Milk Sampling
Fluid raw and pasteurized milk products are routinely sampled under Pasteurized Milk Ordinance (PMO) requirements. The sampling tests for added water, heterotrophic bacteria, coliform bacteria, the presence of indicator enzymes, somatic (body) cell counts, and antibiotic or drug residues. These tests help to ensure that the milk received by retailers and consumed by end-users is of the highest quality.Samples are taken by bulk milk tank haulers, pasteurization plant personnel, and inspectors.
