Evaluation of the Hygienic and Microbiological Quality of Raw Milk from Cows Intended For Consumption or Processing in the Town of Abéche in Chad.

Abstract

The objective of this study was to identify the sources of microbial contamination of was milk and to evaluate the degree of microbiological contamination of was milk, to isolate the suspected pathogenic germs in the milk consumed. A total of 30 farmers were surveyed simultaneously at the time of collecting 30 samples. The samples were immediately transferred to the laboratory for microbiological analysis. Pathogens were investigated according to standard microbiological methods. The analysis of was milk made in the laboratory of INSTA chowed that the load of FAMT was variable between 4, 00.104 cfu /ml to 7, 15.107 ufc /ml, those of CT and CF were included between 103 cfu / ml to 5,73.104 cfu /ml and staphylococcus aureus was between 1,36.102 cfu /ml to 4.5.103 cfu /ml. the microbiological quality of the raw milk samples according to FAMT, CT and CF were mostly unsatisfactory. The microbiological quality of the raw milk sample according to staphycocus aureus was mostly uncontaminated. In the light of these results, the improvement of the microbiological quality of milk based on the establishment of a quality policy, aimed at popularizing the application of good hygiene practices throughout the chain of milk production and veterinary monitoring could contribute to improving product quality.
