Pathogens, on as researchers established, together with juice of a plant form microbic biofilms which show strong resistance to washing off.
During typical five-day refrigerated storage on leaves of the packed salad scientists found about hundred thousand separate bacteria of Salmonella enterica.

Initially salmonellas get on lettuce leaves in case of their cultivation in the open ground. There they get thanks to insects, birds and through fertilizers. However, according to authors of a research, Salmonella enterica can get on leaves and from the processed flowing water.
