Listeria infection is particularly severe in pregnant women due to the unique physiological changes that occur during pregnancy, such as an altered immune system. This increased susceptibility to infection can lead to serious complications, including miscarriage, stillbirth, preterm labor, and severe illness in newborns.

Pregnant women are at a higher risk because Listeria can cross the placental barrier, potentially affecting the fetus directly. The consequences of Listeria infection in pregnant women can be disproportionately severe compared to other groups, including healthy adults and children. While other groups, such as adults over 50, are also at risk, pregnant women are considered the most vulnerable population when it comes to the implications of Listeria infection.

This understanding of risk factors emphasizes the importance of food safety practices in protecting vulnerable populations, especially during pregnancy.
