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.
Oilfish
Oilfish is pleasantly rich in taste and can be substantially cheaper than some other fish species, leading to some fish sellers intentionally mislabelling it as butterfish or even codfish, despite the utter lack of relation. This leads the consumer to often eat large servings, as they assume it is a fish with which they are familiar, and then some may experience a laxative effect. Because of this, Japan and Italy have imposed an import ban on oilfish. Australia does not ban oilfish from being sold but recommends retailers and caterers to inform consumers about the potential risk associated with oilfish consumption. The US FDA has warned consumers about potential mislabeling of oilfish, but has concluded any laxative side effects that occur are uncomfortable at worst and pose no health risk. Escolar, a relative of oilfish, also has high concentrations of wax esters and is mislabeled similarly.
