How often should equipment used for dairy products be sanitized?

• A. Between uses and at shift end, and whenever equipment becomes contaminated or dirty.
• B. Once per week.
• C. Only at the end of the day.
• D. Never unless there is a spill.

Answer: (B)

Regular sanitation of dairy equipment is essential to prevent contamination and keep products safe. Because dairy foods are highly perishable and rich in nutrients, residues can quickly support bacterial growth and even form hard-to-remove biofilms if not cleaned promptly. That means cleaning and sanitizing should happen between uses and at the end of each shift, and whenever equipment becomes contaminated or dirty. Cleaning removes visible soil and milk residues, and sanitizing kills remaining microorganisms on contact surfaces, helping prevent cross-contamination in every subsequent batch. Relying on a schedule like once per week leaves too much time for residues and microbes to accumulate, increasing the risk of spoilage and illness. Additionally, follow proper sanitation practices such as using the correct sanitizer, maintaining proper concentration and contact time, rinsing if required, and allowing surfaces to air dry before reuse.
