Abstract
The present study was conducted on 40 random samples of raw cow’s and Kareish cheese (20 of each) collected from different farms, individual farmers and dairy shops in Fakous, San El Hagar, kafer saker, and Bilbeis El-Sharkia Governorate, Egypt at the period from October 2018 to January 2019 to determine heavy metal (Pb and Cd) and trace element residues (Cu and Zn) by using Atomic Absorption Spectrophotometer as well as detection of antibiotic residues (penicillin and tetracycline) by using agar well diffusion assay for qualitative detection and High-Performance Liquid chromatography (HPLC) for quantitative detection. Moreover, studying the possibility of removal of heavy metals residues (lead and cadmium) from raw milk by using chelating resin and evaluating the effect of treated milk by chelating resin on laboratory manufactured white soft cheese and yoghurt.
All raw cow’s milk and Kareish cheese samples were contaminated with heavy metal and trace elements in various levels. These are mainly due to the high contamination of animal feed and water by such pollutants and could be excreted into milk and may be reached to milk through handling procedures.
