A microbiological survey was performed on 4 selected imported spices: black peppercorns, white peppercorns, coriander, and fennel seed. Aerobic plate count values ranged from 10(4) to 10(7) colony-forming units (CFU)/g for black and white peppercorns and from 10(3) to 10(5) CFU/g for coriander and fennel seed. Combined results of the 3-tube most probable number procedure and the API 20E kit indicated the presence of Escherichia coli in 4 test samples of black peppercorns, 1 test sample of white peppercorns, and 1 test sample of coriander. Two test samples of black peppercorns were positive for Salmonella contamination. Among the various Enterobacteriaceae isolated from the spices, Enterobacter cloacae and Klebsiella pneumoniae were found most frequently in all spice types. Of 18 mammalian and avian fecal pellets removed from the spices and analyzed microbiologically, E. coli was found in only 2 pellet specimens. There was no apparent relationship between the enteric microflora found in spices and those found in the fecal pellets.
对4种选定的进口香料进行了微生物学调查:黑胡椒、白胡椒、芫荽籽和小茴香籽。黑胡椒和白胡椒的需氧平板计数数值范围为10⁴至10⁷菌落形成单位(CFU)/克,芫荽籽和小茴香籽的需氧平板计数数值范围为10³至10⁵CFU/克。3管最大可能数法和API 20E试剂盒的综合结果表明,4份黑胡椒测试样品、1份白胡椒测试样品和1份芫荽籽测试样品中存在大肠杆菌。两份黑胡椒测试样品沙门氏菌污染呈阳性。在从香料中分离出的各种肠杆菌科细菌中,阴沟肠杆菌和肺炎克雷伯菌在所有香料类型中最为常见。从香料中取出并进行微生物分析的18个哺乳动物和鸟类粪便颗粒中,仅在2个颗粒样本中发现了大肠杆菌。香料中发现的肠道微生物群与粪便颗粒中发现的肠道微生物群之间没有明显关系。
