Cheese during pregnancy: How Pasteurization and Preparation Matter

Cheese can contribute calcium and protein during pregnancy, but the food safety advice depends on the type and how it is prepared. Pasteurisation matters, yet it is not the only detail to check. A soft cheese with a mould rind needs a different decision from a hard cheese.

Start with the type of cheese

Under UK pregnancy guidance, hard cheeses such as cheddar, parmesan and gruyère are allowed whether the milk was pasteurised or unpasteurised. Pasteurised soft cheeses such as cream cheese, cottage cheese, mozzarella and feta are also options when stored and handled correctly.

This does not mean all cheese made from unpasteurised milk is suitable. Check the exact variety and use local guidance where you live, since recommendations can differ. If a label or menu is unclear, ask the shop or restaurant rather than making a decision from appearance alone.

Some soft cheeses need thorough cooking

Soft cheeses with a white mould rind, such as brie or camembert, and soft blue cheeses, such as gorgonzola or roquefort, should be cooked until steaming hot before eating in pregnancy. This applies even when they are made from pasteurised milk.

The concern is the possibility of listeria contamination. Simply warming a cheese or letting it soften does not establish that it has been heated thoroughly. If ordering a dish, ask whether the cheese will be cooked until steaming hot all the way through. Choose a different option if that cannot be confirmed.

Keep storage part of the decision

Follow the packet’s refrigeration and use by instructions, including instructions after opening. Keep food that is ready to eat separate from raw foods. A cheese that is usually suitable still needs safe handling.

For a prepared sandwich or salad containing cheese, keep it chilled and eat it within the stated date. The pregnancy food guide explains the same principles for other meals. Checking type, cooking and storage together is more useful than maintaining a list of brand names.

Know what to do after an uncertain meal

Eating a food that might carry listeria does not mean it was contaminated or that you have an infection. If you feel well but are worried, discuss the details with your midwife or doctor. If you develop a fever, chills, aches or digestive symptoms after a potentially unsafe food, seek urgent medical advice and mention pregnancy.

You can meet calcium needs without eating a cheese you are unsure about. Pasteurised milk or yogurt and suitable fortified alternatives offer other choices. The calcium during pregnancy guide can help you build variety while keeping food safety straightforward.
