Mozzarella: Every Food Safety Answer

Written by Jordan Morley Β· Reviewed against NHS, FSA and USDA FoodKeeper guidance Β· Last updated 28 October 2026

This page pulls together the 6 mozzarella answers on the site: how long it keeps, whether you can freeze it, where it stands in pregnancy and what applies while breastfeeding. The table gives the short answer for each; the page behind each row gives the full reasoning, the source and the exceptions.

In pregnancy: Yes β€” Mozzarella is safe during pregnancy as long as it is made from pasteurised milk. Check the label for the word pasteurised.

Worth knowing: Soft cheese is higher in water, so it separates and turns grainy or crumbly when thawed. Safety is unaffected, but use it in cooking (baked dishes, sauces, pizza) rather than serving it on a cheeseboard.
