Abstract
A study was carried out on the appraisal of lead and cadmium in the caprines of goats in Ibadan, Nigeria between June and September 2016. Caprines from six goats were collected from Bodija market in Ibadan. A total of 36 samples (Liver, lungs, oesophagus, intestines, heart and muscle) were used in the study. The samples were ashed in a furnace at a temperature of 400°C for two hours for each batch and stored in sample bottles prior to acid digestion. The heavy metals lead (Pb) and cadmium (Cd) were then analyzed using Buck Scientific Atomic Absorption Spectrophotometer (AAS). Each analysis was done in triplicates while standard and blank samples were analyzed for all the 36 samples. The results showed that the highest Cd concentration was found in the liver (0.06ppm) in sample 5 and in the heart of sample 6 (0.06ppm) which exceeded the WHO guideline limit of 0.05ppm. The highest concentration of Pb was found in the heart of sample 1 (0.63ppm), the liver of sample 2 (0.42ppm), the lungs of sample 3 (0.83ppm) and the liver of sample 4 (0.33ppm) all of which exceeded the WHO set limit of 0.01ppm. The study showed that the consumption of caprines and meat (muscle) from goats slaughtered in in Ibadan is relatively safe. It is therefore recommended that there should be regular biomonitoring of heavy metals in the caprines and meat from livestock slaughtered in Ibadan, Nigeria for public health safety.
