Can you eat monterey jack while pregnant?
SafeYes, Monterey Jack is safe during pregnancy, in sandwiches, quesadillas, nachos and burgers. It is a semi-hard cheese and US supermarket versions are pasteurized, so there is no Listeria risk.
Why
Listeria in cheese comes overwhelmingly from soft, high-moisture cheeses made with unpasteurized milk, which is what the CDC's guidance for pregnant women singles out. Monterey Jack is neither: it is a pressed semi-hard cheese, and commercial jack sold in the United States is made from pasteurized milk, which kills Listeria before the cheese is even formed. The NHS puts cheeses of this type on the safe list in pregnancy. Pepper jack and Colby Jack are the same cheese with additions, so they are safe too. Glance at the label once if you are buying from a specialty counter, and you are done.

Frequently asked questions
Is pepper jack safe while pregnant?
Yes. Pepper jack is Monterey Jack with chili peppers mixed in, and the peppers change nothing about food safety. The only thing they might change is your heartburn, which tends to get worse later in pregnancy.
Can I eat melted jack cheese in restaurant quesadillas and nachos?
Yes, and melted is the easiest case of all. The cheese is already pasteurized, and the heat removes any doubt. Order it as you normally would.
Is Monterey Jack the same as queso fresco?
No, and the difference matters. Queso fresco is a soft fresh cheese that has been linked to Listeria outbreaks when made with unpasteurized milk, so it needs a pasteurized label. Monterey Jack is semi-hard and pasteurized, so it does not carry that risk.
