Abstract

BACKGROUND: Microbiological and chemical qualities of
milk are among the most important issues in public health.
OBJECTIVES:Although there are a few published studies which
have been conducted in south east of Iran this study was
performed to investigate quality of raw milk delivered to a dairy
industry company Kerman Province. METHODS:Atotal of 109
raw milk samples were collected at the time of delivering to the
company. All the samples were transferred to the food lab of
Veterinary School for total counting and psychotropic and
Staphylococcus aureus counting. The chemical contents,
residues of microbial inhibitors and Beta Lactam antibiotics
residues were evaluated by Lactostar, Copan kit and Beta star
test, respectively, and somatic cells were counted by a cell
counter. RESULTS: Based on the comparison with national
standard criteria, only 26 out of 109 samples (23.8; 95% CI: 16.2-
33.0) were at standard limits in terms of all the factors. Alarge
number of out-of-standard sample (50 out of 83), were in contrast
with the defined criterion due to low protein. CONCLUSIONS:
Classification of the samples based on all the defined criteria
without considering protein content showed that the main
problem of the milk was its low protein percent.
