A lecturer and fish scientist at the University of Ghana has raised serious concerns about the safety of fish consumption in Ghana, particularly tilapia, due to the devastating impact of illegal mining activities (galamsey).
Speaking on Max TV’s Morning Show, Max Morning Live with hosts Franky 5 and Akosua Takyiwaa, Dr. Andrews Agyekumhene of the University of Ghana’s Department of Marine and Fisheries Sciences highlighted the growing public health threat linked to mercury and other toxic chemicals used by galamsey operators.
According to Dr. Agyekumhene, research findings indicate that these harmful substances have contaminated major water bodies, severely affecting aquatic life and, by extension, human health. He described the ripple effects of galamsey as “deeply devastating,” noting that livelihoods dependent on fishing are under threat, while consumers face increasing health risks.
He explained that mercury accumulates significantly in certain parts of fish, particularly the skin, head, and brain tissues, making consumption increasingly dangerous. Tilapia, a staple protein source for many Ghanaian households, was singled out as especially vulnerable due to its habitat and feeding patterns.
Dr. Agyekumhene further referenced reports from health experts, including cases recorded at Korle Bu Teaching Hospital, which indicate a rise in kidney-related illnesses, even among children. These conditions, he noted, are increasingly being linked to prolonged exposure to mercury and other toxic substances through contaminated food sources.
He called for urgent national attention, stronger environmental protection measures, and intensified public education to prevent a looming public health crisis.
