Route of contamination all responsible for outbreaks: animals (run-off, bird droppings, organic fertilizers such as animal manures. Introduce pathogens directly to the field: irrigation water quality. Fecal matter, soil, sewage overflow introduce pathogens to water: soil. Animal feces or present in the soil. Direct contamination when splashed on produce: human handling.
