African cuisine
Tihlo, prepared from roasted barley flour, is very popular in Amhara, Agame, and Awlaelo (Tigray). Traditional Ethiopian cuisine employs no pork or shellfish of any kind, as they are forbidden in the Jewish and Ethiopian Orthodox Christian faiths. It is also very common to eat from the same dish in the center of the table with a group of people.
Harmful algal bloom
Diatoms produce domoic acid, another neurotoxin, which can cause seizures in higher vertebrates and birds as it concentrates up the food chain. Domoic acid readily accumulates in the bodies of shellfish, sardines, and anchovies, which if then eaten by sea lions, otters, cetaceans, birds or people, can affect the nervous system causing serious injury or death. In the summer of 2015, the state governments closed important shellfish fisheries in Washington, Oregon and California because of high concentrations of domoic acid in shellfish.
