While most types of pasteurized cheese are perfectly safe to consume during pregnancy, soft cheeses, such as feta, Brie and Camembert, should be avoided. According to Dr. Shannon Clark, an obstetrician/gynecologist and associate professor of maternal-fetal medicine at the University of Texas Medical Branch at Galveston, soft or unpasteurized cheeses can contain listeria, a potentially serious bacteria that can lead to miscarriage, premature delivery or even death. “The general rule of thumb with cheese is to consume only pasteurized cheese,” Dr. Clark advises. “Although rare, listeria infection in pregnancy is very dangerous,” she states. To be safe, stick to hard cheeses, such as cheddar, and read the labels to be sure the cheese you’re buying is pasteurized.
