Jacqui - I wondered what I'd said before you edited your post!
However, as someone who once contracted salmonella poisoning at a large hotel in Ibiza some years ago I agree totally with patrice. This was a hotel which served all their meals buffet style so if you weren't early down to dinner you had no idea how long the food had been left standing.
Obviously this happens a lot in big hotels and if the food is properly cooked, and kept at the correct temperature, and not for hours on end, all should be ok.
I know it was the hotel because loads of the guests went down with the same symptoms within 24 hours of each other and when they didn't clear a few days after returning home I went to the doc's and got checked out to find it was salmonella. Not very nice
Nor was the flight home with a few fellow sufferers on board!
I also try to avoid large buffet style meals if I can and like my meals freshly cooked and hot!
