| Abstract |
|
Milk is very susceptible to
growth and development of many microorganisms because it is rich in
nutrients and has suitable condition for the growth of microbes. The
objective of the present investigation was to determine the total
bacterial count and prevalence of
Escherichia coli in raw milk from milk collection centers in
Markazi
Province. A total 248 milk
samples were collected from 31 centers in November 2012 and were
analyzed according to standard methods to find the prevalence of
E. coli. None of the raw milk samples under investigation, had
superior or grade 1 quality. Only 9.09% of the samples were classified
with grade 3 quality and 90.9% were non-standard. The mean of microbial
total count in logarithm base were 6.8±.44 and average prevalence of
E. coli in the samples was 29.14%. The cities of Arak and Shazand have the lowest and the
highest microbial total count, respectively. In general, the result of
this study showed unsatisfactory conditions of the milk in milk
collection centers of the Markazi province.
