Which populations are considered highly susceptible (high-risk) to foodborne illness and should be given extra protection?

解析

Highly susceptible populations are young children, older adults, pregnant women, and people with weakened immune systems, because their immune systems are still developing, declining, or compromised and a small dose of a pathogen can make them severely ill. Facilities serving these groups, such as hospitals and nursing homes, may not serve raw or undercooked animal foods or raw seed sprouts (FDA Food Code §3-801.11). A vitamin or whole-grain diet, athletic fitness, and how often someone eats out do not create this status.
