I would read up on each 'problem' food and decide for yourself just how risky it is. I went to France, Wales and the UK when I was preggo with my first and I didn't eat any soft cheese, or any of the wonderful local pate. I carefully chose my one glass of wine per day.
Do I ever wish we'd gone during my second pregnancy! My midwife was really relaxed about foods, gave me some reading to do and urged me to balance risk with life-fulfilment. Her point was that we take calculated risks every day (ever driven on route 2 with those craze MA drivers?) in order to have oppurtunities. Pregnancy is a time to be a little more risk-conscious, but you need to balance baby's needs against your own, just like you will be doing for the whole life of your little one.
Is there a risk of listeria in soft cheese? Yup, but it's unlikely, and a local woman recently lost a pregnancy having conrtacted listeria drinking pasteurized, supposedly safe, milk.
I'd guess that in Italy, where food is revered far more than it is here, you'd be safe by virtue of the fact that they prefer fresher, better quality produce than we do. Eggs need to be hard-cooked only when they come from a mass-producing, high-density, industrial source. Fresh eggs from free, healthy hens have virtually no risks. (You'll find those in Ireland too!)
So, enjoy your trip. Eat well and healthy. Enjoy an occasional chianti, a locally produced proscuitto panini, and a lot of yummy fresh pasta and spring veggies.
One more piece of advice; take lots of pictures of your hand on your tummy. My son LOVES his little album of his Mama-tummy European adventures. When we visit England now, he can tell me where he went 'in you tummy, Mama'.
