Concerns over food safety have renewed attention on cassava, one of Nigeria's most widely consumed staple crops, following warnings from agricultural experts that improperly processed cassava can pose serious health risks.
Experts say cassava naturally contains cyanogenic compounds that can release cyanide, with the levels varying depending on the variety of cassava and how it is processed.
Cassava is commonly classified as sweet or bitter cassava, with bitter varieties generally containing higher levels of cyanogenic compounds.
However, experts stress that the risk does not depend solely on the type of cassava consumed.
Processing methods—including fermentation, drying and proper storage—can play an important role in reducing potential hazards before cassava products reach consumers.
Agricultural specialists also warn that unsafe handling practices or the inappropriate addition of substances during processing could create additional risks.
The concerns have therefore shifted attention from what consumers eventually eat to the entire chain through which food moves—from the farm and processing facilities to vendors and the family kitchen.
Experts say food safety must be treated as a shared responsibility.
Farmers need to produce and harvest crops safely, processors must follow appropriate procedures, vendors must maintain hygienic conditions, regulators must enforce standards and consumers must exercise caution when purchasing and preparing food.
For consumers, experts recommend paying attention to where food comes from rather than simply choosing the cheapest available option.
They also stress the importance of proper hygiene when handling food, including keeping hands and preparation surfaces clean, protecting food from flies and other pests, and storing food in appropriate environments.
The warning comes against the backdrop of concerns about foodborne illnesses in Nigerian communities.
Experts say the consequences of unsafe food can extend beyond individual households, placing additional pressure on hospitals, reducing productivity and, in severe cases, resulting in loss of life.
They argue that prevention should begin long before a patient reaches a hospital.
The circumstances surrounding the reported deaths of members of the Okwuwekwe and Ehima families have therefore brought renewed attention to the importance of food safety practices.
While investigations are necessary to establish the precise cause of any suspected food poisoning incident, experts say the wider lesson is that ordinary food can become dangerous when critical safety procedures fail.
They are calling for stronger public education and closer monitoring of food processing and distribution practices.
The message is clear: food safety does not begin at the dining table or in the hospital. It begins at the farm and continues through every stage of the journey to the consumer.
