Preventing Paralysis:
A Scientific Mission to Make Cassava Safe for Millions


Cassava stands as a cornerstone staple food across sub-Saharan Africa, sustaining millions of families daily. Yet this vital crop harbors a deadly secret when improperly processed: cyanogenic glycosides that release toxic cyanide, causing acute poisoning, chronic toxicity, and konzo – a devastating form of paralysis predominantly affecting children. Professor Obadina, a lecturer and researcher at the Federal University of Agriculture in Abeokuta, Nigeria, has dedicated two decades to addressing this public health crisis through rigorous scientific research and community-based interventions that could save thousands of lives across the continent.

The Hidden Danger in Africa’s Food Supply

Cassava exists in two primary varieties: bitter cassava with high cyanogenic glycoside concentrations, and sweet cassava with lower levels. Nigeria has largely overcome cassava toxicity challenges through proper processing methods – including thorough peeling, fermentation, and heat application – combined with cultivation of safer varieties. However, neighboring countries face catastrophic consequences. The Democratic Republic of Congo has recorded between 5,000 and 10,000 konzo cases across multiple outbreaks since the 1980s and 1990s, with thousands of children suffering permanent paralysis. Mozambique and Tanzania have reported sporadic cases linked to drought periods and conflicts when desperate populations rely on inadequately processed cassava.

The correlation between food security and food safety creates a vicious cycle: during scarcity, people cannot afford the time required for proper processing methods that remove toxins. Symptoms may appear weeks after consumption, obscuring the connection between cassava and illness. Many affected families never seek hospital treatment, relying instead on traditional remedies, which means official data drastically underrepresents the true scale of suffering. Professor Obadina emphasizes that effective policy formation requires robust data—precisely what Africa’s public health systems lack.


A Multi-Phase Strategy for Sustainable Change

Professor Obadina’s Safe Cassava Project employs a comprehensive, data-driven approach spanning four critical phases.

Phase 1

Research and Development

$15,000 – $20,000

Establishes baseline data across previously identified high-risk countries, categorizing cases by age and geographic location. This phase leverages a breakthrough methodology developed with Dutch colleagues: using cassava leaf enzymes (linamarase) to rapidly break down cyanogenic glycosides and release cyanide from cassava roots. Laboratory and field experiments have validated this technique’s effectiveness.

Phase 2

Farmer Training and Capacity Building

$10,000 – $15,000

Educates farmers on safe processing techniques through manuals, videos, in-person workshops, field demonstrations, and monitoring systems. Since farmers primarily process cassava products, their knowledge directly determines community safety.

Phase 3

Processing Technology and Equipment

$35,000 – $40,000

Equips farmer cooperatives with essential machinery – grating machines, pressing equipment, and drying systems – while establishing processing centers in high-need regions identified through baseline surveys.

Phase 4

Public Health and Awareness Campaigns

$5,000 – $6,500

Raises consumer awareness about processing dangers through radio, television, social media, community outreach, and partnerships with local health organizations.

This holistic approach addresses technical, educational, and cultural dimensions simultaneously.


The project incorporates postgraduate students throughout phases, providing stipends and tuition support while building Africa’s next generation of food safety researchers. All donors – whether individuals or corporations aligning with social responsibility mandates – receive direct progress updates, creating transparent accountability between supporters and ground-level implementers. Professor Obadina’s work represents more than research; it offers tangible pathways to preventing preventable tragedies while enhancing nutritional quality and productivity of this essential crop.
