The bacterial load prior to the pasteurization affects the efficiency
of pasteurization. This research was carried at the Milco dairy factory,
milk chilling centers and farmers’ fields in Sri Lanka to investigate
possible causes for microbial load of raw milk received by the factory.
Milk samples obtained aseptically from bowsers reaching the factory
were used for microbiological analysis and evaluation of quality by using
platform tests. Time taken for transportation of chilled milk contributed
most on the bacterial density of raw milk. Improper field level practices
were also identified as the other major contributing factor. The quality of
raw milk is high in Ampitiya, Anamaduwa, Dodangaslanda, Galgamuwa,
Norwood, Kotagala and Maho where better sanitary conditions were
observed at field level. Poor sanitary conditions in dairy farming in Galle,
Gonapinuwala, Horana, Nittambuwa, Moonamaldeniya, Polgahawela
and Thihagoda resulted in high initial bacterial density. It is concluded
that, time taken for transportation of chilled milk is a major factor
affecting microbial load at the reception of milk at the processing
factory, while good field level practices should be maintained to improve
the quality of milk.
