Abstract

Sixty random samples of chicken luncheon and beef luncheon (30 samples of each) were collect-ed from markets in different governorates (Cairo, Giza, Zagazig , Alexandria and Beni Suef). All collected samples were subjected to bacteriological and chemical examinations. Bacteriological examination revealed that the mean counts of Bacillus cereus were 0.47 X 102 ± 0.16 X 102 and 0.67 X 102 ± 0.22 X 102 CFU/ gm , while the mean values of anaerobic bacterial count were 0.4 X 102 + 0.17 X 102 and 0.37 X 102 + 0.14 X 102 CFU/ gm for chicken luncheon and beef lunch-eon, respectively. Chemical examination revealed that the mean values in chicken luncheon and beef luncheon were 50.6% & 51.47% ,9.6 & 9.05% ,18.68 18.74% ,0.73 & 0.08 for water contents, protein contents, fat contents and thiobarbituric acid (malonaldehyde/Kg) respectively, where the maximum values of nitrite contents in the two products were 130 & 128 ppm, respectively.
