Sannakji: Raw Korean baby octopus
Sannakji is a raw octopus dish meant to be eaten while it's still squirming. The danger here is that despite the sushi chef killing the octopus before serving it, nerve activity allows it to still wriggle, meaning that their suction cups could attach to your throat as you swallow. According to Food & Wine, six people die every year on average from choking on it.
