Appraisal of Lead In the Organs and Tissues of Domestic Chicken (Gallus Gallus Domesticus) in Ibadan

A study was carried out on the assessment of lead in the organs and tissues of domestic chicken (Gallus gallus domesticus) in Ibadan from August to October 2015. Ten (10) chickens (layers and broilers) expressed as samples 1-10 were purchased from different retailer markets (Bodija, Ojoo and Sango) within Ibadan City. The chickens were dissected to remove the intestine, liver, kidney, blood, feathers and muscles were oven-dried at 220°C. The pulverized organ and tissues samples were aciddigested and analyzed for the heavy metal lead (Pb) using Buck Scientific Atomic Absorption Spectrophotometer (AAS). The results showed that the highest Pb concentrations in parts per million (ppm) were recorded in the liver (2.940 ± 0.040), intestine (3.9800 ± 0.500), kidney (3.6600 ± 0.6000), feather (3.5900 ± 0.06000), and muscle (3.400 ± 0.4000) in sample 10, while the lowest concentration was recorded in the kidney (0.150 ± 0.0300) in sample 1 all at Bodija Market. Analysis of Variance (ANOVA) revealed significance of the Pb metal in the organs and tissues of chickens at P<0.05. Less than half of the samples had Pb concentration that exceeded the permissible limit of 0.1 ppm set by FAO/WHO. The study shows that meat from the chicken organs and tissues in Ibadan are relatively safe for human consumption.
