"Anything you put in your mouth has to be clean"
I have a comment in mind, but I'll keep quiet on that

I never had any problems when I was there, but then the missus boiled all the water, and we cooked everything ourselves, the only place we ate out was KFC.

When you first arrive, it is not always due to what you eat, in most cases you will actually find it is the jetlag that causes it, as your body adjusts to the new time, pressurised cabin, sleep & eating patterns. It is usually this if you get the craps within 48hrs of leaving the UK.....after that it is something you ate
