Cassava
Warning: Free hydrocyanic acid will be precipitated after hydrolysis of cassava due to the presence of linamarin in cassava, leading to asphyxia and poisoning of human tissues and cells. Therefore, fresh cassava should not be eaten before cooking, and only suitable varieties can be eaten after detoxification.
