Abstract

This research aims to investigate the presence of cyanide in commercial garri sold in major markets in Ibadan metropolis. Two hundred (200) garri sample were collected from about ten (10) LGAs within Ibadan Metropolis and their environs. The higher concentration of HCN acid was 0.00097±3.77mg/kg from Oja-oba market in Ibadan south-west LGA while the lowest concentration of 0.00067±2.88mg/kg was detected from sample still from Oja-oba market in Ibadan south-west LGA. High concentration of HCN acid 0.00095±3.3mg/kg was detected from Olomi market in Ibadan north-east LGA, same concentration 0.00096±3.31mg/kg also detected from sample from Apata market in Ibadan south-east LGA. HCN acid concentration of 0.00095±2.88mg/kg was detected from garri sample from Apata market, Oje market, Mokola market, Bodija market and Beere market. High concentration of HCN acid i.e 0.00094±8.25mg/kg was found in samples from Mokola market and Beere market in Ibadan north LGA. High concentrations of 0.00093±5.22mg/kg was detected in garri samples from Oje market, Dugbe market, Olomi market, Sasa market, Omii market, Aleshinloye market, Iwo road market, Bodija market, Gbaji market, Bashorun market and Beere market in Ibadan south west LGA. HCN acid concentration of 0.00092±4.5mg/kg was detected in garri sample from Bode market, Olomi market, Oke-Ado market, Molete market, Gbaremu market, Aleshinloye market, and Beere market. The HCN acid concentration in all the two hundred (200) garri samples were below 10mg/kg, the Maximum Permissible Level (MPL) recommended by WHO/FAO (2012), USEPA (2013) and EU (2015). Therefore, the entire sample investigated were recommended for public consumption.
