What must be done to melons, tomatoes, and leafy greens before they are held at temperature?

For melons, tomatoes, and leafy greens, washing them thoroughly before holding them at temperature is essential for food safety. Washing these items helps remove dirt, bacteria, and pesticides that may be present on their surfaces. These fruits and vegetables can harbor harmful pathogens that can cause foodborne illnesses if consumed without proper washing.

It's important to rinse them under running water and use a clean produce brush when necessary to ensure that any contaminants are effectively removed. This practice is vital in maintaining food safety standards and protecting consumers after the items are prepared for service or stored.

Other practices such as cooking, freezing, or cutting these items do not specifically address the immediate need for cleanliness and sanitation prior to holding them at temperature. Cooking and freezing are methods that alter the food's state rather than ensuring its safety in its fresh form, while cutting them into pieces may increase the risk of cross-contamination if the items have not been washed first. Hence, the primary focus should be on washing prior to any other handling or storage actions.
