Control of konzo in DRC using the wetting method on cassava flour

► The wetting method to remove cyanogens from cassava flour was taught and used by mothers in a village with 34 konzo cases. ► This reduced the cyanogens in flour to safe levels and greatly reduced the urinary thiocyanate content of school children. ► It produced tastier fufu and prevented new cases of konzo over 1.5 years, including two dry seasons when konzo is at a peak. ► Konzo was first identified in 1938 in DRC and has now been prevented for the first time in the same area. ► This methodology is being used in other villages in DRC and we believe it is the way to control konzo in tropical Africa.
