Who are considered high-risk populations in food safety and why?

• A. Young children, elderly, pregnant women, and immunocompromised individuals; they are more susceptible to foodborne illness.
• B. Athletes and teenagers.
• C. Healthy adults who exercise.
• D. People with allergies only.

Answer: (A)

The main idea is identifying who is most vulnerable to illness from contaminated food and why some groups need extra protection.

High-risk populations are young children, older adults, pregnant people, and individuals with weakened immune systems. These groups are more susceptible to foodborne illness because their defenses or physiology make it harder to fight infections or tolerate symptoms. Young children have developing immune systems and smaller bodies, so dehydration and severe illness can happen quickly. Older adults often have weaker immune responses, more chronic health conditions, and changes in digestion that can increase risk. Pregnant people experience immune changes and are particularly at risk for certain pathogens like Listeria, which can affect pregnancy outcomes. Immunocompromised individuals—such as those undergoing chemotherapy, living with HIV/AIDS, or on immune-suppressing medications—have substantially higher risk of severe illness and complications from common foodborne pathogens.

Other groups like athletes, teens, healthy adults, or people with allergies do not have the same inherent elevated risk for severe foodborne disease, so they’re not classified as the high-risk population in this context.
