Ethiopian cuisine
Both Ethiopian Orthodox Christians and Muslims avoid eating pork or shellfish, for religious reasons. Pork is considered to be unclean in both Ethiopian Orthodox Christianity and Islam. Many Ethiopians would abstain from eating certain meats, and would mostly eat vegetarian and vegan foods.
Billfish
Billfish are primarily marketed in Japan, where they are eaten raw as sashimi. They are marketed fresh, frozen, canned, cooked and smoked. It is not usually a good idea to fry billfish. Swordfish and marlin are best grilled or broiled, or eaten raw as in sashimi. Sailfish and spearfish are somewhat tough and are better cooked over charcoal or smoked.
