Unlike drier cheeses like parmesan and cheddar which can be stored for a longer period, feta cheese is brined, soft and wet. So, It’s prone to spoilage.

With that being said, pregnant women are not advised to eat feta and other soft cheeses such as mozzarella and brie… especially if you are not sure whether it’s pasteurized.
So, is feta cheese Okay for pregnancy? The answer is ‘maybe’ for pasteurized feta, and ‘no’ for unknown/unpasteurized feta.
In the US, most soft cheeses (99%) you bought from the store are pasteurized, including feta and Greek feta. However, you may not find the pasteurization label on it, or simply forget to check.
Pasteurization can be a little concerning for imported feta cheeses from oversea, or those that obtained from smaller brands or artisanal cheesemakers. Some feta are not fully pasteurized, not regulated, or uses a sub-pasteurization method called thermization which is a similar but weaker heat treatment.
The Food and Drug Administration (FDA) places same restriction on thermized cheese as unpasteurized cheese.
Here is a note from the FDA:
Soft cheeses like Feta… unless they’re made with pasteurized milk. Make sure the label says, “made with pasteurized milk.”The food and drug administration
Unpasteurized cheese meaning a higher chances of harmful bacteria in it. Foodborne illness such as listeriosis can cause miscarriage or even death (1). However In the Europe or some other traditions may look it otherwise as they prefer to use thermized or raw milk instead for a better flavor and nutrient.
It’s hard to deny that pasteurization will inevitably destroy some important vitamins and the pro- raw milk advocate organization continue to promote the benefits of ‘nature’s perfect food’(2). What about your thought?

Does the 60-day-safe-cheese rule applies to feta?
Have you heard about the 60-day rule for cheese?
The 60-day rule means if the cheese has not been aged for 60 days or above, it must be made with pasteurized milk to avoid harmful bacteria. This includes many of the fresh soft cheeses, such as cottage cheese, cream cheese, mascarpone, queso blanco and ricotta. In the US, they have to be pasteurized to be shelved.
If over 60 days old, the cheese can then be made from either pasteurized or unpasteurized milk since aging long enough will kill harmful bacteria.
Feta is usually aged for a minimum of 3 months. However, findings showed listeria survived for 90 days even aged at low pH. Therefore, it’s best to avoid the unpasteurized feta regardless of aging duration.
The key takeaway here is for the pregnant women or anyone with compromised immune system, including children and elderly, to only eat feta made from the pasteurized milk.
