Toxic cassava from old gold mines threatens Ghana’s food safety
A new study has revealed alarming levels of cyanide and lead in cassava grown on former gold mining lands. The research focused on two communities in Ghana’s Eastern Region—Pameng and Gyadam—where illegal mining has left behind toxic residues. These findings raise concerns about food safety and long-term health risks for local residents.
Illegal gold mining, known locally as galamsey, has polluted water sources and soil in the Eastern Region. When miners abandon sites, the land is often repurposed for farming without proper cleanup. Cassava, a staple crop in the area, absorbs dangerous metals from the contaminated soil.
Tests showed that while cassava from these reclaimed sites contained high nutrient levels, it was also laced with cyanide. Consuming such crops can lead to severe health problems, including cancer, anaemia, paralysis, and mental health disorders. Infants are especially at risk due to their developing immune systems. No specific organisation has been publicly named as responsible for tackling illegal mining or reclaiming contaminated land. Reports from bodies like the UNODC highlight the global issue of minerals crime, while initiatives such as Peru’s Operation Quecksilber demonstrate efforts to secure and restore affected areas.
The study underscores the urgent need for soil testing and safer farming practices in former mining zones. Without intervention, contaminated crops will continue to pose health threats to communities. Authorities have yet to announce concrete measures to address the problem.
