The study was conducted to evaluate the chemical composition and microbial contents of Romi cheese in Khartoum state. Sixty samples of Romi cheese (30 samples from each of plastic and paper packs) were collected randomly from three different areas (Khartoum North, Omdurman and Khartoum). The manufacture date of cheese samples was defined to fixed date. Samples were examined for chemical composition and microbial contents under different packing materials. The packaging materials significantly affected the chemical composition of the Romi cheese samples (P< 0.01) the higher chemical parameters were in Romi cheese samples in paper pack (29.40±1.41; 25.76±2.04%; 64.40±4.12%; 0.99±0.25%; and 11.42±1.43ml NaOH/100g cheese for fat, protein total solids, titratable acidity and volatile fatty acids respectively, while the ash content was higher (4.45±0.80%), in plastic pack. The highest in plastic package and the lowest in paper pack. The minerals content (Phosphorus and Potassium) were higher in Romi cheese samples in plastic pack while the Calcium was higher in Romi cheese samples in paper pack. The results indicated that 9 % of the collected Romi cheese samples showed presence of yeast and molds, 3.3 % of the samples demonstrated the presence of Staphylococcus aureus, 1.6 % of samples indicated the presence of coliforms and E. coli, Salmonella and Listeria monocytogenes were not detected in the cheese samples in Khartoum state. Romi cheese samples in plastic packed revealed high microbial load in comparison with paper pack.
