Can You Eat Blue Cheese While Pregnant?
Avoid blue cheese unless it's cooked until steaming — soft blue cheeses can carry listeria.
The full answer
Blue cheeses such as gorgonzola, roquefort, Danish blue, and stilton are usually soft or semi-soft and less acidic, which can let listeria grow — and listeria infection is rare but serious in pregnancy because it can cross the placenta. So uncooked blue cheese is on the avoid list, even when it's pasteurised. The reassuring part is that heat fixes it: blue cheese cooked until steaming hot — melted into a sauce, baked on a tart, or stirred through a hot dish — is safe, because cooking kills listeria. If you're out and a salad arrives topped with cold blue-cheese crumbles or dressing, it's best to leave them or ask for the dish without.
How to eat blue cheese safely
- Cooked until steaming (sauces, melts, bakes): safe
- Skip cold/uncooked blue-cheese crumbles and dressings
- Cooking matters more than pasteurisation here — heat it through
When to avoid: Avoid uncooked blue cheese of any kind; only have it cooked until steaming hot.
Blue Cheese by trimester
| Stage | What changes |
|---|---|
| First trimester | Blue cheese is mould-ripened, which is why it appears in pregnancy guidance. Advice has shifted in some countries toward allowing pasteurised blue cheese, so this is one where local guidance genuinely differs. |
| Second trimester | Unchanged. Cooking it thoroughly resolves the question regardless of which guidance you're following. |
| Third trimester | Same position. A cheese board is the classic situation to think about; a hot sauce or a cooked dish is not. |
Common questions about blue cheese in pregnancy
Can I eat blue cheese while pregnant?
This is one where advice has genuinely changed and varies by country — some guidance now considers pasteurised blue cheese acceptable, while other advice still says avoid. Because it differs, this is worth asking your provider or checking your national guidance rather than relying on a general answer.
Is cooked blue cheese fine?
Cooked until steaming hot, it's generally considered fine under either version of the advice. That covers most sauces, cooked dishes and anything baked.
Why is mould-ripened cheese singled out?
The ripening process produces a less acidic, moister cheese, which is more hospitable to listeria than a hard aged cheese. It's about the conditions inside the cheese rather than the mould itself being harmful.
Pregnancy food-safety basics
Most “can I have this?” questions in pregnancy come down to four things. Listeria — a bacterium that survives the fridge — is why chilled ready-to-eat meats, pâté, and mould-ripened soft cheeses are heated or avoided. Mercury is why certain fish are limited. Caffeine is capped at about 200 mg a day. And alcohol is best avoided entirely, as no safe amount is known. Cooking food until it’s steaming hot kills listeria and most other bugs, which is why “heat until steaming” solves so many of these questions.
