Konzo is an irreversible neurological disease of sudden onset with permanent partial paralysis in the legs, caused by consumption of poorly processed cassava that has high levels of cyanide. This project will train mothers to use a cassava processing wetting method (WTM) to remove the cyanide from the cassava flour before it is eaten. WTM training will be embedded within Early Childhood Development (ECD) caregiver training to better motivate the use of the WTM, saving children's brains from cyanide while providing mothers with practical strategies for stimulating cognitive/physical development.
