The Federal Institute of Industrial Research, Oshodi (FIIRO) in Lagos has raised concerns that the growing cases of organ failure and cardiovascular diseases in Nigeria may be connected to foods processed with locally fabricated grinding machines.
Dr. Jummai Adamu Tutuwa, Director-General of FIIRO, revealed this in a statement citing the institute’s research. She explained that a detailed assessment conducted by FIIRO scientists in 2013 found that locally made grinders—commonly used for tomatoes, peppers, onions, melon seeds, and other staples—contained traces of heavy metals such as lead, copper, chromium, nickel, cadmium, and manganese. Non-heavy metals like calcium, magnesium, zinc, and iron were also detected.
According to Dr. Tutuwa, long-term consumption of food contaminated with these metals could be a factor behind the increasing rates of cardiovascular diseases and organ failure, even among young adults. In some cases, contamination levels exceeded safety limits set by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO), particularly in areas with heavy traffic and industrial activity.
She highlighted that while some heavy metals occur naturally, their bioaccumulation, persistence, and high concentrations in the food chain make them dangerous to human health. Cadmium, in particular, was described as a serious environmental concern due to its widespread industrial use.
To tackle the problem, FIIRO has developed a stainless-steel pepper grinding machine aimed at minimizing contamination risks. The institute also plans to work with the National Assembly, the Office of the First Lady, and other stakeholders to promote safer alternatives through large-scale production, distribution, monitoring, and maintenance.
Dr. Tutuwa emphasized the need for stronger regulation, effective enforcement, and increased public awareness to reduce exposure to contaminants and lower the prevalence of cancer, cardiovascular diseases, and organ failure across the country.
