Answer :
Final answer:
The final rinse cycle of a dishwasher must reach a minimum of 165 degrees Fahrenheit to ensure sanitization without a sanitizing agent, as this temperature is effective in killing bacteria.
Explanation:
The question asks about the minimum temperature required during the final rinse cycle of a dishwasher to ensure sanitization without the need for a sanitizing agent. According to guidelines on controlling bacterial growth, heating food or water to a high temperature, generally at least 74°C or 165°F, can kill bacteria. This principle applies to sanitizing dishes in commercial dishwashers, where high temperatures serve to eliminate microbes, ensuring the dishes are safe for use. Thus, the correct answer is b) 165°F.
