Understanding queso fresco in pregnancy

Queso fresco is the tricky kind of cheese, because traditionally it is made from unpasteurised (raw) milk, and soft unpasteurised cheeses are the classic listeria risk in pregnancy. The soft, moist texture is exactly the environment listeria can grow in, even in the fridge. So the raw-milk version is one to avoid.

That does not mean no queso fresco at all. If the label clearly says made with pasteurised milk, it is safe, and cooking it until it is steaming hot (melted into a quesadilla, baked dish or warm sauce) makes it safe regardless. When you are unsure of the source, treat it as raw-milk and skip it, or reach for a pasteurised alternative.

FAQ

Why queso fresco needs a second look

If you love queso fresco, this one stings a little, but it's worth knowing. Traditional queso fresco is a soft, fresh cheese, and when it's made with unpasteurised milk it can carry listeria, a bacteria pregnancy makes you far more vulnerable to. That's the whole reason it lands on the caution list.

The good news: it's an easy fix. Check the label for the word pasteurised, pasteurised queso fresco is fine, and when a restaurant can't confirm, either ask for it cooked into a hot dish (heat destroys listeria) or choose a hard, pasteurised cheese like cheddar instead. See our full soft cheese and feta guides for the same rules across the cheese board.

• Pasteurised queso fresco: safe to enjoy
• Unpasteurised/'fresh from the market': avoid unless cooked until steaming
• Restaurant queso where they can't confirm: ask for it cooked, or swap it
• Keep it well chilled and eat before the use-by date

Craving it doesn't make you careless, you're checking, which is exactly right. Keep a daily prenatal vitamin going for your daily calcium and folate, and you're covered whichever cheese you choose.
