What Guidelines Say

i

Hard cheeses like Parmesan are considered safe during pregnancy, regardless of pasteurization, due to low moisture and high acidity.

Read more details

According to FDA and ACOG guidelines, hard cheeses such as Parmesan, Romano, and Cheddar are categorized as safe for consumption during pregnancy. These cheeses possess a low water content and high acidity, which creates an environment that does not support the growth of Listeria monocytogenes. While the FDA generally recommends pasteurized dairy, an exception is made for hard cheeses; the traditional aging process (typically 60 days or longer) effectively reduces pathogen risks even when unpasteurized milk is used. Parmesan provides significant nutritional benefits, including approximately 330mg of calcium per ounce, which supports fetal skeletal development. Safety is maintained by ensuring the cheese is stored at temperatures below 40°F (4°C) and handled with clean utensils to prevent cross-contamination after opening the original packaging.
