What precaution must be taken for all fruits and vegetables served raw?

The requirement that all fruits and vegetables served raw must be thoroughly washed before serving is crucial in ensuring food safety. Washing helps to remove dirt, pesticides, bacteria, and any other contaminants that may be present on the surface of the produce. This process significantly reduces the risk of foodborne illnesses that can arise from consuming contaminated raw fruits and vegetables.

Thorough washing is especially important because fruits and vegetables can come into contact with various pathogens during their growth, harvesting, and transportation. By implementing this precaution, food handlers can promote health and safety in food service settings, ensuring that the produce is safe for consumption.

While the other options may relate in some way to food presentation or sourcing, they do not directly address the critical aspect of ensuring the safety and hygiene of raw produce before it is served.
