Is queso dip safe during pregnancy?

What does the evidence say about queso dip during pregnancy?

1. Many packaged cheeses in the United States are pasteurized, but MotherToBaby advises checking the label. Restaurant queso recipes vary, so pasteurization should be confirmed rather than assumed. 1
2. Some Mexican-style cheeses made from pasteurized milk have still been linked to Listeria infections. Pasteurization and careful handling are separate parts of lowering exposure. 2
3. Heating food to steaming, at least 165°F, kills listeria, and pregnant people are one of the specific groups public health guidance names as being at higher risk from the infection. 2
4. FDA buffet guidance calls for hot food to stay at 140°F or warmer, verified with a food thermometer. Perishables left without hot or cold holding for more than two hours should be discarded; the limit is one hour above 90°F. 3
5. In a reported outbreak involving a chicken, sausage, and rice dish left warm overnight, reheating did not remove the hazard from heat-stable Staphylococcus aureus toxin. Reheating cannot make improperly stored food reliably safe. 4

Is queso dip safe in each trimester?

• First trimester. Queso dip handling matters from early pregnancy. Check the cheese label for pasteurized milk or ask the restaurant about ingredients instead of assuming every cheese blend is pasteurized.
• Second trimester. Queso dip made with pasteurized cheese still needs clean preparation and correct storage. Pasteurization does not exclude contamination later in production or handling.
• Third trimester. The same queso precautions apply later in pregnancy. For parties or shared dishes, check the holding temperature and use fresh serving dishes rather than topping up a bowl that has been sitting out.
