Abstract: |
Cheese represents an important source of essential amino acids, vitamins, and
trace elements such as copper (Cu), and zinc (Zn). Cheese can be contaminated with toxic
heavy metals due to the use of contaminated ingredients, or during the manufacture
process, and distribution. This study was taken to estimate the residual contents of some
toxic metals including lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg), and trace
elements such as zinc (Zn) and copper (Cu) in five of the most consumed cheese types in
Egypt including Domiati, Feta, Karish, Mish, and Rumi. Moreover, calculation of the
dietary intakes, and health risk assessment among children and adults were conducted. The
obtained results revealed that Mish cheese had the highest residual content of Pb, and As.
Karish cheese had the highest content of Cd, and Zn. Mercury was not detected in Feta and
Domiati cheese. Calculation of the estimated daily intakes, hazard ratio, and hazard index
revealed that consumption of cheese among Egyptian adults and children would not pose
health risks. However, such data should be handled carefully as consumption of cheese
will provide considerable concentrations of the total buildup of heavy metals to the
Egyptian consumers. In addition, consumption of cheese will provide part of the human
needs of the essential trace elements including Zn, and Cu.
