How long must objects be immersed in water to manually sanitize, at a minimum temperature of at least 171 F?

1. 15 seconds

2. 20 seconds

3. 30 seconds

4. 45 seconds

The correct answer is: 30 seconds

To manually sanitize objects by immersion in water at a temperature of at least 171°F, the minimum necessary time for effective sanitization is 30 seconds. This time frame is supported by food safety guidelines that ensure pathogens are adequately reduced on surfaces. When items are exposed to hot water at this specified temperature for 30 seconds, it provides sufficient exposure for the heat to effectively kill most harmful microorganisms that could cause foodborne illness. Sanitizing at this temperature for a shorter duration may not ensure that all pathogens are eliminated, potentially risking food safety. The choice of 30 seconds strikes a balance between efficiency and effectiveness in sanitization practices, making it the correct answer in maintaining safe food handling and preparation standards.
