Hi!
I often hear about how food in other countries is suspect. It IS a good idea to not drink any water (unless it's bottled) in Mexico, but, beyond that, just because you're in the US doesn't meen your food is safe.
I've never gotten food poisoning in Mexico, and I've bought some local food from some little hole-in-the-wall places.
I was just in MCO, and I got food poisoning, probably at my well-known, higher end, US chain hotel. If it wasn't there, it was at a higher-end national chain restaurant. I wasted a day of vacation being sick, and that's never happened to me in Mexico.
