Tostitos Dipetizers Four Cheese Queso

FTM here: I bought a thing of Tostitos Dipetizers Real Mexican Four Cheese Queso. It says in the ingredients that all the cheeses are made with pasteurized milk and you are suppose to heat it in the microwave before consuming. It is safe for pregnant women to eat right? (Besides the preservatives. I know those are not healthy. But I just want in general since it's made by Tostitos.)
