* Averted in the ''LightNovel/FamiliarOfZero''/''VideoGame/FalloutNewVegas'' crossover ''FanFic/TheFall'', where upon being sent to the [[AfterTheEnd post-nuclear war world of Fallout]], Louise quickly suffers from the radiation filled atmosphere, that the other denezins of the wasteland have had two centuries to build an immunity to and has to take [{FantasticDrug Rad-Away]] regularly just to survive, which unfourtunatley isn't cheap.

** This is also averted with Doc Mitchell, who grew up in one of the vaults, safe from the radiation and took thirty years of constantly using Rad-Away, before he built up an immunity.

* The Zerg Hyperevolutionary Virus from ''Franchise/StarCraft'' is able to infect any alien it comes in contact with. It's also usually paired with a neural parasite. This is Justified by having the virus, as per namesake, evolve rapidly (about a million times more in a week than humans ever have in two million years). And the assumption that everything has DNA to infect. However, it doesn't work on Protoss due to their PsychicPowers supercharging their immune systems.

* The Zerg in ''Franchise/StarCraft'', they are created to thrive in any atmosphere, and even in the vacuum of space. ''VideoGame/StarCraftII'' plays this straight during the invasion of Char. Despite the fact that the entire world is a giant volcanic hotspot, the surface consists of compacted ash and solidified lava, and open pits of lava are the equivalent of oceans... humans can still walk around with open helmets. And the rain is apparently perfectly neutral water rather than the expected acid rain. The Zerg ''might'' have modified the atmosphere more to their liking, but considering they can do fine in a vacuum and evolved on an even worse world, that seems doubtful. Amusingly, General Warfield had specifically stated earlier that the atmosphere could "burn a man alive". Despite the hellish conditions Char was actually a major colony in the Confederacy due to its large supplies of minerals. The Terrans eventually fought a nuclear war over said minerals, waking several previously dormant volcanoes and producing radiation so dangerous in some areas even fully armored Marines can't survive exposure.

** Justified by all sentient species being artificial rather than naturally evolved: the Old Ones and Necrons (who may be closely related in themselves) engineered most sentient life in the universe, though they used different base 'materials' for different species. Anything that attacks those common engineered parts of sentient biology could logically infect more or less anything in the setting but the Tyranids... and the hat of the Tyranids is 'adapts to be compatible with everything' including diseases, so they're logically on the list too.

** Apparently, the volus homeworld is a high-pressure cocktail of ammonia and other caustic gasses; all the volus we see in-game wear high-pressure suits, and it's implied that, without them, their skin would split open from their bodies' internal pressure. Ew.

** Krogans and turiens both evolved on planets that are considerably warmer than Earth. Bring Wrex to the frozen ice planet of Noveria and he complains about the cold more than anyone else in the party, but bring him to the active volcanoes on Therum (surface temperature 59 degrees Celsius!) and he laughs at the way "you mammals" are sweating while saying that it'll take more than that before he actually starts to feel hot.

* Mentioned in ''Literature/OldMansWar'', apparently killing and eating colonists of an alien species who happen to be inhabiting a planet you want is popular in the setting, and humans are just as willing to do it to other species as they are to do it to humans.

* Averted in ''[[Literature/TheSpaceOdysseySeries 2061]]'' by Creator/ArthurCClarke. A spaceship lands on Europa, one of the crew is killed, and the corpse is eaten by a large water creature. Said creature promptly dies, because the biochemical differences means that human flesh is poisonous to it.

* *In ''[[Literature/TheSpaceOdysseySeries 2001]]'' by Creator/ArthurCClarke, Bowman wonders if the artificial food that the Monolith's creators have made for him is safe to eat - explicitly pointing out that while he doesn't think it intends him any harm, biochemistry is very complicated and even a relatively tiny mistake might make something poisonous. As it turned out they didn't make any mistakes and it was safe.

* In ''Anime/GargantiaOnTheVerdurousPlanet,'' the Galactic Alliance of Humanity has never found an actual planet to settle on because of this--which is partly why [[AntiHero Ledo]]'s [[FirstEpisodeSpoiler rediscovery of]] [[EarthThatWas Earth]] is such a big deal. Apparently even their spaceships aren't perfect--when he first wakes up inside a cargo hold and thinks he's in a spaceship, he's surprised to find that it has exactly 1 G.

* In one ''WesternAnimation/RickAndMorty'' episode, Jerry tries to discredit an alien by revealing that he has a heroin dependency. The alien audience is nonplussed--of ''course'' he does. Heroin is a major component of his planet's atmosphere, so naturally he needs to take it artificially when he's off-world.

* The ''Film/MenInBlack'' films and cartoons imply that all alien immigrants and visitors to earth can eat (or appear to eat, in the case of the MobileSuitHuman-wearing Arquelliens) human food, although most of them ''need'' to in order to live as [[{{Muggles}} ordinary humans]]. Presumably those that ''can't'' eat Earth food find more-palatable corners of the galaxy to hang around in.

** Played straight in ''Literature/TheNightsDawnTrilogy'', where many exotic foodstuffs are imported from alien planets, and earth plants are genetically tweaked to grow on other worlds; the best alcoholic beverage in the Human Confederation is made from the water accumulated in the flowers of Norfolk roses. A short tale describes how some of the first scientists to land there, while inspecting the local flora, tasted said water. Norfolk was cleared for colonization days later as a result.

* Played both ways in the Literature/VorkosiganSaga by Creator/LoisMcMasterBujold. The wildlife on the newly discovered earthlike planet Sergyar is edible, but has to be well cooked because native parasites might find humans edible as well. On the other hand, the native flora of the world of Barrayar is hostile to its human inhabitants. Most of the plant life is some shade of red or brown, is completely inedible (and often poisonous to humans), and produce enough environmental toxins that mutation can be a real problem on the planet. Especially during a centuries-long period of isolation from the galactic community leading to the loss of modern medicine. Barrayarans developed a very Sparta-like attitude towards birth defects and deformities as a result.

* Food is [[{{Pun}} played with]] in ''Series/{{Farscape}}''. The human Crichton is forced to subsist on food from a far side of the galaxy which has never even ''heard'' of humans, so therefore wouldn't be expected to have any idea what a human's body can process. Obviously, any time he has a chance to have food from earth--[[MindScrew even if it's all in his own head]]--he consumes it with relish. Additionally, food cubes are a standard processed food source used by ''many'' different species with no noticeable problems - though apparently, the whole idea behind food cubes was to make a standardized, cracker-like foodstuff which was molecularly simple enough that most carbon-based life forms can digest it.

** Somewhat averted in Season 4, when Crichton's alien companions get to sample earth food. Apparently sugar is a highly-addictive narcotic with crack-like effects on Hynerians. Chiana also tries to eat a tube of lipstick, and justifiably finding it inedible.

** A human in the ExpandedUniverse got sick off alien food designed to resemble earth origin food. Whether this is due to biochemical barriers, or a lack of competence on the aliens' part is unclear.

There are a couple of other cases though, with one of them being of vital plot importance: [[spoiler:the Orphean's "Ovah" is eventually revealed to be a symbiotic virus, and while it's harmless to most species, it does begin getting into some of the native Miran populations, which disturbs the Orpheans greatly; while the plot-important one is the fact that human DNA is extremely toxic to the Ganglion, which as it turns out is the whole reason they wanted to exterminate humanity in the first place.]]

** Mad Cow, more correctly known as Bovine Spongiform Encephalopathy, is a special case as it's not caused by even a rudimentary lifeform such as a virus. BSE is a prion-based disease. Prions are mis-folded proteins that are nonetheless stable enough to interact with a biological system, and several are known to causes diseases. Since proteins are one of the most fundamental building blocks of earth life, it wouldn't be surprising to find prion-based diseases capable of infecting a ''wide'' range of earth lifeforms. BSE itself is known to have variants that can infect cows, horses, sheep and humans.

* A ComicBook/FantasticFour comic 'negative zone' has The Thing and Mr. Fantastic visit an alien space station with an acidic atmosphere. After having his helmet broken it turns out The Thing can breathe the air, it just tastes awful. This is due to his powers however. Another alien has no problem breathing on earth after previously breathing an acidic atmosphere.
* Inverted in ''ComicBook/TheScrameustache''. HumanAliens wear protective gears on earth ''because of our pollution''. But those who spend too much time on Earth adapt.

* Averted in a Creator/NicholasFisk short story. Human spacemen discovered a cute photogenic alien on a hostile unpleasant planet. They took it home, carefully replicating the environment they found it in. Turns out the sentient alien was an explorer, only able to cope with the hostile environment for a short time. As the alien transformed from cute and photogenic to sick and ugly, the humans lost interest and it was able to escape. Turns out earth rain and atmosphere were perfect conditions for recovering. Plus food for the soul in a friendship with a little kid.

* Averted in ''Series/BabylonFive'' in that there are sections of the station sealed off for species that breathe atmospheres other than the oxy-nitrogen standard that seems to be common among the humanoid races. Some of these zones were mild enough that humans could enter them with just respirators, while others (never seen on screen) were apparently nasty enough to require full pressure suits. This difference is mostly informal, since except for the encounter suit-wearing Gaim and Vorlons ([[spoiler:the latter don't actually need them]]) and whatever Na'grath is supposed to be, any alien we see on Babylon 5 is effortlessly capable of surviving in earth-like atmospheric conditions. And a simple set of gill implants seems to enable oxygen-breathing species (or at least humans and Narn) to survive in even the Vorlons' CO2/sulfur/methane atmosphere without any external equipment.
