Is it safe to eat aged Swiss cheese while pregnant?

A lot of Swiss cheese is traditionally made from unpasturised milk and should therefore be avoided. If you check the label it will give you more information.

Yes it is safe to eat, all hard unpasturised cheese is perfectly safe to eat, soft cheese regardless of it being pasturised or not, isn't. its all to do with the moisture content that harbers the bacteria. the cheese isn't the problem its the bacteria from your unwashed salad in your home fridge that can causes the bacteria to grow on the cheese. If in doubt got to Waitrose their cheese specialists have qualifications and actually know what they are talking about unlike the medical profession who don't know and ill advise people into thinking because soft cheese is pasturised its ok and it isn't.
