The reason that soft cheeses are bad or unsafe to eat during pregnancy is because of the chance that the soft cheeses could contain the bacteria called Listeria.
The listeria can be harmful to the unborn baby and cause death in the baby or other health issues.
Listeria can usually be killed off in the soft cheese if it's heated up and cooked but it's best to just avoid eating any soft cheese or uncooked cheeses during your pregnancy.
Staying away from the soft cheese during pregnancy can be hard but it's worth it to wait until the pregnancy is over and your baby is born before eating any soft or uncooked cheeses.
The baby will be well worth the wait on the cheese.
