Determination of the counts of psychrotrophic bacteria offers an important indicator of the technological quality of purchased raw milk, and also an indicator of the hygienic level of its production in agricultural primary production, particularly with respect to the sanitation of milking machines.

Since the level of the microbial quality of raw milk should be increased, we investigated and developed convenient methods of determination of psychrotrophic bacterium counts in the last years (U r b a n o v a et al., 1988
