Abstract

Raw milk is highly nutritious product for human. Knowledge of its quality is essential for consumer protection and taking some relevant measures to improve dairy cattle livestock breeding. This study focused on nutritional and hygienic assessment of raw milk from 12 farms in the Maritime region in southern Togo. In total, 30 and 60 samples of raw milk were subjected to physicochemical and microbiological analyses respectively. Results of these analyses revealed these milks to be of sufficient nutritional quality with 31.64 ± 3.65 g / l of fat, 33.38 ± 0.56 g / l of protein, 45.93 ± 3.34g / l of lactose and 0.95 as value of Ca/P. hygienically, they contained on average 5.90 105 ufc / ml of total mesophilic aerobic flora with 40% of sample contamination to a level > 3.105 ufc / ml. Total and faecal coliform respective loads of 2.75 103 ufc / ml and 4.36 102 ufc / ml were present in 46.67% and 83.33% of samples; the faecal streptococci on average load of 2.78 102 ufc / ml were present in 33.33% of samples. The samples contents of Staphylococcus aureus (≤102 ufc / ml) showed that these germs were not present. But the milking practice and the delay in refrigeration of these milks had very significant (p <0.01) impact on the quantitative variation of the germs sought.
