Between which tasks is a cutting board required to be cleaned and sanitized?

• A. After cutting raw pork and dicing raw carrots
• B. After cutting raw pork only
• C. After dicing raw carrots only
• D. At the end of the shift

Answer: (A)

Preventing cross-contamination hinges on cleaning and sanitizing between tasks that involve different foods. After you finish cutting raw pork, you should clean and sanitize the cutting board before you start dicing raw carrots. This breaks the path for any pork bacteria to move onto the carrots. Cleaning only after pork or only after carrots would still allow cross-contamination during the next task, and waiting until the end of the shift lets contamination linger on the board. So the safest practice is to sanitize between tasks, i.e., after handling raw pork and before handling raw carrots.
