Abstract
Analysis of 100 bagged lettuce and spinach samples showed mean total bacterial counts of 7.0 log(10) CFU/g and a broad range of < 4 to 8.3 log10 CFU/g. Most probable numbers (MPN) of > or = 11,000/g coliforms were found in 55 samples, and generic Escherichia coli bacteria were detected in 16 samples, but no E. coli count exceeded 10 MPN/g.
摘要
对100份袋装生菜和菠菜样本的分析显示，细菌总数平均为7.0 log(10) CFU/g，范围广泛，从<4到8.3 log10 CFU/g。在55个样本中发现大肠菌群的最可能数（MPN）≥11,000/g，在16个样本中检测到了大肠杆菌属细菌，但没有大肠杆菌计数超过10 MPN/g。
