yersinia enterocolitica could not be isolated from any sample examined. Suggested measures to reduce the microbial load in rabbit carcases are discussed.
对总共40只新西兰白兔进行了细菌学检查，其中20只来自实验农场的刚宰杀的兔子，20只来自贝尼苏韦夫市杂货店的加工兔 carcasses。刚宰杀兔子在37摄氏度和1摄氏度下的需氧平板计数平均值、肠杆菌科计数、假单胞菌计数和葡萄球菌计数分别为每克10(4)±2×10(3)、8×10(2)±10(2)、6×10(2)±10(2)、3×10(2)±10(2)和10(2)±60个生物体，而来自杂货店加工兔 carcasses每克的相应值分别为8×10(5)±3×10(4)、2×10(5)±10(4)、4×10(4)±8×10(3)、2×10(4)±6×10(3)和4×10(3)±4×10(2)个生物体。与杂货店加工兔 carcasses相比，刚宰杀的兔子细菌载量较低。除了从加工兔 carcasses中检出鼠伤寒沙门氏菌、铜绿假单胞菌和金黄色葡萄球菌外，还能从所检查的兔 carcasses中分离出大肠杆菌和单核细胞增生李斯特菌。在所检查的任何样本中均未分离出小肠结肠炎耶尔森菌。讨论了降低兔 carcasses微生物载量的建议措施。
