Ugandans Raise Concerns Over Metal Contamination in Milled Foods

Consumers in Uganda are expressing worries about potential metal particle contamination in commonly consumed milled foods like posho and groundnut paste. Concerns stem from the use of worn-out or poorly maintained milling machinery that may shed metal fragments into the products.

There is growing concern among Ugandan consumers regarding the safety of food products processed by milling machines, particularly those for grinding maize and groundnuts. A significant worry is that worn-out or poorly maintained milling equipment could be shedding tiny metal particles into the food, posing a potential health risk.

During a recent Uganda National Bureau of Standards (UNBS) sensitisation meeting, a resident from Kaliro District highlighted these fears, questioning the regular inspection of milling machines and consumer protection against contamination. He noted a shift from safer rubber rollers to metal components in some mills, which could lead to metal fragments entering the food supply as they wear down.

Observations at a groundnut mill in Jinja City revealed poor hygiene, aging equipment, and a lack of magnetic filters designed to trap metal fragments. While some areas like Kazimingi in Jinja have seen improvements following UNBS intervention, with millers now equipped with magnetic devices, the overall situation requires continued vigilance.

Larger companies like Kakira Sugar Works stated they adhere to international food safety standards, employing metal detection systems. However, UNBS officials acknowledge that some newer manufacturers may not be adequately implementing such measures. UNBS emphasizes that manufacturers must regularly test their metal-trapping systems and employ quality control personnel. The bureau conducts market surveillance and takes action against non-compliant factories.

UNBS encourages manufacturers and millers to comply with safety standards and urges consumers to purchase certified products and report any suspected violations. The US Food and Drug Administration also recognizes metal fragments as a food safety hazard, recommending regular inspections and appropriate detection measures.
