Abstract
ABSTRACT
The transmission of
Escherichia coli
O157:H7 from manure-contaminated soil and irrigation water to lettuce plants was demonstrated using laser scanning confocal microscopy, epifluorescence microscopy, and recovery of viable cells from the inner tissues of plants.
E. coli
O157:H7 migrated to internal locations in plant tissue and was thus protected from the action of sanitizing agents by virtue of its inaccessibility. Experiments demonstrate that
E. coli
O157:H7 can enter the lettuce plant through the root system and migrate throughout the edible portion of the plant.
