Blue Cheese in Pregnancy — Strong Flavour, Stronger Rules

Blue cheese is bold, salty, and complex — the star of cheeseboards, gourmet burgers, salads and steak sauces. In pregnancy, though, it sits firmly in the “handle with care” category.

Soft blue cheeses are exactly the kind of environment where Listeria monocytogenes can survive and grow: moist, mould-ripened and stored in the fridge. ^[1]

The good news? You don’t have to say goodbye forever. You just need to change how you eat blue cheese:

✔ Blue cheese cooked until steaming hot = safe ❌ Soft blue cheese eaten cold = unsafe
This guide walks you through what’s allowed, what’s not, and how to enjoy that flavour safely.

Quick Take (TL;DR)

Avoid soft blue cheeses cold (Roquefort, Gorgonzola, Danish blue, creamy crumbles). ^[2]
Blue cheese is safe when fully cooked into hot sauces, pizzas, gratins, or bakes. ^[4]
Pasteurization lowers risk but doesn’t change the cold-soft-cheese rule.
Stilton or hard blue cheese: lower risk if pasteurized, but many guidelines still err on the cautious side.
If in doubt, treat blue cheese as a “cook-only” cheese in pregnancy.

What Counts as Blue Cheese?

“Blue cheese” is a family of cheeses ripened with blue-green mould cultures (usually Penicillium roqueforti). They develop blue veins or spots and a tangy, sharp flavour.

Common blue cheeses include:

Roquefort — French, tangy, crumbly.
Gorgonzola — Italian, creamy or crumbly styles.
Danish blue — strong, salty, moist.
Stilton — English, firmer and more crumbly.
Blue cheese crumbles — salad and burger toppings.

Most of these are soft or semi-soft cheeses — the exact group pregnancy guidelines flag as higher risk.

Blue cheese stored in a glass container in the fridge — Store blue cheese at ≤4 °C / 40 °F, respect use-by dates, and avoid eating it cold in pregnancy. ^[3]

Why Blue Cheese Is a Listeria Risk

Listeria monocytogenes is a bacteria that can grow at refrigerator temperatures and is particularly dangerous in pregnancy. Soft blue cheeses provide:

Moisture — bacteria like water.
Mould-ripening — micro-environments that support growth.
Fridge storage — Listeria can still grow at low temperatures. ^[1]

For pregnant women, infection risk is higher and can lead to serious pregnancy complications. That’s why many national guidelines simply say: avoid soft blue cheese altogether unless cooked. ^[2]

Nutrition Snapshot — Rich & Intense

Blue cheese is nutrient-dense and very flavourful, so a little goes a long way.

Nutrient (per 100 g)	Approx.	Pregnancy Note
Calories	≈ 350 kcal	Energy-dense; use as a flavour accent.
Protein	≈ 21 g	Supports tissue growth.
Fat	≈ 29 g	High — combine with vegetables or whole grains.
Calcium	≈ 530 mg	Helps bone and tooth development.
Sodium	≈ 1,000 mg	Very salty; moderate if you have blood pressure concerns.

Steak or pasta topped with hot blue cheese sauce — Blue cheese is pregnancy-safe when fully cooked into a hot sauce, pizza, or bake — steaming all the way through. ^[4]

How to Still Enjoy Blue Cheese Safely

You don’t have to completely break up with blue cheese — you just need new “house rules” for pregnancy.

Use blue cheese in hot sauces for steak, chicken or vegetables.
Add it to pasta bakes or gratins and cook until bubbling.
Use as a topping on pizza that bakes in a very hot oven.
Avoid cold blue cheese crumbles on salads, burgers or crackers.
Avoid cold blue cheese dressing unless clearly pasteurized and heat-treated (and even then, many guidelines advise skipping it).

Myths & Facts

Myth: “All blue cheese is forbidden in pregnancy.”
Fact: Blue cheese is safe when fully cooked; the risk is with cold, soft blue cheese. ^[2]
Myth: “If it’s pasteurized, I can eat blue cheese cold.”
Fact: Soft blue cheeses are still usually advised against cold, because their moisture + mould make them higher risk. ^[1]
Myth: “The mould in blue cheese kills other bacteria.”
Fact: The mould doesn’t sterilize the cheese; Listeria can still grow if present. ^[3]

Pregnancy FAQ — Blue Cheese

Is blue cheese safe during pregnancy?

Soft blue cheese (like Roquefort, Gorgonzola, Danish blue) is unsafe when eaten cold in pregnancy due to Listeria risk. Blue cheese is only considered safe when it has been cooked until steaming hot. ^[1] ^[2]

Can I eat blue cheese dressing or blue cheese on salad?

It is safer to avoid cold blue cheese crumbles and cold blue cheese dressings in pregnancy. Choose dressings without blue cheese, or use cooked blue cheese sauces instead. ^[2]

Is blue cheese safe if baked on pizza?

Yes — blue cheese that has been baked on pizza or in a dish until piping hot is considered safe, because heat inactivates Listeria. ^[4]

Are all blue cheeses unpasteurized?

No. Some blue cheeses are made from pasteurized milk, but even pasteurized soft blue cheese is usually advised against when eaten cold in pregnancy. The safest option is cooked blue cheese only. ^[2]

What about Stilton or hard blue cheese?

Some hard blue cheeses made from pasteurized milk may be lower risk, but guidelines still lean cautious. Many pregnant women choose to only have blue cheese when thoroughly heated.
