It is known as the world's most dangerous cheese. Yeah, you heard right. (mellow music) Meet Simone Ibba, a third generation sheep farmer. - [Narrator] Casu marzu literally means rotten cheese, and it's not for the faint of heart, because this cheese is infested with thousands of live maggots. And while that might seem a bit off-putting at first, it's the maggots that give the cheese its distinctive texture and flavor. Here's how it works. First, a traditional wheel of pecorino cheese is made from sheep's milk. Then a special fly called a cheese fly is allowed to lay its eggs in it. - [Narrator] Over the course of two to three months, the maggots eat the cheese, and then excrete it out again, transforming it into the soft and creamy casu marzu. - [Narrator] Today, it's a favorite for special occasions, like weddings and birthday parties. But eating this cheese can be dangerous. - [Narrator] Even though cases like this are extremely rare, it's risky enough that the cheese is illegal to sell. But farmers like Simone continue to make it for themselves. - [Narrator] And they just can't get enough.
