What is the minimum temperature in degrees Fahrenheit required for high heat sanitizing?

• A. 160°F
• B. 171°F
• C. 180°F
• D. 150°F

Answer: (B)

High-heat sanitizing relies on hot water being used for a sufficient time to reduce or kill microorganisms. There’s a minimum temperature that still guarantees this sanitization when the usual exposure time is applied. That threshold is 171°F. Temperatures like 160°F or 150°F are too low to ensure sanitization within practical contact times. While 180°F would certainly sanitize, the question asks for the minimum temperature needed, and 171°F is that lower limit. In practice, many hot-water sanitizing processes target higher temps (like 180°F) to ensure rapid efficacy, but 171°F is the minimum at which sanitization is reliably achieved.
