The samples were prepared for bacteriological analysis via observed and total viable count (TVC) of bacteria; Total coliform count.

Staphylococcus bacteria count.

Detecting of Salmonella and Examining culture (for identification and isolating Grams Stain bacteria).

The main results were as follow; TVC bacteria percentages in chicken and red meat Shawarma were (82 vs.

94) %, respectively; with values of (9x 104 vs.

14xl04) cfu/g, respectively.

The counterparts' percentages of Coliform contamination were (10 vs.

14) %, respectively; with values of (27xl02 vs.

2xI03) cfu/g, respectively.

Staphylococcus aureus, Staphylococcus epidermidis.

Salmonella, Shigella spp and Pseudomonas bacteria recorded (18, 12, 20, 24 and 2) %, respectively for both types of Shawarma.

The highest positive and significant (P<0.01) correlation coefficient was found between Staphylococcus aureus and Staphylococcus epidermidis count (0.762) in chicken's Shawarma.
