I don't understand why the food in the video is moving. And it looks disgusting; even if it wasn't moving I wouldn't want to eat it.
Casu Marzu - WikipediaCasu marzu is considered toxic when the maggots in the cheese have died. Because of this, only cheese in which the maggots are still alive is eaten. When the cheese has fermented enough, it is cut into thin strips and spread on moistened Sardinian flatbread (pane carasau), to be served with a strong red wine. Casu marzu is believed to be an aphrodisiac by local Sardinians. Because the larvae in the cheese can launch themselves for distances up to 15 centimetres (6 in) when disturbed, diners hold their hands above the sandwich to prevent the maggots from leaping into their eyes. Those who do not wish to eat live maggots place the cheese in a sealed paper bag. The maggots, starved for oxygen, writhe and jump in the bag, creating a "pitter-patter" sound. When the sounds subside, the maggots are dead and the cheese can be eaten.
Several food safety issues have been raised in relation to Casu marzu, including anecdotal reports of allergic reactions and the danger of consuming cheese that has advanced to a toxic state. In addition, there is some risk of enteric myaisis, or intestinal larval infection. Symptoms include nausea, vomiting, abdominal pain, and bloody diarrhea. Piophila casei larvae are very resistant to human stomach acid and can pass through the stomach alive, taking up residency for some period of time in the intestines and causing stomach lesions and other gastrointestinal problems. The larvae have powerful mouthhooks which can lacerate stomach linings or intestinal walls as the maggots attempt to bore through internal organs.
The government of Sardinia has outlawed the cheese for health reasons, and offenders may face heavy fines. However, it is possible to get Casu marzu on the black market, where it can sell for double the price of a regular block of Pecorino.
That's absolutely vile, although I love the bit about putting them in a paper bag and hearing them jump out
