A critical limit distinguishes between safe and unsafe operating conditions at a CCP.

• A. True
• B. False
• C. Sometimes
• D. Unknown

Answer: (B)

The main idea is that a critical limit is the boundary value a process parameter must meet at a CCP to ensure safety. It’s the measurable threshold—such as a minimum cooking temperature, a maximum time, a minimum/maximum pH, or a specific cooling rate—that defines safe operation. When the process stays within these limits, the hazard is controlled; if the limit is exceeded or not reached, control is lost and corrective actions are needed to prevent unsafe product. So the statement is accurate: a critical limit distinguishes between safe and unsafe operating conditions at a CCP. For example, reaching the required internal temperature during cooking or cooling to a safe temperature within a set time illustrates how these limits function in practice.
