A woman has experienced one of the absolute worst seafood experiences anyone has ever had, and it's going to haunt you for life. The story came out through a scientific paper from the Journal of Parasitology, where a 63 year old Korean woman experienced severe pain in her mouth after eating a piece of squid. She is said to have "experienced severe pain in her oral cavity immediately after eating a portion of parboiled squid along with its internal organs" because... the internal organs still contained a sperm bag. The bag, you guessed it, popped in her mouth and literally inseminated the woman's mouth and cheek with tens of little wriggly squid goodies. She describes feeling a "pricking and foreign-body sensation" and quickly spat the squid out, but in hospital several "small, squirming, white spindle-shaped, bug-like organisms [were found] stuck in the mucous membrane of the tongue, cheek, and gingiva."
Researchers think that the squid's sperm bags might have popped out while the woman applied pressure by chewing. Daana Staff, from Squid A Day, explained: "Each [squid] spermatophore includes an ejaculatory apparatus, which can expel the sperm mass quite forcefully, and a cement body for attachment. Of course, neither of those is a needle or a knife—the sort of thing you'd expect to need for actual implantation (into either a female squid or a human mouth). I've written a bit about this mystery before. As it turns out, no one is quite sure how spermatophores implant themselves into skin." Yet implant themselves into skin, they do. It's far from the first time a squid has tried to fertilize a human mouth, and there have been several incidents in Japan alone where people have complained of oral stings from their food.
What makes this case a tiny bit different is the fact the squid was parboiled, as usually the bags wouldn't survive in the heat to make it all the way into your unsuspecting mouth. Don't get nervous just yet, because us Westerners should be okay. The way we prepare and cook squid usually means the internal organs are totally removed and its cooked on a high enough heat to kill the spermatophores. Also, in order to be properly dangerous they'd make to make it all the way inside a mucous membrane. You should be save for now.
