If a license sampler weigher finds a sample bottle to be wet inside before taking a milkfat sample, what should they do?

When a license sampler weigher discovers that a sample bottle is wet inside before taking a milkfat sample, rinsing the bottle with the product to be sampled is the correct action because it ensures that any residual moisture does not contaminate the sample. The aim is to maintain the integrity of the sample, which is critical for accurate testing. By using the product itself for rinsing, any residues that could affect the milkfat content measurements will be eliminated, allowing for more reliable results.

Moreover, rinsing with water would introduce a foreign substance that could dilute the milkfat sample, compromising the test results. Discarding the bottle might be overly cautious, as rinsing appropriately is a practical solution. Using a different sample bottle could also be a valid option, but the most effective method to ensure the bottle is clean and ready for sampling is to use the product itself. This technique reflects a standard practice in sample collection for maintaining the quality and accuracy of the test results.
