It's definitely ok, even some of the very newest NHS leaflets etc say it is. But even with my first pregnancy with my son, I was never too worried with UK eggs. They're not MORE likely to contain salmonella just because you're pregnant, it's just that it'd be worse if they did - but who here has ever had salmonella poisoning from a British (lion marked) egg? You're good, don't worry.
In fact, in another country I've spent time in during my pregnancies where I have family, they found it bizarre that I was avoiding things like seafood, pâté, and too much tea or coffee. They were just like what, we've never heard of this. Haha and their babies are just as likely to be fine as ours. It's good that we're precautions, though, of course.
