traveling with LO?

How long should I wait to take LO to Mexico? Let me add that we would not be staying at a resort, or any "vacation type" spots. We would be staying with my husbands family in a very small, very poor, country setting town. There are scorpions everywhere, but they are not poisonous. Farm animals and wild dogs. (The dogs stay to themselves). I don't want to take her when she's too young because I'm afraid of her getting sick or something because it's a whole different world/way of living over there. What do u guys think?
