Can I eat casu marzu pizza?
Quick Answer
Yes, but with caution
Casu marzu is a traditional Sardinian cheese that contains live insect larvae. While it’s considered a delicacy in some regions, it can pose health risks if not consumed properly.

What Is It?
Casu marzu is a traditional Sardinian cheese that’s intentionally infested with the larvae of the cheese fly. The larvae help to break down the cheese’s fats, resulting in a very soft, creamy texture. It’s often spread on flatbread or used as a topping for pizza.
Historical Context
Casu marzu has been a part of Sardinian culture for centuries. It’s traditionally made from sheep’s milk and is considered a delicacy, often served at special occasions.
Why It Can Be Risky
While casu marzu is enjoyed by many, it does come with some potential health risks.
- The larvae in the cheese can survive in the human stomach and cause an infection known as pseudomyiasis.
- The cheese is often consumed when the maggots are still alive. If they are accidentally ingested, they can potentially burrow into the intestines, causing severe abdominal pain.
Safe Method?
To safely consume casu marzu, it’s recommended to remove the larvae before eating. Some people also prefer to chill the cheese in the refrigerator before consumption, which can cause the larvae to become dormant and easier to remove.
Safe Alternatives
If you’re not comfortable with the idea of eating casu marzu, there are many other types of Sardinian cheese that you might enjoy, such as pecorino sardo or fiore sardo.
Storage Tips
Casu marzu should be stored in a cool, dry place. It’s also important to keep it covered to prevent additional flies from laying eggs in the cheese.
Legal Considerations
In some countries, including the United States, casu marzu is considered illegal due to health concerns. Be sure to check the laws in your area before attempting to purchase or consume this cheese.
