The Federal Institute of Industrial Research, Oshodi (FIIRO) has raised concerns over the possible health implications of foods processed with locally fabricated grinding machines.
In a statement issued to journalists in Lagos, the Director-General of the institute, Dr. Jummai Adamu Tutuwa, revealed that research findings by FIIRO scientists linked certain grinding machines commonly used in markets to the presence of harmful substances in food.
According to her, a comprehensive assessment conducted in 2013 showed that some locally produced grinding machines used for processing tomatoes, pepper, onions, melon seeds and other food items, particularly within the Lagos metropolis, contained traces of heavy metals.
These include lead, copper, chromium, nickel, cadmium and manganese. Non-heavy metals such as calcium, magnesium, zinc and iron were also detected.
Dr. Tutuwa explained that regular consumption of food contaminated with heavy metals could increase the risk of cardiovascular diseases and organ failure, even among younger individuals.
She added that in certain locations, especially high-traffic and industrial areas, contamination levels were found to exceed safety limits set by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO).
She noted that although heavy metals occur naturally in the environment, they become dangerous when they accumulate in the body over time, as they do not easily degrade and can build up along the food chain.
Cadmium, in particular, was described as a major concern due to its extensive industrial applications and toxic effects.
As part of efforts to tackle the problem, the institute has developed a stainless-steel pepper grinding machine aimed at reducing contamination.
FIIRO also plans to work closely with the National Assembly, the Office of the First Lady and other relevant stakeholders to encourage the large-scale production, distribution and proper monitoring of safer alternatives.
The institute emphasized the need for stricter regulation, effective enforcement and increased public awareness to minimize food contamination and help reduce the growing cases of cancer, cardiovascular diseases and organ failure across the country.
