For high-temperature dishwashing machines, why should the water temperature of the final rinse not exceed 194°F?

Water temperature can damage the dishwasher.
Water can evaporate before sanitizing the items.
Spray nozzles may become clogged with minerals.
Items may not dry properly.

The correct answer is: Water can evaporate before sanitizing the items.

The temperature of the final rinse water in high-temperature dishwashing machines should not exceed 194°F because excessively high temperatures can lead to rapid evaporation of water before it has a chance to effectively sanitize the items. Sanitization requires sufficient contact time between the hot water and the surface of the items being cleaned. If the water evaporates too quickly, it can hinder the sanitization process, leaving behind pathogens or food residues that can compromise food safety. In addition, extremely high temperatures can create a situation where the water does not remain in contact with the surface long enough to kill harmful microorganisms, which is essential to ensure that the dishware is safe for use. This underscores the importance of monitoring and regulating water temperature during the rinse cycle to achieve optimal sanitization results.
