Question

if heated water is used to sanitize, it must be at?
171f for 30 seconds
200f for 5 seconds
225f for 5 seconds
145f for 30 seconds

Explanation:

In food safety and sanitation, when using heated water for sanitization, the correct temperature - time combination is 171°F for 30 seconds. This is a standard in food service sanitation guidelines where hot water sanitization requires a temperature of at least 171°F for a contact time of 30 seconds to effectively kill microorganisms. The other options either have incorrect temperatures or incorrect time - temperature combinations for effective sanitization.

Answer:

A. 171F for 30 seconds
