“This often happens during times of famine and war. Cyanide in cassava is associated with acute cyanide poisoning and several diseases, including konzo.
“Konzo is an irreversible spastic paraparesis of sudden onset, associated with the consumption of bitter cassava and a low protein intake. It is a disease of extreme poverty. Konzo mostly occurs in epidemics, but sporadic cases are also reported.”
Safe Consumption of Cassava
Although cassava has a dangerous reputation, millions of people eat it safely every day. The key lies in proper preparation to eliminate its toxins.
To make cassava safe to eat, it must be processed correctly—soaking the plant for up to 24 hours is one of the most effective methods to remove harmful substances.
In times of food shortages, the risks increase. For example, during Venezuela’s food crisis in 2017, some people tragically lost their lives after eating bitter cassava out of desperation.
Despite its risks, cassava remains an essential food source for millions. With the right preparation, it can continue to sustain populations without posing a deadly threat.
