Which statement about high risk foods is correct?

• A. They are low in moisture.
• B. They are high in sugar content.
• C. They are high in moisture and low in acidity.
• D. They are preserved in cans.

Answer: (C)

High risk foods are those that provide favorable conditions for microorganisms to grow. The main factors are moisture and acidity: foods with high moisture (water activity) and low acidity (higher pH) support the multiplication of bacteria and other pathogens. That’s why the correct statement describes high risk foods as being high in moisture and low in acidity. Low moisture foods limit microbial growth, so that option isn’t right. Sugar-rich foods can be preserved by osmotic effects that reduce water activity, so high sugar content alone doesn’t define a high-risk food. And simply being preserved in cans doesn’t automatically make a food high risk; canning aims to reduce risk by controlling moisture, pH, and heat treatment.
