Authorities closed 16 cooking oil factories in the Ethiopian capital Addis Ababa on Tuesday after eight people were killed and scores sickened by food cooked with contaminated oil.
In a statement, the Health Ministry said 94 people were in hospital with suspected poisoning, and urged the public to only buy cooking oil marked with government safety stamps.
"Study indicated that a highly toxic oily fruit, unfit for human consumption, had been mixed with other ingredients by the factories processing edible oil,"the statement said.
