Unpasteurised cheeses imported from abroad or made by small producers are safe to eat in pregnancy provided they are made from cow's milk and are not mould-ripened or blue-veined. The Food Standards Agency states that listeria is present in these cheeses in very low numbers and they are therefore not considered a risk during pregnancy. On the other hand, unpasteurised milk (from any animal) is not considered safe. In the USA, pregnant women are advised to avoid feta cheese because of the risk of listeria, but the feta cheese sold in the UK is considered safe to eat during pregnancy.
