Abstract
market of Cairo, Giza, Fayoum, Domiate, Dakhalya, Gharbia and Sharkya were determined. Proximate
chemical analysis and microbiological content of the cheese were determined. All samples except
Cairo samples were not conformed with the Egyptian standards chemically and microbiologically.
All samples contained the tested heavy metals especially aluminium, chromium and lead in higher
concentration than the IDF-values. Domiati cheese was manufactured under the industrial
conditions, raw materials, cheese and whey were analysed periodically during pickling over 90 days.
Raw milk contained higher concentration of tested heavy metals than those reported in literature.
Rennet contained high concentration of aluminium and edible salt was highly contaminated with heavy
metals. Over 60% reduction in aluminium, chromium, lead and zinc concentration in cheese were found
after 90 days of pickling. Accordingly, it is recommended to inface strict inspection of raw
materials used in cheese industry especially edible salt to reduce the source of this hazard. Also
it is nesessary to revaluate, the permissible levels of heavy metals in Egyptian food standards in
order to ensure the safety of food consumption.
