🧀 Casu Marzu
Casu Marzu is a traditional sheep’s milk cheese from Sardinia that is famous (and controversial) because it contains live insect larvae.
What Is It?
Casu Marzu means “rotten cheese” in Sardinian. It starts as Pecorino Sardo, a firm sheep’s milk cheese, but it’s deliberately exposed to the cheese fly (Piophila casei). The flies lay eggs in the cheese, and when the larvae hatch, they:
- Eat through the cheese
- Break down the fats
- Create an extremely soft, creamy texture
By the time it’s ready, parts of the cheese are almost spreadable and may even ooze.
Why Is It Controversial?
- The cheese contains live maggots when eaten.
- The larvae can jump when disturbed (sometimes several inches).
- Due to health regulations, it has been banned from commercial sale in Italy and the EU, though it is still made and consumed locally.
How Is It Eaten?
Traditionally:
- Served on thin Sardinian flatbread (pane carasau)
- Paired with strong red wine (often Cannonau)
- Some people remove the larvae before eating; others eat it with them
Safety Concerns
There have been concerns about:
- Food safety regulations
- Potential intestinal issues if larvae survive digestion
However, locals consider properly prepared Casu Marzu safe to eat.
Cultural Importance
Despite legal issues, Casu Marzu is seen in Sardinia as:
- A heritage food
- A symbol of rural tradition
- Sometimes served at weddings and special occasions
It has even been listed by Guinness World Records as the “world’s most dangerous cheese.”
If you’d like, I can also compare it to other unusual cheeses around the world.
