Evaluation of Cadmium (Cd) in Domestic Chicken Meat and Offal and Associated Health Risk Assessment in Ibadan

The study was carried out on the evaluation of cadmium in chicken meat and offal in three markets in Ibadan. The appraisal was aimed at assessing the cadmium that has accumulated in the kidney, liver, intestine, blood, muscle and feathers of chicken widely consumed in domestic chicken (Gallus gallus domesticus). Ten mature chickens were bought and dissected to remove the chicken meat and offal samples. This samples were oven-dried separately and pulverised into powdered form through grinding with a mortar and pestle. These were acid-digested for cadmium analyses using Buck Scientific 210 VGP Atomic Absorption Spectrophotometer. The overall results from all the study sites showed varying mean concentrations in the intestine (0.713 ± 0.024 ppm), feather (0.702 ± 0.035 ppm) and muscle (0.592 ± 0.019 ppm) with low mean concentrations in the blood (0.426 ± 0.032 ppm), liver (0.432 ± 0.021 ppm) and kidney (0.352 ± 0.027 ppm). Most of the chicken meat and offal samples were above the WHO guideline limit of 0.05 ppm. The Target Hazard Quotient (THQ) from the study was below 1 which suggested that the general populace in this study area was not at risk.
