CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND INFORMATION
Milk
is defined as a secretion of mammary gland of female animals. It is an
exceptionally good source of protein which is of a high biological value
in promoting the growth of children (ihekorany and Ngoddy, 1985). Milk
is decribed as a good of outstanding interest, which is designed by
nature to be complete good for very young mammals (fox and Cameron,
1980).
Milk contains a wide variety of constituents and contains
most of the food factors associated with bacterial nutrition. Milk as a
single food is of high nutritional value and is associated with spoilage
microorganisms. At the time milk leaves the udder of the healthy cow,
it contains few bacteria these stem from milk ducts and cistern. During
the milking process, bacteria are usually added from various sources.
In hand milking the sources are air the hair of the animal manure, the
milkers equipment such as pails, feed and machine, most of these
environmental factors are less important. However, the milking equipment
may serve as an important source of contamination if it is not
carefully cleaned and sanitized (ihekoronye and Ngoddy, 1985) .
After
milk has been drawn it is rapidly cooled to 45 of prevent contaminants
from multiplying. To eliminate pathogens from milk the process of
pasteurization is applied. This involves application of heat below the
boily point (fraizer and westhoff, 1978).
1.2STATEMENT OF PROBLEM
Mike
as a food of high nutritional value is highly associated with
microorganisms. As a result of this contamination of raw milk, it not
sterilized and taken directly or used for production of milk products,
causes disease to man and also contribute to the spoilage of milk and
milk products.

ABSRACT - [ Total Page(s): 1 ]Microbial evaluation of twenty samples of raw milk from a diary farm (Emene fulani cattle rearers) was carried out using five method: viz direct microcopies count nutrient agar count, Blood agar count, Mac conkey agar count (celiforms only) and Acid fast bacilli staring was done to assay for the presence of the Tubercle bacillus. The bacterial was were as follows: direct microscopic counts ranged from 9.0x 105to 9.5 x 107 counts on Nutrient agar ranged from 9.0 x 104 to 8.0x 105 counts on bl ... Continue reading---
