Casu Marzu (Italy) More live food, this time from Sardinia in Italy. Casu Marzu is a cheese made with fly larvae, or maggots, to promote a level of fermentation that is close to decomposition. It is traditionally served with live insect larvae still inside. The tiny, translucent worms can jump 15 cm. if disturbed, so many people prefer to bush them off before trying the smelly cheese.
