Can pregnant women eat Vienna sausages?

Pregnant women should avoid Vienna sausages and other processed meats because they may contain harmful bacteria, such as Listeria monocytogenes, which can cause listeriosis. Listeriosis is a serious infection that can lead to miscarriage, premature birth, and other complications. Vienna sausages are also generally high in nitrates, which may reduce the amount of oxygen that goes to the uterus.
