Eating raw meat is always a risk. You are putting your health in the hands of the chef and kitchen staff who must make sure everything is as fresh as can be and meat that can spoil is prepared right and stored properly. Here is a news story about a restaurant that apparently forgot to make sure the squid they were serving was, well, dead.
So, I guess they erred on the fresh side, which you have to give them props for. But nonetheless, I was shocked to learn that a squid can implant its sperm bag, whatever that is, in your mouth. I really don’t need to know one single other thing about it to say let’s go ahead and just ban it.
