Increased usage of raw vegetables, without heat treatment, in human nutrition carries the risk of possible infection by pathogenic bacteria. The possibility of persistence of human isolates in vegetable crops represents, in epidemiological sense, a serious source of infection. The aim of this research was to study the possibilities of persistence of human isolates of Pseudomonas aeruginosa in selected vegetable crops, as well as the possibility of bacterial transport from roots to the above-ground part of the plant. Obtained results confirmed the possibility of persistence of human isolates of P. aeruginosa in the aforementioned vegetables.
