In a stark warning that could change how Nigerians process their staple foods, the Federal Institute of Industrial Research, Oshodi (FIIRO), has labeled the common use of locally made grinding machines as a major health hazard lurking in kitchens across the country.
These machines, often seen whirring away in markets and homes grinding peppers, corn, beans, and other essentials, might be doing more harm than good. According to FIIRO experts, the issue boils down to the materials used in their construction. Most local fabricators opt for cheap unalloyed cast iron or even scrap metals, skipping the recommended food-grade stainless steel that's designed to handle food safely.
The problem? These substandard materials are prone to quick corrosion and breakdown. During the intense grinding process, the friction between the machine's plates causes rapid wear and tear. As a result, tiny particles of iron and dangerous heavy metals – including lead, chromium, and cadmium – flake off and contaminate the food directly.
Unlike the natural components in our meals, our bodies can't break down or eliminate these metallic intruders easily. Over time, they build up in key organs, setting the stage for serious health issues. The kidneys, which work as the body's natural filter, bear the brunt first, leading to conditions like nephropathy and, in severe cases, complete kidney failure.
The liver isn't spared either. As it tries to store and process these toxins, inflammation kicks in, causing cell damage and hepatotoxicity – a fancy term for liver poisoning. And it doesn't stop there: elevated heavy metal levels in the blood have been directly linked to high blood pressure and a range of heart-related diseases, turning everyday meals into a slow-building threat.
FIIRO's call to action is clear and urgent: it's time for Nigerians to ditch these risky cast-iron setups. The institute strongly recommends switching to machines built with food-grade stainless steel, which resists corrosion and keeps toxic particles out of your food entirely.
Health officials at FIIRO emphasize that this isn't just about fancy equipment – it's about protecting families from preventable dangers. "We've seen the data, and the risks are real," a FIIRO spokesperson told ReportNaija. "Making the switch could save lives in the long run."
As awareness spreads, market vendors and households are encouraged to inspect their grinding tools and demand better standards from fabricators. For now, that familiar hum of the local grinder might just be a warning sign in disguise.
