Food safety is of particular importance for which of the following groups?

Adults over the age of sixty-five have a weaker immune system, which makes them more susceptible to foodborne illness. They are also more likely to have chronic health conditions, which can make them more vulnerable to complications from food poisoning.
Children under the age of six have an immature immune system, which makes them more susceptible to foodborne illness. They are also more likely to eat foods that are raw or undercooked, which can increase the risk of food poisoning. People with immunodeficiency have a weakened immune system, which makes them more susceptible to foodborne illness. This includes people with HIV/AIDS, cancer, and other chronic health conditions.
