Mozzarella made from pasteurized milk is safe during pregnancy; unpasteurized versions should be avoided.

Read more details

According to the FDA and ACOG, mozzarella is classified as a safe cheese for consumption during pregnancy provided it is produced from pasteurized milk. Most mozzarella sold in United States supermarkets—including fresh balls in brine, blocks, and shredded varieties—undergoes pasteurization, a heat-treatment process that destroys Listeria monocytogenes. This bacterium is a significant concern during pregnancy because it can cross the placenta, potentially leading to miscarriage or stillbirth. While soft cheeses are often flagged as risky, the high moisture content and low acidity of mozzarella do not pose a threat if the milk source is treated. Guidelines emphasize checking the product label for the word 'pasteurized.' If mozzarella is made from raw milk, it is generally advised to avoid it unless it is cooked until steaming hot (165°F) to ensure any potential pathogens are neutralized.

Safer Choices

Pasteurized Mozzarella

  • Always select mozzarella labeled as made from pasteurized milk to ensure safety.

Cooked Dishes

  • Incorporate pasteurized mozzarella into thoroughly cooked dishes like lasagna or baked ziti, where the cheese reaches high temperatures, further reducing any potential bacterial presence.

Hard Cheeses

  • Opt for hard cheeses like cheddar or Swiss, which are typically made from pasteurized milk and have a lower moisture content, making them less susceptible to bacterial contamination.

Pasteurized fresh mozzarella

  • Labels confirming pasteurization ensure the product is free from harmful bacteria like Listeria.

Low-moisture block mozzarella

  • This variety has a longer shelf life and is almost universally pasteurized in the United States.

Cooked mozzarella

  • Heating cheese until it is bubbling or reaches 165°F, such as on pizza, provides an extra layer of safety.

Pre-packaged shredded mozzarella

  • Commercial shredded products are typically pasteurized and handled in controlled environments to prevent contamination.

Risks & Limits

Unpasteurized Mozzarella

  • Avoid mozzarella made from raw milk due to the risk of *Listeria* contamination.

Soft Cheeses from Unpasteurized Milk

  • Limit consumption of other soft cheeses like feta, Brie, Camembert, blue-veined cheeses, and queso fresco unless they are clearly labeled as made from pasteurized milk.

Unpasteurized (raw) mozzarella

  • Raw milk cheeses carry a higher risk of Listeria and are generally recommended to be avoided during pregnancy.

Mozzarella from open vats

  • Products from farm stands or open containers without clear pasteurization labeling may pose an unknown bacterial risk.
