Background: The microbiological quality of raw milk is relatively a new subject that interest more actors of milk production in Algeria. Until now, the raw milk collected presented a high rate of microbial contamination, prejudicial for human consumption and dairy processing. Objective: The aim of this study is to assess the hygienic and sanitary quality of raw milk produced throughout three segments where milk is handled in Tizi Ouzou area (Algeria). Methodology: For this, 174 samples of raw milk were collected throughout farms, collectors and local markets and submitted for microbiological analysis. Results: The results of this study showed that microbial contamination of raw milk increase along the dairy chain. The mean log10 of TBC at farm level was 6.73±0.25 log10 CFU mL–1. This value increase to reach a load of 6.81±0.19 and 7.2±1.05 log10 CFU mL–1 at collection centers and market points, respectively. In addition, cases of contamination by S. aureus and antibiotic residues were observed. Conclusion: This study suggest that improving of microbial quality of raw milk requires the establishment a quality policy with the training of farmers on good hygienic practices. |

The mineral content and its distribution among soluble and colloidal phases of milk from two ewe’s breed (Ouled-Djellal and Rumbi) (n = 20 each) reared in Algerian area steppe, were studied. The ewes were balanced for age and weight. All were in middle period of lactation. Individual milk samples were taken from each ewe third time from lactating period during spring season. Major elements of milk samples were slightly higher in milk from Rumbi than from Ouled-Djellal breeds. Results show that only Potassium, Sodium and Zinc were significantly influenced by breed type. Rumbi ewe’s milk gave the highest values (p ≤0.05) (1056±47.76, 667±79.75 and 7.7±0.99 ppm) than Ouled-Djellal ewes (974±18.83, 667±92.49 and 7.7±1.39 ppm, respectively). The average contents of trace elements in this study arranged according to the following order Zn<Fe<Cu<Mn. Mineral elements are unevenly distributed among soluble and colloidal phases of ewe’s raw milk analyzed. Algerian milk from sheep breeds constitutes a source of minerals especially for rural population. |
