Can I eat pesto while pregnant?

Pesto is generally considered safe during pregnancy. The primary safety considerations involve the raw herbs and the type of cheese used in the recipe. Basil, the primary ingredient, can carry soil-borne pathogens such as Toxoplasma gondii or Listeria monocytogenes if not thoroughly washed. FDA guidelines emphasize washing all produce under running water to mitigate these risks. Traditional pesto utilizes hard cheeses like Parmesan or Pecorino Romano; the FDA and ACOG state that hard, aged cheeses are safe because their low moisture content and acidity inhibit bacterial growth. Commercially processed, shelf-stable jarred pesto is typically pasteurized or treated to eliminate harmful bacteria. For homemade versions, using pasteurized dairy and ensuring pine nuts are fresh prevents foodborne illness. Pesto provides beneficial monounsaturated fats and antioxidants, making it a nutritious option when prepared with standard food safety protocols.
