Frankenfood (after Mary Shelly's character, Frankenstein) is a label of disapproval applied to food products deemed to have been produced by unnatural—and by implication, obscene—means. The term is applied to the use of genetically modified organisms in food production, a common practice in the United States but widely rejected in parts of Europe. "Frankenfood" has become a battle cry of the European side in the US-EU agricultural trade war.
