I ate sushi, runny egg and some salami and even some Brie (Australian made therefore pasteurized)

I was very cautious about left overs and food that had been left at room temperature (so mainly food court kind of stuff). I just focussed on freshness, and especially when eating sushi, it was at a restaurant and had just been cut and was still chilled. I think you have more danger from the room temperature rice in a sushi roll, since it is often at room temperature and sitting in a cabinet all day.
