Cheese during pregnancy
Most cheeses are fine to eat during pregnancy. Hard cheeses like cheddar and parmesan and soft pasteurized cheeses are safe (and tasty) to eat in moderation. Almost all cheese made in the United States is pasteurized by default, but you can find unpasteurized cheese at a farmer's market or buy imported cheese at the grocery store. During pregnancy, avoid unpasteurized soft cheese because it may contain listeria, a type of bacteria that can cause listeriosis. This infection is rare but especially dangerous for pregnant women.
If you accidentally eat a cheese that falls into the unsafe category, try not to worry too much. The Centers for Disease Control and Prevention reports that about 1,600 people get sick from listeria bacteria yearly. About 260 of them die.
If you feel sick, check yourself. You may experience diarrhea or an upset stomach first. In the meantime, please contact your physician if you have questions about your potential exposure. Your doctor may draw your blood to check for infection and give you antibiotics if necessary.
