description Casu Marzu Overview
Casu marzu is a traditional Sardinian sheep's-milk cheese whose ripening involves the cheese fly Piophila casei; the larvae digest the cheese and produce a soft, decomposed texture. The cheese is made from a pecorino-type base and is recognized as a distinctive part of Sardinian food culture. It is generally not authorized for commercial sale in the European Union under food-safety rules, while Italian authorities prohibit placing it on the Italian market.
