ובה"א
and he himself explained it thus: it means without washing the hands or cleaning the mouth [between the eating of the one and the other].
Shulchan Arukh, Yoreh De'ah
Even with meat of a wild animal and a bird it is forbidden to put them on a table where one is eating cheese, so that he doesn't come to eat them together. But [to put] on a table that's meant for arranging cooked foods, it is permitted to put one next to the other.
