Let me start by saying this one is not for the squeamish.
For years I’ve shared many a foodborne malady. When people think foodborne illness they think tummy flu, Not, toxin megacolon… or sexually transmitted fish toxins, or any of the other bizarre case reports I run across of things one can contract at the dinner table.

It wasn’t the sushi worm found living in someone's stomach, or the swallowed fish bone that came poking out. No, it was Linguatula serrate, tongue worm in human eye.
Evidently if we prefer our viscera poorly cooked we can swallow eggs that hatch within our intestines into worm-like bloodsucking parasites that burrow out through the intestinal wall and then migrate throughout the body. Rarely, they can tunnel into the eye. And when they say tongue worm in human eye, they mean like literally swimming around inside the eyeball, and yes, they've got video:

The one I mentioned about the fish toxins that spread through intercourse is Sexually Transmitted Fish Toxin.
