I’m pretty sure there’s cases where a whole group of people are wiped out because foreigners brought new diseases in— couldn’t that happen here? With the food especially.
Well we've seen Lulu eating human food, so we know that life on Earth and on her planet has the similar building blocks and molecular chirality. And since she can live comfortably, the environmental conditions of the two places probably aren't that different. This means that alien microbes can potentially sustain themselves on organic products from Ten's body.
But just having the same building blocks doesn't mean that they're the same (a jellyfish and a human also have the same building blocks), and whether microbes can survive in or adapt to a different microbiome is not known, as well as whether the toxins that affect humans could work on Lulu and vice versa. Cross species microbial infection between different distantly-related animals on Earth that don't interact with each other is already relatively uncommon (and cross-kingdom infections are even rarer), so the chances that Ten would get an alien disease is astronomically small.
