Why should surfaces be sanitized after cleaning?

Sanitizing surfaces after cleaning is crucial because it significantly reduces the number of harmful organisms, such as bacteria and viruses, that could lead to foodborne illnesses. Simply cleaning a surface may remove dirt and debris, but it does not necessarily kill the pathogens that can survive on surfaces. The process of sanitizing, which typically involves the use of a chemical solution or heat, ensures that any remaining microorganisms are effectively eliminated, creating a safer environment for food preparation and handling. This step is essential for maintaining food safety standards and protecting public health, particularly in settings where food is prepared for consumption.
