Evaluation of heavy metals, phenol and polycyclic aromatic hydrocarbons on singed skin-on red Sokoto buck goats
The safety of skin-on meat obtained from singed carcasses need to be assessed. This study was therefore carried out to investigate the concentration of heavy metals (Pb, Cd, Zn, Mn and Cu), phenol and polycyclic aromatic hydrocarbons (PAH) in red Sokoto buck goat carcasses singed using fire wood, kerosene, scrap tyre and liquefied gas (LG). A total of twenty four good grade red Sokoto buck goats weighing between 18-20kg were randomly distributed into each of the four treatments in a completely randomized design. Each treatment was replicated six times. PAH levels were highest in scrap tyre singed carcasses (0.040mg/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 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 tyre 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.
