This is the infamous casu marzu cheese. It’s a cheese with quite the reputation, and I am here to tell the tale of my time with it.
Casu marzu is a traditional Sardinian cheese most notable for its extreme fermentation due to the presence of the larvae of Piophila casei, a cheese fly. The cheese starts out as a pecorino but turns into something quite different, thanks to this fly. It lays its eggs and the larvae go to town on it, digesting the cheese and breaking down its fat.
The worms are apparently unhappy when disturbed, and it’s reported that they can launch themselves up to 6 inches, presumably in the direction of the person who is doing the disturbing.Thankfully, I did not encounter any of these creatures. My friend kept looking for the worm but it was nowhere to be seen. However, I am still alive, so the cheese wasn’t toxic; the little worms were just hiding.
