poultry, and most animal species, have salmonella in their digestive tracts. as a result, their fecal material has salmonella. any humans who handle poultry can become contaminated with the salmonella and if it enters their digestive tract (as with kids sucking thumbs, people eating food without washing hands first, kissing birds, etc) they become sick with the salmonella. that is how human salmonellosis occurs. the poultry flocks have salmonella – they don’t need to be exposed to human excreta in order to get salmonella in their digestive tracts.
the same thing can happen if people handle turtles or snakes – they have salmonella as well. if that gets into the humans stomach by improper handing of the reptiles, they too will get salmonellosis.

please provide more information , that will be more helpful.
thanks so much
