Abstract
The current study was undertaken to assess the bacteriological quality of raw camel milk and to isolate and identify prevalent bacterial species from raw camel milk from study areas. A total of 420 milk samples (384 from lactating camels and 36 from milking utensils) were collected from August 2011 to April 2012. An observational study was conducted to gain an insight on pre-harvest. harvest and post-harvest milk hygiene practices. The standard plate count and coliform count as well as isolation and identification of bacteria from camel milk were carried out by employing standard microbiological techniques. The mean standard plate count for milk sample taken from the udder of' lactating camels and milking utensils were 4.30 log10 CFU/ml and 5.34 log10 CFU/ml, respectively. A statistically significance difference was observed between the two means (P= 0.000). The mean coliform count of milk samples collected from the udder of lactating camels and milking utensils were 0.98 log10 CFU/ml and 3.57 log10 CFU/mI. respectively. There was also a statistically significant difference between the two mean (P=0.000). Clinically mastitic udder have role as a source of' Staphylococus aureus,S.hicu,.Streptococcus galactic. S. dysgalactia. Enlerococcus faecalis. Bacillus spp Eschericia coli and Mannheimia hemolytica in camel milk. Subclinical mastitis acts as a source of contamination for microbes such as Staphylococcus. aureus, S. hyicus, S. intermedius. Enterobacter aerogenes,Escherichia coli and Cyanobacteria spp .. Likewise, milk form the also yielded several bacteria which included S. aureus, S. epidermidis, Streptococcus agalactiae, S. uberis, Enterococcus faecalis, Klebsiella pneumonia and Pseudomonas spp .. On the other hand, milking utensils served as an important source of' Escherichia coli and Staphylococcus epidermidis. A higher bacterial counts was observed in milk samples taken from milking utensils as compared to the milk samples collected directly from the udder indicating poor milk hygiene/ manufacturing practices. The prevalence of infectious mastitis can result in reduced milk yield and poor quality of milk. In addition, consumption of' raw camel milk by herdsmen may pose considerable health hazards
