Which of the following groups is most susceptible to foodborne illnesses caused by listeria?

1. Children under 5 years old

2. Elderly individuals

3. Pregnant women

4. All of the above

The correct answer is: All of the above

The susceptibility to foodborne illnesses caused by listeria is higher in certain groups due to their weakened immune systems or specific health conditions. Listeria monocytogenes can lead to severe infections and complications in these populations, making them particularly vulnerable. Children under 5 years old are more likely to experience severe outcomes from infections because their immune systems are still developing. Elderly individuals often have weakened immune systems, making it harder for their bodies to fight off infections. Pregnant women are especially at risk since listeria can cross the placenta, potentially leading to miscarriage, stillbirth, or serious illness in newborns. Considering these points, it is clear that all of these groups—children, the elderly, and pregnant women—share a heightened vulnerability to listeria-related illnesses, highlighting the importance of proper food safety practices to protect them from contamination.
