Heavy metal contamination and health risk assessment of mechanically milled delicacy called fufu
Abstract Contamination of food by heavy metals is a concern as consumption of contaminated food is one of the most likely human exposure routes to metals. Fufu is a delicacy in Ghana consumed mainly by the Akans. Human exposure to some heavy metals (Cr, Fe, Zn, Mn and Ni) through mechanically proces...

| Sumario: | Abstract Contamination of food by heavy metals is a concern as consumption of contaminated food is one of the most likely human exposure routes to metals. Fufu is a delicacy in Ghana consumed mainly by the Akans. Human exposure to some heavy metals (Cr, Fe, Zn, Mn and Ni) through mechanically processed fufu consumption was analysed by atomic absorption spectrophotometer and ascertaining consumer awareness of potential exposure by questionnaire administration. A total of 30 milled and un-milled fufu samples (cassava and plantain) were sampled from Bomso, Kotei, Ayeduase, Ayigya and Kentikrono, all within Kumasi. The results showed that Fe and Zn levels after milling were elevated in the range: 2.816–7.297 and 0.753–7.529 mg/kg, respectively. The concentrations of Fe and Zn were below the Food and Agriculture Organization/World Health Organization (FAO/WHO) permissible limits except Zn concentration at Bomso. Cr, Mn and Ni were below the detection limit (0.05). Hazard quotients and indices were less than the US Environmental Protection Agency’s permitted level of one, indicating no possible harm to consumers. Findings from the questionnaire administration indicated a complete lack of knowledge on consumer exposure due to the food processing method. |
