Milk has a natural microbial flora and has a risk of inadvertent contaminat
ion during collection and subsequent processing. Components of this flora a
re human pathogens so through the food chain from milking to man, these pat
hogens have to be eliminated or controlled. Consumers are increasingly conc
erned about the safety of their food. The dairy industry has an impressive
record of food safety as a small percentage of foodborne illness outbreaks
recorded now in developed countries are milk related. Food safety programs
have been in place within the dairy industry beginning with its widespread
acceptance of heat pasteurisation of raw milk and have been progressively d
eveloped in reaction to challenges such as foodborne listeriosis. However,
there is no room for complacency as strict control is required continuously
in food safety programs and vigilance is required in monitoring challenges
from new and emerging microbial hazards and food innovations.
