Can you eat queso fresco while pregnant?
Not advisedSkip cold queso fresco during pregnancy, even pasteurized: it has caused Listeria outbreaks after pasteurization. Heated until steaming hot, about 165 F, it is safe.
Why
Queso fresco is the one cheese where a pasteurized label is not enough. The CDC warns pregnant women off unheated queso fresco-type cheeses specifically because Hispanic-style fresh cheeses have repeatedly caused Listeria outbreaks in the US, including batches made from pasteurized milk that were contaminated during cheesemaking. The CDC also notes pregnant Hispanic women face a much higher listeriosis risk, largely through these cheeses. The same CDC guidance offers the fix: heated to 165 F or until steaming hot, queso fresco is safe, so cooked dishes keep it on the menu.
By trimester
Listeriosis is most dangerous in the third trimester, when it can trigger preterm labor or stillbirth even from a mild-feeling infection, so the no-cold-queso-fresco rule matters right up to delivery.
Safer alternatives
- Queso fresco melted into steaming hot dishes
- Pasteurized feta, the closest safe crumble
- Grated parmesan or cotija anejo for topping

Frequently asked questions
Why is pasteurized queso fresco still risky?
Because the outbreaks traced to these cheeses often involved contamination after pasteurization, during forming and packing: fresh, moist, low-salt cheese is an ideal surface for Listeria to grow on. That is why the CDC's advice is keyed to the cheese style, not the milk.
Can I eat queso fresco on enchiladas or in quesadillas?
Yes, when the dish comes out steaming hot so the cheese itself has been heated through, per the CDC's 165 F guidance. Cheese sprinkled cold on top after cooking does not count; add it before the heat.
Does the rule cover queso blanco and panela too?
Yes. Queso blanco, panela and fresh crumbly cotija are the same style of Hispanic fresh cheese and follow the same rule: skip them cold, enjoy them heated until steaming.
