In addition to taking correct measurements and representative samples, what else must samplers and weighers ensure?

Handling milk equipment in a sanitary manner is crucial for samplers and weighers because cleanliness directly impacts the quality and safety of the samples being collected. When working with perishable and sensitive products like milk, any contamination can compromise the integrity of the samples and lead to inaccurate test results. Sanitary handling practices help prevent the introduction of harmful bacteria or other foreign substances that could affect the sample's composition or lead to food safety issues. This requirement aligns with health regulations and industry standards aimed at safeguarding consumer health, thus making it essential for samplers and weighers to prioritize sanitary practices in their work processes.
