The Influence of Non-Stripping on the Bacterial Count of Machine-Drawn Milk1

ABSTRACT

Two practices have developed which make timely a consideration of the influence of non-stripping of cows on the bacterial count of machine-drawn milk. In the first place the bacterial count of milk is used extensively in milk control work as a measure of the cleanliness and desirability of the product. While the types of bacteria present should receive more consideration perhaps than commonly accorded them, yet it is true that large numbers of bacteria are often associated with carelessness in producing and handling the milk. For this reason, the bacterial count serves a useful purpose in giving some indication of the quality of the milk.

If the bacterial count is to be used as an indication of quality and hence in determining to some extent the price received, it becomes important to consider production practices which may affect the number of bacteria present.

Then, in the second place, another practice is introduced for consideration.
