Is it possible for aperson to be allergic to Red ear slider turtles?

My father and law keeps on making companints that its my turtles that making everyone sick in the house...I caught bronchitis but i dnt BELIEVE its from the turtles and yet he says hes very allergic to them...first he kept on saying that he hated the water splashing from the filter and i fixed that and from there it moved to the actual tutles and he wanted them out. Is he making up exuses because he simply wants everything his way? Or does he actualy have reason to complain because when I fix one thing he complains about the other and guess what...he smokes and he believes turtle pee is worse.
