Mozzarella cheese can be eaten during pregnancy as long as it is made from pasteurized milk. Pasteurized mozzarella is safe because the pasteurization process kills harmful bacteria like listeria, which can be dangerous during pregnancy. It's recommended to consume pasteurized mozzarella 2 to 3 times a week as part of a healthy diet. Avoid mozzarella made from unpasteurized milk to reduce the risk of bacterial contamination. Pizza with mozzarella is also generally safe if the cheese is pasteurized. Additionally, mozzarella provides beneficial nutrients like calcium and protein that support both maternal and fetal health during pregnancy.
