Gorgonzola is generally not considered safe to eat during pregnancy when served cold or uncooked, even if it’s made from pasteurized milk. The CDC lists blue-veined cheese among its riskier choices for pregnant women. However, gorgonzola that has been heated to an internal temperature of 165°F (until steaming hot) is considered a safer option.
Why Gorgonzola Carries Extra Risk
Blue cheeses like gorgonzola are made differently from most other cheeses. During production, the cheese is pierced with needles to let air reach the center, which allows the signature blue-green mold to grow. That same needling process can introduce harmful bacteria into the interior of the cheese. The mold also makes the inside of the cheese less acidic over time, creating conditions where listeria (the main bacteria of concern) can survive and multiply more easily than it would in other cheeses.
A Food Standards Agency review found that gorgonzola rinds are far more likely to be contaminated than the center of the cheese, but cutting and portioning can spread bacteria from the rind inward. Listeria can also enter through raw milk, the brine used during production, or during handling and packaging. Because blue cheeses are so microbiologically active and variable in their acidity, moisture, and salt levels, the risk is harder to predict and control than with other cheese types.
Pasteurized Gorgonzola: Safer but Not Risk-Free
Pasteurization kills listeria in milk before cheesemaking begins, and some sources do list pasteurized blue cheeses as safe during pregnancy. But the CDC’s most recent guidance (updated January 2025) still recommends that pregnant women only eat soft pasteurized cheeses if they’ve been heated to 165°F or until steaming hot. This is because listeria can be reintroduced after pasteurization, during the weeks of aging, handling, cutting, and packaging that follow.
If you’re buying gorgonzola in the U.S., check the label for the word “pasteurized.” U.S. regulations require that any cheese made from unpasteurized milk be aged at least 60 days at a minimum temperature of 35°F. But aging alone doesn’t eliminate listeria reliably in soft blue cheeses, which is why the cooking recommendation still applies regardless of pasteurization status.
How to Eat Gorgonzola Safely
The simplest way to enjoy gorgonzola during pregnancy is to cook it thoroughly. Melting it into a pasta sauce, baking it on pizza, or stirring it into a hot risotto all work, as long as the dish reaches that 165°F internal temperature or is visibly steaming throughout. At that heat, listeria is killed. A crumble of cold gorgonzola on a salad, however, doesn’t meet that threshold.
If you’re eating out and a dish contains gorgonzola, it’s worth asking whether the cheese was cooked into the dish or added after. A gorgonzola cream sauce that simmered on the stove is a different situation from a few cold crumbles placed on top of a warm steak.
Why Listeria Is Especially Dangerous in Pregnancy
Pregnant women are significantly more susceptible to listeria infection than the general population. The infection, called listeriosis, typically feels like a mild flu: fever, chills, muscle aches, diarrhea, or upset stomach. Some women experience a stiff neck, headache, or confusion. Others have no symptoms at all. That’s part of what makes it tricky: you can be infected without realizing it.
Symptoms can take up to two months to appear after eating contaminated food, which makes it difficult to trace back to a specific meal. The real danger is to the baby. According to the CDC, nearly 25% of pregnancy-associated listeriosis cases result in fetal loss or death of the newborn. Infection during pregnancy can lead to miscarriage, stillbirth, preterm labor, or serious infection in the newborn including sepsis or meningitis. Although severe illness in the mother herself is rare, the consequences for the pregnancy can be devastating.
What If You Already Ate Cold Gorgonzola
If you’ve already eaten uncooked gorgonzola, there’s no need to panic. The overall incidence of listeriosis is low, and not all gorgonzola is contaminated. What matters is watching for symptoms over the following weeks. Because the incubation period can stretch to two months, keep an eye out for fever, flu-like aches, digestive upset, or any unusual symptoms during that window. If any of those develop, let your healthcare provider know what you ate and when.
Alternatives With a Similar Flavor
If you’re craving that tangy, sharp flavor and don’t want to bother with cooking, hard cheeses are a safer bet during pregnancy because their low moisture content makes them inhospitable to listeria. Aged parmesan or aged cheddar can satisfy that sharp, salty craving. For something closer to the blue cheese flavor profile, look for pasteurized blue cheese options and heat them into cooked dishes. Saga blue, a mild Danish blue cheese, is one widely available option that works well melted into sauces or baked dishes.
