The safety of skin-on meat obtained from singed carcasses is a matter of public health concern. This study was therefore carried out to investigate the concentration of heavy metals [lead (Pb), cadmium (Cd), zinc (Zn), manganese (Mn) and copper (Cu)], phenol and polycyclic aromatic hydrocarbons (PAH) in red Sokoto buck goat carcasses singed using fire wood, kerosene, scrap tire and liquefied gas (LG). A total of 24 good grade red Sokoto buck goats weighing between 18 and 20 kg were randomly distributed into each of the 4 treatments in a completely randomized design. Each treatment was replicated 6 times. The total PAH and phenol contents were determined by HPLC, whereas the minerals were measured by atomic absorption spectroscopy (AAS). PAH levels were highest (P < 0.05) in scrap tire singed carcasses (0.040 mg/kg) and least in LG singed carcasses (0.001mg/kg). Pb and Mn were below detectable limit in carcasses singed with LG while the concentrations were similar (P > 0.01) in the other treatments. Cd was not detected in any of the treatments. Zn concentration was highest (P > 0.05) in carcasses singed with kerosene (0.005mg/kg). The level of phenol ranged from 0.02 Gae/kg in LG singed carcasses to 0.38 Gae/kg when scrap tire was used. Material used in singeing was found to have profound effect on heavy metal, phenol, and PAH depositions on skin-on meat from red Sokoto buck goats.
