What three characteristics make some foods potentially hazardous?

The characteristics that make some foods potentially hazardous are high protein, low acidity, and high moisture, which aligns with the correct answer.

Foods that are high in protein provide an ideal environment for the growth of bacteria, as many pathogens thrive on protein sources. Additionally, low acidity means that these foods do not have a natural defense against bacterial growth since more acidic environments can inhibit or kill harmful microorganisms. High moisture content also contributes significantly to food safety risks, as moisture is essential for the survival and multiplication of bacteria. Foods that combine these three characteristics can support rapid bacterial growth if they are not properly stored or cooked, increasing the risk of foodborne illnesses.

This understanding emphasizes the importance of proper food handling and storage practices to minimize the risk associated with potential hazards in food preparation and service.
