What is the main concern regarding washing fruits and vegetables with ozonated water?

The correct answer highlights an important aspect of using ozonated water in washing fruits and vegetables. Ozonated water is known for its powerful oxidizing properties, which can efficiently eliminate bacteria and other pathogens from the surface of produce. This increased effectiveness compared to regular water supports food safety by reducing the risk of foodborne illnesses.

While the other options present valid considerations, they do not capture the central benefit of ozonated water. Safety concerns, potential changes in taste, and the possibility of harm to the produce are factors that can be evaluated, but they are secondary when considering the primary purpose of using ozonated water: its enhanced disinfection capability.
