Which of the following is an example of kitchen hygiene?

Having a cleaning schedule is an essential aspect of kitchen hygiene because it helps ensure that all surfaces, equipment, and utensils are regularly cleaned and sanitized. This practice minimizes the risk of cross-contamination and the growth of harmful bacteria, thereby promoting food safety. A well-maintained cleaning schedule includes regular tasks such as sanitizing countertops, cleaning floors, and washing equipment, which contribute to a healthy environment for food preparation.

In contrast, holding food at room temperature can encourage the growth of bacteria, using frozen ingredients does not directly ensure hygiene measures, and not wearing gloves while cooking poses a risk of contamination from hands to food.
