I think, but don’t know, that salmonella is much more serious, prolonged, etc.
I’m pretty laid back with my kids, they don’t have to wash their hands after stroking animals or getting muddy, playing in the pond, etc.
That said, I have no doubt that chickens, all animals can carry all sorts of bugs and bacteria, probably very many unnamed, bound to be some human pathogens. Sorry, no help at all!
