Salmonella usually enters agricultural environments via animal feces. Animals can directly contaminate plants or surface water used for irrigation and pesticide or fertilizer diluent through contaminated feces.What plant am I thinking of that ends up with salmonella or something equally bad?
The ability to colonize plants may be an effective survival and multiplication strategy for Salmonella as it provides a link between its excretion in the environment via animal feces and the recontamination of herbivorous and omnivorous hosts.
Interactions of Salmonella with animals and plants
So essentially it still needs an animal to shit on the plant that is infected with salmonella in the first place. Then the bacteria can invade the plant, even multiply only to be eaten by another animal to popegate the species lifecycle.
