Abstract
The aim of this research was to determine tannins and trace metals level namely; cadmium, cobalt, iron, nickel, lead and tannins in poultry feed sold in Calabar and assess the health risk associated with the consumption of poultry products in the area. To achieve this, two major Brands of poultry feed sold in the area were purchased from the market and taken to the University of Calabar Chemistry Laboratory, labelled, digested and analysed for trace metals using Atomic Absorption Spectrometer and tannins using UV- Spectrometer. The results showed that the poultry feed used in Calabar contains some level of trace metals and tannins with mean values in mg/kg ranging between the two brands thus: Cd (0.25 - 0.39), Co (0.21- 0.37), Fe (6.20 -7.60), Ni (0.25 – 0.32), Pb (0.22 – 0.35) and Tannins (0.35 – 0.64 mg/L). The mean values of the metals in all the feed samples were below the WHO permissible limit of 1mg/kg, except for Fe. There was no significant difference between the amount of trace metals in the two Brands of poultry feed at P<0.05. From the Target Hazard Quotients values of highly less than 1, there is no health risk associated with the consumption of poultry products at the moment
