Is Blue Cheese Safe During Pregnancy? (Updated 2026 Guide)
Updated September 10, 2026
The Answer
Blue cheese needs caution during pregnancy: the clearer choice is to cook it until steaming hot throughout. Soft blue veined cheese should be thoroughly cooked whether made with pasteurized or unpasteurized milk.
The main pregnancy consideration is possible Listeria contamination, not a proven fetal toxicity from the mold used to ripen blue cheese. Prefer pasteurized milk, but do not treat that label as a guarantee that cold soft blue cheese is safe; CDC lists heating soft pasteurized cheeses to 165°F or until steaming hot. Hard blue cheeses are distinct from soft varieties, so if you cannot confirm the type, choose thorough cooking and follow package storage instructions.

Track your pregnancy and check what’s safe
✓ What's Safe
- • Choose blue cheese made with pasteurized milk, while still thoroughly cooking soft blue varieties.
- • Check whether the cheese is a hard or soft blue variety rather than relying on the name alone.
- • For soft pasteurized cheese, use CDC's heating guidance: 165°F or steaming hot throughout.
- • Choose dishes where the blue cheese is heated throughout, not added cold after cooking.
- • Follow package storage and use by instructions, and use clean utensils to prevent recontamination after heating.
✗ What to Avoid
- • Cold soft blue veined cheese, even when the label says pasteurized.
- • Treating a melted surface or lightly warmed cheese as evidence of thorough heating.
- • Cold soft blue cheese crumbled over an otherwise hot meal.
- • Assuming a milk label or ingredient grade certifies that cheese is free from Listeria.
- • Eating cheese that has not been stored according to its package instructions or is past its use by date.
- • Applying the cheese guidance directly to blue cheese dressing, which is a separate finished product.

Your Questions Answered
What cheese is off limits while pregnant?
For blue cheese, avoid eating soft blue veined varieties cold or insufficiently heated. NHS advises thoroughly cooking these cheeses whether they are pasteurized or unpasteurized. Hard blue cheeses are a distinct group, so this is not a blanket restriction on every hard cheese. If you are unsure which type you have, cooking until steaming hot throughout is the conservative practical choice.
Can I eat pasteurized blue cheese cold during pregnancy?
A pasteurized label alone does not universally clear cold soft blue cheese for pregnancy. NHS advises thoroughly cooking soft blue veined cheese even when it is made with pasteurized milk. Prefer pasteurized milk, but also check the cheese type and how it will be prepared.
Is melted blue cheese safe during pregnancy?
Melting alone is not enough to establish that blue cheese has been thoroughly heated. Choose cheese that is steaming hot throughout, not just melted on the surface. For soft pasteurized cheeses, CDC lists heating to 165°F or until steaming hot. A hot meal with cold cheese added afterward does not meet that preparation guidance.
Are hard and soft blue cheeses treated the same during pregnancy?
No hard blue cheeses are distinct from soft blue veined varieties. The advice to thoroughly cook soft blue cheese should not become a blanket rule for all hard cheese. Check the package or ask the seller which type you have. When the type remains uncertain, cooking until steaming hot throughout is the conservative option.
Does this guidance also apply to blue cheese dressing?
Blue cheese dressing is a separate finished product, not equivalent to the cheese itself. We reviewed cheese, not dressing, so this guide does not establish whether a particular dressing is suitable during pregnancy. Check guidance specific to the finished dressing, and do not assume a warm dressing has been thoroughly heated.
Is the mold in blue cheese the pregnancy concern?
The normal mold used to ripen blue cheese should not be described as a proven fetal toxin. The practical pregnancy concern here is possible Listeria contamination and how the cheese is prepared and stored. An ingredient list cannot certify that contamination is absent. Focus on the cheese type, thorough heating where advised, and preventing recontamination afterward.
How to Interpret These Ratings
Our ingredient and category rules generate letter grades from the information recorded in the catalog. Missing ingredients and broad category assignments can affect the result. These grades do not measure your dose, confirm a complete current label, or test a product for contamination.
A high grade is not a guarantee of pregnancy safety. A low grade is not, by itself, proof of harm from every use. Follow the product-specific guidance above, check the actual package, and ask your prenatal clinician about supplements, treatment decisions or uncertain exposures.
