Arghh - this drives me nuts. The NHS does not say runny eggs are fine in pregnancy! Not on their website, not in their literature and not the midwife when I asked her!
It's absolutely fine to read up, know the new FSA guidance, understand what lion marked means (vaccinated against the most common strain of salmonella - not all), know why you are at more risk in pregnancy (your immune system is lower to prevent your body rejecting the baby), know what impact it might have on the development of your baby (none as I understand it, it will just make you sick as usual - unlike listeria, which can affect the baby). Then make a balanced decision.
I am 34 weeks pregnant and have yet to fall ill eating runny lion marked eggs. However, my midwife told me not to and the risk is one I'm taking myself. It really bugs me that on any discussion of food in pregnancy on MN people come on to say lion marked eggs are 'fine' when that isn't the advice given by healthcare providers to pregnant women currently.
