从综合医院厨房获得的西红柿、萝卜、芹菜、胡萝卜、菊苣、卷心菜、黄瓜、洋葱和生菜中分离出铜绿假单胞菌，其中西红柿的分离频率和计数最高。厨房工作人员的手上以及他们使用的切菜板和刀具上存在铜绿假单胞菌，表明他们通过接触这些蔬菜而获得了该生物体。据估计，患者平均食用一份番茄沙拉可能会摄入多达 5 × 103 个菌落形成单位的铜绿假单胞菌。从临床标本中分离出的铜绿假单胞菌的绿脓杆菌类型通常与从蔬菜中回收的绿脓杆菌相同，因此表明番茄和其他蔬菜是铜绿假单胞菌在患者肠道定殖的重要来源和载体。
Pseudomonas aeruginosa was isolated from tomatoes, radishes, celery, carrots, endive, cabbage, cucumbers, onions, and lettuce obtained from the kitchen of a general hospital, with tomatoes yielding both highest frequencies of isolation and highest counts. Presence of P. aeruginosa on the hands of kitchen personnel and cutting boards and knives which they used suggests acquisition of the organism through contact with these vegetables. It is estimated that a patient consuming an average portion of tomato salad might ingest as many as 5 � 103 colony-forming units of P. aeruginosa. Pyocine types of P. aeruginosa isolated from clinical specimens were frequently identical to those recovered from vegetables, thus implicating tomatoes and other vegetables as an important source and vehicle by which P. aeruginosa colonizes the intestinal tract of patients.
