Assessment of Bacteriological Quality of Raw Bulk Milk of Camel, Cow and Goat from Local Markets in Yabello District, Borana Zone, Oromia Regional State
The study was conducted from September 2020 to June 2021 to assess the bacteriological quality of raw bulk milk from urban and rural local market sites in Borana pastoral area of Oromia Regional State, Southern Ethiopia. A total of 78 milk samples were collected and analyzed for bacterial load using standard plate count and coliform count techniques and isolation of pathogenic bacteria was conducted. The total mean aerobic bacterial counts of raw bulk milk samples of camel, cow and goat were 8.51 log cfu/ml, 8.73 log cfu/ml and 8.54 log cfu/ml respectively. Regarding the location of milk market sites, the mean total aerobic bacterial count was 8.72 log cfu/ml and 8.49 log cfu/ml in urban and rural milk market sites respectively. The total mean coliform counts of raw bulk milk samples of camel, cow and goat were 6.51log cfu/ml, 6.55 log cfu/ml and 6.47 log cfu/ml respectively. Regarding the location of milk market sites the total mean coliform counts was 6.63 log cfu/ml and 6.40log cfu/ml from urban and rural milk market sites respectively. Comparing the mean differences of the total mean aerobic and coliform bacterial counts, there was no significant mean differences (p>0.05) among the animal milk samples. However, there was significant mean differences (p<0.05) among the milk market sites. Different bacterial species were isolated from camel, cow and goat raw milk sample from the urban and rural milk market sites. The major bacterial isolates were Staphylococcus (both pathogenic and non-pathogenic), Escherichia coli and Bacillus species. Generally, the unhygienic milk handling resulted in poor milk quality in the pastoral area. Therefore, there is a need of training for persons at the various milk market sites on strict hygienic measures to improve the bacteriological safety of cow milk.
Bacteriological Quality of Milk in Raw Bovine Bulk Milk in the Selected Milk Collection Centers: Smallholder Dairy Processing Ethiopia
Cross-sectional study was conducted to examine and identify quality of raw bovine milk from in Arsi Zone and East Shewa Zone, in Oromia, Ethiopia. The purpose of the study was to assess hygienic practices during milking, milk collection and bacteriological quality of cow’s milk in Arsi and East Shewa Zones milk collection centers.
