Hazaribagh the area of leather processing industries; is the main place of Bangladesh fromwhere the poultry and fish feed have produced and supplied all over the country. Solid tannery wasteand sliced- cut pieces of skin and hide are proteineceous. These wastes are converted to protein- concentrate to be used in poultry feed, fish feed and bio fertilizer without any appropriate treatment.Although total Chromium content in tannery waste based poultry and fish feed has been determinedpreviously but no studies appear to have been on others heavy metals i.e. Zn, Pb, Cd, Ni, Mn and Fe.AAS is used to determine the heavy metals concentration in ppm. A total three types of samplewere collected from different location of sampling site. The sample represents the various stages ofprotein - concentrate production from solid waste to final products i.e. poultry and fish feed ingredients.All heavy metals were not only detected in all sample type but also significantly higher than the MAC value for poultry and fish feed ingredients and cross the permissible limit for human.
