Why is jarlsberg safe in pregnancy?
Jarlsberg is a hard cheese. Hard cheeses contain much less moisture than soft cheeses, which makes it very difficult for listeria bacteria to grow in them. The NHS confirms that hard cheeses are safe to eat during pregnancy, including those made with unpasteurised milk, because the risk of listeria is so low.
