Creutzfeldt-Jakob Disease. Possible transmission to humans by consumption of wild animal brains.

Although the natural mode of spread of the agent responsible for Creutzfeldt-Jakob disease is unknown, several reports suggest oral transmission through consumption of contaminated food or brain. This report summarizes four cases of Creutzfeldt-Jakob disease in which a history of eating the brains of wild goat or squirrel was obtained. These cases support the hypothesis of possible acquisition of Creutzfeldt-Jakob disease by ingestion of the agent from a presumptive reservoir in the central nervous system of wild animals.
