I am 18 weeks pregnant and had eggs royal for breakfast yesterday. The salmon had been frozen but wasn’t cooked. I have noticed that there’s advise not to eat smoked salmon if pregnant. This wasn’t the advice in my last pregnancy. What are the chances of getting listeria? What are the chances baby will get it without me knowing and what will be the consequences for the baby. Is there a way of finding out? Am I panicking for no reason or should I seek medical advice?
