In the ME universe I get the impression that these other worlds are likely at least going to cause some sort of minor poisonous reaction. Shepard wouldn't likely get diseases [maybe a virus] but just breathing in pollen, drinking unfiltered water, etc. could cause issues. Just like a Quarian can't eat our food we may have a similar reaction just walking around unprotected in their environment.
It's possible some things may cause reactions to Shepard, but it's absolutely impossible for him to get a virus. The way viruses work is that they hijack cells and use them to replicate their own genetic material, and then spread. The whole opposite chirality issue basically renders a human cell "incompatible" to any kind of dextro-chirality virus. The cell doesn't have the "machinery" to create dextro amino-acids, thus the virus can't replicate and spread.
Viruses rarely affect more than one species; and when you factor in the opposite chirality, it's basically impossible. You know the "L" piece in tetris? It'd be like trying to fit a "reverse L" piece into a slot meant for a normal "L" piece. Just can't happen.
In the Mass Effect universe it's not as easy to say as that. The Omega plauge went after virtually all species regardless of DNA type. We don't know if the plague was from a bacteria, a virus, or something else. If eating a Quarian peanut can make you sick what happens when a bug flies into your mouth, you're stung and injected with native venom, etc. There are so many possible issues I wouldn't be so quick to play these things down.
Note: I don't fault your logic in how you are arguing. I'm just saying the writers in the ME universe may not follow the rules. From the "impression" that I'm getting [YMMV] it may not be as easy as many people think to live in that environment given the rules that I "GUESS" the ME plays under.
Also Note: In ME1 we have a couple of examples of garden worlds that can't be settled by any other species because they don't react well to the native environment. Therefore the precedent has been set that there could be problems.
Devil's Advocate: It's possible that we could also get the smurfy ending. I doubt it but it's obviously possible.
