If frozen milk particles are observed in a tank, how should the sampler mark the sample containers?

When frozen milk particles are found in a tank, it is crucial to indicate the condition of the sample clearly. Marking the sample containers with "ICE" specifically denotes the presence of frozen components within the sample. This helps ensure that anyone handling or analyzing the sample understands its state, which is critical for evaluating its quality and applicability.

Using "ICE" communicates that the sample might not react or behave in the same way as liquid milk during testing or further processing, as frozen particles can affect measurements and other analytical results. This clear labeling is essential for maintaining the integrity of quality control procedures in dairy processing and ensuring accurate assessments of the sample.

Other markings, such as "FROZEN," while related, may not communicate the specific issue with frozen particles as directly as "ICE." Marking with "NOT USABLE" might imply that the sample has been contaminated or is unfit for any analysis, which may not be true, as the sample could still be useful for certain tests but merely not in its current state. "SAMPLE TAKEN" simply denotes that a sample has been collected but does not indicate any specific concerns regarding its quality. Thus, the choice of "ICE" is the most effective for conveying critical information about the sample's condition
