Abstract

Eighty random samples of cheese (Kariesh, Damietta, Romy and Edam cheese) were collected from different localities in Cairo, Giza and Kanoble Governorates. Samples were examined for nitrites concentra­tions and total bacterial contamination. Results showed that nitrites concentration ranged from 0.0 : 9.8 t 4.6 mg/kg, while, the total bac­terial count ranged from 360 ± 16.33 to 25590 ± 9256.33 C.F.U. There was a negative correlation between nitrites and total bacterial count in Kariesh and Romy cheese. It appears necessary to examine all types of cheese before solding to confirm a good hygienic quality.
