Which statement is true about dishwashers?

• A. They must be posted with the recommended cleaning schedule
• B. They must be posted with the correct operation settings
• C. They require no posted instructions
• D. They should be posted with energy usage guidelines

Answer: (B)

Posting the proper operating instructions for a dishwasher is essential for safe operation. When the correct operation settings are visible to staff, they can select the appropriate cycle, temperature, detergent, and sanitizer for each load. This ensures dishes reach the required sanitation levels, removes residues effectively, and minimizes the risk of cross-contamination. While other postings like cleaning schedules or energy guidelines can be useful, they don’t directly guarantee proper sanitation if the machine isn’t set correctly. So having the correct operation settings posted is the best practice for safe, effective dishwashing.
