The present study surveyed the occurrence of Cronobacter spp. in dried foods including milk powder, spices and herbs and others, and fresh vegetables commercially available in markets, and ground soil materials for the agriculture. Cronobacter spp. were isolated from 15% of 33 spice and herb samples and 3% of 36 taste foods, and these were C. turicensis, C. malonaticus, C. sakazakii and C. dubliensis. Cronobacter spp. from fresh vegetables were detected in 12% of field vegetables and 13% of hydroponic vegetables. C. turicensis was prevalent in field vegetables, and C. malonaticus was in hydroponic ones. And, Cronobacter spp. in shredded vegetables were detected from 44% of 9 samples, and these were C. dubliensis, C. turicensis and C. sakazakii. Also, Cronobacter spp. in soil from rice field, vegetable field and sandpits were predominantly C. sakazakii and C. malonaticus.
本研究调查了阪崎肠杆菌属在包括奶粉、香料和草药等在内的干燥食品、市场上可买到的新鲜蔬菜以及农业用土壤材料中的存在情况。从33份香料和草药样品的15%以及36份调味食品的3%中分离出了阪崎肠杆菌属，这些菌株为图埃氏阪崎肠杆菌、阪崎肠杆菌、阪崎肠杆菌和都柏林阪崎肠杆菌。在12%的田间蔬菜和13%的水培蔬菜中检测到了来自新鲜蔬菜的阪崎肠杆菌属。图埃氏阪崎肠杆菌在田间蔬菜中占主导，而阪崎肠杆菌在水培蔬菜中占主导。此外，在9份切丝蔬菜样品的44%中检测到了阪崎肠杆菌属，这些菌株为都柏林阪崎肠杆菌、图埃氏阪崎肠杆菌和阪崎肠杆菌。另外，稻田、菜地和沙坑土壤中的阪崎肠杆菌属主要是阪崎肠杆菌和阪崎肠杆菌。
