Abstract
The study was conducted to determine absorption of essential and non- essential trace minerals from poultry feed to poultry products. Poultry feed, liver, muscles and egg samples were collected from six poultry farms of Rawalpindi and Islamabad. Mercury, Lead, Cadmium, Chromium and Iron were analysed in the samples using Inductively Coupled Plasma Optical Emission Spectrophotometer. Iron, Lead and Chromium exceeded the permissible limits set by World Health Organization and National Research Council in Poultry feed. Lead was high in liver, breast muscles, thigh muscles, egg albumen and egg yolk. Chromium was found in feed, egg yolk, egg albumen and two (02) of the liver and breast muscle samples. Mercury was not detected in any of the samples. Liver contains significantly higher concentration of detected heavy metals as compared to thigh and breast muscles and egg yolk contained significantly high concentrations of Iron, Cadmium and Lead as compared to egg albumen. Standards requirements for feed manufacturers and poultry farmers should be maintained to monitor and mitigate routes of entry of contaminants in the food chain.
