If a food contact surface is in constant use, how often should it be cleaned and sanitized to prevent microbial contamination?

• A. Only when visibly dirty
• B. At least every 4 hours
• C. Every 8 hours
• D. Once per day

Answer: (B)

Verified step by step guidance

1. Understand the importance of cleaning and sanitizing food contact surfaces: These surfaces can harbor microbes that cause contamination and foodborne illness if not properly maintained.
2. Recognize that constant use of a food contact surface increases the risk of microbial buildup, making frequent cleaning and sanitizing necessary to control contamination.
3. Recall food safety guidelines, which recommend cleaning and sanitizing food contact surfaces at regular intervals to minimize microbial growth and cross-contamination.
4. Identify the standard recommended frequency for cleaning and sanitizing surfaces in constant use, which is typically at least every 4 hours to maintain a safe environment.
5. Conclude that cleaning and sanitizing only when visibly dirty or less frequently (such as every 8 hours or once per day) is insufficient to prevent microbial contamination in high-use scenarios.
