Cassava roots naturally contain cyanogenic glycosides that can release toxic hydrogen cyanide if not properly processed or detoxified.
The claim is a well-established toxicological fact concerning cassava roots, which contain cyanogenic glycosides that necessitate processing (such as soaking, drying, or fermenting) to prevent cyanide poisoning. Papers 9 and 11 support this by detailing the presence and toxicity of cyanogenic glycosides in plants like cassava and the necessity of food processing for safety.
