The distinction is blurred somewhat because the Citadel is the only place where multispecies political structures exist. However, I think that there is clearly some racism and prejudice that grows out of what may have started as political or military conflicts. Balak says, "You humans," not "you colonists" or "you Alliance soldiers." Pressly says he doesn't much like "turians in general," as opposed to criticizing the actions or principles of the Turian Hierarchy.
We can argue over whether specific examples of antagonism between the species are racism per se, but even if some of them aren't, they're still potentially dangerous when they get into the realm of designating certain groups as "us" and others as "them."
It's very hard to distinguish racism from nationalism, as somebody already mentioned salarians(at least their dalatrass) look definityely racist, calling krogans "brutes" and "savages". Wrex also has an understandable hate. I don't think you can call batarians racists because even if Balak hates all humans, it's not that different from i.e. Cold War rhetoric.
It's really hard to find racism except Cerberus and some individuals in ME universe and even in Ceberus case it's implicit. And it is good.
