Raw milk, Kariesh cheese, Fetta cheese and yoghurt obtained from small shops and retailer venders showed high rate of contamination. Forty-four percent of raw milk samples were found to be contaminated. Kariesh cheese from factories or small shops were also contaminated. Its contamination reached up to 72%. Fetta cheese samples from small shops contained up to 24% contamination. Even 12% of yoghurt samples being obtained from small shops were found to be contaminated with12%. On the other hand, UHT milk and dried milk samples were completely free of the contamination. | ||
